    I couldn't resist jumping in when I read a remark that the term
    "high power" used with regard to coin shrinkage was "incorrect." The
    same remark went on to say that high current to push high voltage was
    not high power. 

    This is not the case. Voltage is the push to current (Ohm's Law).
    Power includes a time element (power is simply energy released per
    unit time), so very high voltage systems need only push small current
    in a short time to yield high power. Now imagine a system that can
    release very high current (pushed by high voltage) in a tiny fraction
    of a second; the result is extremely high power, even if only for a
    nanosecond. That pretty much is what happens in the coin shrinker.
