Scientists who are searching for the ultimate alternative fuel source have tried everything from corn to coconuts. Miles O'Brien found a guy who believes that one day we'll be filling our fuel tanks with a scummy alternative. Glen Kertz believes he’s found the magic bullet alternative to oil - it's pond scum but without the pond - and that's what sets his idea apart. Kertz is flowing, and growing, algae through a long-winding journey in clear plastic bags suspended in a greenhouse. He calls the system Vertigro. The algae grows fast and is siphoned off continuously. The algae oil is extracted, ready to be refined into fuels like biodiesel. Kertz says he can produce a hundred thousand gallons of algae oil per acre per year. Compare that to corn - which yields about 20 to 30 gallons an acre. The Vertigro facility is a long way from the corn belt, in the desert near El Paso.
