What is it

We speak of a new project based on an already patented principle for the conversion of energy from a fluid that may be hydrodynamic or aerodynamic.

This new concept of wind turbine is not comparable to a horizontal or vertical axis turbines:
The decisive feature of the design is that the movement of each blade is characterized by the positions it occupies in completing a full cycle (rotating or oscillating) axis.

Fig 1

We see in detail the movement made by the individual blade of generator:

If we fix a blade arm r on a point on the axis and force it to turn (or swing) with an angular velocity equal to the angular velocity of the cylinder that rotates around its axis, we get the the working range of the blade which takes place exclusively in one area of the space (right or left) (Fig.1 and Fig.2).

The image in following figure shows the location of the blade occupies in his entire lap compared to the wind direction (arrows bottom).

Fig 2

The movement of the blade is characterized by the positions it occupies in performing a full cycle (rotational or oscillatory) in relation to the axis; the view from above (Figure 2) clearly blades the entire path of the blade .

This operation is the principle that underlies the method which will allow us to draw energy from a fluid (for example wind energy, or hydrodynamic energy produced by river or sea currents), or to obtain propulsive power according to the principle of action and reaction by providing, on the contrary, energy to the blade.

The system thus plays the role of an intermediary unit capable of transferring kinetic energy produced by a fluid to the blade or vice versa to transfer the mechanical energy produced by the axis to a fluid; in other words the same task of a propeller or of a wind turbine but with a completely different principle of operation.
The blade always works in the direction of the flow of the fluid, both when the unit is receives energy and also when it provides a propulsive action.
