GravityLight is a revolutionary new approach to storing energy and creating illumination. It takes only 3 seconds to lift the weight which powers GravityLight, creating 30 minutes of light on its descent. For free.

GravityLight set a modest goal of $50,000, Deciwatt raised an eye-opening $400,000 on the crowd-sourcing site Indiegogo.
