It's a matter of efficency, not of changing the laws of physics.

If it costs as exactly much energy to get hydrogen as you get when you
use it (perfect efficiency) it still isn't a fuel, it is just a good
battery. Unfortunately the losses are pretty big.
This is great for the space program where cost is no object but not
very practical competing with Li ON batteries, or even lead.

I suppose you could start with elemental hydrogen but most commercial
hydrogen comes from natural gas wells The problem is it is a lot more
expensive.
Why not just use the natural gas? The CLNE solution.


Why not use batteries that can be recharged by a small amount of a known
commodity that's already fairly inexpensive... diesel or natural gas or
whatever. Diesel is ubiquitous, which decreases the hassle factor. Someone
said you still have to get the hydrogen right?
