But if the water is sucked upwards by the vacuum and then the door is closed, wouldn't that be like halfway-starting a siphon and then placing your tongue over the hole? The water would just stay put until you return pressure, or something....I'm not a physics buff. I just know what I know though practical mechanical work, so I could be entirely wrong about the water even being able to be drawn upwards such a distance.

It would create a column that would collapse back down when the hatch is shut. The other side would just store the air, though I'm skeptical how much water one atmosphere of air would be able to move.

Simply opening the hatch isn't going to cause the water to do anything except slosh around when the air blows out.
I don't even think the air in side the container would react all that much. I mean the earth does a pretty great job of holding it what difference would building a container around it and them opening a hatch make? You'd have to physically pump the air out of the container and then you'd have to pump air back in, which requires workTurkey, am I completely wrong headed here?

The pressure required to shoot a column of air, let along a column of water, out of the atmosphere would be insane. The pump itself would nullify any energy generated by the turbines.

Physics experts please help explain why this wouldn't work
