Using Your Dog Poop to power a light!

I have been sent this great article by David Rikaln from Selfhelp.com.

This really isn’t about Personal Development but it is about thinking “outside the box” and using what we have.  This guy is not a scientist but an artist.

Essentially you put your dog poop in the system and it powers a light with the gas, methane.  Cool right?  Have a look at the video.  I am sure it is not that efficient yet but you have to try these things.  Imagine if all parks had these?  How much could we power with them?
