A negative energy power supply which operates submerged equipment like a hydraulic actuator. A main component of the system is a submerged chamber held at substantially atmospheric pressure. It is connected to submerged equipment having intake and discharge ports controllable by remotely operated valves. When the intake port is opened to water at the submerged depth of the equipment and the discharge port is vented to the chamber, the resulting pressure difference operates the submerged equipment. The system can also have appropriately connected to it, a pressure amplifier to increase the water pressure at a submerged location and a pump to purge the chamber. |
