I have run earth mover tractor type inner tubs, car and truck tire inner
tubes, etc, in the early 1990s.

They work great when covered with aluminum foil.

  I had a problem though.  With the onset of winter the air in
the tube contracted in my un-heated lab.   The foil then shriveled up on
the reduced size toroid and permenant wrinkles appeared.  Refilling a bit
actually stressed the Aluminum and it tore in a few places.  Finally, I
don't know what caused this, but I came out one day and the giant 65"
diameter inner tube was wilted down over the Nemesis coil like a big
silver condom!  I thought this might have been the rubber succumbing to
the UV/ozone exposure and deterioration along chemical lines took its
toll, or just a chance punture.  I haven't used inner tubes since that
time.

What about filling the inner tube with something other than air, like that 
spray insulation which quickley hardens??
