1. A steam engine comprising:
(a) an engine case comprising a first section and a second section;
(b) a stator between and affixed to the first section and the second section of the engine case, the stator having a radially-inner surface defining a plurality of recesses;
(c) a steam generator comprising a hollow generator body having a water injection port for entry of water into the generator body and an open outlet end for the release of steam from the generator body, the outlet end being affixed to the first section of the engine case, the steam generator having heating means for generating steam from water in the generator body;
(d) a rotor rotatably supported by the engine case, the rotor comprising:
(i) a rotor shaft having a hollow section therein comprising a steam distribution chamber, the steam distribution chamber being arranged to receive steam from the outlet end of the steam generator;
(ii) a plurality of steam distribution channels extending radially outward from the steam distribution chamber, each channel having an inlet to receive steam from the steam distribution chamber and an outlet for the flow of steam into the stator recesses, the channels being oriented to direct steam into the stator recesses at an angle from the normal;
(iii) a plurality of pressure relief ports at a radially outer perimeter of the rotor arranged for the flow of steam from the stator recesses into the engine case; and
(e) one or more condensation circuit ports in the engine case for the flow of steam from the engine case to a steam condensation circuit.
