Another example of a rational approach to bitcoin mining is shown by the Norwegian Bitcoin mining company Kryptovault, which uses the heat from bitcoin mining to dry wood and provides this opportunity to local loggers for free. The amount of heat produced by mining plants is enough to achieve complete drying of wood in just a few days, despite the fact that the drying process takes place outside, often under snow and rain.

The company is also conducting preliminary negotiations on the drying of seaweed for a local company, by the way, Kryptovault had to spend about £1.5 million on noise insulation only to reduce the noise created by asics after complaints from neighbors.
