The new covering for a floor is loaded with energy of steps

It is necessary to advance on the way to renewable energy with gigantic strides. In literal sense. Scientists from University State of Wisconsin and Forest Products Laboratory in Madison consider that can use mechanical energy of human steps by means of a usual floor covering. They suggest to use chemically processed nanofibres of cellulose in wood cellulose which make electric a charge, coming into contact with the raw nanofibres.
