paraphrasing Shakespeare ...

Methinks thou art 3 orders of magnitude too high and protesteth too much.

2.2MW anyone?  2200kW = 2.2MW.  Per node.  Thermals on that are gonna be 
wild ...

At SC15, we saw the Russian machines at 400kW/rack ... so ... I am 
assuming a typo here ...

FWIW: they were using specialized nodes and liquid cooling in closed 
loops.  I think it was DI water, but I don't quite remember.

Incredible (performance) density, tiny space.
