Lights Powered by Dog Poop! (VIDEO)
Yes, that’s right. In Cambridge, Mass., a new program called The Park Spark Project invites dog owners to dump their biodegradable dog poop bags into a unique tank. Then they turn a wheel to start a process that allows microbes to turn the poop into methane gas, which creates power for lights at the park.
Pretty smart: bright lights, instead of smelly trash cans!
