Abstract: A power generation system including: a generator including a rotor including a superconductive rotor coil coupled to a rotatable shaft; a first prime mover drivingly coupled to the rotatable shaft; and a thermal radiation shield, partially surrounding the rotor coil, including at least a first sheet and a second sheet spaced apart from the first sheet by centripetal force produced by the rotatable shaft. A thermal radiation shield for a generator including a rotor including a super-conductive rotor coil including: a first sheet having at least one surface formed from a low emissivity material; and at least one additional sheet having at least one surface formed from a low emissivity material spaced apart from the first sheet by centripetal force produced by the rotatable shaft, wherein each successive sheet is an incrementally greater circumferential arc length and wherein the centripetal force shapes the sheets into a substantially catenary shape.

Abstract: A removable cover for a container and a container having the removable cover. The cover may be adapted with an opening to enable wire to pass through the cover with the cover disposed on the container. The container may be adapted to be lifted by inserting a fork, or other lifting member, of a lifting device into the container. The container may comprise a fiber drum having one or more openings, or recesses, adapted to receive a fork of a lifting device. The container may be cylindrical. The container may be adapted to store wire. An adapter assembly may be disposed on the cover to protect the opening in the cover and to direct movement of the wire.
