Scientists invented glass, receiving energy from the wind and rain

A team of researchers at the Georgia Institute of Technology придумали glass , which can produce electricity. However, energy is produced not by fotovoltatsii, although indirectly it is associated with the sun. Glass produces electricity due to the typical weather resistant - rain and wind, and трибоэлектрическому effect .

The outer layer of the multilayer glass "pie" interacts with raindrops, producing a positive charge from the friction of the air on the way to the ground. On the surface layer are pyramid height of about 5 nm, creating a hydrophobic effect. Falling on the surface of the outer layer, positively charged droplets having a same kinetic energy makes the structure small electrical charge.

The second layer comprises two thin sheets of plastic, which are kept at a distance mikropruzhinami. The impact of wind pushes the layers to each other, and thus through the triboelectric effect also produces electricity.

Collaboration of all layers of the material gives a capacity of about 130 MW. Now, researchers are looking for ways to save the received energy - for example, through transparent supercapacitors, which also can be incorporated into a transparent structure.

Scientists of the Institute have long been working with materials that produce energy on the basis of the triboelectric effect. In 2013, they experimented with electric working on the same principle that in the future can be built into the sole of the shoe to charge Gadgets on the go, or floor coverings.

The effect is haunted and other inventors. Someone is trying to make pectoral electricity generator , and someone - even collect in this way энергию waves.
