This was my favorite discovery in farming without a drop of fossil fuels, and using tons of food waste. Here is the coolest thing ever. A pig pen that moves along a garden bed where pigs eat the grass, sod and till up the soil. By moving this pen a few times a day I can convert food waste to Bacon, Pork chops and Hams! Save $30,000 on a tractor and reduce the ammount of fossil fuel usage by 100%. And this is the tastiest porkey goodness ever!
