Electric cane, superconducting electricity storage system "SMES"

It seems that it reads as "Smess". I thought that the technology was over to the doctor for a while, but it seems that it is being put into practical use properly.

In short, converting electric energy into magnetic energy makes it possible to "store" without causing loss. (Super electric motor is zero electric resistance)
Furthermore, since it can instantaneously output large power as a characteristic, it seems to be useful for instantaneous voltage drop, so-called "instantaneous electricity".

If you make a small version of this, it might be useful as an instantaneous electricity prevention function of UPS (uninterruptible power supply) ...?

Even if it says storage, it seems to be stored in "superconducting coil for electricity storage" ... What kind of thing is it?
The real thing looks like this


Small-scale power storage superconducting coil


Will it be small like this?

Is it so huge ......

It is said that the demonstration experiment of this will start with Chubu Electric Power.

Interconnection of superconducting electricity storage system to electric power system, Chubu Electric Power will begin demonstration test from next May
