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

In the Milkovic example, the pendulum is not damped by the load, and so it can be fed back.  Unfortunately, Milkovic's device is not properly designed so it will not be able to function in this way.  We have to alter it!

So, what is your suggestion how to alter it?? How should we redesign this pendulum-lever system?

Actually, it is not just the transfer of leverage.  It appears this way because he is using a lever.  If you keep the pendulum's pivot point stationary, there is no damping other than friction of the pendulum. 

The main point I see in this device (even if implemented wrong) is that you are RE-using energy stored in the pendulum. Assuming the pivot point does not move, the initial energy placed into the pendulum does not leave the system.  Friction produces energy "radiation" so that you must maintain a small input of energy to stop the pendulum from swinging down. 

Now lets say you alter Milkovic's design so that the pivot point does not move.  Gravity will try to take the stored energy in the pendulum and change the frequency of the pendulum across its period.  So that starting from a 90 degree position (90 degrees from the rest position) and moving to the 0 degree position (0 degrees being the rest position), the frequency of the pendulum will shift from high to low.  From 0 degrees back to 90, the frequency shifts from low to high.  This happens at twice the frequency of the pendulum, so that the system functions as a parametric oscillator.  The only energy being lost here is friction.  Placing a load properly on the altered Milkovic design will only stop the pendulum's frequency shift, allowing the pendulum to swing at a constant frequency equal to the frequency at the 90 degree position.  The average amount of energy required to keep the pendulum swinging is the same whether the device is loaded or not. 

From the standpoint of energy input/output, it should take less input than the output because if you ignore the initial input to lift the pendulum to the 90 degree height, the energy to keep it swinging is much less.  Since the pendulum is not damped from the loading, it may be possible to feed the energy back to keep the pendulum swinging.

This will not work because the leverage is directly effected by the counter force produced when the coil is loaded.  So it will become harder to push the magnet through the coil.  In effect, the lever system is damped, regardless of leverage. 

In the Milkovic example, the pendulum is not damped by the load, and so it can be fed back.  Unfortunately, Milkovic's device is not properly designed so it will not be able to function in this way.  We have to alter it!

Haha, that's a good question.  I have no idea!

IT is false !!
very bad science !!

It is damped by the load.
When at the lowest position, an ordinary pendulum mass has lost its potential energy. It can regain it by continuing its movement and transforming again its kinetic energy into potential energy, by moving up to the same height it was starting from.

But the Milkovic's pendulum is different. When the pendulum mass is at the lowest position, the fulcrum is at a lower position due to the movement of the lever. The pendulum mass has lost a supplementary potential energy. In order the pendulum mass to regain this potential energy, the lever must raise again the pendulum fulcrum by restoring the energy it acquired from the lowering of the pendulum mass (that one due to the lowering of the fulcrum). If energy is consumed at the other end of the lever, the lever will lack energy to restore the position of the fulcrum at the same height.

The Milkovic's pendulum is really a parametric pendulum with a pumping function. Nevertheless in such a system, the energy is always conserved, it is just shifted from the pumping system at the pumping frequency to the pumped system at the pumped frequency (for example, search for "parametric amplifier". http://en.wikipedia.org/wiki/Parametric_oscillator. They were used in the 60's to amplify SHF signal received from big parabolic satellite antennas, by pumping a variable capacity of an oscillating LC circuit and thus transfering the energy from the pumping frequency to the signal frequency).
