12 times more output than input, dual mechanical oscillation system !

Well the input power is not very much so you do not get that much out either.
Yes I agree with you, the energy needed to create a large amplitude in the string is large, but still it dies out almost immediately. The energy into the pendulum isn't very much but it does last a lot longer, and it does put out some work to move the air.

Now here is an experiment to think about, and it is probably more correct than the demonstration shown; take that paper and attach it to the pendulum instead. Now compare the air moved against the time it can keep moving. Then you do the previous experiment, with the paper on the string driven by the pendulum. I think this will show the difference between the two ways of using oscillation power better.

I haven't read this entire thread, but does anyone have any ideas on how to close the loop MECHANICALLY for proof of concept?

[TechStuf]

The preferred way to close the loop, while extracting useful work, would be to devise a rotary system. While it is certainly possible to build a perpetual pendulum, the swing periods of themselves, do not create enough centrifugal force from which to reduce the required power.  Even a rotary system itself, would need to be of appreciable scale in order to extract advantageous power output.

When such a rotary system is evidenced, the greater possibilities may present themselves, as G force can be greatly amplified artificially.

Techstuf, I have such a rotary system idealized, and much more simplified and efficient, but the truth is that I really suck at doing mechanical work. My biggest obstacle for the project is cleaning and lubricating a ball bearing

But the rest of the design is really straightforward. I have just removed myself from advocating this idea because of my own restrictions, but maybe someone could help me with it or even try to build what I had in mind? It doesn't require very much, and the whole thing was supposed to be "glued" together by epoxy.

Well, you've come to the right place!  I can put you in touch with Steorn straightaway....

lol

As for your epoxy troubles, might I recommend Finsrud, as I'm sure he has overcome his difficulties!
