does the superconducter YBCO which will be used in the applictions' electricity, is considered a Going Green.

Question

i read the usually YBCO has a high tempereature but YBCO's low temoerature's create great magnatic fields that can reach up to 50 telsa, because tempreture is realated to kinetic energy, ergo, it may conturbute, in the Going Grenn movement, so can it, or not??? and how it is related to resistive magnets, thanks.....

Answer 1

From the wikipedia article on YBCO:
[Wiki article quote] YBCO has yet to be used in many applications involving superconductors for two primary reasons:

First, while single crystals of YBCO have a very high critical current density, polycrystals have a very low critical current density i.e., only a small current can be passed while maintaining superconductivity. ...

A second problem limiting using this material in technological applications is associated with processing of the material. Oxide materials such as this are brittle, and forming them into wires by any conventional process does not produce a useful superconductor. [End Wiki article quote]

Even if it had a high current density and was not brittle, the energy required to maintain a liquid nitrogen system to keep it superconducting would probably negate any gains you would get from increased efficiency in transformers and electrical power transmission.

So, YBCO probably won't contribute to "going green".
