A rotary directional pressure engine having a case within which a plurality of rotors rotate in parallel. The rotors include asymmetrical cavities on the circumferential faces thereof, which cavities function to move air and/or other gases into a combustion chamber area during an intake phase, to cooperatively form a combustion chamber during an ignition and combustion phase, and to move exhaust gases to the area of one or more exhaust ports for removal from the engine during an exhaust phase. Continued rotation of the rotors is accomplished by harnessing and properly directing the forces of combustion against the asymmetrical cavities of the rotors.

Embodiments of the present invention relate to a steam turbine in which unnecessary axial force is reduced. The steam turbine is capable of preventing a working fluid discharged from each nozzle-equipped rotary body from acting as resistance to the nozzle-equipped rotary bodies. The steam turbine includes a housing, a turbine shaft supported pivotably in the housing, a nozzle-equipped rotary body, and a guide panel. The nozzle-equipped rotary body is in the shape of a plurality of disks stacked along the axial direction of the turbine shaft, is integrally coupled to the turbine shaft, and has at least one or more nozzle holes formed therein so as to rotate as the working fluid is ejected. The guide panel is positioned at the rear end in a flow direction of the working fluid of the nozzle-equipped rotary body and fixed to the housing to guide the flow of the working fluid.

A tapering exponential spiral for a gas expander for work extraction or air cooling. A gas compressor to increase the pressure and temperature of air. The compressor-expander forms a single and simple structure.

A generator with a disk format using a circle of alternating polarity magnets to induce current in polygon solenoids.

A heat turbine, Firefly Electric, is small, simple, and efficient heat engine.

A heat pump, Firefly Air, for cooling, refrigeration, water capture, and heating. Solar power can be generated and stored as compress air.

A water purifier, Firefly Aqua, to desalinate water by solar power. Sunlight is concentrated by a sun tracking conic reflective surface onto a column of salty water. Solar photovoltaic power can be used to power a spiral compressor to condense low pressure steam. Also, we reuse solar heat by extracting the heat of compressing and condensing steam for evaporating more salty water under reduced pressure.

The present invention relates to an axial flow turbine, comprising: a rotor mounting part; a housing having a fluid supply part surrounding the rotor mounting part; a rotor which is installed at a rotation shaft installed in the housing and has a plurality of blades installed in a circumferential direction; and a plurality of injection nozzles, installed in the fluid supply part surrounding the rotor mounting part, for spraying a high-pressure fluid toward the blades, wherein the fluid collision surface of the blades installed at the rotor is formed to be inclined at an angle in the rotational direction of the rotor with respect to the normal axis of the rotation center axis, and the injection nozzles formed in the fluid supply part are installed at an angle parallel to the normal direction of the fluid collision surface of the blades. Due to the aforementioned configuration, the present invention provides the effect of maximizing the rotation rate of a turbine while smoothing fluid flow by optimizing the angle of the fluid collision surface of the blades.

A turbine with rotary blades includes a stator, a rotor rotational about an axis of the turbine and rotational blades evenly spaced around a circumference of the rotor. The turbine includes a pressure chamber circumscribed by a slot and a sealing chamber between which an inlet channel for a medium supply leads into the pressure chamber. The slot, the sealing chamber and the blades are adapted to permanently seal both the slot and the sealing chamber with at least one blade. The rotation of the blades can be ensured by a toothed gear, wherein angular speed of the blades is an integer multiple of the angular speed of the rotor. The blades may have a front wall and a rear wall of approximately conical or cylindrical shape.

A radial expander having a rotor mounted in a housing and comprising multiple blades. The blades together with a radially inner hub contour of a rotor hub and a radially outer housing contour define flow channels for the process gas, which process gas to be expanded enters in a radial direction and from which expanded process gas exits in the axial direction. The radially inner hub contour of the rotor includes a curvature change at least in some circumferential positions seen in the meridional section such that adjacent to a flow leading side of the rotor, the radially inner hub contour, seen in the meridional section, is curved radially to the outside and adjacent to a flow trailing side of the rotor, the radially inner hub contour, seen in the meridional section, is curved radially to the inside.
