Abstract: A device for converting gravitational force to energy. The device comprises a rotor (1). The rotor comprises a first outer chamber (4), a second outer chamber (5), and a casing (40). A piston (3) is slidably received in the casing between the first outer chamber (4) and the second outer chamber (5), above the first outer chamber. When the piston slides in the casing towards the first outer chamber, displacement fluid (7) exits the first outer chamber and enters the second outer chamber, thereby causing the second outer chamber to be heavier than the first outer chamber. A pivot (12) is provided wherein the rotor (1) can rotate such that the second outer chamber becomes lower than the first outer chamber. A shaft (14) is provided which is parallel to the pivot and capable of rotating with the rotor. A generator (15) is coupled to the shaft.

Abstract: A device for converting gravitational force to energy. The device comprises a rotor. The rotor comprises an upper portion, a lower portion and a casing. A lower cavity and an upper cavity are provided in flow communication with each other. A piston is slidably received in the casing between the lower cavity and the upper cavity. When the piston slides in the casing towards the lower cavity displacement fluid exits the lower cavity and enters the upper cavity thereby causing the upper portion to be heavier than the lower portion. A pivot is provided wherein the rotor can rotate such that the upper portion becomes lower than the lower portion. A shaft is provided which is parallel to the pivot and capable of rotating with the rotor. A generator is coupled.
