Adequate lighting is still a problem for over a billion people around the world. In many instances, villagers must use kerosene or even wood just for simple lighting, an expensive and unhealthy option.
Therefore Products wanted to fix this problem, and has created the GravityLight.
The inventive light requires no fuel or alternative power source. Simply pick up the weight that is attached to the small light and let it go.
As gravity pulls the bag of weight down, a small generator is turned to power the light, offering up to 30 minutes of light for literally three seconds of work. That is, picking up the weight.
Incredibly, their relatively new crowd sourcing campaign on IndieGoGo already has nearly $300,000 worth of contributions, well over their $55,000 goal.
