Solar power could match fossil fuel cost by 2011 by using Stirling engines that convert solar power directly to mechanical energy Interesting article. I don’t know enough to dispute or add to the article. I do know that the Insititute for Biological Energy Alternatives (Craig Venter’s new project) is looking at sea-life to find more efficient methods for solar conversion than is currently available through standard photosynthesis and that they are hoping to find solar conversion techniques with efficiencies above 50%.
