Abstract: A submerged energy storage system and method incorporates a pump having a helix screw coupled with a storage tank on the sea floor and motive means, such as wind driven impellers or wave motion produced by sliding buoys or driving the screw of the pump.

Abstract: A wave power generator is characterized by an elongate inner member extending vertically in a body of water with its lower end constrained against vertical movement beneath the surface of the water, and an elongate outer flotation member mounted for linear movement along the length of the inner member in response to wave action. The outer member moves along the inner member with the length of the outer member extending along the length of the inner member. Movement of the outer member relative to and along the inner member effects relative linear movement between a coil and magnet to generate electrical power. The wave power generators may be used to supply electrical power to deep water hydrogen generators in which water is electrolyzed at great depths underwater to generate compressed hydrogen gas.

Abstract: A wave power generator comprises an air bellows that is longitudinally expandible and contractible in response to the rise and fall of a flotation member subjected to wave action and to which the air bellows is attached. Expansion and contraction of the air bellows causes air to flow into and out of the air bellows, and the flow of air rotates a turbine generator to generate electrical power. Other wave power generators utilize wave action to effect relative linear movement between a coil and magnet to generate electrical power. The wave power generators may be used to supply electrical power to deep water hydrogen generators in which water is electrolyzed at great depths underwater to generate compressed hydrogen gas.

Abstract: An electric propulsion system includes a first tube fixedly secured to a hull of a boat and having an upper end adjacent an opening in a surface of the boat and a lower end adjacent an opening in the hull. A second tube is concentrically disposed in the first tube and is withdrawable from the first tube via the upper end. An electric drive motor is disposed within the second tube and is longitudinally movable therein between upper and lower positions. The drive motor has a rotatable output shaft coupled with a propulsion unit that is longitudinally movable with the drive motor between extended and retracted positions. When the drive motor is in the upper position, the propulsion unit is in a retracted position within the second tube. When the drive motor is in the lower position, the propulsion unit is disposed externally of the hull and the lower end of the first tube. The propulsion unit includes a blade assembly rotatably driven by the drive motor to provide propulsion.

Abstract: An improved exercise device including two exercise poles, each having an upper segment secured via an articulating joint to the upper body and a lower segment which is slidably connected to the upper segment. The lower segment includes a hand support or hand grip. A vest with an integral harness includes left and right side articulating joints providing a selected amount of friction. Preferably, each joint includes a cylindrical molded hub with two opposed transversely projecting bayonet lugs; the hub is received within a collar affixed at the proximal end of an upper pole segment and having a circular aperture ringed by an inwardly projecting annular flange with two opposed grooves adapted to receive the two hub bayonet lugs. The hub and collar are separable and are joined by aligning the hub bayonet lugs with the collar flange grooves whereupon the hub may be inserted coaxially within the collar, thereby projecting the hub lugs beyond the opposing surface of the inwardly projecting annular flange.

Abstract: An exercise device including an upper segment secured via an articulating joint to the upper body or arm and a lower segment which is slidably connected to the upper segment. The lower segment includes a hand support or hand grip. The attachment of the upper segment to the body is done via an articulating joint so that the upper segment may be freely moved in an arc of approximately sixty degrees, front to back. The joint provides a selectable amount of friction, thereby enhancing the intensity of the exercise. The upper segment is slidably and rotatably connected to the lower segment allowing the lower segment to be twisted and moved rectilinearly relative to the upper segment. The lower segment is terminated at the bottom in an elastomeric pole tip for absorbing shock. The lower segment pole tip may also incorporate a spring.

Abstract: A boom brake for controlling the swinging motion of the boom of a sailboat includes a housing attached to the boom having two plates between which three bearing surfaces are mounted to engage a line attached to the sides of the sailboat in a serpentine path such that the line makes less than a full turn around each bearing surface to preclude overwrapping of the line. At least one of the bearing surfaces can be adjustably rotatable such that the force required to cause rotation can be selectively controlled. Braking of the boom motion is provided by sliding friction between the line and the bearing surfaces.

Abstract: System for controlling a boat sail as it is dropped, the sail being made of flexible material and being folded to lie when it is a mainsail, for example, on top of the boom of the boat. One or more control lines run parallel to the mast from the boom to a topping lift. The control lines run through grommets in the sail, the grommets being disposed in horizontal alignment with respective sliding fastening means by which the sail is attached to the mast. Equidistant between each pair of successive horizontal rows of grommets and the respective sail fastening means aligned therewith there is a batten which extends from the leading edge to the trailing edge of the sail. The control lines run through successive vertically aligned grommets so as to lie alternately on one side and then the other side of the sail.
