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

Only the large horizontal arm (also a pendulum with its own oscillation period) is replaced with a spring pendulum on the right side.  add a spring to the bottom of the right weight, we get a spring pendulum instead of a lever one.
Only I do not understand why all this, if the device cannot be self-energized.

p.s.

With some kind of ratchet on the cable it could be used for lifting.

I have shown that even without the ratchet, as long as the pendulum continues to oscillate of sufficient intensity, the heavier weight goes up! When the swing stops, it goes down.
I really don't know why ...
Is the energy of my hand pushing the pendulum converted into lifting a load?

There is momentum in the upward movment of the not swinging weight.

Energy is stored in the pendulum swing, but also in the upward momentum of the
lifted weight.

If the pendulum swings again, before that upward momentum is expended
then the lifting by the pendulum will combine with that upward momentum.

The lifting can become continueous but also speeds up and slows down / is jerky.

Its not O.U., its energy storage.

The age of hero worship is past.
A president is just management.

There was no massive election fraud during the 2020 presidential election.
That was a lie.

What kind of man is Donald Tump, to promote such a lie, when it is so
destructive of democracy ?

We are under a psychological attack of divide and conquer.
Don't buy into it.
Hate is not the solution.

Adding a spring is a cool idea. 

A spring will also store and then release energy.

This can improve the timing between storage and release of the energy,
make the timing of the pendulum swing less critical / extend the time period
over which energy is transferred.

Milkovic did not invent the pendulum on a lever device.

Black smiths sometimes used this kind device for their hammers
more than a century before MilKovic was born.

That a pendulum can be more efficient than a continuously rotating device in
some applications ? This has also been know for centuries (example, clock pendulums).

Milkovic deserves credit for bringing it forward, examining and repoplarizing (marketing)
the method.

But it is not a free energy device, as far as any one has proven.
