Abstract

PURPOSE: To generate electric power economically and without causing environmental pollution, by producing a current of fluid in water passages through utilization of differential pressure produced at the back of a weir, and turning power generating water turbines by the force of the current of fluid.
CONSTITUTION: In applying the principle of this invention to a ship, a proper number of water tanks 2 are formed in the body 1 of the ship, and sea water is introduced from respective sea water inlet parts 3 into the water tanks 2 to the level of waterline l. When the ship 1 starts to travel, a relative velocity difference is produced between the ship and sea water, so that virtual flow of fluid L is produced. Here, if a weir plate 10 is fixed at the front of each opening 5' formed in the bottom of the ship 1, water in the tanks 2 is drawn from outlet ports 5 to the outside of the ship 1 since vacuum is produced at the back of weir plates 10. That is, a current of sea water through the outlet ports 5 is produced, which serves to turn runners 8 of water turbines 6 and hence generators G. Although sea water is discharged from the ports 5 to the outside of the ship, corresponding amount of sea water is supplied into the tanks 2 from inlet ports 3.
