British inventor Brian Harper has come up with a very different idea to power street lights. He come up with a bio-gas street light that is powered by, dog poop. And, it seems to work pretty well!

So, when you're walking your dog and she needs to go, you simply grab one the bag scoopers provided. Next, you toss it in the bio digester and give the handle a few turns. The bio digester then collects the bio gas and powers the street light.

I mean, you're going to pick up your dog's mess anyway, might as well put it to good use right? I would absolutely love to have a few of these lamps in my back yard, as long as it doesn't produce Ambassador Bridge kinda stink.
