| A liquid metal fueled Brayton cycle power system with a direct contact heat exchanger. In this invention, a compressor compresses the working gas. A regenerator preheats the compressed working gas and passes the working gas to a reactor/storage tank with liquid metal fuel stored therein. An oxidant is injected into the reactor/storage tank to react with the liquid metal fuel. The compressed working gas bubbles through the liquid metal fuel in the reactor/storage tank and is heated by direct contact with the fuel-oxidant mixture. A turbine expands the heated working gas and thereby withdraws power from the system. The spent working gas exits to the regenerator where it warms the compressed gas. A cooler reduces the working gas temperature and recirculates the gas to the compressor. | ||||||

| An engine/heat pump is shown. Most of its parts rotate around the same central axis. It comprises two doubly connected chambers. Blades in each chamber substantially rotate with the chamber and may be firmly attached to the walls of the chamber, thus forming a modified centrifugal pump with axial input and discharge. An expandable fluid is rotated outward by one of the pumps and then heat is added for an engine or removed for a heat pump as the fluid is being sent to the outer part of the second pump. The fluid travels toward the center of the second pump, thus impelling the pump in the rotation direction. Then heat is removed for an engine or added for a heat pump as the fluid leaves the second pump and travels back to the first pump near the center of rotation of both pumps. Rotation energy of the fluid is typically much larger than the circulation energy. A modified centrifugal pump with axial discharge having a casing rotating with the blades is also claimed. | ||||||

| This invention relates to the production of engines based on a new physical principle in which the engines will extremely quickly change the physical state of fluids or solids, especially the substances with low boiling points such as liquid water, liquid nitrogen, CO2 powder, in which the outputted mechanical energy is significantly greater than the inputted energy to operate the engine. The engine is called engine for dispersing matter into the surrounding space in order to produce mechanical energy, or in short, matter-dispersing engine.At the same time, this invention also relates to the production of engines based on the concept of extremely quickly changing of matter (or high-speed dispersion of matter into the surrounding space) with the result that the elements being changed their physical states in the engine will move at a great positive acceleration and apply to members of the engine and generate great amount of mechanical energy. The engine operates when the fuel and an oxidant (with or without other substances like fluid water, fluid nitrogen, etc.) are placed in the two chambers separated by a partition wall which then suddenly is removed to allow the communication between the two chambers, this will result in the reaction between the two highly-condensed components; the fuel and the oxidant reacting with each other will quickly be expanded in an environment with a lower pressure to generate mechanical power; if these elements are ejected out of the chambers, the engine will generate mechanical power as thrust and is called a jet engine with partition; and if this process of expansion is used to generate mechanical power to rotate the members of the engine, the engine is called an explosion motor with partition. The jet engines with partition wall can produce powerful propulsion forces and explosion motors with partition can produce great amounts of rotary mechanical energy using little fuel. | ||||||

| A device for storing and releasing hydrogen gas. The hydrogen gas can be used to drive pneumatic mechanical mechanisms. The hydrogen gas is stored in a metal hydride material. The metal hydride is in thermal contact with a thermoelectric module (10) (TEM). When acted upon by an electrical current through the TEM one volume of metal hydride (12) is heated and releases hydrogen gas while a second volume of metal hydride (28) is cooled and absorbs hydrogen gas. There is a pressure difference generated between the heated volume and the cooled volume. This difference in pressure is used to drive a pneumatic-mechanical mechanism to perform work. | ||||||
