I'm one of those that believe the technology exists, at least in crude form. The trouble I think you are missing is that hydrogen is exceptionally volatile. Remember the Hindenburg? If you don't, I guarantee that is what Congress thinks every time the issue comes around. Hydrogen is just too unforgiving for the masses of idiots to play with. Now, I have heard on occasion of various research with fuel cells and the like, and it would be great to see progress made in those directions. But again it is about being able to make a profit. If it costs more to make and implement than it can be sold for, there is no justifiable business reason to go ahead. You can do what you want to satisfy your philosophical ethics, and if you are independently wealthy, more power to ya! I simply cannot afford at this time to trade my 5 year old gasoline powered pick up truck for an over priced promise that I can have all the fuel I want for pennies if the resource is not there, the infrastructure is not there and the reality is not there. I don't have the time or room to devote to distilling my own fuel (not to mention various EPA laws involved). I have a truck for a reason, I use it to haul things from time to time. Will this new fuel power my vehicle reliably up to acceptable highway speeds while carrying a load, and do it for the same or less money than I now spend? If the answer is "no" anywhere in that equation, then I am better off keeping what I've got. My sacrifice was in getting a 4 cylinder when I could have opted for a 6 or 8 cylinder. I would have preferred 14 inch tires, but I was told they no longer put 14's on these trucks (sounds like BS to me...). I would have preferred cruise control...not an option on a 4 but available (at extra charge) on a six. A standard gets better mileage, I got the automatic because my legs won't allow me to shift like I could when I was a kid. Everything in life is trade offs. We all make decisions that impact the environment, the economy, the people and planet around us. It is impossible not to. The trick is to be as responsible with those choices as you can given the situation you find yourself in.
