Gravity Light

January 23, 2013

You lift a few rocks within a few seconds and receive clean and green energy for 30 minutes. You don’t need any batteries and you don’t pay anything apart from an initial cost of $10. Sounds unbelievable, but it’s true! An innovative, low-cost lighting solution makes it possible: Gravity Light. Martin Riddiford and Jim Reeves, two London-based designers, have developed a lighting solution based on gravity. The device has two elements: a body with a lamp and a power generation unit consisting of a weight that has to be filled with sand or stones and is then lifted up in the air for a few seconds. By the time the weight returns to its starting position, power has been generated automatically – completely emission free and independent of electricity or solar power. Apart from being a source of light, the device also serves to power other things. On top of that, Gravity Light is a real money-saver because there are no running costs, people can save the money they would have spent on kerosene or other biogas fuels and invest it in more powerful lighting systems, for example solar panels.
