Chat-bots will help reduce loneliness, a bit

Amazon is really pushing its Echo and Dot devices at the moment and some other companies also use Alexa in their own devices. They are starting to gain avatar front ends too. Microsoft has their Cortana transforming into Zo, Apple has Siri’s future under wraps for now. Maybe we’ll see Siri in a Sari soon, who knows. Thanks to rapidly developing AI, chatbots and other bots have also made big strides in recent years, so it’s obvious that the two can easily be combined. The new voice control interfaces could become chatbots to offer a degree of companionship. Obviously that isn’t as good as chatting to real people, but many, very many people don’t have that choice. Loneliness is one of the biggest problems of our time. Sometimes people talk to themselves or to their pet cat, and chatting to a bot would at least get a real response some of the time. It goes further than simple interaction though.

I’m not trying to understate the magnitude of the loneliness problem, and it can’t solve it completely of course, but I think it will be a benefit to at least some lonely people in a few ways. Simply having someone to chat to will already be of some help. People will form emotional relationships with bots that they talk to a lot, especially once they have a visual front end such as an avatar. It will help some to develop and practice social skills if that is their problem, and for many others who feel left out of local activity, it might offer them real-time advice on what is on locally in the next few days that might appeal to them, based on their conversations. Talking through problems with a bot can also help almost as much as doing so with a human. In ancient times when I was a programmer, I’d often solve a bug by trying to explain how my program worked, and in doing so i would see the bug myself. Explaining it to a teddy bear would have been just as effective, the chat was just a vehicle for checking through the logic from a new angle. The same might apply to interactive conversation with a bot. Sometimes lonely people can talk too much about problems when they finally meet people, and that can act as a deterrent to future encounters, so that barrier would also be reduced. All in all, having a bot might make lonely people more able to get and sustain good quality social interactions with real people, and make friends.

Another benefit that has nothing to do with loneliness is that giving a computer voice instructions forces people to think clearly and phrase their requests correctly, just like writing a short computer program. In a society where so many people don’t seem to think very clearly or even if they can, often can’t express what they want clearly, this will give some much needed training.

Chatbots could also offer challenges to people’s thinking, even to help counter extremism. If people make comments that go against acceptable social attitudes or against known facts, a bot could present the alternative viewpoint, probably more patiently than another human who finds such viewpoints frustrating. I’d hate to see this as a means to police political correctness, though it might well be used in such a way by some providers, but it could improve people’s lack of understanding of even the most basic science, technology, culture or even politics, so has educational value. Even if it doesn’t convert people, it might at least help them to understand their own views more clearly and be better practiced at communicating their arguments.

Chat bots could make a significant contribution to society. They are just machines, but those machines are tools for other people and society as a whole to help more effectively.


Colour changing cars, everyday objects and makeup shows how graphene can be used to make displays with each pixel changing colour according to mechanical deformation.

Meanwhile, Lexus have just created a car with a shell covered in LEDs so it can act as a massive display.

In 2014 I wrote about using polymer LED displays for future Minis so it’s nice to see another prediction come true.

Looking at the mechanical pixels though, it is clear that mechanical pixels could respond directly to sound, or to turbulence of passing air, plus other vibration that arises from motion on a road surface, or the engine. Car panel colours could change all the time powered by ambient energy. Coatings on any solid objects could follow, so people might have plenty of shimmering colours in their everyday environment. Could. Not sure I want it, but they could.

With sound as a control system, sound wave generators at the edges or underneath such surfaces could produce a wide variety of pleasing patterns. We could soon have furniture that does a good impression of being a cuttlefish.

I often get asked about smart makeup, on which I’ve often spoken since the late 90s. Thin film makeup displays could use this same tech. So er, we could have people with makeup pretending to be cuttlefish too. I think I’ll quit while I’m ahead.

Carbethium, a better-than-scifi material

How to build one of these for real:


Halo light bridge, from

Or indeed one of these:



I recently tweeted that I had an idea how to make the glowy bridges and shields we’ve seen routinely in sci-fi games from Half Life to Destiny, the bridges that seem to appear in a second or two from nothing across a divide, yet are strong enough to drive tanks over, and able to vanish as quickly and completely when they are switched off. I woke today realizing that with a bit of work, that it could be the basis of a general purpose material to make the tanks too, and buildings and construction platforms, bridges, roads and driverless pod systems, personal shields and city defense domes, force fields, drones, planes and gliders, space elevator bases, clothes, sports tracks, robotics, and of course assorted weapons and weapon systems. The material would only appear as needed and could be fully programmable. It could even be used to render buildings from VR to real life in seconds, enabling at least some holodeck functionality. All of this is feasible by 2050.

