At Dancing Rabbit Ecovillage, villagers are always trying out new ways to reduce their impact on the planet. Two of my neighbors, Rae and Aaron, wanted to go on a road trip around the country to help with activism around stopping the use of fossil fuel. It seemed a bit hypocritical to be road tripping on gasoline though, so they built a system from scratch that would allow them to drive on a renewable resource–waste wood. They learned to weld and use a plasma torch, and they built almost everything from waste metal and materials. It’s not a simple system, but they were up for the challenge.
