Tiny data centre used to heat public swimming pool

The heat generated by a washing-machine-sized data centre is being used to heat a Devon public swimming pool. The computers inside the white box are surrounded by oil to capture the heat - enough to heat the pool to about 30C 60% of the time, saving Exmouth Leisure Centre thousands of pounds. The data centre is provided to the council-run centre free of charge.

Start-up Deep Green charges clients to use its computing power for artificial intelligence and machine learning. Founder Mark Bjornsgaard said the company would also refund the leisure centre's electricity costs for running the "digital boiler" - and seven other England pools had signed up to the scheme.

The concept, developed over five years, is relatively straight forward - the hot oil is pumped into a heat exchanger to warm the water in the pool.
