Abstract
A compressed gas buoyancy generator powered by temperature differences in a fluid medium having a thermal gradient which includes a body having an inflatable chamber connected thereto for rendering the body buoyant at a surface of the fluid medium and a mechanism for inflating the inflatable chamber with a gas, the inflating mechanism including a mechanism for inflating the inflatable chamber with the gas by obtaining energy from the thermal gradient within the fluid medium. The inflating mechanism includes a mechanism for absorbing heat at a surface portion of the fluid medium and for converting the absorbed heat at a predetermined depth of the fluid medium into a mechanical work for inflating the inflatable chamber when the body is at the surface of the fluid medium.
