Re: Déjà vu
Indeed.
I once had the opportunity to go do helpdesk stuff in a warehouse that stored milk products (ice cream, etc). It was cooled to -30°C.
It was in winter, outside temperature was around 0°C, but sunny. I spent all of twenty minutes there.
When I left the place, I had to take my coat off. For a few minutes, I felt like I was on the beach, what with the sun and all.
Of course, 0°C caught up with me pretty quick and I put my coat back on after a few minutes.
Still, I don't think there'll be a lot of helpdesk people poking around racks that are cooled at 4.7°K.
I can't imagine the amount of energy that is going to be needed to cool an entire server farm down to that point.
