Claim Text:
1. A diamagnetic levitation system for levitating users to a diamagnetic levitation surface, said diamagnetic levitation system comprising: a) open horseshoe or U-shaped superconducting magnet segments connected in series to form a superconducting magnet segment assembly and a plurality of said superconducting magnet segment assemblies connected in series to form said diamagnetic levitation system which generates said diamagnetic levitation surface; b) each said superconducting magnet segment assembly having surface magnet segments which maintain said diamagnetic levitation surface and edge magnet segments which prevent objects and users from falling off sides of said diamagnetic levitation surface; c) each said superconducting magnet segment having one or more cryogenic cooling tubes to cool said superconducting magnet segment to a superconducting temperature with cryogenic liquid; d) each said superconducting magnet segment generating a magnetic field strength up to 30 tesla; and e) said cooling tubes having internal spiral fins to produce a uniform film coating of said cryogenic liquid on an interior surface of said cooling tubes, wherein gas bubbles generated from heat absorption by said cryogenic liquid travel down a center of said tube, and wherein said cooling fins have a pitch angle of 5 to 25 degrees.
