Abstract: A tide activated power system has a plurality of horizontally oriented cylinders that each have a pair of chambers. The cylinders are carried on float/weight barges that are located in a lagoon. A plurality of float/weight barges each have at least two cylinders in series. Each cylinder has a chamber holding a piston movable in the chamber defining a pair of variable size chambers: a flood variable size chamber and an ebb variable size chamber. As the float/weight barge rises and falls on the tide in the lagoon, the variable size chambers vary in size and force a working fluid to a turbine generator to create electrical energy. The piston of each of the multiple cylinders of the multiple barges forces combined to move the working fluid above the turbine generator where the flow drives the turbine generator prior to returning to the cylinder. In alternative embodiments, other mechanisms convert the energy from the rising and falling of the flow/weight barges to a non-uniform motion in one direction.

Abstract: For protecting surface floating wave energy converters (WEC's) against surface turbulence, the WEC's are removed from the water surface. For reducing the force required, the WEC's include a hollow member having an apertured outer wall. In the case where the WEC is to be lifted out of the water, the hollow member is normally submerged and full of water, and, during its lifting, water drains through the wall apertures thereby reducing the weight of the member and reducing the force required to lift it. In the case where the WEC is to be submerged, the hollow member is normally empty of water but fills with water through the wall apertures as the member is pulled beneath the surface. The weight of the water reduces the force required to submerge the member.

Abstract: An apparatus comprising the use of at least two or more vertically disposed tubular structures with each tube filled with water, and having a nozzle-like conduit at one end. Inside each tube is a sealed cylinder or float for containing either gas or water. When gas is introduced into the float positioned at the bottom of the tube, the float begins to ascend inside the tube causing the water advancing ahead of the rising float to become increasingly more pressurized due to the buoyancy effect. Maximum or near maximum pressure levels are reached when the water advancing ahead of the rising float reaches the top of the tube and is forced through the narrow conduit and the interconnected flow line. At the top, the gas in the float is replaced with water compelling the float to sink to or near the bottom of the tube where the water is replaced with gas, and the process is repeated.

Abstract: A method is invented for converting heat in a liquid to power and generating thermal difference of the heat source liquid between the inlet and the outlet of a machine. The heat source liquid (8) is drawn to the lower right side of the cylinder (1) through the inlet (5). The heat in the heat source liquid (8) boils the working liquid (2) at the right side of the cylinder (1). The vapor from the boiling creates pressure to push working liquid (2) to the left of the cylinder (1) and to compress the vapor at the left side back to working liquid. The buoyant force on the right and the gravitational force on the left of the cylinder (1) rotate the cylinder (1) to produce power. As heat is transferring to the cylinder (1), the temperature of the heat source liquid (8) is lower at the outlet (4).

Cog wheels are connected to the cell. The cog wheels are connected to the shafts of generators. Rotation of the cog wheels operates the generators which produce energy. The cog wheels engage anchor chains or vertical supports. One end of each anchor chain is secured to an anchor located at the bottom of the body of water. The other end of the anchor chain is secured to a float which floats at or near the surface of the body of water. The up and down movement of the cell causes the cog wheels to move upwardly and downwardly along the anchor chains and thereby rotate. This rotation drives the energy generator and generates energy, preferably electricity. The cog wheels are permitted to rotate upon the receipt of a request for energy. This results in a highly efficient source of energy or electricity.

Abstract: An apparatus and process for capturing power or mechanical work from the kinetic energy of a moving vessel driven by buoyancy and gravitational forces. The apparatus is capable of bifurcating the buoyancy force into a first component used to compress the gas necessary to sustain the vertical oscillation cycle of a moving vessel, and a second component that drives a means for converting energy. The apparatus generally comprises a moving vessel, a gas compression means, a force transfer means, a conduit, and a force recovery means. In use, the submerged moving vessel receives compressed gas so that the moving vessel's buoyancy force becomes greater than its downward gravitational force, and the moving vessel begins to rise through the water. As the moving vessel reaches the top of its upstroke, the moving vessel releases the gas, thus causing the moving vessel to sink.
