              A simple mechanism (Figure 1.) with new mechanical effects, represents              the source of clean 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...).              *              watch the video presentations for the full insight in this research              - click here               Figure 1. Mechanical hammer with a pendulum

The              best results were achieved with the lever axel and pendulum at the              same height, and the base of the massive lever above the centre of              mass, as shown in Figure 1.
ORIGINS OF ENERGY BASED ON DIFFERENCE IN POTENTIAL
Energy              is created due to the difference in existing devices. Consumers of              energy use the difference in the potential between the plus and the              minus (direct current) and zero and the phase (alternate current).              All heat and thermal motors accomplish useful work due to the higher              temperature and pressure. Mills and power plants use different levels              of water... 
However,              difference in the potential of two-stage oscillator, "unusual              machine" has not been considered so far.
Figure              2. Difference of the potential during oscillation of the physical              pendulum
1 - weightless state in the upper position
2 - culmination of force during the fall in the lower position
Since              there is a difference in potential (Figure 2.) between the weightless              state (1) and culmination of force (2) during oscillation of the pendulum,              the same is true for centrifugal force, which is zero in upper position,              and culminates in the lower position at maximum speed. Physical pendulum              is used as a single-stage oscillator in the system with a lever.
After many years of trials, consultations and public appearances,              it could be said that this occurrence is being researched and investigated              all over the world (author is in possession of evidence). Simplicity              enables construction of houses by owners themselves.
Efficiency of the model can be increased by mass, since the relationship              between the volume of the lever weight and its surface increases the              mass.
  Energy Measuring
It is  important to note that we are not supporting over unity claim for the  oscillator where              its  pendulum was initially raised to some height and then left to swing until it  stops.
Our idea is  that after  initial raising of a pendulum it is necessary to keep adding a  little  energy              to a  pendulum to keep it swinging. Because two stage  oscillator is supposed to be  used for               long period  of the time, energy spent for initial raising  can be disregarded. The same  logic              is for Diesel  engines where it is necessary for them to  achieve working temperature before  measuring its efficiency. Nobody  would also include energy spent for magnetization  of permanent magnets  in an electric motor for calculation of efficiency ratio  of his  electric motor.
It is  necessary to measure  small energy continuously added to maintain pendulum  swinging. Note  also that output force on the lever side is variable and change  from  zero to a maximum defined by its mass. The reason for it is variable  force  of the pendulum which exert pulling the lever on opposite side.  This makes  mathematics complex and precise tools for measuring variable  force are  necessary for calculation of efficiency ratio of a two stage  oscillator.
The well  known fact is  that pendulum with fixed pivot point can keep swinging for  several  hours. Two-stage oscillator has movable pivot point. It moves in rhythm   of the lever which frequency is double higher than frequency of the  pendulum.  The movement of the pivot point, or better to say its  acceleration, keeps  spending energy of the pendulum which decelerates  its swinging fast. Friction  in pendulum pivot point is very small in  comparison with losses due to movement  and acceleration of the pivot  point and can be disregarded. Oscillators with small  and harmonic  movement of the pivot point have better performances and that is  the  reason why special attention should be given to that problem.
Mechanical Fission
Two-stage mechanical  oscillators should be set in accordance  with geometry progression  system, by which mechanical chain reaction could be  achieved:  1<2<4<8< oscillators...
This could be the best way to confirm the overunity effect and accomplish replacement  for nuclear fission.

            POSTULATES AND DOGMAS
              The easiest way is to proclaim something as impossible and refer to              laws. However, are all laws of Physics perfect and eternal?
Luckily, and most probably, they are not. Therefore, exceptions of              extremely efficient machines are possible (Fig. 1-3.).
In the same way, the speed of light can be deemed unreachable, according              to Einstein's formula E=mc2, because the mass would be              infinite. However, the mass does not change with speed, and the kinetic              energy increases with the square speed. Therefore, the speed of light              can be reached by future space crafts, if these ideas are considered.
To  someone it is a problem  if the idea was simple, but coming to the simple  solution is the  hardest and there are the most reasons for that.