Since it would be as ethereal as those Halo structures, I first wanted to call the material ethereum, but that name was already taken (for a 2014 block-chain programming platform, which I note could be used to build the smart ANTS network management system that Chris Winter and I developed in BT in 1993), and this new material would be a programmable construction platform so the names would conflict, and etherium is too close. Ethium might work, but it would be based on graphene and carbon nanotubes, and I am quite into carbon so I chose carbethium.

Ages ago I blogged about plasma as a 21st Century building material. I’m still not certain this is feasible, but it may be, and it doesn’t matter for the purposes of this blog anyway.

Around then I also blogged how to make free-floating battle drones and more recently how to make a Star Wars light-saber.

Carbethium would use some of the same principles but would add the enormous strength and high conductivity of graphene to provide the physical properties to make a proper construction material. The programmable matter bits and the instant build would use a combination of 3D interlocking plates, linear induction,  and magnetic wells. A plane such as a light bridge or a light shield would extend from a node in caterpillar track form with plates added as needed until the structure is complete. By reversing the build process, it could withdraw into the node. Bridges that only exist when they are needed would be good fun and we could have them by 2050 as well as the light shields and the light swords, and light tanks.

The last bit worries me. The ethics of carbethium are the typical mixture of enormous potential good and huge potential for abuse to bring death and destruction that we’re learning to expect of the future.

If we can make free-floating battle drones, tanks, robots, planes and rail-gun plasma weapons all appear within seconds, if we can build military bases and erect shield domes around them within seconds, then warfare moves into a new realm. Those countries that develop this stuff first will have a huge advantage, with the ability to send autonomous robotic armies to defeat enemies with little or no risk to their own people. If developed by a James Bond super-villain on a hidden island, it would even be the sort of thing that would enable a serious bid to take over the world.

But in the words of Professor Emmett Brown, “well, I figured, what the hell?”. 2050 values are not 2016 values. Our value set is already on a random walk, disconnected from any anchor, its future direction indicated by a combination of current momentum and a chaos engine linking to random utterances of arbitrary celebrities on social media. 2050 morality on many issues will be the inverse of today’s, just as today’s is on many issues the inverse of the 1970s’. Whatever you do or however politically correct you might think you are today, you will be an outcast before you get old:

We’re already fucked, carbethium just adds some style.

Graphene combines huge tensile strength with enormous electrical conductivity. A plate can be added to the edge of an existing plate and interlocked, I imagine in a hexagonal or triangular mesh. Plates can be designed in many diverse ways to interlock, so that rotating one engages with the next, and reversing the rotation unlocks them. Plates can be pushed to the forward edge by magnetic wells, using linear induction motors, using the graphene itself as the conductor to generate the magnetic field and the design of the structure of the graphene threads enabling the linear induction fields. That would likely require that the structure forms first out of graphene threads, then the gaps between filled by mesh, and plates added to that to make the structure finally solid. This would happen in thickness as well as width, to make a 3D structure, though a graphene bridge would only need to be dozens of atoms thick.

So a bridge made of graphene could start with a single thread, which could be shot across a gap at hundreds of meters per second. I explained how to make a Spiderman-style silk thrower to do just that in a previous blog:

The mesh and 3D build would all follow from that. In theory that could all happen in seconds, the supply of plates and the available power being the primary limiting factors.

Similarly, a shield or indeed any kind of plate could be made by extending carbon mesh out from the edge or center and infilling. We see that kind of technique used often in sci-fi to generate armor, from lost in Space to Iron Man.

The key components in carbetheum are 3D interlocking plate design and magnetic field design for the linear induction motors. Interlocking via rotation is fairly easy in 2D, any spiral will work, and the 3rd dimension is open to any building block manufacturer. 3D interlocking structures are very diverse and often innovative, and some would be more suited to particular applications than others. As for linear induction motors, a circuit is needed to produce the travelling magnetic well, but that circuit is made of the actual construction material. The front edge link between two wires creates a forward-facing magnetic field to propel the next plates and convey enough intertia to them to enable kinetic interlocks.

So it is feasible, and only needs some engineering. The main barrier is price and material quality. Graphene is still expensive to make, as are carbon nanotubes, so we won’t see bridges made of them just yet. The material quality so far is fine for small scale devices, but not yet for major civil engineering.

However, the field is developing extremely quickly because big companies and investors can clearly see the megabucks at the end of the rainbow. We will have almost certainly have large quantity production of high quality graphene for civil engineering by 2050.

