Power transmission ideas

Hi all.

Had a few ideas this morning which might be useful.
It occurs to me that transmission losses in cables (typically braided high tensile steel) account for 12% or more,
additional losses are in HV-LV conversion in large, heavy heat producing transformers.

My idea is to use the superconducting proximity effect to boost efficiency in the system, using a magnesium diboride inner core to the braid but energizing it at radio frequencies tuned to the Cooper pair resonance band.
This if done correctly would cause the surrounding cheaper metal (ie pure Al) to superconduct and be able to pass massive amounts of current without quenching despite the MgB2 being at only 220K.
Something like cold nitrogen (not liquid) would work as coolant and be environmentally friendly.

EDIT: May have to use strontium copper oxide as an intermediate layer for this to work.
Also could alloy other elements ie selenium with the aluminum to boost its performance, this is routinely done in other materials and lowers resistance substantially due to the formation of nano-filaments within the bulk.
Al is routinely alloyed with Bi to improve machinability so the right alloy could support proximity HTSC if cooled down enough.

Could this possibly work?

Kind regards, -A
