"Because fuel cells produce nothing but a little water, the only way they can pollute the atmosphere is when the hydrogen used to power a fuel cell is pulled out of the air and compressed."
"What you are really seeing is the birth of a commercial industry," Yes, indeed. And a much needed birth it is.What an exciting time to be alive!POWER to CHANGE the WORLD!!!
Get real.Lets see, we are going to extract H2 from air (concentration 0.00005%), purify it, compress it , us it to run a fuel cell and use the power to not only to extract more H2 but run an automobile too.HmmmmmmmCan you say 2nd Law?
