Field of InventionThe Bartons Float Generator is a device which is generated toward the art of generating alternative energy using water currents, water waves or water elevation changes.Description of related artCurrently the state of this art is there are very few devices devoted to the art of alternative energy that are efficient, effective and practical.The purpose of the Bartons Float Generator is to provide alternative energy that is effective, efficient and practical. Unlike other devices that generate electrical power from water currents, water waves or water elevation changes, The Barton Float Generator uses multiple linear motions to generate electrical energy. Other devices that use these methods, only generate an electrical charge when a particular motion is generated. For example, these devices rely on an elevation rise or a wave to positively change the elevation of the device to generate an electrical charge; if there is a negative elevation change in the water the device does nothing. This makes them ineffective and not versatile, where the Barton Float Generator can generate an electrical charge in a positive or negative change. The Barton Float Generator does not use motors, gears or dangerous chemicals making the Barton Float Generator cleaner safer and more cost effective while maintaining efficiency and practicality. The Barton Float Generator consists of a float which will move up or down in ...

Disclosed is an apparatus that floats at the surface of a body of water over which waves pass. Passing waves cause a nominally vertical axis of the apparatus to tilt away from an axis normal to the resting surface of the body of water. Tilting of sufficient magnitude and duration allows a fluid to flow through a channel that in an un-tilted apparatus would require the gravitational potential energy of the fluid to increase (i.e., to flow uphill), but, because of the tilt allows the fluid to flow through the channel in a downhill direction. Flowing water is trapped at a plurality of levels which in an un-tilted apparatus are higher than the respective levels from which the fluid has flowed. A subsequent tilt of the apparatus in a sufficiently different direction, and of a sufficient magnitude and duration, causes the trapped water to flow to new, yet higher levels. Successive wave-driven tilts of the apparatus incrementally raise water to a height and/or head from which a portion of its gravitational potential energy can be released, and/or converted to electrical power, by causing the water to return to a lower level by flowing through a water turbine thereby energizing an operationally connected generator, or through some other apparatus that performs a useful function when supplied with a flow of high-pressure water. 1. An electrical generator powered by oceanic surface waves , comprising: a top surface;', 'a bottom surface;', 'a peripheral wall connecting the top and bottom surfaces;', 'a first, circuitous fluid path extending from a lowermost tier to an uppermost tier;', 'a vertical channel defining a second, direct fluid path and extending from the uppermost tier to the lowermost tier, the vertical channel having a reducing cross sectional area in a direction of fluid flow;', 'a mass of fluid trapped inside the peripheral wall between the top and bottom surface;, 'a sealable, multi-tier tank comprisinga turbine disposed within the vertical channel; anda ...

OCEAN WAVE ENERGY ABSORBING KITE SYSTEM AND METHOD

An ocean wave energy absorbing kite system captures an ocean wave's kinetic energy as a force on a submerged, reciprocating panel that drives the panel back and forth in an oscillating motion. The force applied to the panel is transmitted to a power generator through opposed flexible ropes or lines loaded in tension. Potential energy is captured from the wave as a vertical force when a buoyant volume attached to the energy absorbing panel or kite member rises on a passing ocean wave's peak, and transmits the force through flexible ropes or lines in tension to a power generator. Optionally, the shape of the panel is configurable to limit or restrict absorbed wave energy, thereby preventing damage from larger storm-generated waves. 121-. (canceled)22.

An assembly for converting linear and rotational motions of a floating vessel into electrical energy. The assembly provides a floating vessel, such as a boat, and an operationally connected power generation unit that harnesses the natural buoyant movements of the vessel to generate electrical energy in the power generation unit for use by the vessel or other electrical consumption system. As the vessel moves in linear and rotational movements, the power generation unit reciprocally pivots. This pivoting motion urges a push rod in and out of the power generation unit. A piston extends from the push rod. A reservoir feeds hydraulic fluids through a closed loop system. The piston urges the hydraulic fluid into a hydraulic motor that creates a mechanical action. A generator converts the mechanical action to electrical energy. A platform pivots between a table position and a step position to provide greater functionality of the vessel. 1.
