Gravity Lamp

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. It can be used over and over again with no running costs.


This brilliant solution for lighting off-grid homes (initially designed as a replacement to kerosene lamps in rural Africa) uses one of the most overlooked but abundant resources on Earth: gravity!

After large-scale manufacturing, a GravityLight unit will cost less than $5 each. Brilliant!
