I offer close loop with compressed air. If such system can run by itself, then we have overunity. If pressure rises, this energy can be used for other purposes.
Can someone make calculations? Or may be a real model?

Thanks for submitting your idea. That is good, but in my opinion all ideas should be based on technical experience. Or at least you or someone else (who is skilled and equipped enough) should try it in practice.

Interesting result using Working Model 2D.
Air Resistance set to High.

Still, unless someone like Andrea is interested ( she has a build ). When she gets her build working closer to what she likes, who knows, she might give it a thought.
 

I'm a boy not a lady...  in Italy Andrea is a boys' name. Bye!

England is closer geographically to Italy than to the US ;-)

Raymond, I was thinking of saying this to you before, but now I just have to: you will have to watch your back! This is really a kinda big deal, I'm sure you know. Even if it isn't some big conspiracy, there's all kinds of people out there, and some might just be really furious on you for trying this, even if that seems weird.

Don't worry about the math or the physics of it, I am quite certain that this is understandable when we include more advanced physics, together with what I think is the core of its operation; the parametric resonance.

It will be very interesting to hear how your effort goes, if it goes well, well then a lot of people here will have to admit that they were wrong

 Before anyone gets too goo-goo about this machine I suggest they inspect the design of the ancient Chinese spoon-tilt hammer.  This new design is basically the ancient one with a twist-the pendulum, which means nothing but that it is a variant of the original.  It is also similar to other ancient machines like the Oliver (treadle hammer), and the Shadouf (Swape).
 There is a book M.I.T. press has for sale called 'Simple Working Models of Historic Machines' by Aubrey F. Burstall  ($20.00) that has examples of each of these ancient machines.
  A slight-of-hand may be at work here.  Shields up!

Hi Russell;;;   I really like the way you put that. 
"This new design is basically the ancient one with a twist-the pendulum, which means nothing but that it is a variant of the original."

Like the F-!4  Tom-cat is basically the ancient one with a twist-  better aerodynamic design, Aluminum Alloys, and jets that can produce many more pounds of throust per pound of engne weight.instead of the old prop planes.
I am with you all the way Buddy.  There is nothing new on this earth.  Only improvements to old ideas.
Purly for the sack of discution.  Let us say. The machine does not put out more energy than is put in.  AND, At the same time acknowlage the given Fact that it operates Exactly oposet of every other machine on this planet. In that the more resistance is put on the machine the easyer it is to operate.  Would this not mean that there is "A POSSABILATY"  that it just might, or could be,  THE most effeciant machine ever designed to this date.
I proposs ;;;;;    IF; it is possible. Then it is worth my time to look into. And any constructive sugjestions you could come up with would be welcomed with OPEN arms.
I honestly say to you. Your sugjestion that this may be an ancient design with a twist- the pendulum.   This thrills me to no end.  For IF, the pendulum is an improvement on the old design.  Then maybe we need to improve the penduluim next.  And seeing as the pendulum has been around for some time now.  Maybe it is time to think 'IMPROVEMENT" of the pendulum.  As I have stated in one of my videos. We have redesigned the pendulum to reduce air friction by over 95%. And when we can afford it ,  all bearings will be tefflon coated.
I tell you now with 100% knowlage (not thiory) anyone that is not sure of this machine or has second thoughts as to wether it works or not. Has not  operated one with his or her own hands.
I wil now formaly give an OPEN invatation to every one in this forum that has second thoughts as to this machine, to come to my home and try it out for yourself.
