It is obvious that is Milkovic's two-stage oscillator and it seems they closed the loop...?!

The energy imparted to the system by each push of the hand will exceed the energy needed to raise the water a foot or two.

This is a great breakthrough. I have played with one of these pendulum-levers enough to know that there is definitely an energy gain. Closing the loop is very difficult. I was using a rotary solenoid powered pendulum, but retrieving feedback electricity from such slow moving mechanism proved to be beyond my simple means at the time. Also, a stepper motor would probably have been a better choice, for electrical reasons.

The closed loop video doesn't show enough detail to get an idea of how it is being accomplished, but clearly the designer is a very clever individual.

this can be practically used for this pendulum oscillator

Inventory of the Veljko Milkovic 2 stage oscillator an efficient mechanical gravity assisted pendulum power device.

milkovic.JPG

The correct positioned mechanical parts allows a momentary condition,
the gravity deceases gradually as pendulum swings up causing dip in potential. Instrumentation (fish scale) load cell data acquisition log.
Getting the pendulum started has an initial force expenditure that becomes negligible when driven continuously (child on a swing).
Also a hammer jolt is delivered thru the metal from the anvil is* beneficial in opposite directions allows undamped pendulum swing.
Conventional observation shows that at the ends of the swing the pendulum is lightest and conversely the pendulum is heaviest at center.
As the pendulum gets heavier the cantilever increases lifting the massive lever and while metal relaxes on the other end.

As feasibility goes. Contending with political and financial control, large scale would be slow acceptance more favorable for non energy application.
Cost seems good considering how many solar panels it would take to give cost effective equivalent power.
because government/energy denying permission to construct and operate large large, a mid sized (400 lb ?) 2 stage Milkovic in the garage makes sense.
A large scale pendulum was built and tested however it was only a single stage pendulum.
The video comments: It;s time to return to gravity assisted power. Gov and energy corporations willing ?

to gain visual reinforcement of the motion starting with the pendulum.
in the video notice the direction of the hand.

The Milkovic anvil pulse may have similar relationship to constructive interference.
The frequency beat of the anvil having very slight difference in rate.
https://youtu.be/4M72kQulGKk?t=126

The mechanical drive of the pendulum derives its impulse from a catenary curve
applied to the pendulum arc at a slightly faster beat.
Approximate rotational drive mechanism rotated ccw 90 degrees:
507 Mechanical Movements, 374
Sketchup software can scale a catenary for correct dimensions of a roller cam assembly.
