State of the world in 2050

Some things are getting better, some worse. 2050 will be neither dystopian nor utopian. A balance of good and bad not unlike today, but with different goods and bads, and slightly better overall. More detail? Okay, for most of my followers, this will mostly collate things you may know already, but there’s no harm in a refresher Futures 101.

Health

We will have cost-effective and widespread cures or control for most cancers, heart disease, diabetes, dementia and most other killers. Quality-of-life diseases such as arthritis will also be controllable or curable. People will live longer and remain healthier for longer, with an accelerated decline at the end.

On the bad side, new diseases will exist, including mutated antibiotic-resistant versions of existing ones. There will still be occasional natural flu mutations and other viruses, and there will still be others arising from contacts between people and other animals that are more easily spread due to increased population, urbanization and better mobility. Some previously rare diseases will become big problems due to urbanization and mobility. Urbanization will be a challenge.

However, diagnostics will be faster and better, we will no longer be so reliant on antibiotics to fight back, and sterilisation techniques for hospitals will be much improved. So even with greater challenges, we will be able to cope fine most of the time with occasional headlines from epidemics.

A darker side is the increasing prospect for bio-terrorism, with man-made viruses deliberately designed to be highly lethal, very contagious and to withstand most conventional defenses, optimized for maximum and rapid spread by harnessing mobility and urbanization. With pretty good control or defense against most natural threats, this may well be the biggest cause of mass deaths in 2050. Bio-warfare is far less likely.

Utilizing other techs, these bio-terrorist viruses could be deployed by swarms of tiny drones that would be hard to spot until too late, and of course these could also be used with chemical weapons such as use of nerve gas. Another tech-based health threat is nanotechnology devices designed to invade the body, damage of destroy systems or even control the brain. It is easy to detect and shoot down macro-scale deployment weapons such as missiles or large drones but far harder to defend against tiny devices such as midge-sized drones or nanotech devices.

The overall conclusion on health is that people will mostly experience much improved lives with good health, long life and a rapid end. A relatively few (but very conspicuous) people will fall victim to terrorist attacks, made far more feasible and effective by changing technology and demographics.

Loneliness

An often-overlooked benefit of increasing longevity is the extending multi-generational family. It will be commonplace to have great grandparents and great-great grandparents. With improved health until near their end, these older people will be seen more as welcome and less as a burden. This advantage will be partly offset by increasing global mobility, so families are more likely to be geographically dispersed.

Not everyone will have close family to enjoy and to support them. Loneliness is increasing even as we get busier, fuller lives. Social inclusion depends on a number of factors, and some of those at least will improve. Public transport that depends on an elderly person walking 15 minutes to a bus stop where they have to wait ages in the rain and wind for a bus on which they are very likely to catch a disease from another passenger is really not fit for purpose. Such primitive and unsuitable systems will be replaced in the next decades by far more socially inclusive self-driving cars. Fleets of these will replace buses and taxis. They will pick people up from their homes and take them all the way to where they need to go, then take them home when needed. As well as being very low cost and very environmentally friendly, they will also have almost zero accident rates and provide fast journey times thanks to very low congestion. Best of all, they will bring easier social inclusion to everyone by removing the barriers of difficult, slow, expensive and tedious journeys. It will be far easier for a lonely person to get out and enjoy cultural activity with other people.

More intuitive social networking, coupled to augmented and virtual reality environments in which to socialize will also mean easier contact even without going anywhere. AI will be better at finding suitable companions and lovers for those who need assistance.

Even so, some people will not benefit and will remain lonely due to other factors such as poor mental health, lack of social skills, or geographic isolation. They still do not need to be alone. 2050 will also feature large numbers of robots and AIs, and although these might not be quite so valuable to some as other human contact, they will be a pretty good substitute. Although many will be functional, cheap and simply fit for purpose, those designed for companionship or home support functions will very probably look human and behave human. They will have good intellectual and emotional skills and will be able to act as a very smart executive assistant as well as domestic servant and as a personal doctor and nurse, even as a sex partner if needed.

It would be too optimistic to say we will eradicate loneliness by 2050 but we can certainly make a big dent in it.

Poverty

Technology progress will greatly increase the size of the global economy. Even with the odd recession our children will be far richer than our parents. It is reasonable to expect the total economy to be 2.5 times bigger than today’s by 2050. That just assumes an average growth of about 2.5% which I think is a reasonable estimate given that technology benefits are accelerating rather than slowing even in spite of recent recession.

While we define poverty level as a percentage of average income, we can guarantee poverty will remain even if everyone lived like royalty. If average income were a million dollars per year, 60% of that would make you rich by any sensible definition but would still qualify as poverty by the ludicrous definition based on relative income used in the UK and some other countries. At some point we need to stop calling people poor if they can afford healthy food, pay everyday bills, buy decent clothes, have a decent roof over their heads and have an occasional holiday. With the global economy improving so much and so fast, and with people having far better access to markets via networks, it will be far easier for people everywhere to earn enough to live comfortably.

In most countries, welfare will be able to provide for those who can’t easily look after themselves at a decent level. Ongoing progress of globalization of compassion that we see today will likely make a global welfare net by 2050. Everyone won’t be rich, and some won’t even be very comfortable, but I believe absolute poverty will be eliminated in most countries, and we can ensure that it will be possible for most people to live in dignity. I think the means, motive and opportunity will make that happen, but it won’t reach everyone. Some people will live under dysfunctional governments that prevent their people having access to support that would otherwise be available to them. Hopefully not many. Absolute poverty by 2050 won’t be history but it will be rare.

In most developed countries, the more generous welfare net might extend to providing a ‘citizen wage’ for everyone, and the level of that could be the same as average wage is today. No-one need be poor in 2050.

Environment

The environment will be in good shape in 2050. I have no sympathy with doom mongers who predict otherwise. As our wealth increases, we tend to look after the environment better. As technology improves, we will achieve a far higher standards of living while looking after the environment. Better mining techniques will allow more reserves to become economic, we will need less resource to do the same job better, reuse and recycling will make more use of the same material.

Short term nightmares such as China’s urban pollution levels will be history by 2050. Energy supply is one of the big contributors to pollution today, but by 2050, combinations of shale gas, nuclear energy (uranium and thorium), fusion and solar energy will make up the vast bulk of energy supply. Oil and unprocessed coal will mostly be left in the ground, though bacterial conversion of coal into gas may well be used. Oil that isn’t extracted by 2030 will be left there, too expensive compared to making the equivalent energy by other means. Conventional nuclear energy will also be on its way to being phased out due to cost. Energy from fusion will only be starting to come on stream everywhere but solar energy will be cheap to harvest and high-tech cabling will enable its easier distribution from sunny areas to where it is needed.

It isn’t too much to expect of future governments that they should be able to negotiate that energy should be grown in deserts, and food crops grown on fertile land. We should not use fertile land to place solar panels, nor should we grow crops to convert to bio-fuel when there is plenty of sunny desert of little value otherwise on which to place solar panels.

