Claim Text:
1. A wind driven generator comprising: a first rotating element associated with a first set of vanes distributed so as to be driven by wind in a first rotational direction, the first rotating element having a horizontal axis of rotation, a second rotating element associated with a second set of vanes distributed so as to be driven the wind in a second rotational direction that is opposite to the first rotational direction, the second rotating element rotating concentrically with the axis of rotation of the first rotating element, the first rotating element having magnetic elements disposed thereon that project a magnetic field towards and onto the second rotating element, the second rotating element having electromagnetic coils disposed thereon, the electromagnetic coils being exposed to the magnetic field projected from the first rotating element, and at least one electrical lead connected to the second rotating element to carry current away from the second rotating element, the first set of vanes and the second set of vanes being adjacent each other without an intervening support pole for the generator, wherein the first rotating element and the second rotating elements operate independently of each other, wherein the magnetic elements and the electromagnetic coils are radially disposed with respect to each other with respect to the axis of rotation of the first rotating element.
