There is a difference between air conditioning, heat pump, and 
evaporative cooling. I think evaporative or heat pump is a great way to 
go and I don't get why most datacenters still seem to do standard air 
conditioning. But there is definitely still cooling and associated costs 
involved, even in the new IBM setup. And what IBM is doing isn't new or 
unique.

Check out pages 10-13:

A heat exchanger built into the back door of the rack. Available from
Panduit right now. Connect it to a heat pump or just run the water
outside to a cooling tower for evap cooling. Neat. I found out about it
from this thread on the NANOG mailing list:
