Using Sunlight as Fuel

Scientist researchers in New Mexico discovered a way of using sunlight to recycle carbon dioxide and produce fuels like methanol or gasoline. Researchers said that the discovery works and could help reduce greenhouse-gas emissions. The idea of recycling carbon dioxide isn't new but was considered too difficult and expensive to do; since gas prices are soaring to 100 dollars per barrel, researchers are motivated to investigate recycling the carbon dioxide. For example, Los Alamos Renewable Energy has developed a working idea of using CO2 to generate elecrticity and fuel.
