So you're actually doing this, or just describing it? Antminers? How many kW?
Solo mining was the important part.
I haven't started recycling the waste heat yet... thinking of trapping heat with an intercooler in a bath of Novec but need more time to test the efficiency of several designs.
Disclosing capacity details or ones exact location isn't advisable for miners in general as there are many security considerations to be aware of, so lets stick to the more abstract reasons why I mentioned how one can compete with large industrial miners and still remain profitable.
There are many other incentives we can discuss which increase profitability of solo/p2pool miners as well I can discuss...
