Patent ID: 8813488

Claim:
A system for generating power, the system comprising: a gas compressor; a reservoir for storing compressed gas; and an apparatus adapted to be located within the body of a liquid, the apparatus comprising at least one chamber in fluid communication with the compressed gas reservoir and an output device, wherein the at least one chamber is fixed to a rotor rotatable about an output shaft, wherein, in use, a compressed gas is supplied to the at least one chamber from the reservoir, the buoyancy of the gas applying an upward force to a portion of the at least one chamber, the upward force moving at least a portion of the at least one chamber from a first position to a second position, the movement of the at least a portion of the at least one chamber adapted to drive the output device to provide a continuous apparatus output, wherein the at least one chamber includes an inlet and an outlet, the inlet and outlet being separate, wherein the inlet has at least one valve adapted to open when the at least one chamber is in the first position and permit the supply of a volume of compressed gas into the at least one chamber, wherein the apparatus comprises a valve actuator to actuate the/each valve when the at least one chamber is in the first position, wherein the at least one chamber defines a volume, the gas, in use, occupying up to 90% of the volume of the at least one chamber prior to reaching an intermediate position wherein expulsion of the gas commences through the outlet, the intermediate position being between the first position and the second position, and wherein as the gas expands in the at least one chamber, the gas absorbs heat from the body of the liquid.
