The gas is compressed by disposing one or more hydrofoils in a liquid flow for the purpose of generating a downpull and thereafter a lift by altering the angle of attack on the hydrofoil relative to the flow of liquid, advantageously water.

The angle of attack of the hydrofoil is altered by mechanical devices connected to tension bars or strings or by flaps. The volume of air loaded in the hydrofoil is adapted such that the down force is greater than the buoyancy of the air.

At arrival on the intended depth, the volume of the compressed gas is pressure locked. The hydrofoil is disposed to a unload station on the surface, or under water by altering the angle of attack of the hydrofoil, after which the compressed air is unloaded and conveyed further for utilization for energy purposes. | 07-26-2012 |
