As gas prices continue to rise, alternative fuel sources continue to be a hot topic in the scientific community. To that end, scientists at UCLA have just released the results of a study in which they successfully generated a liquid fuel by using solar powered electricity, carbon dioxide, and genetically modified microorganisms. The microorganism was placed into an electro-bioreactor with carbon dioxide as the sole source of carbon and solar-generated electricity as the only energy source. Treated properly, this genetically-altered microorganism was able to produce isobutanol — an organic compound that is a colorless, flammable liquid that could potentially be used as an alternative to gasoline in a combustion engine.
