Healthier and cheaper than kerosene and less expensive than solar, the GravityLight offers an innovative solution for citizens of developing countries who don't have the luxury of electricity grids to rely on.
Powered by gravity, it just requires a bag of rocks or sand. The attached weight takes only three seconds to lift, but provides 30 minutes of light as it descends.
The Indiegogo campaign has raised nearly $400,000, blowing away the original $55,000 goal. Supporters can sponsor the delivery of GravityLights to villagers in need, plus receive a light of their own, and there's a corporate option for businesses keen to brand the GravityLight with their names.
