Do thousands of guinea pigs running on little wheels generate the electricity?

How much poop can 1,000 guinea pigs make? Oh, about three tons every month! All this pig poop produces methane gas. The gas is trapped and stored in inner-tubes! (For more on this part of the process, see this dog-poop power story.)
The poop also produces a dark brown liquid plant fertilizer. I call it guinea pig diarrhea, but the locals call it “Caca Cola”. The following video is about the whole process.
WARNING: The British narrator matter-of-factly calls guinea pig poop “sh**”, so please don’t watch if that will offend you!
