2-Stage Oscillators and the Quest for "Free Energy"

February 9th, 2009 by

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.