With proper stewardship of agricultural land, together with various other food production technologies such as hydroponics, vertical farms and a lot of meat production via tissue culturing, there will be more food per capita than today even with a larger global population. In fact, with a surplus of agricultural land, some might well be returned to nature.

In forests and other ecosystems, technology will also help enormously in monitoring eco-health, and technologies such as genetic modification might be used to improve viability of some specie otherwise threatened.

Anyone who reads my blog regularly will know that I don’t believe climate change is a significant problem in the 2050 time frame, or even this century. I won’t waste any more words on it here. In fact, if I have to say anything, it is that global cooling is more likely to be a problem than warming.

Food and Water

As I just mentioned in the environment section, we will likely use deserts for energy supply and fertile land for crops. Improving efficiency and density will ensure there is far more capability to produce food than we need. Many people will still eat meat, but some at least will be produced in factories using processes such as tissue culturing. Meat pastes with assorted textures can then be used to create a variety of forms of processed meats. That might even happen in home kitchens using 3D printer technology.

Water supply has often been predicted by futurists as a cause of future wars, but I disagree. I think that progress in desalination is likely to be very rapid now, especially with new materials such as graphene likely to come on stream in bulk.  With easy and cheap desalination, water supply should be adequate everywhere and although there may be arguments over rivers I don’t think the pressures are sufficient by themselves to cause wars.

Privacy and Freedom

In 2016, we’re seeing privacy fighting a losing battle for survival. Government increases surveillance ubiquitously and demands more and more access to data on every aspect of our lives, followed by greater control. It invariably cites the desire to control crime and terrorism as the excuse and as they both increase, that excuse will be used until we have very little privacy left. Advancing technology means that by 2050, it will be fully possible to implement thought police to check what we are thinking, planning, desiring and make sure it conforms to what the authorities have decided is appropriate. Even the supposed servant robots that live with us and the AIs in our machines will keep official watch on us and be obliged to report any misdemeanors. Back doors for the authorities will be in everything. Total surveillance obliterates freedom of thought and expression. If you are not free to think or do something wrong, you are not free.

Freedom is strongly linked to privacy. With laws in place and the means to police them in depth, freedom will be limited to what is permitted. Criminals will still find ways to bypass, evade, masquerade, block and destroy and it hard not to believe that criminals will be free to continue doing what they do, while law-abiding citizens will be kept under strict supervision. Criminals will be free while the rest of us live in a digital open prison.

Some say if you don’t want to do wrong, you have nothing to fear. They are deluded fools. With full access to historic electronic records going back to now or earlier, it is not only today’s laws and guidelines that you need to be compliant with but all the future paths of the random walk of political correctness. Social networks can be fiercer police than the police and we are already discovering that having done something in the distant past under different laws and in different cultures is no defense from the social networking mobs. You may be free technically to do or say something today, but if it will be remembered for ever, and it will be, you also need to check that it will probably always be praiseworthy.

I can’t counterbalance this section with any positives. I’ve side before that with all the benefits we can expect, we will end up with no privacy, no freedom and the future will be a gilded cage.

Science and the arts

Yes they do go together. Science shows us how the universe works and how to do what we want. The arts are what we want to do. Both will flourish. AI will help accelerate science across the board, with a singularity actually spread over decades. There will be human knowledge but a great deal more machine knowledge which is beyond un-enhanced human comprehension. However, we will also have the means to connect our minds to the machine world to enhance our senses and intellect, so enhanced human minds will be the norm for many people, and our top scientists and engineers will understand it. In fact, it isn’t safe to develop in any other way.

Science and technology advances will improve sports too, with exoskeletons, safe drugs, active skin training acceleration and virtual reality immersion.

The arts will also flourish. Self-actualization through the arts will make full use of AI assistance. a feeble idea enhanced by and AI assistant can become a work of art, a masterpiece. Whether it be writing or painting, music or philosophy, people will be able to do more, enjoy more, appreciate more, be more. What’s not to like?

Space

by 2050, space will be a massive business in several industries. Space tourism will include short sub-orbital trips right up to lengthy stays in space hotels, and maybe on the moon for the super-rich at least.

Meanwhile asteroid mining will be under way. Some have predicted that this will end resource problems here on Earth, but firstly, there won’t be any resource problems here on Earth, and secondly and most importantly, it will be far too expensive to bring materials back to Earth, and almost all the resources mined will be used in space, to make space stations, vehicles, energy harvesting platforms, factories and so on. Humans will be expanding into space rapidly.

Some of these factories and vehicles and platforms and stations will be used for science, some for tourism, some for military purposes. Many will be used to offer services such as monitoring, positioning, communications just as today but with greater sophistication and detail.

Space will be more militarized too. We can hope that it will not be used in actual war, but I can’t honestly predict that one way or the other.

 

Migration

If the world around you is increasingly unstable, if people are fighting, if times are very hard and government is oppressive, and if there is a land of milk and honey not far away that you can get to, where you can hope for a much better, more prosperous life, free of tyranny, where instead of being part of the third world, you can be in the rich world, then you may well choose to take the risks and traumas associated with migrating. Increasing population way ahead of increasing wealth in Africa, and a drop in the global need for oil will both increase problems in the Middle East and North Africa. Add to that vicious religious sectarian conflict and a great many people will want to migrate indeed. The pressures on Europe and America to accept several millions more migrants will be intense.

By 2050, these regions will hopefully have ended their squabbles, and some migrants will return to rebuild, but most will remain in their new homes.

Most of these migrants will not assimilate well into their new countries but will mainly form their own communities where they can have a quite separate culture, and they will apply pressure to be allowed to self-govern. A self-impose apartheid will result. It might if we are lucky gradually diffuse as religion gradually becomes less important and the western lifestyle becomes more attractive. However, there is also a reinforcing pressure, with this self-exclusion and geographic isolation resulting in fewer opportunities, less mixing with others and therefore a growing feeling of disadvantage, exclusion and victimization. Tribalism becomes reinforced and opportunities for tension increase. We already see that manifested well in  the UK and other European countries.

Meanwhile, much of the world will be prosperous, and there will be many more opportunities for young capable people to migrate and prosper elsewhere. An ageing Europe with too much power held by older people and high taxes to pay for their pensions and care might prove a discouragement to stay, whereas the new world may offer increasing prospects and lowering taxes, and Europe and the USA may therefore suffer a large brain drain.

