http://www.spraycool.com; immersion is not necessary. This is how the
new Cray X1 is cooled. In theory it could hit the mainstream in ~ 5
years. It is the only technology I have seen capable of dealing with
the power density of a small server built using Itaniums. So it
doesn't attack the real issue (high watts/GFlop), but it papers
over it nicely.

google says someone claims the real quote is:

"If you were plowing a field, which would you rather use? Two strong
oxen or 1024 chickens?" -- Seymour Cray

Of course, both the X1 and the Earth Simulator are an army of oxen,
not just a brace.
