vacuum, there will come a point where the vacuum is no able to lift
any more than the 100 lbs that it could possible lift,
theoretically.

Perspective matters, especially when the purpose of acquiring
knowledge is to apply that knowledge in technical contexts.

Well, I guess you've stopped someone from trying to put a V8 on their
vacuum cleaner

Maybe. There are plenty of people everwhere who think that it should
be possible to build a super vacuum if they simply make the sucking
power of the motor great enough.


Hey, you suck, give it a go.
