The idea of oil on the water is anything but environmentally friendly. But according to the InterPress Service News Agency, one viable option for meeting our energy needs may be out at sea, as a Spanish company recently developed a system for producing massive amounts of biofuel from phytoplankton. These tiny oceanic plants can also grow in fresh water on land, or on moist ground, and while a plant like soya can produce 50 cubic meters of biofuel per square kilometer, algae can produce a staggering ten to twenty thousand cubic meters on the same area. Since this reportedly can be done at moderate cost and has cleaner emissions, the idea of putting algae in your engine may yet be a wave of good news.
