Your characterization of airplane crashes as being unsurvivable is incorrect. "since 1983, more than 95% of the passengers survived", says National Transportation Safety Board. https://www.ntsb.gov/news/pres...

I had this problem when I broke my wrist. It turns out that it is pretty easy for your brain to learn to type one-handed if you simply use a special shift key to make each half of your keyboard be a mirror image of the other half. This can be accomplished in software, using the space key as the special shift, but there is a patent on the technique, and software drivers that used to be available are gone. You'll learn this way faster than any of the chorded keyboards. I have found the Matias Keyboard, which implements this technique in a hardware keyboard, to be a great solution. It's not cheap, but it works. http://www.matias.ca/halfkeyboard/index.php?refID=7

Depends upon what you want to measure, especially the frequency. I would start with a search for used equipment at HSC (http://www.halted.com).

Exactly. And that means that you would get more fuel efficiency by allowing the alternator to run without an electrical load. If you load the alternator to drive hydrolysis to generate hydrogen, then you consume more energy (to drive then alternator) than you produce (to generate the hydrogen). It's basic physics. Each conversion process (engine kinetc energy to electicity via alternator; electicity to hydrogen via hydrolysis; hydrogen to engine kinetic energy via combustion) is inefficeint -- probably under 50%. So the whole gizmo should reduce overall fuel efficiency, not increase it. You can't increase the efficiency unless you convert some energy which would *otherwise be wasted* into hydrogen. That's why a hybrid combustion/electric engine works. It converts the kinetic energy of braking/deceleration (which would otherwise be wasted as heat) into electricity. But a combustion engine's alternator just sucks kinetic energy that was otherwise destined to drive the vehicle forward.