Politics

If health care is better and cheaper thanks to new tech and becomes less of a political issue; if resources are abundantly available, and the economy is healthy and people feel wealthy enough and resource allocation and wealth distribution become less of a political issue; if the environment is healthy; if global standards of human rights, social welfare and so on are acceptable in most regions and if people are freer to migrate where they want to go; then there may be a little less for countries to fight over. There will be a little less ‘politics’ overall. Most 2050 political arguments and debates will be over social cohesion, culture, generational issues, rights and so on, not health, defence, environment, energy or industry

We know from history that that is no guarantee of peace. People disagree profoundly on a broad range of issues other than life’s basic essentials. I’ve written a few times on the increasing divide and tensions between tribes, especially between left and right. I do think there is a strong chance of civil war in Europe or the USA or both. Social media create reinforcement of views as people expose themselves only to other show think the same, and this creates and reinforces and amplifies an us and them feeling. That is the main ingredient for conflict and rather than seeing that and trying to diffuse it, instead we see left and right becoming ever more entrenched in their views. The current problems we see surrounding Islamic migration show the split extremely well. Each side demonizes the other, extreme camps are growing on both sides and the middle ground is eroding fast. Our leaders only make things worse by refusing to acknowledge and address the issues. I suggested in previous blogs that the second half of the century is when tensions between left and right might result in the Great Western War, but that might well be brought forward a decade or two by a long migration from an unstable Middle East and North Africa, which looks to worsen over the next decade. Internal tensions might build for another decade after that accompanied by a brain drain of the most valuable people, and increasing inter-generational tensions amplifying the left-right divide, with a boil-over in the 2040s. That isn’t to say we won’t see some lesser conflicts before then.

I believe the current tensions between the West, Russia and China will go through occasional ups and downs but the overall trend will be towards far greater stability. I think the chances of a global war will decrease rather than increase. That is just as well since future weapons will be far more capable of course.

So overall, the world peace background will improve markedly, but internal tensions in the West will increase markedly too. The result is that wars between countries or regions will be less likely but the likelihood of civil war in the West will be high.

Robots and AIs

I mentioned robots and AIs in passing in the loneliness section, but they will have strong roles in all areas of life. Many that are thought of simply as machines will act as servants or workers, but many will have advanced levels of AI (not necessarily on board, it could be in the cloud) and people will form emotional bonds with them. Just as important, many such AI/robots will be so advanced that they will have relationships with each other, they will have their own culture. A 21st century version of the debates on slavery is already happening today for sentient AIs even though we don’t have them yet. It is good to be prepared, but we don’t know for sure what such smart and emotional machines will want. They may not want the same as our human prejudices suggest they will, so they will need to be involved in debate and negotiation. It is almost certain that the upper levels of AIs and robots (or androids more likely) will be given some rights, to freedom from pain and abuse, ownership of their own property, a degree of freedom to roam and act of their own accord, the right to pursuit of happiness. They will also get the right to government representation. Which other rights they might get is anyone’s guess, but they will change over time mainly because AIs will evolve and change over time.

OK, I’ve rambled on long enough and I’ve addressed some of the big areas I think. I have ignored a lot more, but it’s dinner time.

A lot of things will be better, some things worse, probably a bit better overall but with the possibility of it all going badly wrong if we don’t get our act together soon. I still think people in 2050 will live in a gilded cage.

2016 – The Bright Side

Having just blogged about some of the bad scenarios for next year (scenarios are just  explorations of things that might or could happen, not things that actually will, those are called predictions), Len Rosen’s comment stimulated me to balance it with a nicer look at next year. Some great things will happen, even ignoring the various product release announcements for new gadgets. Happiness lies deeper than the display size on a tablet. Here are some positive scenarios. They might not happen, but they might.

1 Middle East sorts itself out.

The new alliance formed by Saudi Arabia turns out to be a turning point. Rising Islamophobia caused by Islamist around the world has sharpened the view of ISIS and the trouble in Syria with its global consequences for Islam and even potentially for world peace. The understanding that it could get even worse, but that Western powers can’t fix trouble in Muslim lands due to fears of backlash, the whole of the Middle East starts to understand that they need to sort out their tribal and religious differences to achieve regional peace and for the benefit of Muslims everywhere. Proper discussions are arranged, and with the knowledge that a positive outcome must be achieved, success means a strong alliance of almost all regional powers, with ISIS and other extremist groups ostracized, then a common army organised to tackle and defeat them.

2 Quantum computation and AI starts to prove useful in new drug design

Google’s wealth and effort with its quantum computers and AI, coupled to IBM’s Watson, Facebook, Apple and Samsung’s AI efforts, and Elon Musk’s new investment in open-AI drive a positive feedback loop in computing. With massive returns on the horizon by making people’s lives easier, and with ever-present fears of Terminator in the background, the primary focus is to demonstrate what it could mean for mankind. Consequently, huge effort and investment is focused on creating new drugs to cure cancer, aids and find generic replacements for antibiotics. Any one of these would be a major success for humanity.

3 Major breakthrough in graphene production

Graphene is still the new wonder-material. We can’t make it in large quantities cheaply yet, but already the range of potential uses already proven for it is vast. If a breakthrough brings production cost down by an order of magnitude or two then many of those uses will be achievable. We will be able to deliver clean and safe water to everyone, we’ll have super-strong materials, ultra-fast electronics, active skin, better drug delivery systems, floating pods, super-capacitors that charge instantly as electric cars drive over a charging unit on the road surface, making batteries unnecessary. Even linear induction motor mats to replace self-driving cars with ultra-cheap driver-less pods. If the breakthrough is big enough, it could even start efforts towards a space elevator.

4 Drones

Tiny and cheap drones could help security forces to reduce crime dramatically. Ignoring for now possible abuse of surveillance, being able to track terrorists and criminals in 3D far better than today will make the risk of being caught far greater. Tiny pico-drones dropped over Syria and Iraq could pinpoint locations of fighters so that they can be targeted while protecting innocents. Environmental monitoring would also benefit if billions of drones can monitor ecosystems in great detail everywhere at the same time.

5 Active contact lens

Google has already prototyped a very primitive version of the active contact lens, but they have been barking up the wrong tree. If they dump the 1-LED-per-Pixel approach, which isn’t scalable, and opt for the far better approach of using three lasers and a micro-mirror, then they could build a working active contact lens with unlimited resolution. One in each eye, with an LCD layer overlaid, and you have a full 3D variably-transparent interface for augmented reality or virtual reality. Other displays such as smart watches become unnecessary since of course they can all be achieved virtually in an ultra-high res image. All the expense and environmental impact of other displays suddenly is replaced by a cheap high res display that has an environmental footprint approaching zero. Augmented reality takes off and the economy springs back to life.

6 Star Wars stimulates renewed innovation

Engineers can’t watch a film without making at least 3 new inventions. A lot of things on Star Wars are entirely feasible – I have invented and documented mechanisms to make both a light saber and the land speeder. Millions of engineers have invented some way of doing holographic characters. In a world that seems full of trouble, we are fortunate that some of the super-rich that we criticise for not paying as much taxes as we’d like are also extremely good engineers and have the cash to back up their visions with real progress. Natural competitiveness to make the biggest contribution to humanity will do the rest.

7 Europe fixes itself

The UK is picking the lock on the exit door, others are queuing behind. The ruling bureaucrats finally start to realize that they won’t get their dream of a United States of Europe in quite the way they hoped, that their existing dream is in danger of collapse due to a mismanaged migrant crisis, and consequently the UK renegotiation stimulates a major new treaty discussion, where all the countries agree what their people really want out of the European project, rather than just a select few. The result is a reset. A new more democratic European dream emerges that the vest majority of people actually wants. Agreement on progress to sort out the migrant crisis is a good test and after that, a stronger, better, more vibrant Europe starts to emerge from the ashes with a renewed vigor and rapidly recovering economy.

