Abstract
A generator (20) for in situ fluid-driven production of electric energy and also a method of making the generator (20), which comprises a stator and a rotor. The stator is formed as a turbine housing (1) having at least one internal cavity (2) within which at least one independent rotor body (3) is arranged without a fixed mechanical support in the turbine housing (1). The turbine housing (1) comprises at least one supply channel (8) and at least one discharge channel (9) connected to the cavity (2) for throughput of a generator-driving fluid (13). The cavity (2) is of a circular shape along at least one path of rotation therein, whereas the rotor body (3) is of a rotary-symmetrical shape for allowing rotation thereof along said path of rotation. The turbine housing (1) is provided with at least one coil (5) at the periphery of the cavity (2), whereas the rotor body (3) is provided with at least one permanent magnet (4) at the periphery of the rotor body (3).
