To put this in perspective, this area represents approximately 10% of the area devoted to growing soya in the US. Biohydrogen reactors use a method of photobiological water splitting which is done in a closed photobioreactor based on the production of hydrogen by algae. Algae produce hydrogen under certain conditions. In 2000 it was discovered that if C. reinhardtii algae are deprived of sulfur they will switch from the production of oxygen, as in normal photosynthesis, to the production of hydrogen -- P2P Foundation: http://p2pfoundation.net - http://blog.p2pfoundation.net Connect: http://p2pfoundation.ning.com; Discuss: http://lists.ourproject.org/cgi-bin/mailman/listinfo/p2p-foundation Updates: http://del.icio.us/mbauwens; http://friendfeed.com/mbauwens; http://twitter.com/mbauwens; http://www.facebook.com/mbauwens
