Oil from Algae
US NREL Aquatic Species Program
Algaculture
"Microalgae have much faster growth-rates than terrestrial crops. The per unit area yield of oil from algae is estimated to be from between 5,000 to 20,000 gallons per acre, per year; this is 7 to 31 times greater than the next best crop, palm oil (635 gallons)."