This field will be fun. Anyone who plays computer games is already familiar with the idea. Light bridges and shields, or light swords would appear much as in games, but the material would likely  be graphene and nanotubes (or maybe the newfangled molybdenum equivalents). They would glow during construction with the plasma generated by the intense electric and magnetic fields, and the glow would be needed afterward to make these ultra-thin physical barriers clearly visible,but they might become highly transparent otherwise.

Assembling structures as they are needed and disassembling them just as easily will be very resource-friendly, though it is unlikely that carbon will be in short supply. We can just use some oil or coal to get more if needed, or process some CO2. The walls of a building could be grown from the ground up at hundreds of meters per second in theory, with floors growing almost as fast, though there should be little need to do so in practice, apart from pushing space vehicles up so high that they need little fuel to enter orbit. Nevertheless, growing a  building and then even growing the internal structures and even furniture is feasible, all using glowy carbetheum. Electronic soft fabrics, cushions and hard surfaces and support structures are all possible by combining carbon nanotubes and graphene and using the reconfigurable matter properties carbethium convents. So are visual interfaces, electronic windows, electronic wallpaper, electronic carpet, computers, storage, heating, lighting, energy storage and even solar power panels. So is all the comms and IoT and all the smart embdedded control systems you could ever want. So you’d use a computer with VR interface to design whatever kind of building and interior furniture decor you want, and then when you hit the big red button, it would appear in front of your eyes from the carbethium blocks you had delivered. You could also build robots using the same self-assembly approach.

If these structures can assemble fast enough, and I think they could, then a new form of kinetic architecture would appear. This would use the momentum of the construction material to drive the front edges of the surfaces, kinetic assembly allowing otherwise impossible and elaborate arches to be made.

A city transport infrastructure could be built entirely out of carbethium. The linear induction mats could grow along a road, connecting quickly to make a whole city grid. Circuit design allows the infrastructure to steer driverless pods wherever they need to go, and they could also be assembled as required using carbethium. No parking or storage is needed, as the pod would just melt away onto the surface when it isn’t needed.

I could go to town on military and terrorist applications, but more interesting is the use of the defense domes. When I was a kid, I imagined having a house with a defense dome over it. Lots of sci-fi has them now too. Domes have a strong appeal, even though they could also be used as prisons of course. A supply of carbetheum on the city edges could be used to grow a strong dome in minutes or even seconds, and there is no practical limit to how strong it could be. Even if lasers were used to penetrate it, the holes could fill in in real time, replacing material as fast as it is evaporated away.

Anyway, lots of fun. Today’s civil engineering projects like HS2 look more and more primitive by the day, as we finally start to see the true potential of genuinely 21st century construction materials. 2050 is not too early to expect widespread use of carbetheum. It won’t be called that – whoever commercializes it first will name it, or Google or MIT will claim to have just invented it in a decade or so, so my own name for it will be lost to personal history. But remember, you saw it here first.

The future of vacuum cleaners

Dyson seems pretty good in vacuum cleaners and may well have tried this and found it doesn’t work, but then again, sometimes people in an industry can’t see the woods for the trees so who knows, there may be something in this:

Our new pet cat Jess, loves to pick up soft balls with a claw and throw them, and catch them again. Retractable claws are very effective.IMG_6689- Jess (2)

Jess the cat

At a smaller scale, velcro uses tiny little hooks to stick together, copying burs from nature.

Suppose you make a tiny little ball that has even tinier little retractable spines or even better, hooks. And suppose you make them by the trillion and make a powder that your vacuum cleaner attachment first sprinkles onto a carpet, then agitates furiously and quickly, and thus gets the hooks to stick to dirt, pull it off the surface and retract (so that the balls don’t stick to the carpet) and then you suck the whole lot into the machine. Since the balls have a certain defined specification, they are easy to separate from the dirt and dust and reuse again straight away. So you get superior cleaning. Some of the balls would be lost each time, and some would get sucked up next time, but overall you’d need to periodically top up the reservoir.

The current approach is to beat the hell out of the carpet fibers with a spinning brush and that works fine, but I think adding the active powder might be better because it gets right in among the dirt and drags it kicking and screaming off the fibers.

So, ball design. Firstly, it doesn’t need to be ball shaped at all, and secondly it doesn’t need spines really, just to be able to rapidly change its shape so it gets some sort of temporary traction on a dirt particle to knock it off. What we need here is any structure that expands and contracts or dramatically changes shape when a force is applied, ideally resonantly. Two or three particles connected by a tether would move back and forwards under an oscillating electrostatic, electrical or magnetic field or even an acoustic wave. There are billions of ways of doing that and some would be cheaper than others to manufacture in large quantity. Chemists are brilliant at designing custom molecules with particular shapes, and biology has done that with zillions of enzymes too. Our balls would be pretty small but more micro-tech than nano-tech or molecular tech.

