As predicted in 2003 - CNG will be the winner

Its Made From Corn, And You Run Your Car On It, But Its Not Ethanol

“We are very excited about this breakthrough because it may lead to a flat and compact tank that would fit under the floor of a passenger car, similar to current gasoline tanks,” said Pfeifer. “Such a technology would make natural gas a widely attractive alternative fuel for everyone.”

The National Science Foundation reports of a very interesting breakthrough. Using corncob waste as a starting material, researchers have created carbon briquettes with complex nanopores capable of storing natural gas at an unprecedented density of 180 times their own volume and at one seventh the pressure of conventional natural gas tanks.

This corncob “sponge” will allow for the storage of methane, a natural gas derived from rotting bio-waste. With this new technology comes the possibility of using waste methane from cow manure, food waste, heck even human waste to power your car. Read full writeup link here
