Eco Bike Trailer

Paul Elkins originally designed this bike trailer to get around the Burning Man Festival. There's only space for one, and if you need to use the restroom you'll have to resort to the great outdoors, but it is fully powered by a wind turbine and comes equipped with a solar-powered oven and heating system. (In a space this small, you might not need anything more than your own body heat!)
