1. A generator comprising
at least one rotor,
at least one magnetic bridging element arranged to rotate about a rotation axis of the rotor in response to the rotation of the rotor,
at least one inductance unit comprising an inductance coil and a magnetic element at an area of an influence of the moving magnetic bridging element for inducing electromotive force in response to the movement of the magnetic bridging element relative to the inductance unit, and
at least one flow channel unit for conveying a fluid flow to the rotor for operating the rotor,
wherein the rotor is arranged to rotate relative to the flow channel unit,
wherein the flow channel unit comprises at least one channel for conveying at least one fluid flow between the flow channel unit and the rotor to create a pressure effect between the flow channel unit and the rotor to push, in the axial direction of the flow channel unit and the rotor, the rotor away from the flow channel unit such that a gap is arranged between the flow channel unit and the rotor for allowing the rotor to rotate relative to the flow channel unit substantially friction-free, and
wherein the flow channel unit comprises at least one channel for conveying at least one fluid flow to the rotor for rotating the rotor.
