Hi,
I recently talked to my brother the chemist about
hydrogen fuel cells. I asked him if he thought that there would be a
problem with hydrogen fuel cells making the environment "wetter".
I guess I still don't quite understand the situation with them, but my bro
said that the hydrogen that would be used for the cells would come from water,
therefore the amount of water in our ecosystem would remain the same. Now,
my question is, would that make any sense? Won't it take energy to
separate the hydrogen and oxygen atoms? Is there any energy gained this
way? Or is it a case of borrowing from Peter to pay
Paul?
just wondering.....