The vacuum cleaner attachment would thus spray this stuff onto the carpet and start resonating it with an EM field or sound waves. The little particles would wildly thrash around doing their micro-cleaning, yanking dirt free, and then they would be sucked back into the cleaner to be used again. The cleaner head doesn’t even need to have a spinning brush, the only moving parts would be the powder, though having an agitating brush might help get them deeper into the fabric I guess.


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).

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.

The future of make-up

I was digging through some old 2002 powerpoint slides for an article on active skin and stumbled across probably the worst illustration I have ever done, though in my defense, I was documenting a great many ideas that day and spent only a few minutes on it:

smart makeup

If a woman ever looks like this, and isn’t impersonating a bald Frenchman, she has more problems to worry about than her make-up. The pic does however manage to convey the basic principle, and that’s all that is needed for a technical description. The idea is that her face can be electronically demarked into various makeup regions and the makeup on those regions can therefore adopt the appropriate colour for that region. In the pic ‘nanosomes’ wasn’t a serious name, but a sarcastic take on the cosmetics industry which loves to take scientific sounding words and invent new ones that make their products sound much more high tech than they actually are. Nanotech could certainly play a role, but since the eye can’t discern features smaller than 0.1mm, it isn’t essential. This is no longer just an idea, companies are now working on development of smart makeup, and we already have prototype electronic tattoos, one of the layers I used for my active skin but again based on an earlier vision.

The original idea didn’t use electronics, but simply used self-organisation tech I’d designed in 1993 on an electronic DNA project. Either way would work, but the makeup would be different for each.

The electronic layer, if required, would most likely be printed onto the skin at a beauty salon, would be totally painless, last weeks and could take only a few minutes to print. It extends IoT to the face.

Both mechanisms could use makeup containing flat plates that create colour by diffraction the same way the scales on a butterfly does. That would make an excellent colour pallet. Beetles produce colour a different way and that would work too. Or we could copy squids or cuttlefish. Nature has given us many excellent start points for biomimetics, and indeed the self-organisation principles were stolen from nature too. Nature used hormone gradients to help your cells differentiate when you were an embryo. If nature can arrange the rich microscopic detail of every part of your face, then similar techniques can certainly work for a simple surface layer of make-up. Having the electronic underlay makes self organisation easier but it isn’t essential. There are many ways to implement self organisation in makeup and only some of them require any electronics at all, and some of those would use electronic particles embedded in the make-up rather than an underlay.

An electronic underlay can be useful to provide the energy for a transition too, and that allows the makeup to change colour on command. That means in principle that a woman could slap the makeup all over her face and touch a button on her digital mirror (which might simply be a tablet or smart phone) and the make-up would instantly change to be like the picture she selected. With suitable power availability, the make-up could be a full refresh rate video display, and we might see teenagers walking future streets wearing kaleidoscopic make-up that shows garish cartoon video expressions and animates their emoticons. More mature women might choose different appearances for different situations and they could be selected manually via an app or gesture or automatically by predetermined location settings.

Obviously, make-up is mostly used on the face, but once it becomes the basis of a smear-on computer display, it could be used on any part of the body as a full touch sensitive display area, e.g. the forearm.

Although some men already wear makeup, many more might use smart make-up as its techie nature makes it more acceptable.

The future of washing machines

Ultrasonic washing ball

Ultrasonic washing ball

For millennia, people washed clothes by stirring, hitting, squeezing and generally agitating them in rivers or buckets of water. The basic mechanism is to loosen dirt particles and use the water to wash them away or dissolve them.

Mostly, washing machines just automate the same process, agitating clothes in water, sometimes with detergent, to remove dirt from the fabric. Most use detergent to help free the dirt particles but more recently, some use ultrasound to create micro-cavitation bubbles and when they collapse, the shock waves help release the particles. That means the machines can clean at lower temperatures with little or no detergent.

It occurred to me that we don’t really need the machine to tumble the clothes. A ball about the size of a grapefruit could contain batteries and a set of ultrasonic transducers and could be simply chucked in a bucket with the clothes. It could create the bubbles and clean the clothes. Some basic engineering has to be done to make it work but it is entirely feasible.

One of the problems is that ultrasound doesn’t penetrate very far. To solve that, two mechanisms can be used in parallel. One is to let the ball roam around the clothes, and that could be done by changing its density by means of a swim bladder and using gravity to move it up and down, or maybe by adding a few simple paddles or cilia so it can move like a bacterium or by changing its shape so that as it moves up and down, it also moves sideways. The second mechanism is to use phased array ultrasonic transducers so that the beams can be steered and interfere constructively, thereby focusing energy and micro-cavitation generation around the bucket in a chosen pattern.

