also, keep in mind these numbers:
the current total generation capacity (which in reality is only about 80% of this) of the USA is 1.3 terawatts. so, 1300 gigawatts.
if you divide the number of gigawatts (which as i pointed out you need one to run the 1 million qbit computer) by each person in the USA, you come out to 35kw per capita capacity, and individuals are using about half of that at peak draw on a 16A circuit, probably also about teh average size of a small household circuit. so one of these computers uses the same power as about 280,000 people worst case at everyone using the full 35kw of power. so the machine is also bidding up the cost of electricity to the size of a medium sized city, just for one. this would probably mean the effect on power prices would be to nearly double them, and people would be screaming about it.
