what if you used compressed air?  A tank of compressed air as a core would 
probably continue to arrive at similar hysteresis and inductance problems due 
to the tank, but the compressed air may provide some added benefit making it 
worth exploring?  You conceivably could build a coil inside a large tank and 
compress the air inside, but it seems teh tank woudl have to be pretty
large to 
test anything useful with it, and even then......

Heavy hypothesis... but can anyone speculate as to what effect compressed air 
would have upon a TC if used as the 'core'\
