GravityLight™ is an innovative device that generates light from gravity.
It takes only 3 seconds to lift the weight that powers GravityLight creating 25 minutes of light on its descent.
By using a weight that is lifted by the user, the device is powered by the controlled descent of the weight which turns a dynamo.
Because of its ability to generate a current in a completely isolated, internal space; and because of its need to be manually managed / re-wound it could be an interesting side-feature of an art-piece that has an eco-theme and a social element (the social element could be explored as a type of game that uses the crowd to win the device.)
For these reasons I am recording this device, for possible future reference.
