This might have some application as a timer (stuff happens when the SHLD disappears) or a kind of 'tamper-proofing' system (stuff happens if the TTAN is interfered with)
Interesting. With the TTAN coating, the pressure inside the wire shoots up due to the repeated SPRKs generating pressure each time they pass - it destroys the SHLD when the pressure on the outer surface reaches 7.00, and continues climbing. But the QRTZ never breaks from this pressure (I watched it until it reached 150, then got bored!). If the TTAN is then removed when the pressure is already high, THEN the wire shatters.
It has problems with pressure, since QRTZ becomes extremely brittle at low temperatures and PQRT does not conduct electricity. I would suggest replacing the SHLD with INSL adjacent to the QRTZ, then TTAN outside that.

Thanks for the idea!
