Sustainable and efficient biohydrogen production via electrohydrogenesis That's a link to the abstract and pdf of the original article, a FReebie. I haven't read the pdf.
Regardless of the fact that I think anthropogenic climate change/global warming is bunk, shouldn't we demand energy independence? Weren't tar sands and shale oil supposed to be viable at $70 per barrel of oil? I don't care how we get the energy that we need, whether it's ANWAR, offshore oil or methane clathrates, whatever. IMHO, anything else is better than supporting the likes of Saudi Arabia, Iran, Russia, Venezuela, etc., in the fungible oil market.
