The model offers economic and environmental benefits with respect to moving people, cargo, and energy.
The concept flips the idea of magnetically levitating trains that operate on a magnetized rail, withEmbedding superconductors into the existing highway infrastructure and adding magnets to the undercarriages of vehicles lets such systems avoid having to cool the superconductors on each vehicle. The model relies on liquid hydrogen to cool the superconductors as it moves across the system, with "liquified nitrogen and a vacuum layer used to thermally insulate the liquified hydrogen.
"Superconductivity has had such promise to transmit electric power without power loss, to power magnetically levitating, super-fast trains and for energy storage. But it has not been economically viable, which is why it hasn’t happened at a large scale yet," said Zhifeng Ren, director of the Texas Center for Superconductivity at UH, who devised the concept and is a corresponding author on the paper.
Such a system can also dramatically reduce the consumption of fuel or electricity. At the same time, the car or truck is placed on the superconductor guideway, "reducing both the cost and the environmental footprint." The team has yet to completely resolve the technical and financial aspects of implementing such a system. According to the team, combining transit and energy systems and using existing roadways would substantially lower the cost of any individual system. Researchers hope its long-term economic and
