  • Heat generator
    Patent number: 10425998
    Abstract: A heat generator comprises a fluid input and fluid output, an electrically conducting disc mounted on a shaft, a plurality of magnets with their N-S axis aligned parallel to the plane of the first disc are mounted either side of the disc, a plurality of runner vanes upstanding from the disc and forming a plurality of widening fluid paths towards the magnets and allow fluid to flow over a vane free portion of the disc to exit the heat generator though the output. Drive systems are described in which high pressure fluid from a hydraulic motor connected to a turbine or Archimedean screw is used to drive the disc.
