Pressure based idea

[tbird]

tbird,

Yes, it is pulled out.

then if you have a total vacuum to outerspace, the water will rise in the tube to about 32 feet (the amount that can be lifted without cavitation) where it will boil (as hans says). 

i doubt if you could ever get a vacuum in the tube because of the water's constant boiling.

maybe you need a different example.

I agree with hans that water will boil if it lifted in the way I draw it. If we decrease in my
pictures the height to e.g. to 8 meters and there is no empty space on top of jar.

Now if the water don't boil with this modification I still don't understand how the hydrostatic pressure
behave in this situation. And in my last drawings I try try figure this out.


ps.
In first pictures this modification means that the pressure tank will be 8 meter and the pool must be
decreased also e.g. to 5 meters. This means that there will be less pistons in the machine and of course
this will also change the pressures used in machine. But still the main idea remains as same.

that guy should rewrite the explanation.  he seems to be confused himself.  he says;

""Therefore both of these devices should turn counterclockwise""

referring to the first design under "Buoyant Wheels and Belts", even the arrows show a clockwise direction.

with statements like that, how can anyone follow what he is trying to say?  even if he is right, you wouldn't know it from his writting.

edit: 

"During this time, air is forced upward through the tube from the bottom piston to the top one. The piston chamber at the top gains a volume of air V. The one at the bottom loses a volume of air V."   

clearly he doesn't understand how this unit is designed to works.

@ t bird,

There you will find his email and can point out the error to him. I am sure he will be happy to get it right.

If a mass is hanging from a string and it is at the level of a surface below it, will it EVER have the ability to exert the full force of its full weight on BOTH the string and surface at the same time?

Extra credit:
If that straw full of water being held up by a thumb over the top has a normally buoyant object placed in the bottom of it, will it rise in the straw?
How about if the buoyant object is already in there before the thumb is placed over the straw?
