This idea was so out there that I thought it appropriate to pass it along. Instead of a solar panel you have a panel which holds engineered, photosynthetic organisms in a non-freshwater solution. These organisms directly make checmicals and biodiesel from the sunlight and carbon dioxide. The system is expected to go online by 2011 and bring biodiesel fuel at the cost of around $50 per barrel.
"Through advanced genome engineering, we have developed proprietary, product-specific organisms that catalyze the direct conversion of sunlight and CO2 to useful fuels and chemicals".Read More
