This topic deals with the leading-out or brining-in of the gravitational energy that surrounds us.

The first discussion of this concept on record as far as I know is by Mr. Lee Cheung Kin in December 2004 when he stared at his pendulum swinging toy. Mr. Lee is a Russian Trained Chinese Missile Expert. He is retired now but still acts as a consultant to the Chinese Military.

Mr. Lawrence Tseung did the mathematics and concluded that two parts of horizontal energy can lead-out one part of vertical or gravitational energy.

**So long as there is tension in the string, gravitational energy can be lead-out.** The swinging pendulum toy from the market is a readily available prototype. To convert it to an energy extraction device, the amplitude of the swing should be large and operating at the “hitting the rim” positions. This can be confirmed by the Milkovic two stage pendulum video 6 seen on youtube:

http://www.youtube.com/watch?v=gC6Qlj1Mbo8We shall go into the mathematics in its glorious detail in the following posts. In this introduction, I shall only say the following:

1. In Physics, a horizontal force cannot do vertical work as the displacement is at right angles to the force.

2. In order to do vertical work by a horizontal force, some kind of simple machine such as a pulley needs to be used. The simple machine converts the horizontal force to a vertical force.

3. In the particular case of a simple pendulum, a horizontal force can push the pendulum to a new position. This new position will have both a horizontal displacement and a vertical displacement.

4.

**What kind of force is responsible for the vertical displacement?**5. The answer from the parallelogram of forces is that the tension of the string is responsible for the vertical displacement. The tension can be resolved into a horizontal and a vertical component.

6. When we ask the additional question of energy – the horizontal energy is equal to the applied horizontal force x the horizontal displacement. There is no dispute here.

7. How about the vertical energy? One plausible explanation without violating any Laws of Physics is – the vertical energy is equal to the vertical component of the tension x the vertical displacement. This vertical component of the tension is NOT supplied by the horizontal force. There is no obvious simple machine conversion here.

8. One unconventional thinking is – gravitational energy is actually lead-out or brought-in. We can then do the mathematics with this view or explanation in mind.

9. The resulting mathematical result is that two parts of gravitational energy can lead-out one part of gravitational energy!

10. In other words, when we supply 2 parts of horizontal energy, a total of 3 parts of energy goes into the pendulum system. If there were no loss, 3 parts of energy will be available to do work. This represents a COP (coefficient of performance) = Output Energy/Input Energy of 1.5.

11. Thus the pulse-pushed or pulled pendulum is theoretically an overunity machine. Most scientists overlooked this important concept. The two stage Milkovic pendulum shown on Youtube is NOT a fake. It is solid science.

Since this concept and the mathematical proof are important to all the researchers in the alternative energy field, more posts and explanations will follow.
