Bovine energy is a hot topic in biofuel research. Don’t laugh. There are 1.5 billion cows on planet earth and each of them manufactures an average of 100 pounds of manure a day. That’s a lot of methane gas.
Before I read about bovine energy, I pictured it pretty much the way the folks at the One Laptop Per Child initiative are using it. (see photo below) Not very efficient.
But as I read more, I began to understand how serious a source of energy cows could be. With a methane digester, even a small farm can recycle the gas cows produce in their manure to produce some serious electricity. The farm in the video (middle) brings in an extra $30k a month from selling their cow-generated electricity.
Instead of asking “got milk” maybe we should be asking “got fuel?”