8 Africa rearranges boundaries to get tribal peace

Breakthrough in the Middle East ripples through North Africa resulting in the beginnings of stability in some countries. Realization that tribal conflicts won’t easily go away, and that peace brings prosperity, boundaries are renegotiated so that different people can live in and govern their own territories. Treaties agree fair access to resources independent of location.

9 The Sahara become Europe’s energy supply

With stable politics finally on the horizon, energy companies re-address the idea of using the Sahara as a solar farm. Local people earn money by looking after panels, keeping them clean and in working order, and receive welcome remuneration, bringing prosperity that was previously beyond them. Much of this money in turn is used to purify water, irrigating deserts and greening them, making a better food supply while improving the regional climate and fixing large quantities of CO2. Poverty starts to reduce as the environment improves. Much of this is replicated in Central and South America.

10 World Peace emerges

By fighting alongside in the Middle East and managing to avoid World War 3, a very positive relationship between Russia and the West emerges. China meanwhile, makes some of the energy breakthroughs needed to get solar efficiency and cost down below oil cost. This forces the Middle East to also look Westward for new markets and to add greater drive to their regional peace efforts to avoid otherwise inevitable collapse. Suddenly a world that was full of wars becomes one where all countries seem to be getting along just fine, all realizing that we only have this one world and one life and we’d better not ruin it.

Networked telescopes

A very short one since I am still recovering from a painful trapped nerve that has prevented me writing. Anyway, the best ideas are often the simplest. I re-discovered this one in a 2008 article I wrote but I don’t think it has been done yet and it easily could.

So you buy a telescope for use at home. You point it up at a planet or a star. It probably does a magnification of a few hundred. Why not add a digital zoom that is linked to networked images from large telescope such as Hubble? When you reach the limits of your cheaper version, you see images from more expensive better ones. You also could swap to radio or IR or xray images just as easily. Adding that networked function would be fairly simple and cheap, maybe adding a few tens of dollars even to do it well.

Naturally, you could add networked zoom to cameras too, for landscapes and beauty spots anyway.

You could just make a fully digital telescope of course that has no real telescope function at all, just seeming to be one, and working the same way except that ll the images it provides are digital, using direction tracking to pull up the right one.

Ok, my arm hurts again.

 

Paris – Climate Change v Islamism. Which problem is biggest?

Imagine you are sitting peacefully at home watching a movie with your family. A few terrorists with guns burst in. They start shooting. What is your reaction?

Option A) you tell your family not to do anything but to continue watching TV, because reacting would be giving in to the terrorists – they want you to be angry and try to attack them, but you are the better person, you have the moral superiority and won’t stoop to their level. Anyway, attacking them might anger them more and they might be even more violent. You tell your family they should all stick together and show the terrorists they can’t win and can’t change your way of life by just carrying on as before. You watch as one by one, each of your kids is murdered, determined to occupy the moral high ground until they shoot you too.

Option B) you understand that what the terrorists want is for you and your family to be dead. So you grab whatever you can that might act as some sort of weapon and rush at the terrorists, trying to the end to disarm them and protect your family.  If you survive, you then do all you can to prevent other terrorists from coming into your home. Then you do all you can to identify where they are coming from and root them out.

The above choice is a little simplistic but it highlights the key points of the two streams of current opinion on the ‘right’ response.

Option B recognizes that you have to remain alive to defend your principles. Once you’ve dealt with the threat, then you are free to build as many ivory towers and moral pedestals as you want. Option A simply lets the terrorists win.

There is no third option for discussing it peacefully over a nice cup of tea, no option for peace and love and mutual respect for all. ISIS are not interested in peace and love. They are barbarians with the utmost contempt for civilization who want to destroy everything that doesn’t fit into their perverted interpretation of an Islamic world. However, ISIS is just one Islamist terror group of course and if we are successful in conquering them, and then Al Qaeda and Boko Haram, and so on, other Islamist groups will emerge. Islamism is the problem, ISIS is just the worst current group. We need to deal with it.

I’ll draw out some key points from my previous blogs. If you want more detail on the future of ISIS look at https://timeguide.wordpress.com/2015/07/13/the-future-of-isis/

The situation in Europe shows a few similarities with the IRA conflict, with the advantage today that we are still in the early stages of Islamist violence. In both cases, the terrorists themselves are mostly no-hoper young men with egos out of alignment with their personal reality. Yes there are a few women too. They desperately want to be respected, but with no education and no skills, a huge chip on their shoulder and a bad attitude, ordinary life offers them few opportunities. With both ISIS and the IRA, the terrorists are drawn from a community that considers itself disadvantaged. Add a hefty amount of indoctrination about how terribly unfair the world is, the promise of being a hero, going down in history as a martyr and the promise of 72 virgins to play with in the afterlife, and the offer to pick up a gun or a knife apparently seems attractive to some. The IRA recruited enough fighters even without the promise of the virgins.

The IRA had only about 300 front-line terrorists at any time, but they came from the nationalist community of which an estimated 30% of people declared some sympathy for them. Compare that with a BBC survey earlier this year that found that in the aftermath of the Charlie Hebdo attacks, only 68% of Muslims agreed with the statement “Acts of violence against those who publish images of the Prophet Mohammed can never be justified”. 68% and 70% are pretty close, so I’ll charitably accept that the 68% were being honest and not simply trying to disassociate themselves from the Paris massacre. The overwhelming majority of British Muslims rejecting violence – two thirds in the BBC survey, is entirely consistent with other surveys on Muslim attitudes around the world, and probably a reasonable figure for Muslims across Europe. Is the glass half full or half empty? Your call.

The good news is the low numbers that become actual front-line terrorists. Only 0.122% of the nationalist community in Northern Ireland at any particular time were front-line IRA terrorists. Now that ISIS are asking potential recruits not to go to Syria but to stay where they are and do their thing there, we should consider how many there might be. If we are lucky and the same 0.122% applies to our three million UK Muslims, then about 3600 are potential Islamist terrorists. That’s about 12 times bigger than the IRA problem if ISIS or other Islamist groups get their acts together. With 20 million Muslims in Europe, that would make for potentially 24,000 Islamist terrorists, or 81 IRAs to put it another way. Most can travel freely between countries.

What of immigration then? People genuinely fleeing violence presumably have lower support for it, but they are only a part of the current influx. Many are economic migrants and they probably conform more closely to the norm. We also know that some terrorists are hiding among other migrants, and indeed at least two of those were involved in the latest Paris massacre. Most of the migrants are young men, so that would tend to skew the problem upwards too. With forces acting in both directions, it’s probably not unreasonable as a first guess to assume the same overall support levels. According to the BBC, 750,000 have entered Europe this year, so that means another 900 potential terrorists were likely in their midst. Europe is currently importing 3 IRAs every year.

Meanwhile, it is rather ironic that many of the current migrants are coming because Angela Merkel felt guilty about the Holocaust. Many Jews are now leaving Europe because they no longer feel safe because of the rapidly rising numbers of attacks by the Islamists she has encouraged to come.

