The 700 cows on Brett Reinford's dairy farm are making more than just milk.
Each day, the girls are producing 7,000 gallons of manure. And that smells exactly like you'd imagine. "We had gotten complaints from neighbors in the past that had said, 'Hey, it stinks too much. Can you do something about it?' " Reinford says.
So he looked around for a solution and landed on a device called a digester. A digester tamps down the smell a bit, but, more importantly, it takes all that cow poop and converts it to electricity.
