Do you have _any_ clue what kind of power a super-computer sucks down?  IE
crays start at 500KVA power supplies...    That is volts * amps, with the
usual power supply taking in 480 volts.   so 480 volts at a total of 1000
amps.  That is 500 killowatts of power, vs 50 for the typical PC.  The
machine IBM is going to build would probably need 1000X that much power.

So a million times more power would barely get it powered up...
