New LED light GravityLight helps poor areas solve lighting problems

Although computers, televisions, and a wide variety of modern home appliances and digital products have been used in developed regions, there are still 1.5 billion people in the less developed regions of the world who need to use kerosene lighting. A product called GravityLight wants to help people in these areas solve this problem.

GravityLight is a solar LED light. The design team hopes to use a different kind of free energy to generate electricity, which is the gravity of the Earth. Users only need to bring up a 9 kg bag with GravityLight to generate enough energy for 30 minutes of lighting. This LED light does not require a rechargeable battery or energy source at all.

GravityLight is designed to charge other devices such as radios and rechargeable batteries. These devices can be connected to an interface on the GravityLight front panel. The brightness of GravityLight can be adjusted according to the needs of the user or to extend the lighting time.

GravityLight's team hopes to reduce the price of the product to less than $5, which will attract people in poor areas to abandon kerosene lamps and switch to the new lighting tools.
