Cutting plasma rope

Hot wire/blade seems to be *the* method.

Perhaps a blade heated by the engine exhaust since an electrical system
might be subject to 'system bugs'. Actually its not such a stupid idea cone
to think of it. The blade/cutter mechanism needs to be on the glider side of
the winch and therefore downwind of the winch driver.

The only other solution I can think of is a blade that completes a circuit
across a primary battery when it is in the cutting position but that would
take a few seconds to heat up to the plasma melting point.

Has anyone contacted Marlow ropes in E. Sussex to find out what they
recommend? They manufacture Dynema cores sailing lines I think.

There is considerable interest in the UK in using
plasma/dyneema rope for winch launching. However,
the main obstacle appears to be finding an efficient
method of cutting the rope in event of an emergency.
Has anyone ot there found the definitive method???
