Welcome to the World of Pendulum Power

Veljko Milkovic's Two-Stage Mechanical Oscillator -- A Mechanical Amplifier of Clean Energy
A simple mechanism with new mechanical effects, represents the source of clean mechanical energy. This gravity machine has only two main parts: a massive lever and a pendulum. The interaction of the two-stage lever multiplies input energy into output energy convenient for useful work (mechanical hammer, press, pump, transmission, electric generator...). Read More
