"A California dairy has converted a pair of 18-wheelers to run on biomethane produced from cow manure, creating what is believed to be the nation's first cow-pie–powered trucks."



Also, I saw on the show "dirty jobs" where another dairy was doing this, but instead of running their trucks, they were running a power plant.




some exciting stuff to think about!

one more waste product that will no longer be waste, and one less set of trucks dependent on non-renewable resources!


pretty sweet if you ask me!
