How long before this shows up in our stereo equipment?
Cool electric motors too.

The HTS wires AMSC manufactures today conduct over 150 times the electrical current of copper wire of the same dimensions, which dramatically reduces the size and weight of electrical equipment and significantly increases the power throughput of power cables. These characteristics offer product developers the ability to design components with HTS wire -- such as coils for industrial motors or generators -- that deliver much higher power density and can offer additional benefits such as reduced manufacturing and maintenance costs.

The cryogenic cooling system power consumption is less than a few percent of the total losses in the machine.
