A Brooklyn spa and a Finnish district heating system are demonstrating how cryptocurrency mining can be put to good use heating water, rather than going to waste.
The process of bitcoin mining requires huge amounts of energy, typically producing copious amounts of heat from its computers that is wasted.
The Brooklyn-based Bathhouse spa decided to use the heat from its cryptocurrency mining activities to heat its pools.
In a similar move, Finnish company Marathon Digital Holdings is using fleets of its bitcoin miners to heat the homes of 80,000 residents.
Although concerns have been raised about the vast amount of energy required to create cryptocurrency, using some of this energy to heat buildings and water is being seen as a more sustainable option.
