whats the deal here????
i dont see how anyone could possibly use HT superconductors in a tc spark
gap.... YBCO is superconductivce at only a little above the temp of liquid
nitrogen... more exotic thallium based superconductors work at about 150k,
but still, you still have an atmospheric spark gap.. you still have hot
plasma.. this is going to generate enourmous heat... causing your
superconductor to go normal, and turning it into a rather poor conductor at
that... the loss in a spark gap is not due to the resistivity of the
electrode materials, but that of the spark it's self...

sounds like a bunch of hot air to me
no pun intended
