Video: Light Powered by Gravity Now Available, Costs Zero to Run

Many people living off-grid use kerosene lamps for cooking and lighting. While this can be cheap, the environmental and health hazards are considerable.

"Kerosene contributes three percent to global CO2 emissions, which is not an insignificant number, and produces indoor fumes, which has been shown to cause 600,000 preventable deaths on a yearly basis in Africa alone," Osibo said.

"GravityLight was invented by two designers looking for a safe alternative to kerosene lamps, which are used by over a billion people without electricity," Caroline Angus, co-founder of the GravityLight Foundation, said.
