In order to a certain lifting forces to be able to produce more energy has hitherto had to be used as the energy could be obtained therefrom. Because of the physical or technical efficiency was a regenerative power generation means lifting forces which has not been possible heretofore.By the use of heat pumps, physical properties of a high pressure cold by means of (such as, for example, co2) are made use, in that both the evaporator - as well as the liquefaction energy of a heat pump be used, for example, to pressure - and volume differences of the gas under the surface of the water and to obtain to generate buoyancy forces. A plurality of heat-transferring medium pumps units are installed in a so-called paternoster-type lift, which can be connected via the buoyancy forces is set in rotation.The device, in offshore - platforms, as well as in deep holes, or for use in taverns.
