Claim Text:
1. An apparatus, comprising: a rotor configured to rotate about a central axis, wherein said rotor has a first diameter, wherein said rotor comprises a first support ring oriented in a first plane that is perpendicular to said central axis and further comprises a second support ring oriented in a second plane that is perpendicular to said central axis, wherein said first plane and said second plane are parallel one to another, wherein said rotor further comprises a first plurality of rod shaped electrodes, wherein each rod thereof is parallel to all other rods thereof and to said central axis and has a first end and a second end, wherein each said first end is fixedly connected to said first support ring and each said second end is fixedly connected to said second support ring, wherein all of the rods of said first plurality of rod shaped electrodes are in electrical contact with each other rod of said first plurality of rods and wherein there is no direct electrical connection from any other element to said first plurality of rod shaped electrodes; a first stator and a second stator, wherein said first stator has a second diameter and is centered on said central axis, wherein said second stator has a third diameter and is centered on said central axis, wherein said second diameter and said third diameter are equal, wherein said first diameter is larger than both said second diameter and said third diameter, wherein said first stator comprises a second plurality of rod shaped electrodes, wherein all of the rods of said second plurality of rod shaped electrodes are physically parallel one to another, are in electrical contact one to another, are oriented to be parallel with said central axis and are evenly spaced around said central axis, wherein said second stator comprises a third plurality of rod shaped electrodes, wherein all of the rods of said third plurality of rod shaped electrodes are physically parallel one to another, are in electrical contact one to another, are oriented to be parallel with said central axis and are evenly spaced around said central axis, wherein said first stator is spaced from said second stator on said central axis, wherein the rods of said first plurality of rod shaped electrodes are physically parallel to the rods of said second plurality of rod shaped electrodes and said third plurality of rod shaped electrodes, wherein said rotor is rotatable only on the outside of said first stator and said second stator, both of which are within the inner diameter of said rotor, wherein there is no direct physical or electrical contact between said rotor and said first stator and between said rotor and said second stator; wherein said first plurality of rod shaped electrodes together with said second plurality of rod shaped electrodes form a first variable capacitor, wherein said first plurality of rod shaped electrodes together with said third plurality of rod shaped electrodes form a second variable capacitor; and a series-resonant circuit comprising a source of positive voltage electrically connected through a first inductor to said first variable capacitor which is connected to said second variable capacitor which is connected through a second inductor to a source of negative voltage, wherein said first plurality of rod shaped electrodes are at virtual ground and wherein said rotor is electrically isolated.
