JR Tokai Senior Corporate Executive Officer Noriyuki Shirakuni speaks in Minato Ward, Tokyo, about the company’s maglev system development.


Quote:


Even though this system generates an electrical current that continues to flow almost indefinitely, the hurdle has been putting it into practical use because a slight increase in heat means superconductivity cannot be maintained.

“The most difficult thing was to properly maintain the state of superconductivity,” said JR Tokai Senior Corporate Executive Officer Noriyuki Shirakuni, [...].

“A big thing was establishing technology to maintain the state of liquid helium and to reduce the amount of heat emitted by stabilizing the magnet,” he said. In the current maglev system, the superconductive state is achieved by cooling to minus 269 C a Niobium-titanium alloy with liquid helium.
[...]

“We want to improve our technology to control the amount of shaking and noise of the maglev train, putting it on par with the Shinkansen bullet train,” he said.
