For centuries, Serbian inventions have found their way to the world stage, leaving a lasting mark on science and technology. That Serbia still has much to be proud of today is confirmed by Veljko Milković, a scientist and innovator from Vojvodina, whose two-stage mechanical oscillator was recently named one of the top 10 inventions in the world at the prestigious iCAN 2025 competition in Canada.
Speaking for Energy Portal, Milković shared that this recognition brings him both great professional and personal satisfaction, as well as validation for all those who have believed in his work over the past decades.
“These were open-minded people, respected professors who reviewed my work without prejudice, recognized that the invention works, and publicly supported me. This award is, in fact, also theirs — a recognition for all intellectuals and individuals who have wholeheartedly stood by me,” says Milković.
He adds that he does not see his work as a career, but rather as a life mission and responsibility.
“I can’t even associate it with a job. It’s simply my activity, my duty — if I received information about this invention from somewhere. However, I don’t know from where, because that’s a mystery, then I have the obligation to develop it and do good with it as much as I can. Fortunately, the impact is being felt around the world, and this award is yet another confirmation that the effort has meaning,” concludes Milković.

How the Two-Stage Mechanical Oscillator Works
Our interlocutor explains that this invention is essentially a simple mechanical energy amplifier, a mechanism that “profits” from the force of gravity within the natural gravitational field of the biosphere.
According to him, the two-stage mechanical oscillator technology has great potential and room for further improvement, as it is based on principles that open up new research opportunities. He emphasizes that he is encouraged by the growing public interest and recognition of the invention, as well as by the fact that there are still many curious and open-minded people who want to study and understand it.
Milković also highlights that the fundamental value of the oscillator lies in its ability to operate outside the boundaries of classical mechanics, generating new effects that modern science has yet to explain fully. He believes these phenomena should be approached with an open mind and calm observation, since, as he says, “within them lies a new dimension of understanding mechanical processes.”
“The rule with this oscillator,” Milković says, “is that there are no rules. What’s important to note is that ultra-efficiency has been achieved, and the further improvements I’m working on are beyond current comprehension. The system operates on entirely new principles, precisely in the area where no one expected new discoveries — in mechanics, which was believed to have been concluded 300 years ago with Isaac Newton. People used to say that after Newton, there was nothing new to discover in the field of mechanics. Yet, here we are — there is something new. I’m not claiming, even now, that I’ve put a final mark on mechanics — certainly not. But while some scholars have believed that the field was long completed, I simply don’t share that view,” he explains.
The Most Important Practical Applications of the Oscillator
The Serbian inventor explains that the initial application of the two-stage mechanical oscillator was recognized primarily as a water pump, intended for various processes such as irrigation, drainage, purification, and desalination of seawater. Further research revealed that the oscillator has broader industrial applications, especially in piston compressors, where experiments have produced excellent results.
This mechanism can also be used in ore crushing and construction material recycling processes, specifically in crushers and grinders for breaking down worn-out construction waste. In addition, research is advancing toward the use of the oscillator as an electric generator, which could open up the possibility of producing electricity in an innovative and energy-efficient way.
