alt Hacker News> The computer contained about 18,000 vacuum tubes, which were cooled by 80 air blowers. More than 30 meters long, it filled a 9 m by 15 m room and weighed about 30 kilograms. It consumed as much electricity as a small town.
Surprisingly light though...

An obvious typo. It was tons, not kilograms.
Perhaps AI aided?

The vacuum in the tubes weighs nothing, so they produce lift.
I still remember the CRT TV we had at home when I was kid. It was big but almost empty.
Vacuum tubes break too often. Once per year? But if you have a thousand of them you have to change one very often. So I guess they have a lot of space for humans repairing it.
