Johnny:

So, you reported me to Stefan?  Did you also tell him about your threatening to take away my license to do business? (Which I don't have, but, no matter, reality is what it is)  Did you also tell him about all of the made up stuff you are saying about me?  Like my deleting your posts?  Quite an accusation to make...a very serious one I might add.  Also, to make that to Stefan who KNOWS I am not a Moderator here, is laughable.  Stefan KNOWS I can't delete pm's, emails, or posts here but you persist in accusing me of doing so.  I take serious offense to that and am considering my legal options at this point.

I have never said ANYTHING about anything you have built....mainly because you have not built anything and....also, because I do not care what you do or do not do so long as you are not insulting me, or others here on the forum.  You can not quote anything I have said about your builds....ever.  Read my keyboard....I DO NOT CARE.

Stefan is on holiday in Europe at this time and I will not bother him with this crap until he returns.  My advice JIM (Not Johnny)is to grow up.  And, if you can't do that at least....shut up and quit insulting me, and other forum members here.  You are working yourself into a legal action very fast, which you can then add to the reasons why you can't build anything.

I told you I am not screwing around any more.  You threatened my business and now accuse me of deleting personal information.  That IS a crime.  Look it up.

Leave me ALONE!

Bill

PS  I qualified as a Master Machinist back in the 80's and when I compliment TK's work, it is because it is good, not to insult you.  With what you posted, it is obvious you know nothing about precision work or machine tools in general.  The most accurate work on the planet is done by hand and by eye.  Otherwise, you could never use a machine to build a more accurate machine than the one you started with.  Understand?

  deleted post. Will wait for Stefan to consider the misconduct I have been subjected to.

I would recommend reading up on pascals law and hydraulics. None of the ideas presented here will work.

For example the submerged container will only push liquid up to the height of the water and not 1 mm more. having air in the container does not make any difference.

Hydraulic pressure will raise the air pressure in the container to match the surrounding pressure in the water. so you can dispense with the air. And if you don't need to have the air then you can dispense with the container and just have the pipes.

From that you should see why it wont work.

The trick to understanding hydraulics is understanding pressure. In a liquid the pressure is even in all directions. What this means is you only need to take into account the pressure exerted by the column of water directly above the point of interest.

In the  submerged container idea the only pressure that matters is the pressure directly above the inlet pipe and the pressure above the outlet pipe. They become exactly equal when the water in the outlet pipe rises to exactly the same height as the water column above the inlet pipe. e.g. the surface of the water.

Read up on Pascal's Law
http://en.wikipedia.org/wiki/Pascal%27s_law

After studying pascals law you should understand that the only way to get water to spurt out the outlet pipe is to raise the height of water above the inlet pipe. This can be done by creating a wave. as the wave passes over the inlet pipe a small amount of water would be ejected from the outlet pipe but only to the height of the wave. This would only work if the container was sealed and solid.

study hydraulics, its a fascinating subject! Once you understand how a hydraulic jack works and why it works everything else starts to make sense.

With respect to Johnnies trick video

Nicely done.

This is what I think has happened. Clearly there is two separate areas within the main container each has a separate volume of water in it.

The container is then sealed. Either air is blown into the container to increase the pressure or a trick is used. The container is placed in a fridge unsealed until it cools right down. then the container is sealed. as the container warms up the air in it expands creating pressure.

So why are the water levels in the two pipes different?

Simple! The air pressure inside the container is constant, but the size of the pipes is different this means the RATIO of the internal air pressure to the external air pressure is different therefore the fluid height is different in each container and pipe.

The two areas inside are to allow each reservoir of water to maintain a different height. if it wasn't separate, then the ratio of external to internal pressure would be the same. I.e. the diameter of both pipes are simply added together.

Again I implore an investigation into pascals law and hydraulics in general.

  Chris,
Heron's work goes against some modern conceptions of hydraulics. He has 2 different pressure heads reacting differently to the same stimuli or air pressure.
