Indeed, fuel cells are interesting energy converter: You could distribute hydrogen by pipe and convert it to electricity where and when you want it. The primary energy I advocate is CH4, first from gas wells and then from undersea clathrate, the "burning ice". The world reserves are in the ten billion billion tons, as much to power the civilization at present level for one billion years. The rreal problem is then the green house effect, even if we can tolerate it for some centuries. The long term solution is, I think, solar energy from space. Nuclear plants are not net energy producer: building them consume too much fossil fuels, they are at most energy converter, from oil to electricity. The low cost oil reserves will dry up in the comming years, that is not to say we can't continue with it, we will pay more for it and we will give more money power to bin Laden-like org. The real, short term problem with oil is not its complete depletion or even the green house effect, it is the muslim effect :-) Yvan Bozzonetti. --part1_11a.1badba74.2b2f6e96_boundary Content-Type: text/html; charset="US-ASCII" [ AUTOMATICALLY SKIPPING HTML ENCODING! ] Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=20633
