The Power of Dog Poop
The Park Spark Project was started by conceptual artist Matthew Mazzotta interested in exploring the relationship between people and their environment.
The concept is simple and beautiful (...though maybe a bit stinky): convert dog poop into usable methane gas to power a lamp (or other uses -- they're open to ideas!) using an anaerobic methane digester. This principle is similar to that of Purpose Energy, Inc, which I wrote about last week, which converts brewery waste into usable energy also using a methane digester.
The site does a good job of explaining in a really simple way how it works, and why burning methane is better than just releasing it into the environment directly (as what happens when organic waste is disposed in a landfill).
The project is based in Cambridge, MA.
Thanks Mick for the tip.
