GRAVITYLIGHT
An innovative device that generates light from gravity
GravityLight’s
Mission:
To
provide affordable, sustainable and reliable light, anytime, that enables
people to break free from the economic, health and environmental hazards of
kerosene lamps.
What
is it exactly?
GravityLight
is a gravity-powered light created by the company Deciwatt. It was primarily
invented for use is third-world countries as a replacement for kerosene lamps.
How
does it work?
It
uses a back filled with rocks or earth, which is attached to a chord that
slowly descends. The weight attached to the device must weigh around 20lbs. The
light shines for 30 minutes.
Meet
the inventors!
GravityLight
was created by Martin Riddiford and Jim Reeves. Faced with the question
"How to do more with less?", they were inspired to create
GravityLight, thus empowering people through a sustainable, and affordable
power solution.
