Denver Zoo Uses the Power of…Poo…

It’s only a prototype now, but the Denver Zoo is using animal poop and trash to power an electric rickshaw. The plan is to test the fuel’s efficacy to eventually power an entire elephant pavalion. It’s all part of a green experiment that will save money. Photo Credit: thelearnr via Flickr

Nice, but I still think zoos ought to be illegal & replaced by animal sanctuaries.

So this will open up a whole new reason to keep animals in captivity. It wouldnt suprise me to see people get as greedy over crap as they now do oil.

WOW! we have discovered so many ways of creating energy sources. such as poo,yellow corn, the NYC tidal wave experiment, wind power,solar power, just to name a few that i can think of off the top of my head. with so many ways of developing clean green energy sources, coal power, diesel and other hazardous sources need to start being limited or eliminated all together. if anyone has any more info about other new sources of energy add me as a friend and tell me about it. i would love to learn more about this and other green topics

The Perth Zoo in Western Australia sells bags of 'Zoo Poo' for gardeners, but also uses it to fertilise plants for animal food. They grow a lot of their own food.
