Low cost algae biofuel in 18 months, hopes Sapphire Energy

Rather than growing algae in expensive, enclosed reactors, they plan to test growing algae outdoors in ponds.

Algae, in theory, has the potential of producing 5,000 to 10,000 gallons of fuel per acre, higher than most other forms of biomass by a wide margin. Algae can also grow in brackish water on marginal land, so it doesn’t compete as directly with food agriculture.

If algae biofuel ever becomes readily available at a reasonable price, it will change the energy business forever.
