After asking a question about back up electricity here it became very
obvious that there are a lot of very smart people here. There are a
lot of people talking about Hyrogen Cell technology and I know that
both Ford and GM have programs, which would be excelerated with a
little government help. I have heard that this technology could be
productive in less than 20 years and now I am thinking it might be the
ultimate solution, not only could it power our cars but generators and
possible heat our homes. Not that it would help me a lot at my age
but for the future, it would be nice to know we haven't left behind a
total mess. Anyone know where we are with this, how optimistic is 20
years?
