Clean Energy from Waves

Clean Energy from Waves uses of a high-pressure system to move the turbine and the generator, a concept that was developed and patented by Coppe. The whole set consists of a buoy and a mechanical arm. When the waves move the buoy and the mechanical arm, they drive a pump to pressurize fresh water and store it in an accumulator connected to a hyperbaric chamber. The pressure in the chamber is equivalent to that of water columns found at hydropower plants.
