A few years ago one of the fission reactors in Minnesota had to abruptly go down for unscheduled maintenance. This happened in the middle of the winter, and the part of the Mississippi river where the cooling water discharge entered rapidly dropped temperature (assuming dT~25degF). There was a la

1. We already do this for nuclear and other power stations. I remember visiting Fawley, an old oil fired power station in the UK, back in about 1982. Its cooling water was taken from and returned to the Solent. The increased temperature of the water made it ideal for growing oysters, and a co

Or a 'boiling the seas and killing every living being on the land' point of view. Remember: * the law if unintended consequences * we are in the Anthropocene era * Global data centres draw as much power as he entire country of Italy. This would be like throwing an electric fire the size of Ital

Listening in on the heated discussion of immersive cooling while I was sitting on the shores of Lake Superior this summer, I was reminded of a recent NYT article on Microsoft's Project Natick: http://www.nytimes.com/2016/02/01/technology/microsoft-plumbs-oceans-depths-to-test-underwater-data-ce
