Abstract: Disclosed is a submerged power generation system. The system may include a hollow fluid flow column, substantially parallel with the direction of gravitational acceleration, a fluid inlet, and a fluid power generator in the hollow fluid column. The system may further include fluid outlets and a pump system at the end of the fluid column opposite from the inlet. Further, an electrical distribution cable or power distribution system in communication with said fluid power generator may also be integrated into the system. Various other power storage, generation, and distribution systems may be integrated into the system to further enhance the efficiency and capabilities of the hydroelectric power generation system.

Abstract: Apparatus and methods for isolating and absorbing energy associated with shock forces that are exerted upon an object, such as the energy attendant to shock forces experienced during and immediately following a mild to severe impact. The apparatus generally having: (a) a housing defining an enclosure; (b) at least one segment of non-liquid material contained within the enclosure; and (c) a piston placed within the enclosure. When the shock or impact force is applied to either the piston or housing, the piston urges the non-liquid material to pass or extrude through an aperture, orifice, channel or slot located either within the piston or the housing. The non-liquid material passes or extrudes through the aperture, orifice, channel or slot in a direction that is generally transverse to the relative movement of the piston within the enclosure.
