A turbine that has a plurality of compartments. Each compartment has associated thereto a respective opening. Each opening defining a fluid communication path between an outside of the turbine and a respective compartment. The turbine also has a plurality of conduits. Each conduit connects a respective compartment to an adjoining compartment. Each conduit defines a fluid communication passageway between the respective compartment and the adjoining compartment. The turbine is configured for immersion in liquid and for powering by gas displacing some of the liquid out of one or more than one compartment. The present disclosure also describes a method of driving such a turbine.

An energy harvester is provided. The energy harvester includes a permanent magnet and a coil. At least one of the permanent magnet and coil rotate completely about an axis such that relative movement between the permanent magnet and the coil is realized to generate an electrical current for use in powering a device.

An outlet device with collected the outer sound to control the waterway includes a shower, an electromagnetic valve, a control module and a power module with an impeller and a generator. The control module includes a sound detecting module, a calculating module, a processing module and a driving module. The sound detecting module collects the outer sound and outputs the control signal; the calculating module is connected to the power module to determine whether the real-time flowing value exceeds the preset value. If it exceeds the present value, the control module and the electromagnetic valve are turned off. The calculating module is connected to the sound detecting module and outputs the driving signal after receiving the control signal. The driving module is connected to the processing module and the electromagnetic valve. The driving module drives the electromagnetic valve when receiving the driving signal.

Various aspects of the technology provide for reducing noise and vibration in a pressure exchanger for high pressure fluid handling equipment such as a desalination system, by disposing grooves between a seal surface and a port. The groove reduces a hammer effect in moving high pressure fluid to a low pressure port and moving low pressure fluid to a high pressure port. Reduction in the hammer effect, in addition to reducing noise, reduces vibration that can cause deterioration of high pressure fluid handling equipment.

A hydroelectric power generator, comprising: a plastic seal outer shell;

a skeleton main body, disposed in the plastic seal shell; an embossed flat axis, disposed penetrating in the skeleton main body; an impeller, connected and fixed to one end of the embossed flat axis, to drive the embossed flat axis into rotation;
a magnet, sleeved around the embossed flat axis; a copper coil, disposed around the skeleton main body; a driving plate, connected and fixed to one end of the plastic seal shell, to drive the impeller into rotation; and a plurality of water input bosses, extending slantwise on the driving plate, having water input holes provided thereon. The hydroelectric power generator is simple in structure, easy to manufacture. In which, the slant water input holes on the driving plate are used in cooperation with the impeller, to raise the impact of the water flow.

A power generation apparatus using a head of wastewater in a building includes an inclined water discharge pipe connected to an end of a wastewater pipe installed in the building through one end thereof, to divert a moving path of wastewater falling through the wastewater pipe, a cavity part coupled to the other end of the inclined water discharge pipe, to receive the wastewater discharged through the other end of the inclined water discharge pipe, and a rotating body installed inside of the cavity part, to be rotated by the wastewater discharged through the other end of the inclined water discharge pipe. Power is generated using a head of wastewater generated in a high-rise building or an apartment, and electricity generated using the wastewater is used as common electricity inside/outside the building. Therefore, smooth power supply can be achieved.

A waste-watermill for generating electrical energy from a flow of waste water running through an underground waste-water conduit. The flow of waste water defines a free surface and a flow direction inside the waste water conduit. The waste-watermill comprises 1) a water wheel for being driven by the flow of waste water in an undershot configuration, 2) an axle for defining an rotational axis for the water wheel, where the flow of waste water passes below and transverse to the rotational axis in the undershot configuration, 3) a wheel support for rotationally supporting the water wheel in the undershot configuration and in a stationary position relative to the underground waste-water conduit, and 4) an electric generator operatively connected with the water wheel and the axle for being driven by the water wheel to produce electrical energy.

A combined pump and turbine (electromechanical converter), which may be operable as a motorized centrifugal pump for starting a siphon and as an electromechanical turbine particularly for transmission of a liquid, such as water, in a water treatment plant.
