researchers at the Lawrence Berkeley National Laboratory (Berkeley Lab) now claim to have produced an enhanced system [gizmag.com] that uses water and solar energy to generate hydrogen, which is in turn used to produce methane, the main element of natural gas, from carbon dioxide. Generating such gases from a renewable resource may one day help bolster, or even replace, fossil fuel resources extracted from dwindling sub-surface deposits.

Simply put, the process of photosynthesis turns light energy into chemical energy. In plants and certain types of algae, energy from incoming sunlight is used as the power source to synthesize simple carbohydrates from carbon dioxide and water. In the original Berkeley Lab hybrid system, a membrane arrangement of nanowires created from silicon and titanium oxide harvested solar energy and transported electrons to microbes where they used that energy to transform carbon dioxide into a range of chemical compounds.

Produces methane...Sorry, cows, you have been rendered superfluous.
