This offer is now over. Sorry if you missed it.
As an early Christmas present, I have made all of my books free just for today on Amazon. The links here are for amazon.co.uk, but the book reference is the same on other branches so just edit the .co.uk to .com or whatever.
You Tomorrow and Society Tomorrow were almost entirely made by adding some of my blogs, tidying up and filling a few gaps.
Total Sustainability takes a system level view of sustainability and contradicts a lot of environmentalist dogma.
Space Anchor is my only Sci-fi novel to date, and features the first ever furry space ship in sci-fi, a gender-fluid AI, and its heroes Carbon Girl and Carbon Man have an almost entirely carbon-based itinerary.
Enjoy reading. Next year I hope to finish my book on future fashion.
A few 3D mist displays have been demonstrated over the last decade. I’ve seen a couple at trade shows and have been impressed. To date, they use mists or curtains of tiny water droplets to make a 3D space onto which to project an image, so you get a walk-through 3D life-sized display. Like this:

Two years ago, I suggested using a forehead-mounted mist projector:
so you could have a 3D image made right in front of you anywhere.
This week, a holographic display has been doing the rounds on Twitter, called Gatebox:
It looks OK but mist displays might be better solution for everyday use because they can be made a lot bigger more cheaply. However, nobody really wants water mist causing electrical problems in their PCs or making their notebook paper soggy. You can use smoke as a mist substitute but then you have a cloud of smoke around you. So…
Suppose instead of using water droplets and walking around veiled in fog or smoke or accompanied by electrical crackling and dead PCs, that the mist was not made of water droplets but tiny dry and obviously non-toxic particles such as fluorescent micro-spheres that are invisible to the naked eye and transparent to visible light so you can’t see the mist at all, and it won’t make stuff damp. Instead of projecting visible light, the particles are made of fluorescent material, so that they are illuminated by a UV projector and fluoresce with the right colour to make the visible display. There are plenty of fluorescent materials that could be made into tiny particles, even nano-particles, and made into an invisible mist that produces a bright and high-resolution display. Even if non-toxic is too big an ask, or the fluorescent material is too expensive to waste, a large box that keeps them contained and recycles them for the next display could still be bigger, better, brighter and cheaper than a large holographic display.
Remember, you saw it here first. My 101st invention of 2016.

http://www.theverge.com/2016/11/24/13740946/dutch-scientists-use-color-changing-graphene-bubbles-to-create-mechanical-pixels 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.
High altitude solar array to power IT and propel planes
A zero carbon air travel solution. Well, most of the bits would be made of carbon materials, but it wouldn’t emit any CO2.
The pic says it all. A linear solar farm suspended in the high atmosphere to provide an IT platform for sensors, comms and other functions often accomplished by low orbit satellite. It would float up there thanks to being fixed to a graphene foam base layer that can be made lighter than helium (my previous invention, see https://timeguide.wordpress.com/2013/01/05/could-graphene-foam-be-a-future-helium-substitute/ which has since been prototyped and proven to be extremely resilient to high pressures too). Ideally, it would go all the way around the world, in various inclinations at different altitudes to provide routes to many places. Carbon materials are also incredibly strong so the line can be made as strong as can reasonably be required.
The flotation layer also supports a hypersonic linear induction motor that could provide direct propulsion to a hypersonic glider or to electric fans on a powered plane. Obviously this could also provide a means of making extremely low earth orbit satellites that continuously circumnavigate the ring.
I know you’re asking already how the planes get up there. There are a few solutions. Tethers could come all the way to ground level to airports, and electric engines would be used to get to height where the plane would pick up a sled-link.
Alternatively, stronger links to the ground would allow planes to be pulled up by sleds, though this would likely be less feasible.
Power levels? Well, the engines on a Boeing 777 generate about 8.25MW. A high altitude solar cell, above clouds could generate 300W per square metre. So a 777 equivalent plane needs 55km of panels if the line is just one metre wide. That means planes need to be at least that distance apart, but since that equates to around a minute, that is no barrier at all.
If you still doubt this, the Hyperloop was just a crazy idea a century ago too.
