How cool is this?
A design firm in Milan, DesignLibero, has given the concept (reportedly inspired by a NASA prototype) a redesign with its Green Wheel, a small table-sized version. The Wheel is intended to grow fresh greens all year round in urban homes. A small engine sends plants on an infinite circular orbit around a light source at the center, and the plants take root in coconut husk fiber. A dousing of water keeps the plants alive each time it passes the reservoir in the base.
