I admit that when I saw his design the first thought was backpacking only. Imagine washing something burnt off the bottom of that; I would only want to boil water in it.

The issue with this pot in backpacking is that it looks heavier, and people get crazy when it comes to losing a couple grams. I imagine that you will save fuel in the long run but you also will have trouble storing stuff in your pot (my 1L pot is the perfect diameter for butane canisters to slide in).

Props for the invention, and honestly if you want to make something expensive and marginally better than the rest of the products on the market backpackers are a decent choice.

It is a density issue. Hydrogen is difficult to transport and store. One solution would be to truck ammonia to the service station, where you can dump it into below ground storage and generate/compress H2 on demand. The other option would be to perform the H2 generation onboard of the car, but the issues of the toxicity of ammonia would still require fancy fuel tanks so I think the local generation model would be superior.

No, but I don't know of any Chinese companies producing steppers or any other of the multi-million dollar tools required to fab a processor. You may be able to get away with used equipment but then you are giving yourself a handicap and won't get any support from the parent companies.

It isn't that far off. An eink reader designed for travel, with lonely planet or wikisherpa included. It is also one of the few proper applications of a colour eink screen, as maps do not need to be vibrant but colours are vital to a map.

I could go on, but I know this is a fantasy. I hope one day a colour eink android or linux tablet arrives so I can install applications similar to this use case, but I am not holding my breath.

Convergent evolution also depends on how you define two features similar. For example, the convergent evolution of oxygen carrying blood in Cephalopods could be a counter example to the prediction argument, as their blood has oxygen bind to copper.

So both bloods were evolved to perform the same task of moving oxygen, however they use two different mechanisms to perform the task.

Optimization hinders evolution.
