GravityLight Gravity Light: Using Gravity to illuminate


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 developers have previously developed solar LED lights for some villages in Africa, and 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 for this project through a crowdfunding platform.
GravityLight is an LED light. Users only need to bring up a 9 kg bag with GravityLight, then they can generate enough energy to achieve 30 minutes of lighting. This LED light does not require a rechargeable battery or energy at all, which means there is no cost to use.
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. A study by the University of California at Berkeley and the University of Illinois showed that kerosene lamps could damage the environment and human health more than previously expected.
Currently, GravityLight's team is trying to raise $55,000 to build and sell at least 1,000 GravityLight for people in Africa and India. They also plan to improve design and efficiency in actual use.

Nano Coating For Optical Lenses

The surface of the optical glass screen is anti-fingerprinting, has no oily feeling, does not affect the gloss of the metal surface, is convenient to use, and does not need to be cleaned.

Scratch resistant. Optical lens anti-fingerprint coating agent debugging method:

1. Clean the optical glass with alcohol or ultrasonic.

2. Drip the anti-fingerprint oil onto the clean cloth, gently rub it onto the glass, level it for 0.5-1 minutes, enter the oven for 150 minutes and 30 minutes, then wipe off the dust spots on the surface with alcohol, fine lines, you can It is.

3. It is also possible to leave it in the clean room for 30 minutes without baking, and then clean it with ultrasonic alcohol.
