Re: Space Elevator/Pipeline for Titan

: A much better one would be to stick the tubing in the Mmercury. Then stick
: the *entire thing*, cup and tube and all, in a vacuum chamber. Evacuate
: all the air. Does the mercury then start to climb up the tube? Of course
: not.

Hm. Well, depends on how you dip the straw into the atmosphere.
Suppose you construct the straw in vacuum, close a valve on one end, and
insert the closed end through an atmosphere and into a pool of liquid.
Now, open the valve. Does the liquid rise up the tube? Yes. How var?
Ten meters or so at most (in 1g; proportionally higher in less gravity).

If you dip the a straw, open and both ends, into the atmosphere and
into a pool of liquid, it would rise zero meters, because as you were
dipping it in, it filled with air (or whatever you want to call the
gases above the liquid pool).

I was assuming the former model.
