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

there is a mechanical way of transfering energy to a pendulum

search the web for "BOTAFUMEIRO" in use in the church "SANTIAGO de COMPOSTELA" in SPAIN
there is good explanation on the web

A most interesting post indeed, my thanks also.

Go to that middle link and set up the flash animation as follows...

http://www.sciences.univ-nantes.fr/physique/perso/gtulloue/Meca/Oscillateurs/botafumeiro.html

Sine = on

vitesse angilainee = 1.7 omega 0

C de F = .04 Hz

with it running, grab the incense pot with the mouse and bring it up along side the
wheel... wait for the exact moment when the string to the pendulum is longest,
that is wit he the small circle closest to the pendulum pivot point... and release the
pendulum from the mouse...

It should run at over 90?, note this is from the perpendicular and is a total of 180?

Now we can see what the men pulling on the ropes are doing... they are shortening the rope as the pendulum swings down and releasing it as it flies up and out.

This is a "brute force" method of adding input to the pendulum and is not advantageous to our application. It does illustrate a principle of operation that in
our case the secondary beam is lowering the pendulum and thus lengthening the swing of our pendulum at the wrong time. This is a loss situation for our pendulum.

But it is interesting to speculate, once we have mastered this principle of shortening
the pendulum arm length on the down swing, on the development of the doubly
articulated pendulum, such as the "JHULIA" device. Most interesting....

Why complicate it, Ron?  The energy is already there in Jhula without messing around with the pendulum arm length.  Simply lock the relationship between the balance arm (counterweight) and the pendulum whenever the centre of mass is in a beneficial location and unlock it when it isn't. Look at Jhula again and tell me if I am wrong.

prajna,

I looked at the link but I did not understand what was on the link... simple as that.

I looked at it again and must confess the concept is still beyond me....

I must admit, I nearly noticed it many times before with designs for bessler type wheels but it just didn't click.  Then I modeled the Mikovic system and thought "so what happens when you unrestrict the movement of the lever?" Doing so created the kind of chaotic movement that you see in the animation, and I watched it and watched it and I began to notice that there are times when you just want to 'lock' the pendulum to the counterweight because you know that will increase the speed.  Obviously, the pendulum would need to be released to swing again after it had added to the momentum.  It seemed that it would need some complex logic to figure out when to latch and when to unlatch the pendulum but I watched and I watched and I just knew that if I could sit in the pendulum I would know when to latch and unlatch.  And then I noticed that if I wanted the system to rotate clockwise then I would latch the pendulum as it was both a) to the right of the system and b) not moving with respect to the counterweight (if I was riding the swing I would feel weightless).  I would unlatch it when it reached the bottom of the cycle.

I will do some more work on the site so that it gives more opportunity to understand what I'm talking about.  You have to watch the animation (best is to load the wm2d model) untill you have a 'feel' for the relationship between the pendulum and the counterweight and then suddenly it will click; you'll know exactly what I am on about.  Anyway, I'll work on some more drawings that show the difference between a version that is free to rotate (as in the current animation) and that same system where the pendulum is locked with respect to the counterweight.

Once you see how it works it is so obvious that it is difficult to remember how much effort it took to notice it.  Rather like some optical puzzle that takes a while to see but once you have seen it you wonder how you could have failed to see it before.  Thanks for reminding me that it is not easy to recognise.  I'll do what I can on the web page to make it more obvious.

i think i understand.
the pendulum locks itself after its first swing causing the massive lever to have enough kinetic energy to unlock the pendulum and give it a little kick to its initial position. a little circuit work maybe for timing? just a guess.
