Abstract:
An electricity generator comprising:an electrically conductive and annular inner collector having an inner wall and coaxially arranged along an axis of rotation to intersect a magnetic field perpendicularly for rotating about the axis of rotation in a first direction; a magnetic field source for providing the magnetic field extending radially with respect to the axis of rotation and for rotating about the axis of rotation in the first direction with the inner collectors wherein the magnetic field source is enclosed by the inner wall; an electrically conductive outer collector coaxially arranged along the axis of rotation to intersect the magnetic field perpendicularly for rotating about the axis of rotation in a second direction opposite the first direction; a first output terminal and a second output terminal for coupling an electrical current to an electrical load; a first electrical connection between the first output terminal and the inner collector; a second electrical connection between the inner collector and the outer collector for conducting the electrical current across the inner collector through the magnetic field opposite and parallel to the electrical current flowing across the outer collector through the magnetic field; and a third electrical connection between the outer collector and the second output terminal; wherein the first, second, and third electrical connections are stationary with respect to the axis of rotation.
