A system for electrical energy generation from steam, the system comprising at least one stage, each stage comprising:
- at least one steam-driven rotating toroidal ring, the toroidal ring comprising a major-radius and a minor-radius, the rotating toroidal ring for rotation within a plane coinciding with the major-radius of the rotating toroidal ring and comprising a least one steam channel for translating force components of steam pressure into rotational motion, the steam comprising enthalpy, the rotating toroidal ring further comprising at least one magnetic field source arranged to create a time-varying magnetic field occurring in at least one specific region adjacent to the rotating toroidal ring as the rotating toroidal ring rotates;
- at least one housing comprising a toroidal cavity for containing the rotating toroidal ring, the toroidal cavity comprising a major-radius and a minor-radius, the major-radius of the toroidal cavity accordingly slightly larger than the major-radius of the rotating toroidal ring and the minor-radius of the toroidal cavity slightly larger than the minor-radius of the rotating toroidal ring so that the rotating toroidal ring is free from contact with the housing and can freely rotate within the housing, the housing further comprising at least one steam inlet, the at least one steam inlet for providing incoming steam to a plurality of steam nozzles pointing into the toroidal cavity for directing pressurized steam into the channels for at least a first portion of rotation of the rotating toroidal ring, the housing further comprising a plurality of steam outlets for removing pressurized steam from the channels for at least a second portion of rotation of the rotating toroidal ring within the toroidal cavity;
- at least one bearing arrangement comprised by or attached to the housing within the toroidal cavity, the bearing arrangement for supporting the rotating toroidal ring within the toroidal cavity of the housing, and
- at least one pair of electrical coils, each electrical coil located on the outer surface of the housing at locations diagonally opposite from the other coil of each pair across the axis of the minor radius of the toroidal cavity and within the specific region where a time-varying magnetic field will occur as the rotating toroidal ring rotates, each pair of electrical coils oriented so that variations in the magnetic field produced by rotational motion of the magnetic field source comprised by the rotating toroidal ring can create an electrical current in the pair of electric coils,
- wherein the rotating toroidal ring lies within the toroidal cavity of the housing in a manner where it can freely rotate when driven by steam pressure as supported by the at least one bearing arrangement;
- wherein the rotating toroidal ring serves as a rotor and the housing serves as the stator housing of an electrical generator, and
- wherein steam entering the toroidal cavity through the steam nozzles and exiting through the steam outlets forces the rotating toroidal ring rotor to rotate within the stator housing, thus creating a time-varying magnetic field that creates an alternating current generated within the at least one pair of electrical coils, thus forming a steam-powered electrical alternating current generator.
