## Simplified explanation how to gain free energy from wave fields

When two waves with identical polarization, frequency, phase and amplitude propagate in the same direction and meet (and merge) in free space, then their amplitudes will add together and the amplitude of the resultant wave will be double that of a single input wave.

This physical phenomenon is called superposition or interference of the waves, when (under the above conditions) the amplitude of the resultant wave is calculated by simply adding together the amplitudes of the incoming waves.

The energy content of a wave is directly proportional with the square of its amplitude. This fact has a profound impact on the energy balance of the wave-fields. Calculating the energy balance of the above example, we get that if two units of energy enter the system, then the energy of the output resultant wave will be (calculated as the square of the resultant’s amplitude, that is) four times that of one single input wave (and not only double).

As we see, two units of energy enter the system and four units leave, that means we have gained two times more energy then what we have feed into it. If we take two units of energy from the output and feed it back into the input, then there are still two units remaining for utilization and the process can go on continuously.
