More than a billion families lose the ability to light up their homes the moment the sun sets.

Unfortunately, the necessity of kerosene lanterns poses very real health and safety risks while burdening the family with huge fuel costs.

The good news is two British scientists have set out to change all of using only rocks.

The GravityLight is a simple pulley system that once loaded up with rocks or dirt can power a mini generator creating enough power to light a room.

This breakthrough aims to end third world reliance on inefficient light sources while bolstering economic productivity and cutting pollution.

GravityLight will be taking the weight of energy poverty and off of countless of families around the world.
