摘要:
A portable power system has a turbine engine generating mechanical energy. A homopolar electrical machine receives this energy. The homopolar electrical machine has a single stationary superconducting field coil configured to create a magnetic field. A homopolar rotor is configured to rotate within the magnetic field such that a rotating magnetic field is created in a stationary winding by interaction of the rotating permeance wave produced by the homopolar rotor and the magnetic field produced by the single stationary field coil. The homopolar electrical machine is configured as a generator and produces electrical power for the portable power system.

A high power density generator contains an armature structure having a plurality of conductors and at least one heat transfer tube thermally coupled to the conductors. The tube is hollow so as to allow a heat transfer fluid to pass through it. The tube is made of a material having a thermal conductivity λ of at least 20 W/mK, an electrical breakdown strength of at least 60 V/mil, and a mechanical strength adequate for handling, manufacturing and operation. In an embodiment of the invention, the tube is made of a ceramic material.

The present invention solves the aforementioned problems by providing a vacuum seal assembly for a high power generator stub shaft which includes a seal stator encircling the stub shaft and a plurality of oil seals disposed on an inner diameter of the seal stator and encircling the stub shaft. Adjacent oil seals form a plurality of seal cavities between the stub shaft and the seal stator, and define gaps between each oil seal and the stub shaft for receiving a lubricant film. At least one seal feed conduit extending through the seal stator into the plurality of seal cavities to provide lubricant to the seal assembly.

A method for collective socializing using a mobile social network, which includes obtaining collective socializing data on at least one location, and transmitting the collective socializing data upon request of at least one user. In addition, the step of obtaining collective socializing data on at least one locations further includes storing the collective socializing data on the at least one location on a system server, obtaining additional collective socializing data from a plurality of users on the at least one location; and combining the additional collective socializing data with the collective socializing data on the system server for transmittal to the at least one user upon request.

A cooling system is provided for supplying cryogenic cooling fluid to a thermal load. The system includes a cryogenic refrigeration system, a cryogenic cooling fluid coupled to the thermal load, and a primary power supply for providing power to the cryogenic refrigeration system. A backup power supply provides power to the cryogenic refrigeration system in the event that the primary power supply is unable to provide sufficient power to the cryogenic refrigeration system.
