[quote][b]Posted by:[/b] free tibet The trouble with hydrogen power is, you need a lot of electricity in order to extract the hydrogen from water. You are converting water to hydrogen, then back to water again; it's not very efficient. And of course, the electricity you need to obtain the hydrogen in the first place is made using fossil fuels, which pollute the atmosphere.[/quote] Yes energy is need to extract hydrogen from water, but did we forget that fossil fuels arent the only form of energy out there? we have wind power solar power even geothermal power (in select parts) all those meathods of power can be (and is) use to aid in the extracting of hydrogen we also have nuclear power to aid us, though toxic waste isnt good... we are also researching, i think its called "cold fusion", in that energy is made with out the bad side effects (H + H + energy = He + energy [i think]) just remember that oil will be $600 a barrel in 40 years (the best numbers), if we continue on our current path (oil is about $70 barrel now) ============= on a side note some ppl have gotton hybrid cars to do 250 mpg, and could be possible to do 1,000 mpg
