Poop-Powered Car Used by Denver Zoo

The Chevrlet Volt or Toyota Prius might offer real alternatives for saving the cute and cuddly polar bears and the whales, but what if you really want to make a difference.
How about this for a green twist: the Denver Zoo is turning a 20-year-old motorized rickshaw from Thailand in a vehicle that uses regenerable energy that comes from... solids... OK, we’ll say it... from animal poop, mainly elephant in nature.

The system turns the poop into gas, which is then converted into electric energy. Which means you won’t have to deal with the repulsive idea of riding around in a vehicle that smells like the back end of an elephant.

The system will eventually be enlarged to a more industrial scale by the Zoo, who will use the poop to provide 20% or its energy needs.
