Abstract
Abstract One or more buoyancy engine units utilizing buoyancy motive force (BMF) are herein defined. For relatively deep fluids a plurality of buckets hinged together mouth to bottom with a gas tight seal between said buckets forming an endless chain can rotate over sprockets attached to parallel shafts spaced apart to control chain tension as either shaft delivers buoyancy motive force (BMF). Each buoyancy engine unit will produce continuous duty rotation and thereby power when the receptacles are alternately filled with gas and then the fluid in which they are submerged.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
196 words
An apparatus for converting the potential energy of a gas buoyant within a liquid into rotating kinetic energy comprising: (a) a housing supporting an upper and lower shaft, said upper and lower shafts immersed within a body of liquid and having at least two upper and lower sprockets mounted respectively on said upper and lower shafts, said lower shaft having an adjusting plate which allows for a vertical adjustment between said upper and lower shafts, (b) an endless chain of buckets attached to one another by hinges, said hinges meshing with said upper and lower sprockets, each of said buckets having a seal attached to its base so that when one bucket is vertically disposed above another adjacent bucket a gas tight seal forms between the base of one bucket and the mouth of the other bucket, (c) means for injecting a gas into the buckets on said lower shaft so that the liquid in the bucket is displaced by the gas and the buoyant force on the bucket causes the bucket to rise through the liquid and rotate the upper and lower shafts, (d) and a power output shaft mechanically connected to said upper shaft.
