Gravity Light – Another Source of Alternative Energy for the Developing Countries!

gravity-light

Gravity Light is a progressive new approach in the field of storing energy and creating illumination. With only the lift of a circa 10 kg bag of ballast (stone, sand or water – anything heavy) up to the device’s base, the weight falls, pulled by the gravity, in a period of 30 minutes and pulls a strap that spins gears and moves a motor that constantly powers a LED. For free. It takes only 3 seconds until the light begin to shine and it lasts for 30 minutes. It has no batteries to replace or run out, it is altogether green, clean and environmentally friendly.

The Gravity Light was designed with the intention to replace the dangerous and polluting kerosene lamps. These lamps are widely used in the developing countries, particularly where there’s no electricity. In the World, there are currently over 1.5 billion people who have no stable access to main electricity and they rely on biomass fuels (mainly kerosene) for lightning when the sun goes down. As a result, according to the estimation of the World Bank, 780 million women and children breathe in smoke that is equivalent to the same quantity of 2 packets of cigarettes daily. 60% of the female victims of lung-cancer in the developing world are non-smokers. The fumes also can cause cataracts and eye infections, and not to talk about the danger of the burning kerosene from which suffer circa 2.5 million people a year, especially in India, from overturned kerosene lamp. Furthermore, not to mention the financial burden: kerosene can consume 10 to 20% of the household’s income just for lightning.

The designers, Martin Riddiford and Jim Reeves from London, led from the Deciwatt (product development initiative with a mission to explore how ‘to do more with less’) with the charity SolarAid spent 4 years developing this product as an off-line project, working regularly for therefore.com.

They were asked to build a light for less than $10, and the final product is the Gravity Light which final price can be even lower. The products should start be used in the beginning of 2014 in the developing countries, but the product has also captured the fantasy of the Western hobbyists.
I’m very glad that there are projects like this one, that are focused to help poor people and at the same time contribute saving our planet. We should encourage this kind of projects, if you are interested in contributing in this project in some way you can do it writing on this e-mail: info@gravitylight.org
