Interesting article, but I wish I had a nickel for every time I have read about some new promising source of renewable or alternative energy. The difficulty always comes when trying to make it cost competitive with oil and carbon based fuels. Whatever happens, I would rather have the marketplace decide what kind of energy source is viable rather than have the federal government steer us in one direction or the other.
The marketplace will decide based on cost effectiveness, but the federal government can certainly provide R&D incentives.
