Abstract:
An improved design for maintaining nanometer separation between electrodes in tunneling, thermo-tunneling, diode, thermionic, thermoelectric, thermo-photovoltaic, current limiting, reset-able fusing, relay, circuit breaker and other devices is disclosed. At least one electrode is of a curved shape whose curvature is altered by temperature. Some embodiments use the nanometer separation to limit or stop current flow. Other embodiments reduce the thermal conduction between the two electrodes when compared to the prior art. The end result is an electronic device that maintains two closely spaced parallel electrodes in stable equilibrium with a nanometer gap there-between over a large area in a simple configuration for simplified manufacturability and use to convert heat to electricity or electricity to cooling, or limit current flow, or interrupt current flow.
Abstract:
A device and method for directly converting thermal energy to electricity are disclosed. The device comprises a first surface and second surface preferably of different materials, and a gas medium having gas molecules in thermal motion between the surfaces. The first surface is operative to transfer charge to gas molecules interacting with the first surface, and the second surface is operative to receive the charge from gas molecules interacting with the second surface.
Abstract:
An improved design for maintaining separation between electrodes 1, 2 in tunneling, diode, thermionic, thermophotovoltaic and other devices is disclosed. At least one electrode 1 is made from flexible material. A magnetic field B is present to combine with the current flowing in the flexible electrode 1 and generate a force F that counterbalances the electrostatic force or other attracting forces between the electrodes. The balancing of forces allows the separation and parallelism between the electrodes to be maintained at a very small spacing without requiring the use of multiple control systems, actuators, or other manipulating means, or spacers. The shape of one or both electrodes is designed to maintain a constant separation over the entire overlapping area of the electrodes 1,2. The end result is an electronic device that maintains two closely spaced parallel electrodes 1,2 in stable equilibrium with a uniform gap therebetween over a large area in a simple configuration for simplified manufacturability and use to convert heat to electricity or electricity to cooling.
Abstract:
A current source and method of producing the current source are provided. The current source includes a metal source, a buffer layer, a filter and a collector. An electrical connection is provided to the metal layer and semiconductor layer and a magnetic field applier may be also provided. The source metal has localized states at a bottom of the conduction band and probability amplification. The interaction of the various layers produces a spontaneous current. The movement of charge across the current source produces a voltage, which rises until a balancing reverse current appears. If a load is connected to the current source, current flows through the load and power is dissipated. The energy for this comes from the thermal energy in the current source, and the device gets cooler.
Abstract:
A thermionic electric converter includes a cathode output enhancing laser (374) operable to direct a laser beam (376) to strike an emissive surface of a cathode emitter (321), to increase the electron output of the cathode emitter (321). The cathode output enhancing lase (374) is positioned to direct a laser beam (375) through an opening (370) in the anode (306) or target structure, in the direction of the cathode emitter (321). An electron repulsion ring (380) is provided at an edge of the opening (370) in the anode (306), to reduce the number of electrons missing the anode (306) and passing through the opening (370) in the anode (306).
