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.

yeah, I really used to liked this site, but this article dissapoints me. The article shoud be tagged as ‘pathological’ science. Centrifugal force and homogenous gravitational field NEVER produce energy. Btw. this “discovery” is one of dozen at New energy congress - a pathological science site.
Guys… this is just a simple example of parametric resonance. No fancy new science to be found, and certainly no violation of newton’s laws. Like any other resonance phenomena, energy is stored over time in the resonant oscillation rather than being dissipated through processes. So, after several periods of the input, the output *is* exhibiting greater energy than is contained within any individual input period, because it’s been storing the energy from all of those input periods. Net energy in, however, still equals net energy out, at best.
I thought this blog had some credibility. At no point do they offer any science or even any question of the claims made by Milkovic. Is this an early april fools article or what?
Oh no!
Force does not equal Work (or Energy)
Author should fail his first physics course for this.
Wow … this is not even wrong … this is total bullshit !
This is hilarious… people should study their physics basic concepts before posting crap like that !
The world is flat! The world is flat!
At no point in the article do I, or any of the scientists I quote, claim that this is a perpetual motion machine. Looking at the animation only, I can understand why you might have that impression. What is not conveyed in the animation is that work needs to be performed to keep the pendulum swinging (the animation is, perhaps, misleading in that respect).
All I request is that you watch some of the videos and explores some of the docs I linked to in the post and open yourself up to the very *possibility* that this machine and its concomitant energy gain is plausible.
Tim,
Unfortunately, the claim is that the energy input is magnified 12-fold to produce the energy output. This claim is a violation of the law of conservation of energy in the same way as perpetual motion devices.
I’ve now watched the video, and I agree that it does, indeed, pump water, but it certainly can not magnify the energy input twelve-fold.
Further, the pdf you link to discussing the device as one of the most important discoveries of the last 300 years is written by Peter Lindemann, who operates the freeenergy.ws website, and lists no university as his alma matter. I hardly think he counts as a scientist.
Fact of the matter is, that energy output comes from somewhere. You can not retrieve more energy out than you put into the system. This fundamentally derives from the homogeneity of time–that the laws of physics were the same yesterday as they are today.
So, I urge you to consider more carefully how you word articles in the future. This *is* interesting. I’ve never seen parametric resonance applied to pumping water, and it will certainly make me think about things in a different manner. It is not, however, a free energy source that produces 12 times as much energy out as you put in. There also is not “little argument that Milkovic’s design represents an important scientific breakthrough with yet-to-be understood implications for a world with constantly-growing energy needs.”
It is clever engineering and misunderstood physics. It is not free energy.
For what it’s worth, my degree in physics comes from the California Institute of Technology, Pasadena, CA.
Michael-
Thanks for your comments. I was as incredulous as you are about this whole thing - especially with the claims of a twelve-fold amplification.
There is another paper which I didn’t link to in the post that measured an amplification of roughly 2.3 times( http://www.veljkomilkovic.com/Images/Jovan_Bebic_Precise_input-output_energy_measurement.pdf ).
I implore anyone who has links to any peer-reviewed, published work that either supports or refutes these claims, to please leave them here.
As Cambridge University are celebrating 800 Years 1209 to 2009, I am sure D.A.M.T.P. will be evaluating these claims with the customary impartiality. It always helps to ‘think out of the box’, What? one might ask, would be the heaviest pendulum that a normal person could oscillate? I guess ten tonnes is perfectly possible. A wrecker ball is from 4.5 to 6.0 tonnes. Perhaps later this year we can arrange for a public demonstration of a 5 tonne wrecker ball, oscillating in a Non-Linear Dynamic arrangement, as exemplified by Veljko Milkovic’s aparatus? or even more simple experiment; just insert a shock-absorber and suspension spring, encased in a suitable calorimeter, into the wrecker ball cable, then measure the heat generated, over a given time span of oscillations. The input energy can be measured with a small electro-magnet/string attachment and falling weight over a pulley, in honour of James Prescott Joule, who’s paper was rejected by the Royal Society, but fortunately accepted at good old Cambridge University. BRAVO! 800 Years! (Also 300 Years for The Saint Paul’s Institute…maybe make those pendulums, into large bells?)
“Force != energy” sums it up pretty well. There are multiple forces at work here too, the hand pushing the pendulum is NOT the only force being exerted. Gravity is present, and I’m sure friction has been greatly reduced in the mechanism of the pump itself.
It’s a great way to do minimal work and get max output (like using pulley systems!). However, this isn’t giving us access to “free” energy, and as soon as someone states it is, they are discredited scientifically (as they usually should be).
I’m all for exploring this further. Let’s not forget that the greatest scientific breakthroughs all met widespread resistance from the scientific community at large. A discovery isn’t about obeying laws, it’s about breaking them!
