Microsoft to dump it's computers into the sea.

I'm a whole lot more concerned about environmental impact than feasibility.

Yeah that was my worry as well.

Some of them are going to leak in big storms that are more likely given climate change. The sea is a corrosive and hostile environment at the best of times.

Saying that, the casing will need to be brought up again if only to replace all the computers once they become obsolete.

And saying that it will only increase the water temperature by a millionth of a degree is disingenuous because the whole point of the experiment is to see if it can scale up.
