Pond scum gets a good rap

That's right, algae looks to be the new corn when it comes to ethanol production. Recently, it has become apparent that corn is not actually necessary for the production of ethanol - virtually any plant matter will do and now Dow Chemical and Florida's Algenol Biofuels see algae and the Texas Gulf Coast as the prime source and place of new developments, as the Houston Chronicle reported Sunday.

Dow's huge Freeport complex will be the center for this new experiment. The idea is to set up long clear plastic tubes filled with salt water and algae across the flatlands of south Texas and then pump CO2 from refineries and chemical plants in the area through the tubes. The yield: ethanol.

This would promote both ethanol and biofuel production, a much cleaner source of fuel than petroleum and is just as versatile (it can even be used in plastics) as well as capturing and using CO2 in a sustainable way.

By making waste CO2 the carbon component in the production process, it cuts down on emissions. The CO2 output from biofuels is a fraction of that from petroleum.

Let's hope the experiment works.
