Park Spark transforms dog doo into light

It’s definitely a good thing that so many dog owners scoop their pooches’ poop, but what happens to that waste after it’s been bagged and discarded isn’t so great... usually it ends up fermenting in a landfill, where it poses a health risk, attracts vermin, and releases harmful methane gas into the atmosphere. Pickling it and turning it into plant fertilizer is one option, but American conceptual artist Matthew Mazzotta would like to see it fed into digesters that use it to produce methane gas, which is then used for fuel. To that end, he has created a sort of demonstration project/art installation called Park Spark, at a dog park in Cambridge, Massachusetts. It features a lamp that lights the park at night, powered by nothing but canine doo-doo.
