Pond Scum becoming new oil?  

The current fuel crunch, driven fundamentally by a rising global demand for oil, has spurred debate among consumers, political leaders, academics and entrepreneurs about plausible alternatives.

A good bit of the discussion has focused on biofuels, commonly defined as energy derived largely from plants and crops like corn, soybeans, switch grass among other sources.

"It's become obvious that the biofuels sector is much more viable now that the prices of oil are high," said Beth Ahner, an expert in biological and environmental engineering at Cornell University.

Algae, thought of as pond scum by many people, is an intriguing biofuel prospect, some researchers and entrepreneurs say.

CNN.com producer Cody McCloy, who's driving across the United States in a biofueled diesel-powered vehicle, is a fan of algae-based fuel, after running it much of the day on Monday during his travels through California.
