Gravity + Rocks = LIGHT

We want to share with you an incredible new gadget from a company called Deciwatt, they’re the 2015 winner of Shell’s Springboard programme and it’s called GravityLight. GravityLight is a gravity powered lamp which uses the earth’s gravitational pull to create light. How? Here’s how:

A bag of rocks is attached to the light via a strap, then as they fall to the earth the strap pulls on some gears which then drives an electric generator which powers a bright LED bulb and the gravitational pull is able to give continuous light for 20minutes. The beauty of this device? It will never run out of battery and the bulb will last a VERY long time. The device is aimed at combatting the energy expense in the developing worlds and as there are no running costs of these lights, the only payment is for the purchase of GravityLight and then it will last for years.

The reason for GravityLight? The ability to provide easy light to those that need it most in places such as Kenya. Following a second successful spell with crowdfunding the GravityLight foundation is now on a 50 Night Tour across 50 Villages in Kenya. What’s really great about this is that people in these villages regularly use a harmful lamp called Kerosene, with the GravityLight it provides safe and clean energy to the people of Kenya.
