2-Stage Oscillators and the Quest for “Free Energy”
It may not look like much, but Serbian scientist and inventor Veljko Milkovic will tell you that under ideal conditions his two-stage mechanical oscillator will produce twelve times more energy at the business end of the machine than what is required at the input side of it.
[After spending several days reading the documents and opinions, watching the videos, and making myself comfortable with the material I link to below, I was sufficiently convinced that the 2-stage oscillator was—at the very least—something CleanTechnica's readers would find interesting. I welcome your comments and critique, because that is how science progresses -TBH]
Simply put, the two-stage oscillator consists of a lever and a pendulum: two machines that perform work individually. Milkovic and others claim that when these two machines are combined, assembled with the proper weight distribution, and properly synchronized, Centrifugal and Gravitational forces operate in concert to produce energy gains bordering on the astonishing.

“This certainly ranks as one of the most important discoveries in science in the last 300 years,” said Peter Lindemann, who suggests the twelve-fold increase in power at the output end (pdf) appears to violate Newton’s Third Law of Motion: For every action there is an equal and opposite reaction.
Once the optimal speed has been reached by the swinging pendulum, Milkovic postulates that very little energy is required to maintain it.
Greatest impact could be in developing world
There have been several iterations of the Milkovic design and it is argued that the mechanism could be used in automatic hammers, transmissions, motors, pumps and more. In theory, the design could be scaled up to handle much larger amounts of energy — even utility scale.
But one of the most viable and “shovel-ready” applications of the mechanism is in manual water pumps. Widespread diffusion of appropriate technologies like Milkovic’s two-stage oscillating pump could have important implications in parts of the world where manually pumping water is a fact of daily life. (Watch a video of a water pump with two-stage oscillator).
The search for perpetual motion machines and “free energy” has occupied the minds of mechanical engineers for as long as there have been mechanical engineers. And while there have been the standard methodological challenges to the accuracy of certain measurement tools and protocols used to study the two-stage mechanical oscillator, Milkovic’s design has yet-to-be understood implications for a world with constantly-growing energy needs.

In the video, the only energy that is being done by the machine is the production of noise and some heat. The energy required to do the work of lifting the weight is returned to the system when the weight falls.
If you move the pedulum so it just struck the side of a metal barn, you would get a very loud noise with a modest input of force to maintain the swing.
If you want to say, “isn’t this an interesting looking way to crack walnuts”, I might agree. If you are talking about getting more energy (not force) out that you put in, I am afraid you are confused.
Contrary to the addendum above, Timothy Hurst does not welcome your critique. I have made two civil comments critical of his reasoning and both were subsequently deleted. Unbelievable.

There is no such thing as centrifugal force.
The term some earlier posters are looking for is centripetal.
Basically, centrifugal force “feels” real, but isn’t.
From wikipedia
“Common misunderstandings
Centripetal force should not be confused with centrifugal force. Centripetal force is a kinematic force requirement deduced as necessarily present if an object is to track an observed trajectory. It is not a kinetic force like gravity or electrical forces. Centripetal force requirements may be deduced from a trajectory in any frame of reference (although the trajectory of an object and the deduced centripetal force will vary from one frame to another). Because centripetal force is a kinematic force requirement inferred from an established trajectory, it is not used to deduce a trajectory from a physical situation. Centripetal force is therefore not included in the inventory of forces that are used in applying Newton’s second law to calculate a trajectory.
Centrifugal force, on the other hand, is treated in a rotating frame as a kinetic force – it is part of the inventory of forces used in Newton’s second law to predict motion. Centrifugal force is a fictitious force, which arises only when motion is described or experienced in a rotating reference frame, and it does not exist in an inertial frame of reference.[4]“
I went to his web site and watched alot of videos, it does make work alot easier. Pumping water out of the ground can be done with one finger with little effort, it looks like a great invention, it will make life easier. I can’t believe no one ever thought of this before.
This is just one of the stepping stones you are going to see in the Energy Revolution we are entering. This device will not be powering vehicles directly but I can see them as personal power stations for generating hydrogen for fuel cells. I see alot of Scoffers out there pointing fingers at this pendulum device and other devices. But this is normal, for every scientific acheivement that has changed mans life for the better there are scoffers. The more scoffers there are the more dramatic will be the effect of the device on our life. Just look back in time at the trains,planes,rockets etc. if the scoffers had their way we would still be ridding horses for our main transportation. Walt
In the olden days the TOP scientist of the day argued that if you went over 30mph on a bicycle you would suffocate. This stubborn stupidity is the same for some of you people - the term I would use is intelligently stupid.
True Perpetual motion indeed cannot be! This device however is not a perpetual motion device. It is a gravity to ‘useful’ work converter. No laws of physics have been broken here. It is just how you have chosen to interpret the English language.
Some may scoff but everything about the universe (planets, solar systems, galaxies) that are moving because of this force would scoff right back at you.
To be able to understand this you are going to have to think for yourselves and not blindly follow the texts books and what you have been told lie a sheep - be an actual scientist!
In a nutshell……
The part of the machine doing most of the work (where the extra energy comes form) is the side with the free weight. The pendulum is mealy a switch. A small input energy is needed to keep the pendulum swinging (to counter friction).
At rest the seesaw is balanced.
From a basic understanding of physics you should know the pendulum virtually weighs nothing at its highest point (it is neither going up nor going down). When this happens the see saw tips to the other side (this is when you get the extra energy).
At the pendulums lowest position it becomes heavier than the other side – due to centrifugal force. Therefore the seesaw tips back. However does not have time to completely tip as the system is re-gauged.
Having successfully built and tested these devices myself, I can tell you that it is not as simple as the drawing would suggest. If you are attempting to reproduce the experiments you definitely need to be able to adjust your weights and timing and you also need a good and sturdy build quality.
Have fun and may true science triumph!
