It would be interesting if a bitcoin miner could replace a large building's furnace with their equipment, using the "waste" energy to provide heat to offices/apartments.

As bitcoin mining boxes can be spun up at a moments notice, they could be used to take advantage of the "free" electricity that is generated when Denmark's wind turbines are producing more electricity than there is demand.
(the denomination of newly-created bitcoin is adjusted to keep the growth rate at the prescribed amount regardless of how much CPU power is dedicated to mining. So regardless of the bitcoin price, the energy needed to mine new bitcoin is close to the value of bitcoin created. Otherwise mining would be a free lunch.)
