London-based designers Martin Riddiford and Jim Reeves — from – spent four years developing a light that would provide a viable alternative to kerosene and sun-powered lamps for developing nations. GravityLight works by harnessing the power of weight and gravity, it is easy to run, low-energy, battery free and also, cheaper than solar lighting. Currently raising funds on indiegogo GravityLight’s creators are looking to test and begin mass-production on this innovative design, in the hopes of brightening peoples’ lives when it gets dark.

GravityLight is an important development because 60% of female, adult, non-smokers, are getting lung cancer from inhaling the fumes of commonly-used kerosene lamps. Designed specially for people in Africa and India with no access to mains electricity, the lamp generates enough energy for half an hour of light when holding weight for just a few seconds. With no batteries to run out, replace or dispose of, GravityLight it is complete completely clean and green and the use of LEDs means they don’t attract annoying mosquitoes like conventional bulbs.

    this could b the savior of the future lighting.. can you imagine the money you are going to save if you don\\\’t have regular electrical lights running in your home… I have seen where some people have actually gone with small solar panels to help offset the cost of electric for heating and cooling. electricity could soon become a thing of the past for a lot of homes…

    We are planning to start switching out the single pane windows in our 85 year old fixer-upper. I would also like chickens this year so that we can be a little more sustainable and have our own eggs, plus some bug control help in the vegetable garden!

    great idea and cost efficient! Hoping that 30 minutes will be extended to hours, so I don’t need to reset it from time to time
