(57) ABSTRACT

Techniques for generating poWer are provided. Such tech niquesinvolveathermodynamicsystemincludingahousing, a turbine positioned in a turbine cavity of the housing, a compressorpositionedinacompressorcavityofthehousing, and an alternator positioned in a rotor cavity betWeen the turbine and compressor cavities. The compressor has a high pressure face facing an inlet of the compressor cavity and a loW-pressure face on an opposite side thereof. The altemator has a rotor shaft operatively connected to the turbine and compressor, and is supported in the housing by bearings. RidgesextendingfromtheloW-pressurefaceofthecompres sormay beprovidedforbalancingthrustacrossthecompres sor. Seals may be positioned about the alternator for selec tively leaking ?uid into the rotor cavity to reduce the temperaturetherein.
