Abstract

L'invention concerne une utilisation d'un ensemble supraconducteur et un système de transport comprenant un ensemble supraconducteur. Selon l'invention, le champ magnétique effectivement parasite d'un ensemble supraconducteur traversé par un courant est utilisé pour l'alimentation d'un consommateur servant en même temps de système de lévitation électromagnétique pour un moyen de transport. L'ensemble conducteur forme par conséquent "accessoirement" un rail de support et/ou de guidage pour une capsule de transport pouvant être déplacée et maintenue en lévitation au moyen du champ magnétique le long de l'ensemble supraconducteur sans contact sur la longueur de celui-ci. La grande complexité des infrastructures nécessaires pour un refroidissement s'étendant sur la longueur d'une ligne électrique supraconductrice, refroidissement dont le fonctionnement nécessite en outre des coûts élevés et de grands besoins d'énergie, n'est ainsi prise en considération qu'une seule fois. Les lignes électriques dont on a grand besoin deviennent ainsi en même temps un système de transport moderne et inversement.
