This really energy-saving LED lamp using the earth's gravity to achieve zero energy consumption"

Although in developed areas, people have to use the computer, TV, and a variety of modern home appliances and digital products, but in the less developed regions of the world, there are still 1 billion 500 million people need to use kerosene lamps. A product called GravityLight hopes to help people in these areas to solve this problem.

GravityLight's developers had previously developed solar LED lights for a number of villages in Africa, they now want to use a different kind of free energy to generate electricity, which is the gravity of the earth. Currently, they are raising funds through the platform to raise funds for this project.

GravityLight is a LED lamp. As long as the user with a GravityLight with 9 kg of the bag, then you can generate enough energy to achieve the lighting for 30 minutes. The LED lamp does not need to charge the battery or energy, which means no cost.

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

GravityLight's team hopes to reduce the price of this product to less than $5, which will attract people in poor areas to abandon kerosene lamps, switch to this new lighting tools. A study by the University of California at Berkeley and the University of Illinois shows that the damage to the environment and human health may be greater than previously expected.

Currently, GravityLight's team is trying to raise $55 thousand to build and sell at least 1000 GravityLight to people in Africa and India. They also plan to improve design and efficiency in practical use.
