摘要： The present invention discloses a magnetohydrodynamics power system which utilizes low temperature heat source. Variable control of the operation of the system, along with determining configurations for specific cases, are made possible by selecting the refrigerant, liquid metal circuit geometry, and by adjusting the system condensing pressure and/or temperature. Adjustable condensing pressure and/or temperature allows the system to react to changing ambient temperature and maximize power output. Adjusting condensing pressure and/or temperature of the system is made possible with a variable condenser pressure controller. The variable condenser pressure controller allows utilization of the physical properties of the refrigerant over a wide range of condensing temperatures/pressures, including pressures in the vacuum range. Meanwhile rare earth permanent magnets in paired Halbach arrays are used in the magnetohydrodynamics generator to augment the magnetic field, and a series electrode connection is made possible to achieve a high voltage output.

摘要： A buoyant hydrodynamic pump is disclosed that can float on a surface of a body of water over which waves tend to pass. The pump incorporates an open-bottomed tube with a constriction. The tube partially encloses a substantial volume of water with which the tube's constriction interacts, creating and/or amplifying oscillations therein in response to wave action. Wave-driven oscillations result in periodic upward ejections of portions of the water inside the tube that can be collected in a reservoir that is at least partially positioned above the mean water level of the body of water, or pressurized by compressed air or gas, or both. Water within such a reservoir may return to the body of water via a turbine, thereby generating electrical power (making the device a wave engine), or else the device's pumping action can be used for other purposes such as water circulation, propulsion, or cloud seeding.

摘要： In one embodiment, a turbine includes a shaft and a turbine stage coupled to the shaft. The turbine stage includes a turbine blade. The turbine further includes a housing surrounding the turbine stage and a magnet located within the housing. The turbine is operable to receive an exhaust gas, generate a magnetic field using the magnet, and generate, by rotating the turbine blade, a current along the turbine blade in a radial direction toward the shaft. The turbine is further operable to ionize the exhaust gas between a tip of the turbine blade and the housing to form a plasma and electrically connect, using the plasma, the tip of the turbine blade to the housing.

摘要： The invention relates to the field of magnetohydrodynamic generators, and more precisely to such a generator (10) comprising a working fluid flow passage (11) that is defined by a first wall (12) and a second wall (13), an ionizing device (14) for ionizing the working fluid, a pair of arms (15), each connecting together the first and second walls (12, 13) downstream from said ionizing device (14) so as to define, within the flow passage (11), a channel (16) between said arms (15) and said walls (12, 13), said channel (16) being arranged to be traversed by a portion of the working fluid after it has been ionized, a magnet for generating a magnetic field (B) oriented in a direction that is perpendicular to the flow of the working fluid through the channel (16) defined by the pair of arms (15) and said walls (12, 13), and at least one pair of electrodes (17), each of the electrodes (17) in each pair being arranged on a respective side of the channel (16) defined by the pair of arms (15) and said walls (12, 13), said electrodes (17) in each pair being spaced apart from each in a direction that is perpendicular to said magnetic field (B) and to the flow direction of the working fluid through the channel (16) defined by the pair of arms (15) and by said walls (12, 13).

摘要： The improved liquid transportation and desalination system transports seawater or other saline liquids through a piped distribution system with essentially no moving parts by relying on MHD principles. A fluid pump device comprised of high-strength permanent magnets forming chambers through which the liquid passes and inter-chamber opposing electrode plates with an applied DC potential provide the magnetic flux density and electric current for generating the Lorentz forces acting on the liquid. The fluid pump device may be combined with a desalination filtration device for provision of fresh water near the end of the distribution line without the need for a largescale treatment plant. Desalination/filtration occurs through use of nano-porous graphene and/or carbon nanotube media.

摘要： The vertical pipe structure for water and energy harvesting is an artificial structure formed from concentric sets or rings of pipes having sufficient height such that atmospheric water vapor will condense on upper ends thereof. Water vapor condensing on external faces of the pipes flows downward, under the force of gravity, for collection in at least one reservoir. Water vapor condensing on internal faces of the pipes also flows downward within the concentric sets or rings of pipes for collection in an underground chamber. At least one hydrodynamic generator or the like is provided on the exterior of the artificial structure, such that water flowing thereover may be used for the generation of power.
