GravityLight: lamp $ 5, running on gravity Bashny.Net

Engineers from London company Therefore constructed a working prototype light bulb, which operates on the force of gravity. Enough to hang the bag device with ballast or any other cargo weighing about 10 kg — and the LEDs will glow for about 30 minutes. The idea is that inside the box was a device like weight lifting mechanism that provides the rotation of the wheels with a constant velocity, as in a conventional wall-mounted mechanical clock with weights. That's probably where the generator coil rotates in a magnetic field creates alternating current supplying the bulb.



Lamp GravityLight already collected on crowdfunding site Indiegogo about $317 thousand, almost six times the original pay plan.
Bulbs GravityLight offered to put in Africa, India and South America. In these parts of the world more than 1.5 billion people live without electricity, using kerosene for lighting lamps.

GravityLight is positioned as a more reasonable replacement for the kerosene stove. In some areas, residents give from 10% to 20% of their income on buying kerosene. In India alone, in the hospital annually receives 2.5 million people with burns from kerosene, and the evening with a kerosene lamp is comparable to the inhalation of smoke from two packs of cigarettes, so many people even non-smokers suffer from lung cancer.

The bulb in gravity are mostly in front of solar panels that need to be set in well-lit areas and additionally equipped with batteries for storing the charge to illuminate the evening and at night. Here everything is simple. Raised for three seconds desyatiballnoy the bag — and the light bulb shines half an hour. Instead of a bag, you can use some decorative elements such as stones or vases of flowers. This lamp can be hung even in a dark basement, unlike solar cells.



The developers of Therefore — not some Amateurs, and experienced professionals who have 20 years of design and design different devices. They are well aware that cost 5 $ will be obtained only when the mass production, and therefore offer to Finance the initial run of 1000 copies that will be sent for testing in Indian and African villages. According to the results of the test will be developed by a more convenient version of the device and accessories.



Probably, this lamp would be a good gift not only for Africa and India, but also for residents of Russia, Europe and the United States. Still pretty original gadget, which no one of the neighbors. Besides, it really is cheaper, more efficient and more environmentally friendly than conventional solar panels. And if you do well for weights of 10-20 meters, then the light can Shine and the whole day, and even more.
