FIELD: production of mechanical rotation energy due to complex use of temperature difference of sea water for various levels, gravitational interaction, and hydrostatic forces. SUBSTANCE: heat sensing elements 4 linked with weights 2 and floats 3 are uniformly placed about circumference of rotor 1 mounted for rotation and immersed in sea water; they function to displace weights and floats in relatively opposite radial directions in response to ambient sea water temperature variations which is ensured due to heating and cooling regions provided on either side of rotor, first one being upper layer surrounding the rotor and second region being formed by chamber 5 communicating through pump 7 with upper part of piping 6 dipped into cool layers closer to sea bottom. Rotor is set in motion by moments of forces F created by weights and floats at different distances R1 and R2 on either side of axis O depending on temperature of heat sensing element. EFFECT: simplified design. 3 cl, 2 dwg
