From the link I already posted:Do me a favor: calculate a "rough" estimate of how much space would be required to grow enough algae to fill up a 55 gallon barrel (say one acrefoot, a water covered measurement, per 100 barrels). Now, consider you will need tens of these barrels to convert enough to fill ONE barrel with actual fuel. What do you think the cost would be to keep "environmental conditions" favorable for massive algae growth (how much energy will it take?)? Will it contaminate our waterways and harm the "wildlife"? Will it "affect" our drinking water? Who will monitor it? How many agencies will have to be created (filled by friends of Obama) to "regulate" it?
This is another money laudering scheme (PONZI if you insist) that the O is planning on using in his next term. Billions will be invested in companies that will declare bankrupcy after WASTING valuable energy for a "show" for his green zombies. And your response at that time will be: if only we had "spent" more....
Briggs used the numbers from NREL's Aquatic Species Programthat one quad (7.5 billion gallons) of biodiesel could be produced on 200,000 ha (roughly 500,000 acres) or about 780 square milesto compute that 140.8 billion gallons of biodiesel would requre 19 quads (140.8 ÷ 7.5).This would require about 15,000 square miles (19 x 780), or about 9.5 million acreswhich he notes is only about 12.5% of the area of the Sonoran desert of the Southwest. So using algae as a source of oil for biodiesel with the NREL productivity assumption, the acreage required is less than 3% of the 450 million acres now used to grow crops.
Based on a UNH research project, (8) Briggs then estimates the total cost of producing 140.8 billion gallons of oil (unrefined) for biodiesel at $46.2 billionsubstantially less than the $100-*150 billion that the US currently spends to purchase foreign crude oil.
Logistics:
how are you going to seal the ground to reduce water loss
how are you going to cover 15,000 square miles with enough water
how are you going to stop mosquito populations from exploding
how are you going to feed the algae
No environmentalists want to answer? What's the matter, can you see another "pipe" dream?
