A fluid, for example, air, is subjected to a high pressure while in a high pressure inducing vessel (101). The high pressure is due to a large mass, such as the ocean. The fluid is then cooled and directed into a depressurized vessel (107), such as a pressure hull, which is at a relatively lower pre

A fluid, for example, air, is subjected to a high pressure while in a high pressure inducing vessel (101). The high pressure is due to a large mass, such as the ocean. The fluid is then cooled and directed into a depressurized vessel (107), such as a pressure hull, which is at a relatively lower pressure. With this change in pressure, the fluid expands. This expansion is used to generate work/energy using a work producing machine (108), for example, a turbine. Energy from the work producing machine is converted to electricity using a generator (111). The fluid is collected from the work producing machine and again subjected to the high pressure and low pressure to generate additional electricity.
