that with a 26lb (12kg) weight it is possible to provide between 25 minutes of light if installed at a height of six feet (1.8 metres). They are also working with a factory in Kenya to begin producing the lights. The device means families can replace their dangerous kerosene lamps that are common in many parts of the world to light activities after dark. These lamps use naked flames and can produce harmful fumes. 'It costs nothing to run, doesn't need batteries and pays for itself within weeks of switching from kerosene.'. The scientists behind the 'pee-power' toilet hope it can be used by aid agencies in disaster zones to supply much-needed electricity to refugee camps. The GravityLight is aimed at helping the.3 billion people who live without electricity in areas of the world too remote or poor to have a reliable grid. Scroll down for video, the GravityLight (illustrated above) uses a weighted bag which is attached to a hook to power a generator. HOW THE gravitylight works, the device is installed to the ceiling of a room and a bag filled with around 26ft (12kg) of rocks or sand is attached to a cord that runs through the unit.

'For families living on just a few dollars a day, kerosene lamps can consume up to 30 of their income creating an ongoing poverty trap. The energy produced can be used to power the light and other devices attached to a DC power outlet. A system of gears and a generator inside the device convert the kinetic energy released by the bag as it falls under the influence of gravity into electricity. Jim Reeves and Martin Riddiford, who are based in London, invented the device. Satellite lamps (like the one above) can be attached to provide vital reading light for children doing homework. Designers claim that utsw secondary essay bullet points when set up, the GravityLight can provide an almost limitless supply of light in homes. According to Mr Riddiford: 'GravityLight is a low cost, safe and reliable alternative to the kerosene lamp. The generator produces just under a tenth of a watt which powers an LED light on the unit itself and two smaller satellite lights that can be hung over a desk or bed. Once the bag reaches the ground it can be raised back up to the ceiling to produce more power. This produces a tenth of a watt - enough to power an LED light and two smaller lights. Prototypes of the GravityLight have been tested in around 1,300 homes, like above, in 27 different countries.
