A plan to use waste heat from supercomputers for salmon farming is underway in Norway, and waste heat from data centers in Japan is also being used for eel farming.
Norway is currently working on the development of its most powerful supercomputer,

Olivia is a supercomputer jointly developed by HPE and Sigma2 , a Norwegian research institute. It uses AMD's Epyc Turin CPU with a total of 64,512 cores and 304 NVIDIA GH200 GPUs.
Olivia is installed in the Lefdal mine data center in northern Norway. Here's a bird's-eye view of the area around the Lefdal mine data center. From the outside, it doesn't look like there's a data center there.
There is a vast space underground.
Below is a photo of the interior. The strict gates and pipes make it look like a secret base.
There was enough space for a large truck to pass through, and Olivia's parts were transported in by truck.
The building where Olivia is installed is below. Olivia's main body is installed on the first floor, and a space like a conference room is set up on the second floor.
Olivia is designed to be both powerful and energy efficient, using renewable energy to reduce carbon emissions. The heat generated during computing is cooled using a liquid cooling system, and in the future, the heat generated during computing will be reused for salmon farming.
Efforts to 'use the heat generated by computers for eel farming' are also being carried out in Japan. For example, at the White Data Center in Hokkaido, water heated by the exhaust heat from servers is used to farm eels. You can see inside the data center and eel farm in the video below.
