Gallons per acre of biodiesel from a CO 2-fueled algae farm

REALITY FACTOR

which man-made microbes could then convert to fuels. Chu expects biological processing to be far more efficient than the energy-intensive processes, such as steam explosion and thermal hydrolysis, currently used to make ethanol.

With oil prices approaching $80 a barrel, bioprocessing may not have to wait for life-forms built from scratch. GreenFuel in Cambridge, Mass., has installed algae farms at power plants to convert up to 40 percent of the CO2 they spew into raw material for biofuels. The company claims that a large algae farm next to a 1-GW plant could yield 50 million gallons a year of ethanol. "There are great opportunities here," Chu avers. "And not only that—it will help save the world." ®

▲ Greenhouse-covered pools similar to the lake in Biosphere 2 might one day grow novel microorganisms, plants or algaes designed to produce hydrogen, sequester carbon dioxide, or convert crops into fuels.
