FIELD: power engineering. SUBSTANCE: method consists in making use of gravitational engine which has hollow hub 2 mounted on shaft; mounted on outer surface of this hub in radial position are solid members made in two versions: in form of flexible bellows whose elasticity works in compression or in form of cylinders 15 with pistons 16; pistons of diametrically opposite cylinders are connected by means of rods. Secured on external sides of bellows and on pistons are massive weights. Transformation of gravitational forces acting on weights 4 to rotational energy of shaft is effected due to position of weights which changes continuously relative to axis 0-0 of rotation through acting on solid members located on one side from vertical plane passing through axis of rotation 0-0 by working medium having excessive pressure as compared with surrounding medium. EFFECT: enhanced efficiency. 5 cl, 4 dwg
