Specific operation is executable in a Rankine-cycle power-generating apparatus. In the Rankine-cycle power-generating apparatus, a) in the specific operation, the control device adjusts the degree of opening of the opening/closing device so that the direct-current electric power absorbed by the electric power absorber approaches first electric power, or b) in the specific operation, the degree of opening of the opening/closing device is increased to the predetermined intermediate degree of opening so that the direct-current electric power absorbed by the electric power absorber falls within a predetermined range.

A system for communicating in a transportation system is disclosed. A mobile device with a metro-application program in a communication link with a metro-station controller. The metro-station controller server communicates with the mobile device via the communication link, where the metro-station controller authenticates the mobile device based on the metro application program then the metro-station controller transmits the mobile device information to a metro-web server. The metro-station controller receives mobile device information where the metro-station controller compares the mobile device information with information stored on a database of the metro-web server, where if the mobile device information matches information stored in the database of the metro-web server then the mobile device is confirmed. The metro-web server transmits a message to the metro-station controller to allow the mobile device to access information on the metro-station controller to go through a turnstile.

Sequence, order and arrangement referred to as the package. ORC and SCO2 Brayton Cycle Fuel Cells size reduction from plant size CHP to less than 3.5 cubic feet of the package and installing package into existing EVselectric vehicles, transform former EVs into PPP EVsPortable Power Plant Electric Vehicles thus dispersed autonomous energy.

A buoyant rotation device has a casing, a rotating cylinder, and multiple floating elements. The casing has a body with an opening and two connecting boards. The rotating cylinder is rotatably mounted in the casing and has an inner tank, an outer tank, multiple dividing panels, and two side panels. A part of the rotating cylinder extends out of the body. The inner tank has a holding shaft. The outer tank is mounted around the inner tank to form an annular space, and has multiple main inlet holes formed through the outer tank and communicating with the annular space. The dividing panels are deposited in the annular space at spaced intervals between the inner tank and the outer tank to form multiple separate spaces not communicating with each other. Each one of the multiple floating elements is deposited in one of the multiple separate spaces of the rotating cylinder.

A cryogenic system to remove energy includes a heat engine to store content at a predetermined temperature; one or more fans to deliver air flow through the heat engine; a cryogenic storage unit to store cryogen and having one or more insulated pipes thermally coupled to the heat engine to cool the heat engine; one or more reuse pipes coupled to one or more insulated pipes to send a portion of cryogen gas flow back to the cryogenic storage for reuse; a controller to maintain the predetermined temperature; and an on-board power generator to supply operating power to the controller and the one or more fans.

The invention is a fluid handling process whereby a submerged pulsating low-pressure gas displacement pump is assisted by an inverted hydrostatic standpipe for the purpose of transporting ambient pressure liquid and gas. An apparatus with no moving parts pumps and transports gas and liquid at near-ambient pressure as a mixed medium by means of subtle design-induced pressure differentials within the inverted hydrostatic standpipe, siphon, pump chamber and riser, enabling conveyance over extended distances and inclined planes.

A permanent vertical hydraulic water cycle generator comprises a vertical principle axis, an electric generator installed on an upper end, a plurality of vanes installed on a lower end, at least four oil pressure jacks or four hydraulic oil cylinders uniformly installed around the upper end near the front end of the vanes, a piston provided on the top end of each oil pressure jack, water butted with the piston in a circular tube, and a high-tension switch installed on the top end of the circular tube. The permanent vertical hydraulic water cycle generator generates electricity permanently with a small amount of water and discharged water from air-conditioner as an energy supplement without any support cost, which is environmental friendly and highly profitable.

A water driven system for generating useful work has a floating support structure with a pair of spaced apart frame portions. A waterwheel is mounted between the two spaced apart frame portions in an upright manner. The waterwheel has a number of water receiving troughs for turning the waterwheel in response to a flow of water against the troughs when the floating support structure is mounted on a moving body of water. The waterwheel has side plates with outwardly extending axle shafts which are used to produce useful work as the wheel rotates.

The present disclosure discloses anti-drought and anti-flood by still water circulation generation. A pit (4) is dug near water (1), a water turbine (6) and a generator (7) are placed at the bottom of the pit, the water (1) on the pit (4) is released in a planned way along a water discharge pipe to drive a water turbine (6) to operate, a blade (11) and a chain (12) are meshed with an upper gear (9) and a lower gear (10), the upper gear (9) is driven by an electric motor (13) to drive the blade (11) to rotate such that the blade (11) inside a water outlet pipe moves upwards with water (1) circularly, thereby driving the generator to continuously generate power. The present invention is able to meet the power generation demand of users and is also capable of adjusting and meeting the local water consumption.

An generator/motor that initially uses external power to spin a partially submerged low drag fluid distributor rotor that uses centrifugal force to cause fluid to flow from the center of rotation, through a plurality of Euler curved penstocks, allowing the fluid to flow in a true radial direction through a high g artificial gravity field, which dramatically increases the fluid's kinetic energy and released available power (Pa), before it is guided out tangentially from the distributor via a plurality of nozzles symmetrically located at a small height just above the reservoir surface (near zero lift). As the frequency of the rotor is increased linearly the fuel artificial gravity increases exponentially, as does the fluid dynamic available power (Pa). Turbine runners on the rotor assembly capture the available power (Pa), and a positive feedback mechanical transmission couples the captured rotational power to the I/O shaft in its initialized direction thus replacing the external power with internal fluid dynamic derived mechanical power to sustain rotator rotation and drive the shaft of an electric generator.
