Gravity Powered Lighting System For The Poors

Martin Riddiford and Jim Reeves, London based designers, have spent 4 years developing GravityLight as an off-line project. 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.

Martin and Jim believe that this will be a better alternative than solar powered light in replacing kerosene lamps. Solar panels only produce electricity when the sun shines and the energy needs to be stored in a battery to be used at night. However batteries and panels are expensive. Plus batteries have limited lifespan. The high upfront investment and high replacement cost have hindered the spread of solar powered light in underdeveloped and developing countries. GravityLight will be a perfect solution for clean low-cost lighting.

Currently, they are raising fund through Indiegogo to manufacture 1,000 units of the light and will gift the products to villagers in both Africa and India to use regularly. This will tell them how well the lights met the people needs. The data collected will be used to refine the design. The goal is to make GravityLight costs less than $5 when mass produce.
