The difference is that the silver is 14g and the 12g copper is more than a half
inch wider.  Thanks for the heads up on this site.   I just wrote to them to
inquire if a 1000 or 1500 ft roll of this foil is available and what the price
would be.   They only show the foil conductor having a few types of backing ,
Kapton being the most suitable IMO, but I asked if polypropylene was available,
since it would be cheaper.  can you imagine a 1500 foot flat spiral secondary
of this foil?  I would make for one compact coil.   It would likely need to be
immersed in oil or something, but does give one food for thought.  If it comes
like a roll of tape,  no winding would even be necessary. 
Cheers, 
Mike
