The crowd farm presents a responsive sub-flooring system that could be placed in a crowded place. It consists of blocks that depress slightly when people step on them. This way the blocks move and rub against one another when people walk on this floor. Thus the electricity is being produce by the principle of dynamo, which converts motion energy into electricity.
Smart, huh? It is almost as good as painting your house with a special solar power absorbing paint that we have also reviewed. However, this one would cost more, but maybe it will also bring more energy.
The best places for such farm would be the malls, transit station and any other area with heavy foot traffic.
