    Gravitational descent of fluid —produces→ Mechanical motionestablishedclaim record
    mechanical → mechanical · loss to thermal
    • falling or flowing water transfers weight and momentum to waterwheel buckets or paddles
    • producing shaft rotation
    liquid · bulk flow required
    refs [1]
  3. 03
    Mechanical motion —drives→ Rotating-machine generator actionestablishedclaim record
    mechanical → electrical · loss to thermal
    • a shaft turning a rotor inside a stator, or a magnet moved past a coil
    conductor required · magnetic field required
