London-based designers Martin Riddiford and Jim Reeves — from Therefore.com – 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.
