An electrical question

    I was wondering me if an electrical generator produces a larger amount of electrical energy if I rotate the stator on the contrary direction that of the rotor one.

    Well, I was thinking in a double eolic generator, with two rotors spinning opposite. One rotor attached to the electrical rotor, and the other one attached to the electrical stator.

    What do you think, cowboys?

    Well the only way to increase power output for the same power input would be to increase efficiency. Adding a second set of brushes and larger gaps (because of the two counter-rotating concentric assemblies and their tolerances) would be seem to be counter productive to that goal. Plus the additional brushes, contacts and bearings add to complexity and cost.
