Interesting report from Green Tech Media:
Teach a man to fish and he’ll drive 200 miles. That’s one way to describe the new business strategy at LiveFuels, one of the earliest algae fuel companies.
To date, the company has largely discussed raising different species of algae in open ponds to produce fuels. Today, it stated that it will grow algae, but then let filter-feeding fish eat it. It will then capture the fish, squeeze them for oil, and then feed the oil to a refinery.
Having the fish feed on algae clearly will require more algae than would be required if the algae were harvested directly. The company will also have to find ways to optimize the growth of its grazer fish and algae. – from GreenTech
