This technology isn't in the blue-sky or even beta-testing stage of the R&D sequence. It has already been proved in the lab, and it's now being proved in the marketplace, where some very big clients -- among them major airlines, the U.S. Navy, and Bunge, one of the world's largest agribusiness conglomerates -- are placing orders for millions of gallons of algae-derived biofuel from dozens of manufacturers…Algae-derived hydrocarbon has been something of a biofuel holy grail for decades now. Scientists have long known that the yucky green film commonly found covering ponds and poorly tended fish tanks can take two of the planet's easiest-to-find ingredients -- light and CO2 -- and turn them into one of the scarcest: oil.