So, the first Paris issue is Islamism, already at 81 potential IRAs and growing at 3 IRAs per year, plus a renewed exodus of Jews due to widespread increasing antisemitism.

So, to the other Paris issue, climate change. I am not the only one annoyed by the hijacking of the environment by leftist pressure groups, because the poor quality of analysis and policies resulting from that pressure ultimately harms both the environment and the poor.

The world has warmed since the last ice age. Life has adjusted throughout to that continuing climate change. Over the last century, sea level has steadily increased, and is still increasing at the same rate now. The North Pole ice has shrunk, to 8.5% to 11% below normal at the moment depending whose figures you look at, but it certainly isn’t disappearing any time soon. However, Antarctic sea ice  has grown to 17% to 25% above normal again depending whose figures you look at, so there is more ice than normal overall. Temperature has also increased over the last century, with a few spurts and a few slowdowns. The last spurt was late 70s to late 90s, with a slowdown since. CO2 levels have rocketed up relentlessly, but satellite-measured temperature hasn’t moved at all since 1998. Only when figures are tampered with is any statistically significant rise visible.

Predictions by climate models have almost all been far higher than the empirical data. In any other branch of science, that would mean throwing theories away and formulating better ones. In climate science, numerous adjustments by alleged ‘climate scientists’ show terrible changes ahead; past figures have invariably been adjusted downwards and recent ones upwards to make the rises seem larger. Climate scientists have severely damaged the reputation of science in every field. The public now distrusts all scientists less and disregard for scientific advice in lifestyle, nutrition, exercise and medication will inevitably lead to an increase in deaths.

Everyone agrees that CO2 is a greenhouse gas and increases will have a forcing effect on temperature, but there is strong disagreement about the magnitude of that effect, the mechanisms and magnitudes of the feedback processes throughout the environmental system, and both the mechanisms and magnitudes of a wide range of natural effects. It is increasingly obvious that climate scientists only cover a subset of the processes affecting climate, but they seem contemptuous of science in other disciplines such as astrophysics that cover important factors such as solar cycles. There is a strong correlation between climate and solar cycles historically but the mechanisms are complex and not yet fully understood. It is also increasingly obvious that many climate scientists are less concerned about the scientific integrity of their ‘research’ than maintaining a closed shop, excluding those who disagree with them, getting the next grant or pushing a political agenda.

Empirical data suggests that the forcing factor of CO2 itself is not as high as assumed in most models, and the very many feedbacks are far more complex than assumed in most models.

CO2 is removed from the environment by natural processes of adaptation faster than modeled – e.g. plants and algae grow faster, and other natural processes such as solar or ocean cycles have far greater effects than assumed in the models. Recent research suggests that it has a ‘half-life’ in the atmosphere only of around 40 years, not the 1000 years claimed by ‘climate scientists’. That means that the problem will go away far faster when we fix it than has been stated.

CO2 is certainly a greenhouse gas, and we should not be complacent about generating it, but on current science (before tampering) it seems there is absolutely no cause for urgent action. It is right to look to future energy sources and move away from fossil fuels, which also cause other large environmental problems, not least of which the particulates that kill millions of people every year. Meanwhile, we should expedite movement from coal and oil to low carbon fossil fuels such as shale gas.

As is often observed, sunny regions such as the Sahara could easily produce enough solar energy for all of Europe, but there is no great hurry so we can wait for the technology to become sufficiently cheap and for the political stability in appropriate areas to be addressed so that large solar farms can be safely developed and supply maintained. Meanwhile, southern Europe is reasonably sunny, politically stable and needs cash. Other regions also have sunny deserts to support them. We will also have abundant fusion energy in the 2nd half of the century. So we have no long term energy problem. Solar/fusion energy will eventually be cheap and abundant, and at an equivalent of less than $30 per barrel of oil, we won’t bother using fossil fuels because they will be too expensive compared to alternatives. The problems we do have in energy supply are short term and mostly caused by idiotic green policies that worsen supply, costs and environmental impact. It is hard to think of a ‘green’ policy that actually works.

The CO2 problem will go away in the long term due to nothing but simple economics and market effects. In the short term, we don’t see a measurable problem due to a happy coincidence of solar cycles and ocean cycles counteracting the presumed warming forcing of the CO2. There is absolutely no need to rush into massively problematic taxes and subsidies for immature technology. The social problems caused by short term panic are far worse than the problem they are meant to fix. Increased food prices have been caused by regulation to enforce use of biofuels. Ludicrously stupid carbon offset programs have led to chopping down of rain forests, draining of peat bogs and forced relocation of local peoples, and after all tat have actually increased CO2 emissions. Lately, carbon taxes in the UK, far higher than elsewhere, have led to collapse of the aluminium and steel industries, while the products have still been produced elsewhere at higher CO2 cost. Those made redundant are made even poorer because they have to pay higher prices for energy thanks to enormous subsidies to rich people who own wind or solar farms. Finally, closing down fossil fuel plants before we have proper substitutes in place and then asking wind farm owners to accept even bigger subsidies to put in diesel generators for use on calm  and dull days is the politics of the asylum. Green policies perform best at transferring money from poor to rich, with environmental damage seemingly a small price to pay for a feel-good factor..

Call me a skeptic or a denier or whatever you want if you like. I am technically ‘luke warm’. There is a problem with CO2, but not a big one, and it will go away all by itself. There is no need for political interference and that which we have seen so far has made far worse problems for both people and the environment than climate change would ever have done. Our politicians would do a far better job if they did nothing at all.

So, Paris then. On one hand we have a minor problem from CO2 emissions that will go away fastest with the fewest problems if our politicians do nothing at all. On the other hand, their previous mistakes have already allowed the Islamist terrorist equivalent of 81 IRAs to enter Europe and the current migrant flux is increasing that by 3 IRAs per year. That does need to be addressed, quickly and effectively.

Perhaps they should all stay in Paris but change the subject.

 

The Future of Games (recycled from 2005)

I was trawling through some old documents and stumbled on this one from just over 10 years ago. The message still rings true, even if the recession has shifted the time frame somewhat compared to what I though then.

Games are getting serious

Ian Pearson, August 2005

Games are designed to be fun, but future games might be so much fun that they could start causing big social problems.

Forget the 15 inch monitor most people use today. What we are really talking about for tomorrow’s games is full immersion. Think Star Trek holodeck. Technology by 2020 will allow us to connect our nervous system to our computers, sampling nerve signals and recording every kind of sensation, replaying them in holiday memories, in communications, or in computer games. It will work using active skin, with electronics printed onto the skin, and tiny electronic components painlessly blown into the skin itself using compressed air jets. Some of these devices will link to nerve endings in our skin.

With touch, hearing and vision, computer games will be much more compelling. By 2020, another device that will be routine is the active contact lens, which uses tiny lasers and micro-mirrors to raster scan images straight onto your retina. This will give us a totally immersive 3D display.

