METHOD AND APPARATUS FOR GENERATING ELECTRICAL ENERGY FROM UNDERWATER FALLS
Electrical energy is generating by submerging a tank in a body of water so that its water inlet is located under a water surface and covered by water and water flows into an interior of the tank, evacuating water from the tank by an evacuating element through a water outlet of the tank to maintain in the interior of the tank a space for flowing water through the inlet into the interior of the tank, arranging a converting element which convert energy of the water flowing into the interior of the tank into an electrical energy, and the evacuating element operates independently of an operation of the converting element.
