The problem with hydrolysis is still this: It takes more energy to separate oxygen from hydrogen in water than burning the hydrogen could ever create, so any hydrogen fuel cells would need to be plugged in at night (or plugged in some where) to perform the hydrolysis.


Its not really a problem with anyone bieng in bed with anyone anywhere. Its a simple physics principle: There is no such thing as a free lunch. (or, the greater number of transfers of energy, the less effecient the system).

And, since most areas use non-renewable power sources for the electrical energy (In CA I think some 65% or so of electrical energy comes from non-renewable sources) regardless of if you have an electrical vehicle, a hydrogen fuel cell, or a standard internal combustion engine, all are using fossil fuels (and actually the electric cars are less effecient, gleaning about 11% of the origianl potential energy from the fossil fuels, while and internal combustion engine gleans about 17% of the original potential energy from fossil fuels.)

So, until fossil fuels are so expensive that solar wind and hydroelectric become cheaper sources of energy, or environmental regulations let up to all nuclear power more feasible, prices of powering vehicles will continue to go up.

If anyone is interested, I did a study of the efficiency and energy loss of various forms of transport for a class a few years ago. The data is all from 2004-2005 but its still a good essay if anyone is interested.

But, besides all that, that torch in the video looks awesome.
