Dog Poop Powered Park Lights
The Park Spark features a gas lamp fuelled by dog poop / Image Source: Gizmag
Last month we told you about a car that uses methane gas generated from the sewage-treatment process. Well, here’s another interesting project from an American conceptual artist Matthew Mazzotta who would like to see the dog poop fed into digesters that use it to produce methane gas, which is then used for fuel. The project/installation — called Park Spark at a dog park in Cambridge, Massachusetts — features a lamp that lights the park at night, powered by nothing but dog doo.
How does it work?

To use the Park Spark, dog owners scoop their dog’s poop in one of the supplied biodegradable bags and then drop it into a large airtight tank. After that they turn a wheel on top of the tank to stir the contents. Through a process of anaerobic digestion, microorganisms break down the faeces and produce methane gas. That gas rises and is ultimately released – and burned off – through a valve on the lamp. When burned, the methane is separated into carbon dioxide and water. Although CO2 is still a greenhouse gas, it is much less potent one than methane. The flame in the lamp burns as long as there is fuel to feed it.

Mazzotta is now trying to establish Park Sparks in other cities, and is open to suggestions for other possible uses for the gas that they create.
