ABSTRACT:
A conduit extends from a platform on the surface of the ocean into cold deep ocean water containing dissolved gases. Sufficient water is drawn from the top of the conduit to cause the gas containing cold deep ocean water to enter the lower end of the conduit and release dissolved gas thereby forming a foam which causes the bulk density of the foam to fall. The change in bulk density causes the foam to move upward through the conduit pushing the foam to higher heights in an effort to reach pressure equilibrium inside and outside the conduit at a level of incipient foaming. The moving foam is used to drive a turbine or otherwise provide useful energy.
