We talked not too long ago about generating energy with bodily fluids, and more weird sources of renewable energy seem to be popping up every day. Now, a park in Cambridge, Massachusetts is trying out lamp posts powered with dog poop.
If common courtesy isn't enough to get dog owners to pick up after their pets, maybe this MIT-funded project will do the trick!
The Park Spark Project uses an underground Methane Digester to turn doggie waste into usable energy. Dog owners pick up their pups' waste using special bags that they toss right into the digester. Once you toss the bag inside, you give the machine a quick stir, and it burns the methane to produce fuel.
Not only does the project mean free, clean energy for parks, it means keeping all of those plastic bags of dog waste out of the landfill. Like any kind of organic matter, dog poo produces methane, a greenhouse gas 23 times more powerful than CO2, when it breaks down in a landfill. The whole basis of this project is to harness that methane to power lights and other park amenities.
Right now, they're deploying the project in Cambridge, but they hope to expand it to parks in other cities.
