Could Dog Poo Power San-Francisco? Ehh… No.

An ambitious project funded by San-Francisco taxpayer aims to generate energy from dog poo:

“If you took one ton of a degradable material, dog poop and food scraps together, you could produce 50 gallons of liquid fuel,” Reed said. “If you took 80 tons of this material, you could produce enough energy to produce [power for] a thousand homes.”

Trucks take the food scraps from restaurants and pet droppings from doggy day care, and then it gets ground up into what’s called manufactured biomass, which goes into a machine called a digester that converts it all into methane gas.

Burning that gas produces energy in the form of electricity, natural gas and liquefied natural gas.’

Wow, it’s that simple. Well, no. There are a few problems in that process. First of all, you would need a very large (gigantic!) air tight container collecting all the methane gas without the presence of air.This would create a massive risk of disease as well as a danger of a methane explosion! The next problem is, once the material inside this giant infected, explosive container has been depleted of methane, who will go in and clean it all out and refill it again? Not me.

Then again, the good citizens of San-Francisco have paid for larger white (green?) elephants before so one more giant pile of dog poo can’t hurt. Right?