Now imagine what people will do with this. With the massive processing and graphics capability of 2020 games machines, people could live all day in a pretty convincing full sensory virtual reality environment., and could live a fantasy life well beyond their real life means. Someone with a lousy real life, but enough pocket money to buy a games console, might effectively drop out of real life apart from eating, drinking, sleeping and going to the loo. And even in those activities, they can have a constant augmented reality overlay to make them more visually appealing.

But in their fantasy worlds, where they can kill everything or have sex with everyone they fancy, their brains might be corrupted to a point where they can no longer easily mix with civilised society. The real world will undoubtedly see more violence and more rape and sexual assaults.

But it doesn’t stop there. By 2030, robotics technology will be much more advanced. Some robots can already walk and dance. Polymer gel muscles and outer coatings will make many future robots look and feel like real people. The androids of science fiction are not long away now.

So how long will it be before the totally inoffensive (but exciting) Robot Wars is replaced by an android version of the Roman gladiator games? We would surely never stoop to using real people again, but why not androids? Even if they do have the latest AI modules with full emotions and self awareness? They are just machines, so who cares?  I really think that line of argument might well hold sway with many people. It is sad, but this century might well see the return of the lowest form of entertainment ever invented by man. Games are getting serious.

 

 

 

How to make a Star Wars light saber

A couple of years ago I explained how to make a free-floating combat drone: http://carbonweapons.com/2013/06/27/free-floating-combat-drones/ , like the ones in Halo or Mass Effect. They could realistically be made in the next couple of decades and are very likely to feature heavily in far future warfare, or indeed terrorism. I was chatting to a journalist this morning about light sabers, another sci-fi classic. They could also be made in the next few decades, using derivatives of the same principles. A prototype is feasible this side of 2050.

I’ll ignore the sci-fi wikis that explain how they are meant to work, which mostly approximate to fancy words for using magic or The Force and various fictional crystals. On the other hand, we still want something that will look and sound and behave like the light saber.

The handle bit is pretty obvious. It has to look good and contain a power source and either a powerful laser or plasma generator. The traditional problem with using a laser-based saber is that the saber is only meant to be a metre long but laser beams don’t generally stop until they hit something. Plasma on the other hand is difficult to contain and needs a lot of energy even when it isn’t being used to strike your opponent. A laser can be switched on and off and is therefore better. But we can have some nice glowy plasma too, just for fun.

The idea is pretty simple then. The blade would be made of graphene flakes coated with carbon nanotube electron pipes, suspended using the same technique I outlined in the blog above. These could easily be made to form a long cylinder and when you want the traditional Star Wars look, they would move about a bit, giving the nice shimmery blurry edge we all like so that the tube looks just right with blurry glowy edges. Anyway, with the electron pipe surface facing inwards, these flakes would generate the internal plasma and its nice glow. They would self-organize their cylinder continuously to follow the path of the saber. Easy-peasy. If they strike something, they would just re-organize themselves into the cylinder again once they are free.

For later models, a Katana shaped blade will obviously be preferred. As we know, all ultimate weapons end up looking like a Katana, so we might as well go straight to it, and have the traditional cylindrical light saber blade as an optional cosmetic envelope for show fights. The Katana is a universal physics result in all possible universes.

The hum could be generated by a speaker in the handle if you have absolutely no sense of style, but for everyone else, you could simply activate pulsed magnetic fields between the flakes so that they resonate at the required band to give your particular tone. Graphene flakes can be magnetized so again this is perfectly consistent with physics. You could download and customize hums from the cloud.

Now the fun bit. When the blade gets close to an object, such as your opponent’s arm, or your loaf of bread in need of being sliced, the capacitance of the outer flakes would change, and anyway, they could easily transmit infrared light in every direction and pick up reflections. It doesn’t really matter which method you pick to detect the right moment to activate the laser, the point is that this bit would be easy engineering and with lots of techniques to pick from, there could be a range of light sabers on offer. Importantly, at least a few techniques could work that don’t violate any physics. Next, some of those self-organizing graphene flakes would have reflective surface backings (metals bond well with graphene so this is also a doddle allowed by physics), and would therefore form a nice reflecting surface to deflect the laser beam at the object about to be struck. If a few flakes are vaporized, others would be right behind them to reflect the beam.

So just as the blade strikes the surface of the target, the powerful laser switches on and the beam is bounced off the reflecting flakes onto the target, vaporizing it and cauterizing the ends of the severed blood vessels to avoid unnecessary mess that might cause a risk of slipping. The shape of the beam depends on the locations and angles of the reflecting surface flakes, and they could be in pretty much any shape to create any shape of beam needed, which could be anything from a sharp knife to a single point, severing an arm or drilling a nice neat hole through the heart. Obviously, style dictates that the point of the saber is used for a narrow beam and the edge is used as a knife, also useful for cutting bread or making toast (the latter uses transverse laser deflection at lower aggregate power density to char rather than vaporize the bread particles, and toast is an option selectable by a dial on the handle).

What about fights? When two of these blades hit each other there would be a variety of possible effects. Again, it would come down to personal style. There is no need to have any feel at all, the beams could simple go through each other, but where’s the fun in that? Far better that the flakes also carry high electric currents so they could create a nice flurry of sparks and the magnetic interactions between the sabers could also be very powerful. Again, self organisation would allow circuits to form to carry the currents at the right locations to deflect or disrupt the opponent’s saber. A galactic treaty would be needed to ensure that everyone fights by the rules and doesn’t cheat by having an ethereal saber that just goes right through the other one without any nice show. War without glory is nothing, and there can be no glory without a strong emotional investment and physical struggle mediated by magnetic interactions in the sabers.

This saber would have a very nice glow in any color you like, but not have a solid blade, so would look and feel very like the Star Wars saber (when you just want to touch it, the lasers would not activate to slice your fingers off, provided you have read the safety instructions and have the safety lock engaged). The blade could also grow elegantly from the hilt when it is activated, over a second or so, it would not just suddenly appear at full length. We need an on/off button for that bit, but that could simply be emotion or thought recognition so it turns on when you concentrate on The Force, or just feel it.

The power supply could be a battery or graphene capacitor bank of a couple of containers of nice chemicals if you want to build it before we can harness The Force and magic crystals.

A light saber that looks, feels and behaves just like the ones on Star Wars is therefore entirely feasible, consistent with physics, and could be built before 2050. It might use different techniques than I have described, but if no better techniques are invented, we could still do it the way I describe above. One way or another, we will have light sabers.

 

Driverless pod transport system

I badly documented my latest idea of an ultra-cheap transport system in https://timeguide.wordpress.com/2015/10/24/an-ultra-cheap-future-transport-system/. I think I need another blog to separate out the idea from the background. Look at my previous blog for the appropriate pictures.

We’re seeing a lot of enthusiasm now for electric cars and in parallel, for self-driving cars. I support both of those, and I like the new Next system that is extremely close to my own ideas from 1987 when I first looked at cars from a performance engineer’s viewpoint and realized that self driving cars could drive millimeters apart, reducing drag and greatly reducing congestion. I estimated back then that they could improve road capacity by a factor of 5. Many others have since simulated such systems and the same factor of 5 has popped up a few times now.

