Passive 2-phase immersion cooling is often misunderstood. There is no need for a chiller, it uses a simple dry tower, which is essentially the same thing as a radiator in the front of your car or your water cooling system of a PC. And it also works in very hot climates.

The systems are designed to work with hot water (aka hot water cooling). It takes very little energy to cool water from say 70C to 50C even when it's extremely hot outside like in Arizona or other hot places. (this hot water can in fact also be used to heat up buildings like schools or offices)

The PUE of less than 1.01 includes the _total_ cooling process, including device and building cooling. There is nothing else required. There is no trickery. In fact it's less than that. If you'd use wet towers, or a river near by, it would be lower. But why waste the water and waste time with an open system (needs frequent cleanup)?

Thank you for the explanation. We'll continue the discussion in HK 2014

I found the discussion quite informative.

What are your thoughts on IM DCs now, after having learned more about the process at HK?

All I'm saying is mount the Bitcoin mining chips (on small PCBs) directly onto your secondary cooling loop.

Why doesn't anyone (manufacturer + purpose-built mining facility) do this?

I've really enjoyed meeting and discussing IC with Alex.
Alex is a terrific guy, passionate about his business. I wish him and AC best of luck. Really. I think that the eco system will become stronger if AC will succeed.
I still believe that it's too expensive solution for Bitcoin space. I'm under NDAs and can't elaborate.
