Argument: Algae biofuel requires less land; good for the environment
"Algae: Not Only The Best Biofuel By Far...". Ecoversity - For the algae-culture projects which use large growing ponds, the potential biodiesel production per acre is 30 to 100 times greater than obtainable with corn, soy and palm oil. However the most efficient systems, called photo-bioreactors, stack clear tubes of water with algae in the sun, requiring very little acreage for significant production. This is the system we are demonstrating at Ecoversity.
