I'm speculating here, but think about ruggedness and costs of manufacturing associated with a moving keyboard.

Manufacturing:

• Testing a moving part
• Competing with thinner phones (keyboards add thickness)
• Layout of phone given the need for a hinge, PCB, battery in the package
• Relatively unique design; I imagine the assembly line for slate phones are very simlar
• Finding a supplier for the keyboard

Ruggedness:

• Phones are quite water resistant now, a hinge gives more opportunities for leaks
• Moving parts break
• Individual keys break

I think the only hope is for a nerd targeted phone, as people who need to type commands with weird symbols really benefit the most from a physical keyboard. But I am not holding my breath, and a bluetooth keyboard can cover the instances where I need to type in that fashion.

So many definitions are needed to answer this question. Assuming that written text is considered media, how do you define a unit? Is it time spent with the media? Is it the number of distinct topics viewed (each episode of a show count as one)? Or is it the storage required for the media?

SO MANY THINGS ARE UNDEFINED

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.

I doubt that a fab could even be built as Russia is on a couple technology transfer lists. When they state Russian made I imagine it will actually be sent to TSMC or other foundry with design in Russia

You still control it, yet it is remote and will be properly searched when you die. You can put a usb key in or some paper documents with the relevant information.

If KSP has taught me anything, it is that computer controlled rockets (MechJeb) can land vertically very reliably.

I'm still waiting for this to be mainstream

Thank you for posting this, it is almost exactly what I've been looking for. I wish there was a discount version without the radio/solar for urban backpacking, and a colour eink would really help with maps, but I'm thrilled to see demand for a traveler's eink device.

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.

Just because Microsoft does not love XP anymore doesn't mean you should ignore it!

Or wait- I guess you mean Linux DEs. Which one looks the most like Windows95? I bet you that one will win.

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.

Hydrogen vehicles these days are series hybrids with a PEM fuel cell and Li battery pack. Think of a Volt but fuel cell instead of ICE.

Just let these innovations arise in other countries if the USA has such a backwards infrastructure. Even credit cards are more secure in other countries (chip and pin may be flawed, but it is still better than the magnetic strip and signature of the USA).
