Cooling is part of the Power Usage Effectiveness (PUE).
Thank You.
Sorry buy you need to review all the plan.

Sorry but you need to understand PUE
http://en.wikipedia.org/wiki/Power_usage_effectivenessHes right on track, except I would charge a lot less to host than a data center
I founded and sold 2 ISPs in my life one with a quite big hosting and colocation data center.
If he plan to use Cointerra devices is 1200 W +/- 20% each, the to cool down in a "regular" data center 2440 W per unit with the electricity cost Supercomputing is saying, what is not possible in most States and in just few countries he will need much more money, Is not the same to host 2 or 3 machines that create excessive heat and power usage in a Data Center, that is lost in all the facility, you have 95% customers using less than expected energy and cooling and one 5% over the limit at the end you dont care, If the same guy wish 50 racks all changes, and you review all after seeing your premium customers complaints about the Room temperature and after receiving the electricity bill, as a Data Center owner you call the guy and say "hey joe this is not working for us".
Bitcoin mining require a different Data Center, one where cooling is very cheap and probably uses the outside cool air in some way and outside air needs to be cool, and a lot of electricity, Electricity in bitcoin mining is like the Bandwidth in a regular data center.
We can discuss it if you wish but really Supercomputer has a nice idea but he is not considering many things in the costs area and not only in Data Center, he is doing the number like if a miner is a standalone server that you leave it there and works alone, and the equipment is almost experimental you require to manage the volume of machines he wishes 2 guys 24/7 on site, with knowledge of bitcoin mining, so you need 8 bitcoin mining admins, plus lets say one chief, how he is going to pay that?
The plan is a nice idea but needs a lot of improvement, total cost per machine will be over u$s 250 near $400 most probable.
