If rotor blades have such form that between them are formed channels which have between their inlets and outlets a narrow cross section, then when the rotor rotates a fluid flowing from the inlet into the narrow cross section accelerates reaching there an increased velocity which is so directed that the reaction of fluid's momentum drives the rotor then the rotor generates power consuming fluid's mechanical energy and when the fluid flows from the narrow to increasing cross section of the channel said momentum is absorbed by the downstream increasing fluid's pressure whereat the fluid converts its own heat directly into its mechanical energy which equals the sum of the energy which drives the rotor and the kinetic energy of the fluid issuing from the channels whereat the fluid issues from the channels correspondingly cooled.
