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

I was going to build a large scale version with a LONG pendelum on my kids swing set same as the small Spring wire version, But 1 problem is that i cant find anything springy that will support its own weight (and a pendelum) at that sort of length.
But i was just looking at the documents again and see that there is a first class lever design there. That i can build with a counterweight.

anyway i can explain  where the energy goes. i think..

  This is using the spring wire 3rd class lever design.

  The pendelum is affecting the lever(wire) even when the wire does not appear to be oscillating. Because the pendelum at the centre of its swing has more downward force. At 90 deg it is almost weightless. This causes the wire to oscilate up and down twice per swing. (even if you cant see it) and this is a classic 3rd class lever

Now the oscillation in the wire is caused by the up and down movement of the pendelum.  Because the wire is long you get a wave oscillation effect. If the wire was short it only oscilates twice per swing.

OK here's where you lose energy..  The up and down movement of the pendelum is absorbed by the spring wire.... 
Try this... get a piece of string, tie something to the end of it and swing it. Now move your hand up and down. You can either make the pendelum move faster or slower(stop). When you make it slow down you are absorbing the pendelum energy.

This is the same with the piece of wire it moves up and down, pretty much in sinc with the pendelum, but it is absorbing the pendelum's energy.
If you stop the wire from oscillating the pendelum will swing more efficently.

I think one misleading point of the viedos is that they show HEAVY pendelums on a short swing.  But you can see with the torches video they have to put alot of effort into the swing to keep the thing swinging.

Not much can be concluded from the video since we don't know the technical aspects of it, for example, how do we know that the pendulum weighs like 50 kg and the hammer only say 5 kg

One of the obvious things about this set up for being able to evidence the phenomenon discussed is that the pendulum has to be in balance with the lever, so if the pendulum side weights 50 kg the lever side has to weight 50 kg. duh.

Not necessarily... Its now my belief that the hammer end of the lever might actually be slightly heavier to help match the pendulums phase. Basically it allows for the hammer to only be lifted when the pendulum is within 10 degrees of vertical. I have found in some simulations this slight imbalance allows for the system to run longer in phase while still allowing the pendulum to match velocities with its control pendulum. This means the pendulum is doing more work then when I was balancing the lever but runs longer and with more efficiency. As I have said before there is still lots to understand hidden in this seemingly simple device. Right now I don't have room or time to start working on a physical replication, but in the coming year I hope to start work on it.


@ all the naysayers
I have a challange for you the same I've issued to everyone. Download WM2D and do a few simulations where you have 2 identical pendulums one on the lever and the other running independant as a control for observation. Then add a damper to extract work. You will sooner or later find what I found which is examples of first law violations. The simulations and my hypothysis may be right or it may be wrong, but at least I'm testing it thuroughly before dissmissing it as junk.

Dingus- please post your w2md model for others to checkout.

General comments:

It occurred to me that one way to test the peak power output would be to pump water up a column.  The maximum height would give the peak-force.

To measure the power output, you would simply pump water from one reservoir to a higher reservoir, and measure the time it takes to transfer a known volume.  The energy gain is given by PE=mgh, and divided by time would give most of the power output (less friction in pump, flow resistance, compliance, etc.).  The water pumped gains the usable energy.  This would be more accurate than sweeping magnets past coils I think.

I think that the best way to measure the input power would be to actuate the pendulum electromagnetically, and just measure the electrical input power.  It could even be triggered by a manual switch.  Could also use one of those slick parallel-path designs.

If I were asked, I'd recommend closing the loop using a fluid-only system.  The pendulum could be driven by a water-wheel I think.

It's striking to me that the input force to keep the pendulum swinging is perpendicular to the gravitational force, and the work is being done parallel to the gravitational force.

I already posted this I think, but I don't feel like looking for it...

My spring line added kinetic energy to the pendulum, and beat matched it. (equal freq)
It also spun a flywheel with a rotational damper in one direction for over 4 minutes.

I'm planning on buying a legit copy next month, then I can upload the actual sims for you guys.
