POWER GENERATING SYSTEM USING BUOYANCY

摘要

A power generating system using bubble buoyancy is disclosed. The system generates the bubbles in water charged in a sealed housing and operates a rotational force generating unit using the bubble buoyancy to generate the rotational force. The housing may be partitioned into several chambers by means of vertical partitions and provided with at least one rotational force generating unit in each of the chambers. The air, after being used in the first chamber, is reused for generating the bubbles in the second chamber. The rotational force generating units may be vertically arranged in a line in the housing and the bubbles are generated under the lowermost unit. The bubble bucket sizes are different from each other in accordance with unit's positions in the water so that the buckets more reliably capture the bubbles which gradually expand due to water pressure difference according to the depth.
