Would it not currently be cheaper to run these in a home since that would be on a domestic (capped) electricity tariff if they paid back the householder for the energy consumed compared to business tariffs which are currently much, much higher?
Not saying this concept is a good idea, just an interesting thought exercise.
As to dust which someone mentioned you'd only get dust with active cooling via fans, I thought the whole point of this was that it was a sealed black box so all the heat could be transferred to the tank?
