A multifunctional highway system incorporating superconductor levitated vehicles and liquefied hydrogen
O Vakaliuk et al 2023 APL Energy 1, 016107 (open access)
…We envision combining the transport of people and goods and energy transmission and storage in a single system. Such a system, built on existing highway infrastructure, incorporates a superconductor guideway, allowing for simultaneous levitation of vehicles with magnetized undercarriages for rapid transport without schedule limitations and lossless transmission and storage of electricity…
Strictly application-oriented REBCO bulk fabrication
U Floegel – Delor et al 2020 J. Phys.: Conf. Ser. 1559 012046 (open access)
…we demonstrate strictly application-oriented fabrication close to the final geometry and thus reducing mechanical machining and assembling work. YBCO hollow cylinder design for journal bearings with radial c axes orientation are obtained by radial-seeding geometry (RSMG). YBCO ring tiles up 120 mm show a perfect cylinder…
HTS Bulk Experiments Performed for and Under Space Conditions
F Werfel et al 2019 IEEE TAS, 29 5 6802105
In the shadow of dominant long-length hightemperature superconductors bulk HTS show a considerable effort of magnetic engineering application. Bulk HTS are capable of providing easily magnetic fields of several tesla, levitates selfstabilized mirrors or measuring instruments, and can be used as a passive magnetic shield…
Mobile HTS Bulk Devices as Enabling Ton-Force Technology for Maglev Trains
U Floegel-Delor et al 2019, IEEE TAS 29 5 3601705
The status of bulk superconductor magnetic levitation (Maglev) train technique is evaluated. Existing industrial magnetic trains (electromagnetic, electrodynamic) point to key performance factors as load, speed, efficiency and environmental protection. On that basis a feasibility analysis of trapped-field train demonstrators…
Superconductor bearings, flywheels and transportation
F Werfel et al 2011 Supercond. Sci. Technol. 25 014007 (featured article)
This paper describes the present status of high temperature superconductors (HTS) and of bulk superconducting magnet devices, their use in bearings, in flywheel energy storage systems (FESS) and linear transport magnetic levitation (Maglev) systems. We report and review the concepts of multi-seeded REBCO bulk superconductor…
