What if I do this mechanism BACKWARDS?
 I.e., use a spring in extension mode.  Let the "carriage" STRETCH
it to a desired length (storing energy).  HOLD the "free" end of
the spring in place ELECTROMAGNETICALLY (!).
THIS is the solution!  One can purchase electromagnets that can
hold 40+ pounds (some operating at up to 100 pounds) for ~$75 (QTY1)
and operate them from a 24V supply with << 1A.
This has got to be the easiest way to avoid the mechanical mess
that comes with other "launch" schemes!
I will place an order after the holidays.  No idea what lead
times will be.
Maybe I can replace the spring with something else, at the same
time.  If the release/catch issue is out of the way the rest
should be easy!
