A Texas company claims it can grow algae at such volumes that they can produce 100,000 gallons of "algae oil" per acre per year. This compares to corn which yields only 200 gallons of ethanol per year. The secret is a vertical system that allows a 3 dimensional growing space for the algae and a closed-loop system that keeps contanimants out and re-uses water with more than 90% efficiency. Given the numbers, one-tenth of New Mexico could supply all the land necessary to provide 100% of the United States' transportation fuel needs, assuming all vehicles can burn diesel fuel.
The really impressive thing about this company is that they are not seeking public funding and have many venture capitalists waiting to help. This is a project that could change the face of the earth because it takes carbon out of the air (via the algae) to create the lipids in the algae that are then converted to bio-diesel. And anywhere there are moderate temperatures and good access to sunlight, you can have a "factory."
