greetings! i didn't quite know what to file this question under, it kind of affects a lot of scientific sectors. as i have found out by watching tv, browsing the madsci archive&library and various websites, fuel cells based on the reaction of hydrogen with oxygen are really coming soon. now, to make a fuel cell emission-free (not speaking of water that can be condensed and re-used), one needs to eytract hydrogen and oxygen from water (correct me if i'm wrong, but there does not seem to be a economically and ecologically better suited substance).to extract these, one needs current. to have current, one needs power plants. the problem there is, that we can't use coal-powered plants (that would render the whole fuel cell process obsolete). the nuclear power plants seem nice, but i asked a physics professor from the eth zurich, and he told me that the designs used to build nuclear plants are outdated since, like, 40 years, and there _is_ a problem with the highly radioactive leftovers from nuclear fission. but i also assume out that energy supply matching the existing demands will be impossible in the future without nuclear power, as the "cold fusion" is nowhere within reach, and the photovoltaic cells and all the dams and wind-powered plants won't cover the need. so my question is: how are we going to get enough energy to produce hydro- and oxygen for all the cars in the world AND meet the power consumption needs?
