摘要： A fluid propulsion system configured to propel an ambient fluid through a propulsion channel. To do so, the present invention includes a hollow main body having a propulsion channel extending therethrough. The main body includes a base structure, a flexible bladder attached thereto, and a fluid (e.g., liquid, gas, or plasma) enclosed within the bladder. The present invention further includes a field source that produces an electromagnetic or magnetic field. The bladder and/or the enclosed fluid is configured to respond to the electromagnetic or magnetic field. Movement of the bladder in response to energization of the field sources alters the amount of occlusion of the propulsion channel. Energizing sequential field sources causes the occluded section of the bladder to propel the ambient fluid through the propulsion channel creating a reactionary force to propel the fluid propulsion system in the opposite direction.

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.

摘要： Two-phase LMMHD energy conversion systems have potentially significant advantages over conventional systems such as higher thermal efficiency and substantial simplicity with lower capital and maintenance costs. Maintenance of low velocity slip is of importance for achieving high generator efficiency. A bubbly flow pattern ensures very low velocity slip. The full governing equations have been written out, and a computer prediction code has been developed to analyze performance of a two-phase flow LMMHD generator and nozzle under conditions of no slip. Three different shapes of an LMMHD generator have been investigated. Electrical power outputs are in the 20 kW range. Generator efficiency exceeds 71 percent at an average void fraction of about 70 percent. This is an appreciable performance for a short generator without insulating vanes for minimizing electrical losses in the end regions.

摘要： A electrical generator that uses wasted heat that emanates from an external heat source to generate electricity. The generation of electricity is based on known thermo-electric principles, electro-chemical principles, magneto-hydro-dynamic principles, the Hall Effect, and electro-static principles. The electrical generator uses a plurality of plates of different thermo-electric conductive materials to generate electricity. Those plurality of plates are stacked on top of the other in a certain order. Each plate has the same array of through holes. Those through holes form an array of lineal channels through the stacked plurality of plates.
