Even long before Leonardo da Vinci (1452-1519), there had been attempts to make a gravitational machine, but in terms of imagination and number of the preserved designs Leonardo is certainly unique. At the time of the Renaissance, the construction of the aircraft Leonardo drew seemed impossible, and yet 400 years later planes and helicopters took off, defying the official scientific position that "objects heavier than air cannot fly".
And 500 years later, we can assert that gravitational machines are possible and that Leonardo's work forms the rock-solid basis, precious for future inventors, scientists and constructors.
Almost all the known designs of gravitational machines and magnetic motors can be reduced to the form of a wheel, i.e. rotation as an important factor. According to the official or conservative point of view, all the attempts failed. However, in the last couple of years the experiments have shown that a much higher efficiency can be achieved with the pendulum than with different kinds of wheels... Gradually, we are starting to understand that the pendulum can use the inertial forces, gravitation and magnets far more efficiently than the wheel.
This is the story of the discoveries, which have been hidden from us for a long time, and were dismissed as science-fiction, until nowadays when breakthrough inventions are receiving awards, appraisals and objective criticism, but also dogmatic
"a priori" attacks. The aim of this bilingual (English & Serbian) book is to present as many facts as possible, which will lead us to the light at the end of the tunnel.
