[Fourlanders] engineering challenge

[Tom McElroy]

This is a fun thing to think about.  A big flywheel comes to mind.

Some guy took out a patent on using suit-case-sized capacitor banks to
supply the peak impulse power to the tube:

But gee whiz, when you bottle up *that* much energy in a cap,or a flywheel
watch out!

If the X-ray machine control circuits aren't too sensitive to voltage sag,
maybe you could get away with heavier AC mains wire, and big slo-blow!
