The second coming of biofuels

This latest article from Discover magazine sheds light on a new form of biofuel: green fuel. Unlike other biofuels which are derived from soy, this fuel comes from plant waste or algae. Useable fuel from algae can be produced at 35 times the yield that soy currently produces.

This new scientific finding has companies such as UOP (a main proprietor of green fuel) realizing that the future of automobile fuel will most likely be a combination of petro and non-petro fuel. The process in which to derive fuel from algae requires a small amount of petro fuel. However, unlike other renewable fuels, green fuel can be created in the same petro-producing facilities that stand today- thus eliminating the need for a change in infrastructure.

I see this as the next big thing for companies invested in the renewable fuels field to invest both time and money into. It's promise of a higher yield and relative ease of production make it a great prospect to get America off foreign fuels.
