Great and interesting thread. My two cents:
I wonder how much pollution, if any, the oil manufacturers, plants, rigs, spilled tankers, gas transport trucks, ect., make to bring the fossil fuel we are using now to us. And then, we fill our tanks (cursing at the price), and create even more pollution.
How much does that weigh vs the pollution to create hydrogen fuel where the end result is completely natural.
I think that if this hydrogen technology takes off, it would be smart to create an industry where most components used to deliver this new energy source to us, use hydrogen. Ultimately minimizing pollution. I know that it will take a lot of energy to produce the new fuel, but how would that compare to what we are doing now.
If more vehicles use hydrogen, it would mean less pollution, but require more energy to produce the higher demand. In the end though, the only polluter would be the manufacturers.
Im totaly ingnorant to this technology, but was is the ratio of end waste to produce the same amount of product between the two sources?
