Sailing Ship

As already mentioned on the side "Zédolille", the inversion of this windmill gives us a new propulsion for ships.

A new sailing ship could look like this:

A 9-Zédolille collects, the other 1-Zédolille gives the energy.

The picture above is self explaining. Instead of a ship's propeller an in the water dipped Zédolille ensure the propulsion. This has not the disadvantage of a ship's propeller, that the water behind gets a whirl, this effect costs energy. The turning moment of the windmill is useable directly for the propulsion.

Even if the ship is not on the optimal route for sailing ships (on the picture above: it runs before the wind), the sails of the Zédolille are running alright.

Dolphins make with their caudal fin an up- and down-movement. The up-movement brings the fin into the right position, the down-movement oblique behind as at an half lemniscate delivers the propulsion. At a ship's propeller there is the problem of the cavitation: the water flows very fast and evaporate. This little blebs implode and this erode the propeller. At the new propulsion this effect is weaker.

There are sailing ships with Flettner rotors. These use the Magnus effect for the propulsion. In the wind huge motor driven cylinders rotate. Instead of a Zédolille on top of the roof you can take a Tirajator, too. This has the advantage, that you must not align the windmill after the direction of the wind. But I do not know the strength of the Magnus effect upon the Tirajator. So it is time to build one and to take the measurements.

instead of a Flettner-cylinder a Tirajator

A ship with the Tirajator would look like on the drawing.
