Relatively inexpensive as well ($70k?), compared to say national defense or welfare budgets.
Checking the math on the Register:
157 days, 23 hours, 31 minutes and 7.651 seconds = 3,791.51879 hours
$7.706976 x 3,791.51879 = 29221.1443181 or about 29,000
$0.57 x 3,791.51879 = 2161.1657103 or about 2,000
Adding the two priced numbers together gets 8.276976, which calculated separately times 3,791.51879 = 31,382.3100284. Adds up to ~60,000 if you include both numbers as two costs.
Where do they get the 70,000 figure? What am I missing? Data movement costs? Google hasn't disclosed the cost of the computation, which took the above length of time.
