Your site says $1/w but I'm assuming that's not right because that's about twice as expensive as 2 phase immersion cooling.
Where can I buy/rent 2 phase immersion cooling for 0.5$/W?
Not sure if you can rent them yet but you could probably buy a container from allied control.
Hopefully datatank gets going soon and sticks to their hosting plan at $60/kw.
I don't know how air cooled/single phase IC datacenters will compete especially considering the efficiency bonus you get from 2-phase. (65C chips vs 105C chips.)
