Widescale Biodiesel Production from Algae [ 2004 ]
University of New Hampshire, Physics Department ^ | revised August 2004 | Michael Briggs

In "The Controlled Eutrophication process: Using Microalgae for CO2 Utilization and Agircultural Fertilizer Recycling"3, the authors estimated a cost per hectare of $40,000 for algal ponds. In their model, the algal ponds would be built around the Salton Sea (in the Sonora desert) feeding off of the agircultural waste streams that normally pollute the Salton Sea with over 10,000 tons of nitrogen and phosphate fertilizers each year. The estimate is based on fairly large ponds, 8 hectares in size each. To be conservative (since their estimate is fairly optimistic), we'll arbitrarily increase the cost per hectare by 100% as a margin of safety. That brings the cost per hectare to $80,000. Ponds equivalent to their design could be built around the country, using wastewater streams (human, animal, and agricultural) as feed sources. We found that at NREL's yield rates, 15,000 square miles (3.85 million hectares) of algae ponds would be needed to replace all petroleum transportation fuels with biodiesel. At the cost of $80,000 per hectare, that would work out to roughly $308 billion to build the farms.

The operating costs (including power consumption, labor, chemicals, and fixed capital costs (taxes, maintenance, insurance, depreciation, and return on investment) worked out to $12,000 per hectare. That would equate to $46.2 billion per year for all the algae farms, to yield all the oil feedstock necessary for the entire country. Compare that to the $100-150 billion the US spends each year just on purchasing crude oil from foreign countries, with all of that money leaving the US economy.

I knew that Aglae in my pool was worth something.

Algae will likely be the future....all the other don’t look as good. We don’t have to change the industry completely.

Plus algae can feed on carbon, even directly vented from coal plants. A two edged sword. With a more reduced price it can compete and replace petro, while getting liberals off the coal fear.

Yea !!

My Jetta is Diesel and I have used Bio-Diesel in it from time to time when it was cheaper... Usually it’s not,b ut no conversion is needed as mine is the older engine that can run on 50,000ppm sulfur... Kerosene or Bio without any problem.

We need to shut of the flow of cash to Allah.
