Kerosene fumes are dangerous. The World Bank believes 780 children and women inhale smoke, which is essentially the equivalent of smoking 2 packs of cigarettes every single day. In fact, in developing nations, over 60% of adult female lung cancer victims are non-smokers. 2.5 million people a year are burned severely from overturned kerosene lamps.
In addition, the financial burden is considerable since using only kerosene for lighting can consume up to 20% of a household’s income. And last, but not least, kerosene consumption produces over 244 million tonnes of carbon dioxide each year.
Enter GravityLight. Martin Riddiford and Jim Reeves, the London-based designers responsible for the invention, have created a unique, clean, inexpensive, and safe light source. GravityLight takes only 3 seconds to lift a weight that powers the device, which then creates 30 minutes of light on descent, for free. There are no batteries to buy, replace, or dispose. The light is 100% green.
The initial cost of the GravityLight is low, about $10, and according to the inventors it pays for itself within three months and allows people to save money thereafter since they will not be buying expensive kerosene. Another bonus: LED bulbs do not attract mosquitos like conventional bulbs, a huge benefit in countries that battle mosquitoes and mosquito-borne illnesses.
