‘gravitylight’ – gravity powered lighting for developing countries



london based designers martin riddiford and jim reeves have developed the ‘gravitylight’, an innovative new approach to storing energy and creating illumination. taking only three seconds to lift the weight which powers the device, the process creates 30 minutes of light through its descent. the project aims to reach developing countries without access to electricity, where traditionally, kerosene lamps are used for providing luminosity. conceived without batteries, the system works by creating a charge through a ballast that weighs down a pulley, generating the needed energy for power. additionally, the ‘gravitylight’ incorporates an external negative and positive terminals for charging accessories, or batteries if needed.


the ‘gravitylight’ is currently seeking funding on indiegogo.
