Puppy poop power

OK, I'm all for alternative energy sources. I'm also opposed to stepping on piles of dog poo when I go for my morning walks around the 'hood. This could be a solution that I could support on two levels. The Arizona Republic, via the Associated Press, says the doggy-doo could be magically mulched and the methane gas used as a power source.
So far, they only plan to power one street light.
Hey, it beats scraping off my shoes every morning.
