ABSTRACT:
A method and apparatus for producing compressed air includes sealing air in a container capable of reducing its volume by external hydraulic pressure. A weight having a larger specific gravity than water is attached to the container to sink the container deep under water. Compressed air is produced when the volume of the container is reduced by hydraulic pressure, and is transferred into a recovery vessel connected to the container via a check valve. The weight is then separated from the container use and cause the container to float on the water by the action of buoyancy. The compressed air can then be recovered from the recovery vessel.
