Yeah I remember that post, it was a good one. I'm not saying that it's impossible. Just: does it make actual economic sense as long as we haven't even really started building vertical data centers? We're still very much 2D and Microsoft's latest "super data center" (#1281419) has been lauded for z{1..2}.

True. I was surprised that the second floor was notable.
Perhaps when there's an advantage to gathering raw materials and manufacturing GPUs/ASICs and solar panels in space, this kind of thing makes more sense.

If we’re going to use chips in that package, we need to spread that heat. Roughly speaking, we need to spread the heat from a 1cm2 area to a 80cm2, or a circle with a radius of 5cm2.
That's a factor of 80, how do you get 6400?

area = length * width

You're saying 80 cm^2 is 6400 times the area of 1 cm^2?

oh lol you're right. i read that as "1x1cm and 80x80cm" rather than 1 and 80 square centimeters. i don't know why i did that.

Good catch, I somehow glanced over it and in my mind did @k00b's (wrong) explanation below too.
