it's really a shame they're not even trying to be creative:

for example why not use the heat to pasteurize milk? co-locate the miners with the pasteurization plants

even better: desalinate water to steam, use the steam to heat the milk and the milk to cool the steam, now you have desalinated water AND pasteurized milk...

but oh no, that would actually create a job for a couple of people to work it out and change the plants and negotiate and discover similar opportunities...
