Gravity light

Post by Dreamweaver » 13 May 2015, 16:48

According to the International Energy Agency, more than 1.3 billion people -- 18% of the global population -- lack access to electricity, the majority of whom rely on kerosene for lighting.

The GravityLight offers a safer alternative, offering light through energy generated by the weight of a small bag filled with rocks, sand or soil. User trials are still being conducted in the field, but the GravityLight is expected commercially later in 2015
