Utilizing Earth's Gravity LED Lights to Realize Zero Energy Consumption

Although people in developed regions have already used computers, televisions, and various modern household appliances and digital products, in the less developed regions of the world, there are still 1.5 billion people who need to use kerosene lamp lighting. A product called GravityLight hopes to help people in these areas solve this problem.

GravityLight's developers had previously developed solar-powered led lamps for some African villages. They currently hope to use a different kind of free energy source to generate electricity. This is the gravity of the Earth. Currently, they are raising funds for this project through a crowdfunding platform.

GravityLight is an LED light. Users simply bring up a 9kg bag equipped with GravityLight, which will generate enough energy to achieve 30 minutes of lighting. This LED light does not require rechargeable batteries or energy at all, which means no cost.

GravityLight's design allows it to charge other devices such as radios and rechargeable batteries. These devices can be connected to an interface on the GravityLight front panel. According to the user's needs, or to extend the lighting time, GravityLight's 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 and switch to this new lighting tool. A study by the University of California, Berkeley and the University of Illinois showed that the damage to kerosene lamps on the environment and human health may exceed expectations.

Currently, GravityLight's team is trying to raise $55,000 in funds to manufacture and sell at least 1,000 GravityLights for people in Africa and India. They also plan to improve design and efficiency in actual use.
