Since watts is an instantaneous measure, i.e. power, and not a measure of
total energy, it is not impossible or even unlikely to be able to draw
25,000 watts from a storage capacitance ultimately driven by a 9 volt
battery.  Consider that 75,000 volts applied to 220,000 ohms will cause
330 milliamps -- thus 25,000 watts.  It might only be able to do this
for a picosecond, but none the less, the initial instantaneous power
would in fact be 25,000 watts!  Also note that 220,000 ohms is a good
approximation  of the resistance of the human body (varies widely, but
220k is a good worst case.)
