Dutch Government for example has only 1 national supercomputer with 1024 processors. The other supercomputers the NWO has are way way smaller. We must not compare those with normal cpu chips but with the old Cray machines which started at if i remember bob's statement well around 500KWATT for just 4 processors. These chips take away a lot of research which otherwise actually must get done physically, which eats more resources. Completely in contradiction to the majority of pc chips which get used for simple business work which in theory a small pc from 10 years ago can do too, or games which even more power :) There were very good chips from MIPS which eated only like 0.5 watt for 200Mhz. Of course competition pushes things to higher standards and higher usage of power. A nasty side effect of all that power usage is that my dual K7 1.6ghz is producing a lot of sound. >FYI Transmeta sells Crusoe, a 5W VLIW x86 CPU.
