Abstract: A system for the distillation of sea water comprising a sea water input conduit, an evaporator, a work extractor, a float, a condenser, a distilled water output conduit, and a brine solution output conduit. The evaporator is connected to the input conduit. The work extractor comprises a cylinder, a piston slideably engaging the interior of the cylinder, and a piston rod extending from the piston. The piston rod is pivotally coupled to the float. The cylinder is pivotally attached to a second float. The second float is connected to the first float. A conduit connects the piston-and-cylinder arrangement with the condenser. The condenser communicates with the distilled water output conduit. The evaporator communicates with the brine solution output conduit. The energy for this system is provided by the wave motion of a body of water.

Abstract: A work extracting device driven by the wave motion of a fluid comprising a first float, a cylinder, a piston slidably engaging the interior of the cylinder, a piston rod extending from the piston and pivotally coupled to the first float, and a second float connected to the first float. The first float has a density suitable for floating and moves in response to wave motion. The cylinder is pivotally mounted to the second float. The first and second floats are part of a Hagen array of floats. The first float has an arm extending a distance beyond the point of connection of the first and second floats. The piston rod is pivotally mounted generally about the end of the arm.

Abstract: The present invention is an apparatus and surgical procedure method, which together comprise a medical prosthesis to mimic the erectile response of the adult human male.

Abstract: The preferred embodiment of the invention is a wave powered generator including a "Hagen" float array comprising a plurality of floats each of which is coupled to a subsea support structure through a nonlinear power extraction means. The array may be moved below the surface to avoid adverse sea states. Individual array elements are sized and positioned on the support structure to permit fluid coupling of reflected wave energy between the floats.

Abstract: Apparatus for extracting energy from fluid motion, i.e. waves, comprising spacing a plurality of floating modules, which may be single floats or arrays, on the fluid's surface far enough apart to minimize apparatus cost and close enough together to utilize the vortex-like action of the waves to extract a maximum amount of wave energy. This spacing is preferably about half the wavelength of the incident waves. The energy extracted by the modules is converted to hydraulic, electrical, mechanical, or chemical energy.

Abstract: The invention is an efficient hydraulic motor/pump whose mechanical advantage can be varied while it is operating. Preferred embodiments described include a multi-cylinder reciprocation motor/pump, a variable level power extraction system used with a wave generator, a hydraulic transformer and a hydraulic autotransformer.

Abstract: A plurality of different sized floats are connected into an array through nonlinear interfaces so their relative motions drive hydraulic pumping means. Floats in the array are sized to present a "black body" to the ocean waves incident upon the array. Fluid moved by the pumping means is used to drive an electric turbogenerator.
