Who's demanding tax money? As near as I can tell, GM/Daimler/Ford/Honda/Toyota are doing the lion's share of this all on their own. If any tax dollars are going there, it's because they have told the current administration it's a good thing. Why else would you think a guy like Spencer Abraham be talking about it? Because he cares? Right.
Come on, show us you car and do the cost per mile analysis for gasoline and hydrogen. Look at the different chemical reactions yeilding hydrogen. Look at the price of electricity from various sources
Do it yourself, junior. Then YOU post it. The information is at your fingertips (www.google.com). My point has been that the system possibilities haven't been explored yet, and that conclusions based on prejudice or political opinions are premature. I assume that the automobile companies HAVE done the analysis.
You have told us that no government money went into the development of computers. Oh please. Even ignoring the front end money in WWII, and the avalanche of money spent in the '50s and 60's, you'd still find that simply being an anchor customer for companies like SUN has dramatically influenced reasearch. It wasn't all done "because it was the best solution for the money". It was "we have to help the companies". You're simply making up nonsense to support your asssertions.
I am not the one promising a brave new world with hydrogen fueled cars. Until you can back up your assertion that hydrogen is such a wonderful panacea, you are full of it.
And I don't have to "prove" anything, because the readily observable reality is that we have a hydrocarbon economy.
Without a way to produce hydrogen in the same economic ball park as gasoline, gasoline wins hands down. That is the bottom line.
That doesn't mean it can never be done, in fact it may be possible with existing nuclear technology, but the same wild eyed radicals screaming for hydrogen have made that avenue impossible.
