Claim:
A superconducting rotating machine comprising: a. at least one right-handed superconducting helixes, and b. said right-handed superconducting helixes being pivotably disposed, and c. said right-handed superconducting helixes having an axis of rotation along the lengthwise center of radius of said right-handed superconducting helixes, and d. at least one left-handed superconducting helixes, and e. said left-handed superconducting helixes having an axis of rotation along the lengthwise center of radius of said left-handed superconducting helixes, and f. said right-handed superconducting helixes and said left-handed superconducting helixes being constructed using a high temperature superconductor material, and g. means for holding said axis of rotation of said right-handed superconducting helixes and said axis of rotation of said left-handed superconducting helixes substantially parallel and in a fixed position, and h. said right-handed superconducting helixes and said left-handed superconducting helixes being disposed in an external magnetic field, and i. rotational drive means applied to said right-handed superconducting helixes and said left-handed superconducting helixes for producing opposite direction rotation of said right-handed superconducting helixes and said left-handed superconducting helixes, and j. cryogenic cooling means applied to said right-handed superconducting helixes and said left-handed superconducting helixes for cooling said right-handed superconducting helixes below the critical temperature of said high temperature superconductor, Tc, and k. the rotation of said right-handed superconducting helixes and said left-handed superconducting helixes across an external magnetic field induces eddy currents and opposing magnetic fields within the superconductors, and l. said induced eddy currents and opposing magnetic fields within the superconductors displaces said external magnetic field into a stronger part at the leading edge of said superconducting helixes and a weaker part at the trailing edge of said superconducting helixes, and m. said stronger part of the magnetic field and said weaker part of the magnetic field produce, by the principle of the Meissner effect, a force on said superconducting helix that is at right angles to the helix angle and at all locations that said eddy currents are induced, and n. said forces at all locations that said eddy currents are induced when combined produce a torque that opposes the rotation of said helixes and a linear thrust.
