London-based designers - Martin Riddiford and Jim Reeves have developed a revolutionary lamp that works solely on the power of gravity. A realistic alternative to Kerosene lamps, the GravityLight has the potential to become a sustainable lighting solution for developing countries and even an energy-saving resource for more technologically-advanced nations. It takes only 3 seconds to recharge, or lift the weight back to the original position, which powers the GravityLight, creating 30 minutes of light on its descent. The GravitiyLight’s power source comes from a durable mesh bag, that users fill with rocks and other heavy materials to weigh it down. Best of all, the light can be adapted to power other electronics as well, such as a radio and battery charger. GravityLight itself has no batteries to run out, replace or dispose of, creating a completely clean and green alternative to lighting.
Currently, the team is raising money via Indiegogo to get ready for production. All donations made will go towards the tooling, manufacture and distribution of at least 1000 gravity powered lights, which will then be gifted to villagers in both Africa and India to use regularly. The team is also looking to link with NGOs and partners to distribute it as widely as possible. Check out this innovative lighting project in the video below.
