  • Publication number: 20070251241
    Abstract: A hydrogen-fired all-in-one electric generator/turbine that requires less rotational energy, substantially fewer parts, and less space in the power plant than traditional designs. The turbine is embedded within the rotor, each sharing a common, shaftless axis of rotation, and as a result, reduces the overall weight and size of the turbine/generator. The electric generator is energized by an energy capture system that captures the heat and thrust produced from a hydrogen and oxygen reaction. This is accomplished by means of heat exchangers and turbines, as well as the aforementioned generator/turbine. The system is intended to replace steam generators that rely on fossil fuels and uranium and used in electric power plants. These power plants will be able to install more generators in the same amount of space. More generators operating at higher rates of rotation will significantly increase the electric power generated.

  • Publication number: 20070216245
    Abstract: Lacking a physical axis of rotation, this all-in-one electric generator/turbine requires less kinetic energy, substantially fewer parts, and less space in the power plant than traditional designs. The turbine is embedded within the rotor, each sharing a common axis of rotation. This design eliminates the connecting shaft between the turbine and generator, and as a result, reduces the overall weight and size of the turbine/generator. Power plants will be able to install more generators in the same amount of space. The reduced weight of the turbine/generator permits the generator's rotors to operate at a greater number of revolutions per minute. More generators operating at higher rates of rotation will significantly increase the electric power generated. Also disclosed is a means of converting low head dams and reservoirs into hydroelectric electric power plants.

  • Publication number: 20070096569
    Abstract: A versatile, efficient, compact pump featuring an all-in-one rotor/blade design. Utilizing the concepts of a three-phase AC synchronous motor, this invention is capable of the heavy lifting required along California's aqueducts as well as for propelling large vessels. Reduced weight, size and complexity results in energy savings when compared to conventional designs.

  • Publication number: 20060237972
    Abstract: Lacking a physical axis of rotation, this all-in-one electric generator/turbine requires less kinetic energy, substantially fewer parts, and less space in the power plant than do traditional designs. This is achieved by attaching the generator's magnets directly to the outer surface of the Hollow Turbine's rotating cylinder. Rotating magnetic fields generate current in adjacent stationary coils of an electric conductor. The design eliminates the need for a separate rotor and related shaft, as found in standard electric generator designs.

  • Publication number: 20060192387
    Abstract: A buoyancy means and apparatus for providing near friction free operation of rotational devices, particularly electric generators and or turbines. This feature is critical in ocean energy projects where the amount of kinetic energy to be harvested is less than optimal. Flotation devices are affixed to rotational devices and submerged into a heavy fluid encased within a chamber that does not interfere with the normal operation of the said rotational device. Vibration is also reduced, allowing for more precise operation and a longer life cycle for moving parts.

  • Publication number: 20050178113
    Abstract: An uninterruptible rotational energy supply calibrated to provide constant rotational energy to electric generators and other apparatus in environments where fluctuations in kinetic energy are found. Such environments include the pause between the ebb and flow of the oceans' tides and waves as well as variations in the velocity of the oceans' currents. Wind-driven turbines may also be another beneficiary of this technology.

  • Publication number: 20050034446
    Abstract: An energy capture system to capture the heat and thrust produced from a hydrogen and oxygen reaction. This is accomplished by means of heat exchangers and turbines. It is intended to replace steam generators that rely on fossil fuels and uranium and used in electric power plants. This invention also provides for the capture of the water produced, from the said reaction, and may be used to supplement or completely supply a community's water requirements.

  • Publication number: 20050005592
    Abstract: A versatile turbine suitable for both hydraulic and pneumatic applications. The turbine's blades are affixed to the inner surface of a cylindrical shell which is free to rotate about an outside supporting structure. Rotational energy is transferred from the outer surface of the rotating cylindrical shell, usually by means of a gear; however, there may be applications better suited for a pulley means of transfer. The vacant central axis of rotation can be closed, by incorporating taller blades to achieve a larger surface area, resulting in greater efficiency, or open, by means of shorter blades forming a hole with the distal edges of the blades, to allow for passing fish and or debris to safely exit. The preferred embodiment further includes a means for electricity generation, water purification, and hydrogen production.

  • Patent number: 4801479
    Abstract: A decorative article is made by a process in which a controlled-flatness substrate having an effective edge in a closed pattern on its surface receives a fluent plastic composition which is cast into an area defined by the edge. The fluent plastic flows to the effective edge and is then cured to form a clear plastic cap. During casting and curing the substrate is held flat and horizontal by reason of its being releasably adhered to a flat, smooth-surfaced, stiff release liner. The resulting decorative article is free of optical distortions and may be used as a covering preferrably for elongated automotive components such as the external vertical pillars between the passenger compartments of automobiles.

  • Patent number: 4034708
    Abstract: A machine for holding a release sheet on which emblem substrates are mounted while plastic is cast on the substrates and for holding the release sheet and substrates and curing the plastic includes a radiation source which is movable into a position above the release sheet. The platen holding the release sheet has a first cavity which is partially evacuated and which communicates with the upper surface of the platen through a plurality of openings. A second cavity in the platen receives temperature stabilizing fluid. Control circuitry is provided permitting alteration of the operation sequence of the machine.
