Patent ID: 7513733

Claim:
An apparatus for energy production in the form of a torque, comprising: at least two deflection elements, which are arranged aligned with one another, an endless, chain-like coupling element on which at least two buoyant bodies are arranged, and a vertically aligned, liquid-filled container with an inlet opening, which is formed on its end face facing the ground, as well as a sealing element which prevents the liquid from emerging, with the buoyant bodies describing a revolving movement about the deflection elements and the buoyant bodies, which move against the force of gravity, passing the liquid-filled container through the inlet opening wherein said buoyant bodies are elastic; the cross section of the inlet opening of said liquid-filled container is smaller than the cross section of an elastic buoyant body in the unloaded state; said buoyant bodies form a fluid-filled hollow body; and the apparatus has at least two elastic buoyant bodies, whose fluids are connected to one another.
