Charge the gadget without taking it out of his pocket.
Scientists from the Georgia Institute of Technology have developed a fabric that generates electricity from wind and solar energy.
The researchers used industrial method by which managed to combine solar cells made out of ultralight polymers, so-called trebovaniyami, generating current at the contact of metals with insulators.
According to scientists the application range of fabric is very large. The fabric is quite flexible, it breathes, easy and applicable for different purposes, say the authors of the invention. In one experiment, a piece of cloth protruding from the window of a moving car. Charged household 2мкФ capacitor to a voltage 2 V.
