Hi David,

Thats very very impressive 540J in the volume of 2 MO caps WOW. That's
comparable to an electrolytic cap for energy density.
It would require more than 1500 Panasonic 0.15uF/2kV to do that.
But as its has been said before its one thing for a cap to have to charge
for a few seconds a few times a day.
and its a completely different duty to operate continuously.

Seriously off topic (sorry Terry) but what the h$## are they trying to do to
the patient 540J into his chest!!
Does it double as an elephant defibrillator too !!
