Speaking of exotic wire, has anyone heard of using "hollow" wire? The same
day that my Navy-trained electronics instructor told the class about Litz
wire, he also mentioned using the concept of using hollow wire. It would
have more surface area, and be less affected by skin effects, but I've
never heard anyone else mention this type of wire. I'm not sure if he was
referring to metal tubing, or to perhaps to a metal sheath layered over a
non-conductive solid core. (The latter design would prevent flattening, if
the wire was bent.)
