I saw today’s cow in my Facebook newsfeed as part of an NPR (National Public Radio) article on the Pennsylvania Farm Show that took place a few days ago. There was a butter sculpture on display at the event. This is the cow photo used in the NPR article:
After performing a quick online search, I was able to find a photo of the whole 1000-pound sculpture. Quite an impressive feat knowing this is all made out of butter.
The big question was what to do with the sculpture after the event. A farmer offered not to let it go to waste and throw it into his manure pit. There it will decompose, being eaten by bacteria, and in the process it will heat up and produce methane gas. The gas will be used to generate a few days of electricity. How cool is that?
So I’ve learned something new today. I thought only the cow’s “natural emissions” produced methane gas, but even the butter the cow can be full of gas.
