Most research in algae-fuel production is being done in the private sector, but if positive signs and predictions hold true, using algae may be the best and most productive way to produce enough fuel to replace gasoline usage in cars.
Micro algae grow allot faster than other crops and the yield of oil from algae is estimated to be from 5,000 to 20,000 gallons per acre, per year which is 7 to 30 times greater that the next best crop.
Algae can also grow on marginal land, even desert area. The hard part is finding algal strain with a high lipid content and fast growth rate that in not to difficult to harvest.
Open pond systems have been given up for the cultivation of algae with high-oil content.