Self-driving pods and electrically assisted bike lane

Slide4

Next have visualized the same idea nicely, but the world is more receptive now. http://www.techinsider.io/italys-next-created-self-driving-pods-that-can-connect-in-motion-to-form-a-train-2015-10

https://youtu.be/Wk12TmZ3GiQ for their nice video, although I’d envisage rather more pods in most areas, almost filling the entire road area.

I’ve lectured in vain many times to persuade authorities to divert investment away from 20th century rail system to roads using self driving cars. The UK’s HS2 system is no more than lipstick on a 20th century pig. Pig it remains, obsolete ages ago, though our idiotic government remains determined to build it anyway, wasting £70Bn even by charitable estimates. Systems similar to Next’s could replace HS2 and reduce journey times for everyone, not just those whose starting point and destination are very close to the terminals. I wish them well. But I think there is an even better solution, that is feasible in a similar time-frame, and I have no doubt they could pick it up and run with it. Or Tesla or Google or Apple or Toyota or any other car company.

My realization is that we don’t need self driving cars either. Take exactly the Next system, with its nicely trapezoidal pods that nest together. They will need a smooth road surface if they are to ride in contact or millimeters apart, or they will constantly bump into each other and create irritating vibration. Make them ride a centimeter or two apart and it will solve that.

Then start looking at each part of the system.

They each have a computer on board to drive the pod. You don’t need that, because everyone has a smart phone now which already has formidable computing power and is connected to the cloud, which has vast amounts more. Together, the entire system can be easily managed without any computers on board at all.

Similarly, much of the internal decor in cars is there to make it look pretty, offer interfaces, information or displays for passenger entertainment. All of that could easily be done by any half-decent augmented reality visor.

Then look at the power supply and engines. We should at the very least expect electric motors to replace fossil fuel engines. Most self-driving cars have expensive batteries, using scarce resources, and lithium batteries may catch fire or explode. So some systems in R&D now use the idea of super-capacitors instead. Furthermore, these could be recharged periodically as they drive over special mats on the road surface, so they could be smaller, lighter and cheaper. Even that is now being trialed. So these systems would already be better in almost every way to today’s transport.

However, we don’t even need the electric motors and super-capacitors. Instead we could update the ancient but well-proven idea of the linear induction motor and make factory-produced mats containing circuits that can be instructed to make steerable magnetic wells that pull the cars along, as well as navigate them correctly at every junction. Again, the management can all be done by the cloud plus smartphones, and the circuits can reconfigure on command as each pod passes over them. So they won’t need batteries, or super-capacitor banks, or engines or motors. They would just be pulled along by magnetic fields, with no moving parts (apart from the pods as a whole of course) to go wrong, and almost nothing needing expensive maintenance. Apart from wheels, suspension and brakes.

So the driverless pod would not need a built-in computer, it would not need an engine or motor, and not need a battery or super-capacitor. Already it would be vastly cheaper.

The last remaining moving parts can also be dispensed with. If the pod rides above a mat that can generate the magnetic fields to drag it along, why not let other magnetic fields suspend it above the ground? That would mean it doesn’t need suspension, or wheels. Conventional brakes could be dispensed with using a combination of magnetic fields for normal braking,  combined with a fallback of gravity and brake strips for emergency braking. Reducing the levitation field would create friction with the road surface and stop the vehicle very quickly, far more quickly than a conventional car can stop, only really limited by comfort limitations.

So my proposal is a system that would look and behave very similar to what Next have designed, but would not need engines, batteries, on-board computers or even wheels. My pods would be no more than simple boxes with comfy seats (or empty for freight transport) and a couple of strips on the bottom and might cost no more than $200 each. The road would have a factory-made mat laid on top for the magnetic well trains and levitation. Adapting a road to the system would be an overnight laying out of the mat and plugging it in to the electricity supply. In cold seasons, that electricity supply could also power on-board heating (but that would incur extra expense of course)

Slide3

transport system

It won’t be long before such a system could be built. I can’t see any fundamental barriers to a prototype appearing next year if some entrepreneur were to try. It could make self driving car systems, even Next’s current proposals, redundant before they are implemented. If we were to change the direction of current plans to utilize the latest technology, rather than using ideas from 30 years ago, we could have a cheaper, better, more environmentally friendly system even faster. We could probably build such as system in every major city for what we are going to waste on HS2. Surely that is worth a try.

 

The future of nylon: ladder-free hosiery

Last week I outlined the design for a 3D printer that can print and project graphene filaments at 100m/s. That was designed to be worn on the wrist like Spiderman’s, but an industrial version could print faster. When I checked a few of the figures, I discovered that the spinnerets for making nylon stockings run at around the same speed. That means that graphene stockings could be made at around the same speed. My print head produced 140 denier graphene yarn but it made that from many finer filaments so basically any yarn thickness from a dozen carbon atoms right up to 140 denier would be feasible.

The huge difference is that a 140 denier graphene thread is strong enough to support a man at 2g acceleration. 10 denier stockings are made from yarn that breaks quite easily, but unless I’ve gone badly wrong on the back of my envelope, 10 denier graphene would have roughly 10kg (22lb)breaking strain. That’s 150 times stronger than nylon yarn of the same thickness.

If so, then that would mean that a graphene stocking would have incredible strength. A pair of 10 denier graphene stockings or tights (pantyhose) might last for years without laddering. That might not be good news for the nylon stocking industry, but I feel confident they would adapt easily to such potential.

Alternatively, much finer yarns could be made that would still have reasonable ladder resistance, so that would also affect the visual appearance and texture. They could be made so fine that the fibers are invisible even up close. People might not always want that, but the key message is that wear-resistant, ladder free hosiery could be made that has any gauge from 0.1 denier to 140 denier.

There is also a bonus that graphene is a superb conductor. That means that graphene fibers could be woven into nylon hosiery to add circuits. Those circuits might be to harvest radio energy, act as an aerial, power LEDS in the hosiery or change its colors or patterns. So even if it isn’t used for the whole garment, it might still have important uses in the garment as an addition to the weave.

There is yet another bonus. Graphene circuits could allow electrical supply to shape changing polymers that act rather like muscles, contracting when a voltage is applied across them, so that a future pair of tights could shape a leg far better, with tensions and pressures electronically adjusted over the leg to create the perfect shape. Graphene can make electronic muscles directly too, but in a more complex mechanism (e.g. using magnetic field generation and interaction, or capacitors and electrical attraction/repulsion).

The future for IT technicians

This blog accompanies the British Computer Society’s launch of RITTech, a new standard for IT technicians. For more info look at:

http://www.bcs.org/content/conWebDoc/55343 and

http://www.bcs.org/category/18031

It is a great time to be in IT. Companies are fragmenting and reconstructing and new business models are emerging every year. Everything is becoming smart, bringing IT to pole position in the sector race. Everyone has multiple mobile devices – smart phones, tablets, readers and laptops, even smart watches and wristbands. The opportunities to add electronic control are abundant, but they all need to be developed, software written and circuits fabricated and tested. Engineers have never had more core technologies to play with to create new products and services, and they rely on technicians to make it happen.

