W = *A*P*Sin (42)

The formula (42) shows that, if the force acts in the direction of movement, the greatest work per cycle of oscillation will occur when the phase shifts between displacement and force of 90 degrees.

16. CONCLUSIONS• The aim of this report is not describing the conflict between the law of conservation and

transformation of energy. The result of this project can open a new phenomenon, which really exists in the world, which is originally used by all aquatic beings, and also by those which live on the ground. This method can be also successfully used by humanity for producing energy without harming the nature.

• Mechanism of movement of fish’, birds’ and reptiles’ is discovered. Its realizations allows all beings to receive additional energy for their movement.

• Self-oscillations of the type «flutter» exist not only in technology, but also in living nature.• The useful UAI work is an objective pattern.• Mechanism of management of these UAI is shown. The result of this phenomenon is «flutter»,

that becomes very necessary and important for generating electric energy in the way of conversion the kinetic energy of the flow of the fluid medium into useful work.

• Basing on investigations, this very phenomenon can be applied in the following arreas:• - Generator for conversion the kinetic energy of rivers, channels, sea currents, tidal streams,

marine ground-swells into an electrical energy. • - Wind generators on stationary basements (water front, masts, lighthouses, dams and barriers)

and decks of ocean vessels.• - Propulsions unit on floating crafts (instead of propelling screws): ocean vessels, yachts, boats,

submarines.
