Abstract
This paper presents a superconducting thermo-magnetic-mechanical (STMM) energy conversion process. This energy conversion concept revolves around of utilizing a cryogenic coolant, e.g., liquid nitrogen, as a thermal energy facilitator to cool down the superconductor to below the critical temperature. Then, utilizing the mixed state, i.e., Meissner effect and weak vertex - which leads to partially shielding the magnetic field - an external magnetic field is used to apply force on the superconductor and create motion. The concept proposed is demonstrated using thorough Multiphysics understanding i.e., thermal, magnetic, and mechanical. The proof of concept is completed by using a combination of analytical and numerical simulations and calculations, and measurements. Using this concept, a practical automotive drive has been theoretically designed and compared with a counterpart electric drive. The proposed technology has a potential to provide a step change for the sustainable cleaner cost-effective transportation.