Making such a ball could be much cheaper than a full sized washing machine, making it ideal for developing countries. Transducers are cheap, and the software to drive them and steer the beams is easy enough and replicable free of charge once developed.

It would contain a rechargeable battery that could use a simple solar panel charging unit (which obviously could be used to generate power for other purposes too).

Such a device could bring cheap washing machine capability to millions of people who can’t afford a full sized washing machine or who are not connected to electricity supplies. It would save time, water and a great deal of drudgery at low expense.



Stimulative technology

You are sick of reading about disruptive technology, well, I am anyway. When a technology changes many areas of life and business dramatically it is often labelled disruptive technology. Disruption was the business strategy buzzword of the last decade. Great news though: the primarily disruptive phase of IT is rapidly being replaced by a more stimulative phase, where it still changes things but in a more creative way. Disruption hasn’t stopped, it’s just not going to be the headline effect. Stimulation will replace it. It isn’t just IT that is changing either, but materials and biotech too.

Stimulative technology creates new areas of business, new industries, new areas of lifestyle. It isn’t new per se. The invention of the wheel is an excellent example. It destroyed a cave industry based on log rolling, and doubtless a few cavemen had to retrain from their carrying or log-rolling careers.

I won’t waffle on for ages here, I don’t need to. The internet of things, digital jewelry, active skin, AI, neural chips, storage and processing that is physically tiny but with huge capacity, dirt cheap displays, lighting, local 3D mapping and location, 3D printing, far-reach inductive powering, virtual and augmented reality, smart drugs and delivery systems, drones, new super-materials such as graphene and molybdenene, spray-on solar … The list carries on and on. These are all developing very, very quickly now, and are all capable of stimulating entire new industries and revolutionizing lifestyle and the way we do business. They will certainly disrupt, but they will stimulate even more. Some jobs will be wiped out, but more will be created. Pretty much everything will be affected hugely, but mostly beneficially and creatively. The economy will grow faster, there will be many beneficial effects across the board, including the arts and social development as well as manufacturing industry, other commerce and politics. Overall, we will live better lives as a result.

So, you read it here first. Stimulative technology is the next disruptive technology.


The future of drones – predators. No, not that one.

It is a sad fact of life that companies keep using the most useful terminology for things that don’t deserve it. The Apple retina display, which makes it more difficult to find a suitable name for direct retinal displays that use the retina directly. Why can’t they be the ones called retina displays? Or the LED TV, where the LEDs are typically just LED back-lighting for an LCD display. That makes it hard to name TVs where each pixel is actually an LED. Or the Predator drone, as definitely  not the topic of this blog, where I will talk about predator drones that attack other ones.

I have written several times now on the dangers of drones. My most recent scare was realizing the potential for small drones carrying high-powered lasers and using cloud based face recognition to identify valuable targets in a crowd and blind them, using something like a Raspberry Pi as the main controller. All of that could be done tomorrow with components easily purchased on the net. A while ago I blogged that the Predators and Reapers are not the ones you need to worry about, so much as the little ones which can attack you in swarms.

This morning I was again considering terrorist uses for the micro-drones we’re now seeing. A 5cm drone with a networked camera and control could carry a needle infected with Ebola or aids or carrying a drop of nerve toxin. A small swarm of tiny drones, each with a gram of explosive that detonates when it collides with a forehead, could kill as many people as a bomb.

We will soon have to defend against terrorist drones and the tiniest drones give the most effective terror per dollar so they are the most likely to be the threat. The solution is quite simple. and nature solved it a long time ago. Mosquitos and flies in my back garden get eaten by a range of predators. Frogs might get them if they come too close to the surface, but in the air, dragonflies are expert at catching them. Bats are good too. So to deal with threats from tiny drones, we could use predator drones to seek and destroy them. For bigger drones, we’d need bigger predators and for very big ones, conventional anti-aircraft weapons become useful. In most cases, catching them in nets would work well. Nets are very effective against rotors. The use of nets doesn’t need such sophisticated control systems and if the net can be held a reasonable distance from the predator, it won’t destroy it if the micro-drone explodes. With a little more precise control, spraying solidifying foam onto the target drone could also immobilize it and some foams could help disperse small explosions or contain their lethal payloads. Spiders also provide inspiration here, as many species wrap their victims in silk to immobilize them. A single predator could catch and immobilize many victims. Such a defense system ought to be feasible.

The main problem remains. What do we call predator drones now that the most useful name has been trademarked for a particular model?
