“GravityLight” a device that uses gravity to generate energy off the grid and could be a source of cheap light in developing markets.”

The gravity-powered lamp is an answer for the estimated 1.5 billion people with no access to electricity worldwide and it could replace the biomass fuels – mainly kerosene lamps – which so many families in the developing world rely on for light.

The light was developed by London start-up Deciwatt. Using a 12kg bag threaded through a patented electricity-generating device to power a small light, the technology generates safe light with no risk of burns, house fires or kerosene-related illnesses.
