1. A slip ring assembly for use in a selected application for transferring electrical power between a stationary exterior environment and a rotating interior environment, comprising:
a. a non-rotating electrical power member, comprising:
i. a first electrically non-conductive spindle having a generally planar contacting surface;
ii. a first set of concentric channels formed in said first electrically non-conductive spindle planar contacting surface;
iii. a first set of concentric electrically conducting power transmission cylinders, with each having inside and outside surfaces, wherein each power transmission cylinder within said set fits within a separate channel of said first set of concentric channels and extends out past said generally planar surface;
iv. a set of first electrical wires with each member within said first wire set connected to one said electrically conducting power transmission cylinder and extending from said non-rotating electrical power member;
b. a rotating electrical power member, comprising:
i. a second electrically non-conductive spindle having a generally planar contacting surface;
ii. a second set of concentric channels formed in said second electrically non-conductive spindle planar contacting surface;
iii. a second set of concentric electrically conducting power transmission cylinders, with each having inside and outside surfaces, wherein each power transmission cylinder within said set fits within a separate channel of said second set of concentric channels and extends out past said generally planar surface, wherein when rotationally mated with said first set of concentric electrically conducting power transmission cylinders paired power transmission cylinders result with the inside surface of one cylinder sliding over the outside surface of another cylinder;
iv. a set of second electrical wires with each member within said second wire set connected to one said electrically conducting power transmission cylinder and exiting from said rotating electrical power member; and
c. a housing that surrounds both said non-rotating electrical power member and said rotating electrical power member to align said first set of concentric electrically conducting power transmission cylinders and said second set of concentric electrically conducting power transmission cylinders to slide over one another on their said inside and outside surfaces during rotationally operation of the slip ring assembly.
