GravityLight

GravityLight is a revolutionary and sustainable new approach to creating energy and generating light from an LED lamp. GravityLight can potentially eliminate the need for kerosene lamps, with huge environmental and economic benefits. It takes only 3 seconds to lift the weight that charges GravityLight, creating 30 minutes of constant light, as the weight drops under the force of gravity. GravityLight has no batteries to run out, replace or dispose of, and has no reliance on the external environment, time of day, season or weather.
