Cow power rocks ...

Native American used Buffalo dungs for heating and cooking. I learned this early on from a history class. I guess I should have known people would think of ways to harness energy from cow chips. I just saw Amanda Congdon's piece on a family farm that uses their cows' poop to generate enough power to light 400 houses. Since I know a little about wastewater plants, it was easy for me to follow how the waste are collected in a digester and the waste gas from it are burned for energy generation. I am so impressed and laud those who are using waste stream and converting them for useful purpose.

Here are a couple of links to the story, Amanda Congdon piece and a news article.
