Too much province! LED lamp cost less than 30 yuan can generate electricity by gravity

Tencent Telecom, if you do not have the opportunity to see, some people may not realize that there are still 1 billion 100 million people do not have electricity. This means that when the night comes, they will not be able to provide light through the light bulb. Thus, these families can only rely on burning to get the light at night. Of course, most of these families need to rely on kerosene to burn. In addition to the high cost of burning kerosene, along with environmental pollution, over time will lead to very serious health problems.

Now, designers from London Jim Reeves and Martin Reddiford have developed a lighting solution specifically for families in developing countries. The program is cheap and different from traditional power outlets and expensive solar power. This is called the GravityLight LED lights do not need to charge the power supply, but also means no cost.

The GravityLight is equipped with several pulleys and carefully designed power systems. At the same time with the style of the back of the balance wheel, using gravity to generate electricity. The entire power generation process of GravityLight is such that the counterweight is referred to the air, and then converted into electrical power by the power obtained. It can slow down, take 30 minutes of luminous energy, due to the lack of electricity, the initial investment is almost zero, will not produce garbage.

At the same time, this GravityLight can even be able to charge other devices. Need to recharge the device can be connected to the GravityLight front panel on an interface. You can even adjust the brightness of the GravityLight bulb according to the different needs of users, so as to prolong the service time.

It is reported that the cost of this GravityLight bulbs less than $5 (about 31 yuan). There is no doubt that this GravityLight bulb once officially come out, its low price and simple operation, will attract a lot of consumers.
