Ouch!
Hydrogen requires a source of energy.
So does gasoline - oil. Natrual gas and coal burned straight do not of course.
If you are talking about replacing any significant number of fossil-fueled vehicles with hydrogen vehicles, you are going to need an energy source that is not a gimmick and is much cheaper than current methods of generating electricity.
When mention is made of NG, coal, even oil, the hydrogen is cracked right from them.
In other words, hydrogen cars will make sense when you have a fusion reactor in your garage.
Not if cracked from the three above. We need not be restrictive - H can be derived from electrolysis supported from Nuclear power and Hydro-electric "waste" energy (Which is substantial since electricity can't be effectively stored...unless it's "converted" to hydrogen!)
Until you realize that you are just going to sound stupid to people who understand basic math.
How do you think you sound to the natural gas and other industries pushing this?
Bush should have spent that money teaching science so that this issue will go away.
But he didn't - what does that tell you? BTW, check out energy sites re: explosion in NG exploration. Also, those quietly discussed Alaskan NG pipeline bills in Congress for starters.
The point is a million barrels of oil produces several hundred thousand barrels of fuel. If you "crack" hydrogen from oil, coal, NG you lose the energy from the carbon and so you'd need several times more oil to get the same energy.
The only source of hydrogen that makes sense is nuclear.
This is like explaining calculus to a chimp. Why don't you figure out the economics of the thing, go into business and become the next Rockefeller? Hmm?
Work out a businesss plan. Figure out how much you will have to charge for hydrogen.
But you won't. You will just rant ignorantly on, and vote for congressman who are just as ignorant. They will raise taxes to fund this nonsense, which will never work and just lower the standard of living for all of us.
If you can't write up a business plan and make money on it, then it is a bad idea you should just drop. If you can make money on it, go do it and quit talking about it before someone else beats you to it.
