Leave it to an artist to come up with a creative solution to dog waste. Matthew Mazzotta harnesses the potential energy in dog poop and uses it to power a lamp in a Cambridge, Massachusetts park. Called Project Park Spark, here’s how it works.
Participants in the program collect their dogs’ output in biodegradable bags and toss them into a vacuum-like container. Bacteria break down the poop into various byproducts, the most important of which is methane. The methane is then used as an energy source to power a gas lamppost in the park.
And now, if you excuse me, I have to go walk Pablo. No shit!
