(EP541761-A1)      The system (100) includes an electric motor rotated by an outside power supply and a compression device for feeding a fluid forcedly by the motor rotation. A fluid velocity increasing device includes a disk shaped fluid pipe, whereby the fluid flows from the outside or input side of the pipe toward the centre of the velocity increasing device, and then turns about the centre, thus producing centrifugal force.    A turbine generates power from the energy in a stream of fluid discharged from the velocity increasing device and fluid coded by the heat energy taken from the turbine is fed by the compression device. A heat exchanger obtains the taken heat energy from a fluid of normal temp. and re-introduces the fluid into the velocity increasing device. The propulsion device forcedly feeds fluid from one side to another using generated electrical energy. Two pipes having a groove and decreasing section respectively convert the fluid flow to produce a force directed to one side.    ADVANTAGE -   Produces powerful and high speed turning force utilising small amount of energy. Simple in construction and effective in operation. Buoyancy or propulsion may be exhibited independently of outside air.
