WO1997005380B1 - Device for using centrifugal force for generating energy - Google Patents

Abstract

The object of the invention is to use centrifugal force to produce energy in an environment-friendly, economic manner for driving purposes or for decentralised electric current or heat generation. The figure shows the simplest embodiment of the device. It consists of a rotary aggregate with accumulator (1), switchable motor/generator (3), and a rotary frame (5) with weights (10) that can be moved in the radial direction and that are linked by cables (9a, 9b) to a cable drum (9) arranged at the centre of the rotary frame (5). The device works cyclically. At the beginning of a working cycle, the rotary frame (5) is rotated by the motor (3). When the maximum speed of rotation is reached, a stopping device for the weights (10) is triggered, so that they are projected by the centrifugal force to the periphery of the frame, unwinding the cables (9a, 9b) from the drum (9) that is also rotated together with the rotary frame (5). When the weights (10) are released, the motor (3) is switched to a generator mode in order to convert the energy of rotation of the rotary frame (5) into electric energy. When the rotary frame stops, the generator is switched back to a motor mode. The energy generated by projecting the weights may also be supplied to an additional generator.
