Thats a really cool technology, and i think honda just came out with a car that uses that same type of idea. But wouldn't it make since if they used hydrogen as the fuel, so we could use it in "normal" cars? (i.e. not brand new electric cars) Apparently there are some guys in Cali that can covert any car to run on natural gas, and i think he said the highest price in the nation was like $2.30 a gallon and the lowest around .60. The only problem i see with that is that if enough ppl do it, (because of supply and demand), wouldn't those prices start to go up....just like gas did? (but then again, if that happened and we could produce the natural gas domestically, it seems the normal gas prices should drop...just a thought)
