BUBBLE BUOYANCY TYPE PROPULSION METHOD, DEVICE THEREFOR, AND BUBBLE BUOYANCY TYPE POWER SHIP

摘要

PROBLEM TO BE SOLVED: To obtain low-cost, efficient propulsive force and pollution-free, clean ship power without needing an engine of high horsepower. ;SOLUTION: Bubbles once discharged in the water from a nozzle 12 disposed at the ship bottom are guided to the bubble water turbine 3 side at the stern while making the bubbles collide again with an inclined face part 14 or a recessed curved face part 15 formed at a ship bottom part, and the bubble water turbine 3 is rotated through the buoyancy of the bubbles so as to rotatory- drive a paddling water turbines 2 installed on both sides of the stern, thus generating propulsive power. Bubbles are additionally generated again at the ship bottom part through the turning force of the bubble water turbine 3.;COPYRIGHT: (C)1999,JPO