One of the most important things for anyone in a globalised world, where potential customers or employers will often never have met you or even seen you, is to be certificated. Having a respected industry body confirm that you have reached a given level of ability makes decisions  safer. Knowing that a person has the skills required to do the job takes away the biggest risk in employing them for a project. Global companies such as Microsoft offer such certification, but so can professional bodies such as the British Computer Society. The important factor is that the body is known, respected and their certification trusted.

Trust is absolutely key in a networked world. Anyone can pretend to be anyone, and can act across borders via the net from anywhere. Dangers lurk everywhere. People need to know they can trust appliances they use, the websites they visit. They need to be confident that their details will not end up in the hands of criminals, especially anything related to their finances. They also need to be confident that code won’t crash their machines or leave them open to hackers. Few people have the ability to look after all the IT themselves, so they rely on others to make it safe for them. They trust a corporate brand, so they trust their website, so that means that company has to be able to trust those who write it and maintain it to be able to do their work competently and reliably.

That is all getting more and more difficult in a miniaturizing world. The internet of things is already bringing us into the early stages of digital jewellery. From there, it is only a small step further before IT devices will often be dust sized, well below a millimetre, and then they could easily fit through the holes in an office machine, or sit on keys on a keyboard. Add that to security holes in a smart light bulb that nobody thought of as a security risk, but which opens a back door into a home LAN, and it becomes obvious just how tricky it will be to make things secure.

Security will remain a background problem no matter what is being built, but that doesn’t take away the excitement of making something new. Every wave of new core technology opens up new doors to new gadgets or network capability. Artificial intelligence also adds capability in parallel. A huge gap has opened over recent years between what has become possible and what has been done. There just aren’t enough engineers and technicians to do everything. That means it has never been easier to invent things, to find something exciting that nobody has done yet. That next big thing could be invented by you.

You might think it won’t be because your boss has you working on another project, but new tech opens up potential in every area. There is probably something right next to your project waiting to be discovered or developed. Showing creativity or innovative capability will fast track you to your next promotion and when your colleagues learn you have done something special, you will feel the warm glow of recognition too. Few things feel better than peer recognition. Nobody is too junior to come up with a new idea, or a new way of looking at something, or spotting a feature that would increase customer satisfaction without increasing cost. Some of my best ideas have happened in areas I have just started work in. If you’re new, you might not have all the finely honed skills of someone who’s been working in it for years, but you also don’t have their prejudices, you don’t know why you can’t do something, so you just do it anyway. The barriers they thought they knew about may have been rendered irrelevant by technology progress but their prejudice hasn’t kept up with change. You might be surprised how often that is the case.

In short, as a technician going for certification, you are laying down a solid foundation for secure and fruitful employment in exciting fields. That same desire to take control, push yourself to your limits and make life work for you will also make you exactly the sort of person that is likely to do something  special. A technician is an important person already, making dreams happen, but ahead lies a career full of opportunity for further development, excitement and fulfilment.

How to make a Spiderman-style graphene silk thrower for emergency services

I quite like Spiderman movies, and having the ability to fire a web at a distant object or villain has its appeal. Since he fires web from his forearm, it must be lightweight to withstand the recoil, and to fire enough to hold his weight while he swings, it would need to have extremely strong fibers. It is therefore pretty obvious that the material of choice when we build such a thing will be graphene, which is even stronger than spider silk (though I suppose a chemical ejection device making spider silk might work too). A thin graphene thread is sufficient to hold him as he swings so it could fit inside a manageable capsule.

So how to eject it?

One way I suggested for making graphene threads is to 3D print the graphene, using print nozzles made of carbon nanotubes and using a very high-speed modulation to spread the atoms at precise spacing so they emerge in the right physical patterns and attach appropriate positive or negative charge to each atom as they emerge from the nozzles so that they are thrown together to make them bond into graphene. This illustration tries to show the idea looking at the nozzles end on, but shows only a part of the array:printing graphene filamentsIt doesn’t show properly that the nozzles are at angles to each other and the atoms are ejected in precise phased patterns, but they need to be, since the atoms are too far apart to form graphene otherwise so they need to eject at the right speed in the right directions with the right charges at the right times and if all that is done correctly then a graphene filament would result. The nozzle arrangements, geometry and carbon atom sizes dictate that only narrow filaments of graphene can be produced by each nozzle, but as the threads from many nozzles are intertwined as they emerge from the spinneret, so a graphene thread would be produced made from many filaments. Nevertheless, it is possible to arrange carbon nanotubes in such a way and at the right angle, so provided we can get the high-speed modulation and spacing right, it ought to be feasible. Not easy, but possible. Then again, Spiderman isn’t real yet either.

The ejection device would therefore be a specially fabricated 3D print head maybe a square centimeter in area, backed by a capsule containing finely powdered graphite that could be vaporized to make the carbon atom stream through the nozzles. Some nice lasers might be good there, and some cool looking electronic add-ons to do the phasing and charging. You could make this into one heck of a cool gun.

How thick a thread do we need?

Assuming a 70kg (154lb) man and 2g acceleration during the swing, we need at least 150kg breaking strain to have a small safety margin, bearing in mind that if it breaks, you can fire a new thread. Steel can achieve that with 1.5mm thick wire, but graphene’s tensile strength is 300 times better than steel so 0.06mm is thick enough. 60 microns, or to put it another way, roughly 140 denier, although that is a very quick guess. That means roughly the same sort of graphene thread thickness is needed to support our Spiderman as the nylon used to make your backpack. It also means you could eject well over 10km of thread from a 200g capsule, plenty. Happy to revise my numbers if you have better ones. Google can be a pain!

How fast could the thread be ejected?

Let’s face it. If it can only manage 5cm/s, it is as much use as a chocolate flamethrower. Each bond in graphene is 1.4 angstroms long, so a graphene hexagon is about 0.2nm wide. We would want our graphene filament to eject at around 100m/s, about the speed of a crossbow bolt. 100m/s = 5 x 10^11 carbon atoms ejected per second from each nozzle, in staggered phasing. So, half a terahertz. Easy! That’s well within everyday electronics domains. Phew! If we can do better, we can shoot even faster.

We could therefore soon have a graphene filament ejection device that behaves much like Spiderman’s silk throwers. It needs some better engineers than me to build it, but there are plenty of them around.

Having such a device would be fun for sports, allowing climbers to climb vertical rock faces and overhangs quickly, or to make daring leaps and hope the device works to save them from certain death. It would also have military and police uses. It might even have uses in road accident prevention, yanking pedestrians away from danger or tethering cars instantly to slow them extra quickly. In fact, all the emergency services would have uses for such devices and it could reduce accidents and deaths. I feel confident that Spiderman would think of many more exciting uses too.

Producing graphene silk at 100m/s might also be pretty useful in just about every other manufacturing industry. With ultra-fine yarns with high strength produced at those speeds, it could revolutionize the fashion industry too.
