Recommendations for Construction and Efficiency Measuring

Physics of the Pendulum-Lever Energy System: A Summary of Knowledge
The goal of this work is to summarize the findings from previous papers along with some additional comments and also to answer two basic questions: how to construct an efficient Veljko Milkovic two-stage oscillator and how to measure the quotient of efficiency of the constructed oscillator. The goal of this paper is to explain all the facts about construction and measuring in order to facilitate other people’s efforts towards a replication embodying a high efficiency quotient. »

Energetic Paradox

Mechanical Analogy with Alternating Current
With smaller energetic investment, the pendulum keeps maintaining its motion manifold longer in comparison with above mentioned wheels. Every second the pendulum changes its direction and also moves air. Besides that, steel balls in bearing change direction of its rotation every second. Without a test, the impression would be made that alternating movement would be much less efficient than one way rotation and translational movement. However, just the opposite happens and it can be called Energetic paradox or interaction of gravitation and inertia. »

An Invention Possibly Greater Than the Wheel

Wide usage of the rotation, mainly in the form of a wheel, is deemed to be the best solution, which even new constructions are aspiring to use. However, last years some experiments have achieved greater efficiency with usage of oscillatory devices. »

"Energy Globe Award" for Veljko Milkovic's Pendulum Pump

Hand water pump with a pendulum“ was proclaimed national winner of the world's most prestigious environmental award “Energy Globe Award 2011“ for the Republic of Serbia.

On November 25, in the Austrian city of Wales, i
nternational foundation ENERGY GLOBE traditionally rewarded projects which improve energy efficiency and renewable energy sources and presented the awards to international and national winners in its prestige "Energy Globe Award". International foundation ENERGY GLOBE, based in Austria has been giving the most prestigious international award for environment preservation in the world since 1999. Among other things, ENERGY GLOBE award is intended for all the projects in the world which rationally, carefully and efficiently treat energy sources including renewable energy sources.
This year’s final ceremony was held in the Austrian energy city of Wales, in a beautiful setting of the trade fair and conference center "Messezentrum NEU. Annual award "ENERGY GLOBE" was presented on a gala manifestation under the name “Olympics for our environment” which gathered representatives from over 40 countries, more than 1000 guests, top-ranking laudatory speakers and a huge crowd of press and television representatives.
Almost 1,000 projects from 105 countries was participating for this year's award "Energy Globe" and from those who met the criteria of the international jury, the best project from each country was awarded the national "Energy Globe" award from which the top 15, divided into 5 categories (earth, fire, water, air, youth), were also nominated for global award "Energy Globe World Award 2011".
International jury proclaimed “Hand water pump with a pendulum”, an invention by Serbian academician, researcher and inventor Veljko Milkovic, the national winner in the Republic of Serbia for 2011 for his energy-saving technology for water supply and irrigation. »

Two-Stage and Three-Stage Oscillator as a Compressor

A new scientific paper by Zoran Markovic, Ph.D.: the purpose of this paper is to explain the functioning of two-stage and three-stage mechanical oscillator, i.e. to demonstrate the possibility of generation of excess energy in two-stage mechanical oscillator invented by academician Veljko Milkovic. Compression of air would be proposed for potential application of two-stage and three-stage oscillators. The paper would discuss the dynamics of the body when gravitational forces acts upon it and the methods of obtaining the over unity. »

Oscillations More Efficient Than Rotation

Energetic Superiority of a Pendulum Versus a Wheel in Stationary Machines
The wheel is probably the most important invention of all time. The wheel is in almost every machine and contemporary constructors still rely on all its versions… According to present findings the first pottery wheel was made in Mesopotamia 5,500 years ago. A wheel with spokes was found 4,000 years ago and in the course of time there will be countless numbers of fanciful constructions similar to the wheel or wheels. The flywheel, i.e. massive wheel, is used for stabilization and accumulation of mechanical energy, and belts and gears for transmission...
The wheel appears to be the best solution, widely found in motive devices as turbines in electric power plants. BUT...
The shape of the wheel should not be accepted as the best solution because... 
Oscillations of a pendulum last much longer than a rotating disc. We examine this. »

Tesla's Vision about Gravitational Machine Has Been Accomplished

Nikola Tesla (1856-1943) has published a philosophical paper titled as “The Problem of Increasing Human Energy“ in “The Century“ journal  at year 1900. Many could be surprised by a vision presented by Tesla, in the last paragraph in page 56, which ended in the first half of page 57 in the book: We may even find ways of applying forces such as magnetism or gravity for driving machinery without using any other means. However, almost 100 years after the above paper was published, many surprises were happening and many replicas and analysis were made in the world about gravitational machine with a driving pendulum! »

Analysis of Movement of a System with Elastic Pendulum

Analysis of the influence of pendulum amplitude on movement of a pendulum system during sliding friction and rolling friction - Branislav Serdar, M.Sc. in Mechanical Engineering, has conducted his own research and expertise of Veljko Milkovic's elastic string pendulum experiment. The aim of this paper with accompanying video was to observe differences in the systems under the effect of impact forces on the metal ball of the pendulum, as well as to analyze and compare the results obtained. »

The Secret of Free Energy from the Pendulum

In this work, the author Jovan Marjanovic M.Sc., for the first time has identified the centrifugal force as a source of over unity work under some conditions and also calculated maximal efficiency quotients of the machine. Problems which easy can undermine over unity behavior of machine were identified and solutions were proposed. »
