why i dont understand the need for it to go so high. it is one or only metal as a conductivity metal. if it gets high new technology might need to be discovered (or already is>) if it gets too high. always wondered about that aspect. i know they are out of sinc as to me gold was said to be made by outer earthers. so with that there is no limitations except for its usage only as jewelry etc? just asking cause i dont understand the whole thing..
