Generating energy from fluid expansion

Номер: US20120013125A1
Автор: David J. Huber, Lawrence A. Hawkins, Scott R. Myers
Принадлежит: Calnetix Inc

An apparatus includes an electric generator having a stator and a rotor. A turbine is coupled to an end of the rotor to rotate at the same speed as the rotor. The turbine may rotate in response to expansion of a working fluid flowing from an inlet side to an outlet side of the turbine. The apparatus also includes a housing assembly with an inwardly oriented shroud, which is located at close proximity to the turbine. The proximity of the shroud to the turbine establishes the pressure ratio of the turbine, allowing the system to operate without seals. Magnetic bearings and position sensors are used to maintain the distance between the shroud and the wheel. In certain implementations, the positioning of the turbine can be controlled to optimize machine performance.

Electricity is the vital energy that we are dependant upon. To produce electricity there are several methods. This electrical generator converts weight energy into electrical energy through a system that has a static magnet with the coil of wire that can rotate within the magnetic field. This coil is attached to the shaft with the wheel. This wheel is made to rotate by the toothed shaft which is connected to the top plate. The top plate when pressed due to mechanical weight makes the wheel rotate which in turn rotates the coil within the magnetic field, thus electricity is generated. The miniature form of this kind of electricity generators can be constructed with in the sole of the shoes, medium sized generators can be constructed at homes, and large sized generators can be constructed under the roads. With this electricity generator, every man and every vehicle can produce electricity with out expenditure & with out fuel.

A roadway arrangement comprises a first road segment; an upper bridge mounted for rotational movement about a pivot axis relative to the first road segment; a lower bridge, including one or more upwardly extending segments; and a second road segment. As a vehicle travels from the first road segment and starts moving across the upper bridge, the upper bridge will rotate downward about the pivot axis and will continue to rotate until the one or more upwardly extending segments of the lower bridge extend through respective openings defined by the upper bridge, at which time the vehicle will transition from driving on the road surface as defined by the upper bridge to driving on the road surface as defined by the upwardly extending segments of the lower bridge. The movement of the upper bridge produces work, which can then be used for power generation.

When the current running toward the drive part ( 30 ) exceeds the rated value of the drive part ( 30 ), the power supply circuit ( 16 ) automatically stops power supply to the drive part ( 30 ). On the other hand, when the output voltage of a battery ( 50 ) drops and the battery ( 50 ) is put in an overdischarge state, power supply to the drive part ( 30 ) is automatically stopped. When it is detected that the battery ( 50 ) undergoes an abnormal event, power supply to the drive part ( 30 ) is automatically stopped.

In a conventional compressor, since a motor and a mechanical section of the compressor are disposed in one and the same closed container, the motor is exposed to high-temperature coolant and heated, and the efficiency of the motor is lowered. Further, during the operation of the compressor, the coolant circulating in the refrigerating cycle conveys additional heat generated by the motor coil. Thus the efficiency of the refrigerating cycle is lowered. The compressor according to the present invention includes a compression chamber divided into a closed chamber and an open chamber separated by a magnetic induction plate from each other. The closed chamber is filled with high temperature and pressure coolant and the rotor of the motor is disposed in the closed chamber, and the stator of the motor is disposed in the open chamber.
