The use of germs to produce biofuels has been in exploration since the mid-1990s, but finding the right organisms is a difficult task. The horse rumen has a vast array of environmental bacteria and ...something else. Could this be the treasure trove scientists are looking for?

The quiet revolution is already well begun in the biofuel industry as it enters it's high-growth stage -- and it is only going to get better from here. Some cities have done the calculations, and surprise! -- it's more cost effective to re-process that oil than to deal with the harm to the environment from toxic used oil. Quite unlike fossil-fuels, which cause a huge net gain to our atmosphere -- the CO2 equation couldn't be better for plant-based diesel.
