vacuum and gravity powered siphon

[sticky]

hey folks a freshman here with an idea similar to the well known space elevator theory,
if a tube could be laid from space into the sea, could the power of vacuum alone pull the water as far as space, or if not the vacuum of space, could anything? and if that was accomplished, another tube leading back to the sea would allow this water to fall back to earth by the power of gravity, powering turbines on the way. If the system was started would the water flow perpetually as in a hosepipe when you are siphoning some petrol from your tank!!?

would love some input of some kind as im sure the idea is full of holes id just like to know if im still sane!!!! well it seems im only remotely sane i know now the vacuum wont work, but could anything get the siphon flowing?if the water could be kept in a liquid state.

Its' very cold out there  something like -300F

the maximum vaccume potential of water is 33.1/3 ft. at sea levil, This means that you can only lift water just over 33 feet with a vaccume.

Without looking it up, I recall somewhere around 52 feet.  Same order of magnitude.  Moab speaks truth.

The space vacuum tube will not suck earth water into space.  Gravity overcomes this tendency.  Take away the tube and we already knew this.  See all the water still on earth.

Any planetary body with gravity weak enough for this idea to work would have lost all of it's water to the vacuum of space long before we arrive with our tube.
