Mentioned lights, we inevitably think of power, a very close relationship between the two, even though we now use LED lights or need to pass the charge force to support, but all this? The answer is no, the latest scientific and technological achievements which there is an application of gravity to provide energy LED lights.
A few days ago, the British developed the LED the gravitational lights (GravityLight) to solve the problem of lack of electricity supply area lighting.
The gravity lamp LED light, users only need to raise a weight of 20 pounds (9 kg) bags, you can let gravity lights work continuously for 30 minutes. Gravity lights completely without charging a battery or other energy, which means that it does not work when costly.
In addition, the lighting unit charging for other equipment, such as a radio or a rechargeable battery, only the device connected to the interface of gravity lamp. The user can be required to adjust the gravity brightness of the lamp illumination time to be extended accordingly.
For this requires only the gravity design unit will be able to provide a certain energy, or will our future power development process to provide a new reference ideas, after all, the distinguishes this production production of electricity from conventional electricity, will not produce a large number of pollutants.
