I've shared this before and I think heatbit is going to do it, but the heat could be used to create air conditioning (or at least cooling) in the way a propane fridge works.
Also, a miner could also be made to work as a dehumidifier.

A dehumidifier is a great idea.
I''m starting to think this is the way of the future as the mining rewards get smaller.
