Hydro powered air Compressor (not a trompe!)

Pictured below is an air compressor that is basically a ram pump with a piston rather than a check valve pump. I call it the Hydro-ram Compressor.

The smaller piston dives the larger piston which allows the system to compress more air by volume.

If designed well it should compress more volume of air than volume of water that drains per cycle.

The force of compression is created by the mass and velocity of the water, by the length of the piston, and by the volume of the compression chamber.

This could be used to run an airlift pump. Because air lift pumps can operate at a 1:1 ratio I believe that the entire drainage can be lifted to higher ground without depleting the air supply which has many uses. 100% of the water drainage could be pumped up using this process, which makes it highly efficient.

I believe that the combination of these two devices could be used to create an endless supply of compressed air (when running water is not present) by returning the drainage to the source via the airlift pump.

The energy source for both of these devices is gravity and thus has limitless potential and it does obey the law of energy conservation.

Terry Frankelburger : I think that this is case where I am miss-fileing My assumptions of what you are trying to show me and because of that, I am missing some thing !

For every 33 ft of fresh water available to create 'head ', we gain ~ 14.7~P.S.I. so with 100' of head we will be close to 44 P.S.I., Why wont this stall out then, and where are
you getting the Air that you are pumping ! Sorry, I must be comparing apples to lug nuts, but I Dont get it ! Big Al !

Big Al: The compression chamber has check valves that allows air in and compresses the air out out and into an air tank, these are at the blue arrows.
Also this system utilizes the pulsating flow of the ram pump and not the head. It uses none of the attributes of a trompe. When the flapper valve opens water flows and gains velocity. When the valve shuts the force of the descending flow of water is diverted at the tee to drive the piston up and compressing the air in a different compression chamber/piston. the acceleration of the piston will be much faster than the water which will provide proportionally higher compression (psi). When the flow stops the flapper valve will reopen and start the process again.
As you said apples to lugnuts.

Are you suggesting that this system could continue in a loop, using the same water over and over and that there would be some sort of net gain in energy that could be drawn off? If so, and you produce one that works to my satisfaction, I'm willing to pay $100,000 for a 1% stake.

Dale: From what I remember of physics and from what I have read regarding air lift pumps this is possible but to what degree if any I could not say because I am not sure as to the validity of my sources on air lift pumps. I can say that even if you can lift 50% of the drainage this is more efficient than a ram pump. As for the $100,000, although it would be worth millions I would not even consider trying to profit off from free energy. I believe free energy should be for everyone.
I am going to try to build this even just to disprove myself but at this time I am not able to. I still have doubts that it will work with 100% return.

Ok after considering the efficiency of this according to Kinetic and potential energies I am certain that it will not return 100% of the water to the source. I am a bit embarrassed that I even thought it possible.

I am not even sure that it will lift any more water to any given height than a ram rump but I am certain that it will compress more air to a usable pressure than a trompe without the need of a large head. This is significant because compressed air is extremely useful often serving more than one purpose simultaneously and this would also be cost friendly to build.
