Thanks titof,

This is the link you should have posted before. Good technology. The other video is meaningless without this presentation.

I patented something similar a few years ago.

I didn't get the funds or grant to fully develop it.
I have an even  better design also on the drawing board - but again no 'interest' from the ones with the money to develop it.
As a lone inventor you can only go so far - time and money permitting.
Big industry seems only able to look at improving existing known designs.

@mine
I am interested in what you are doing. Briefly looked at your patent. Interesting possibilities however
the number of moving parts may make the device prone to 'things going wrong'

I would like to know more.

I believe that an important part of the sailing principles has been left out here.
Anyone who has experience with sailing understands the principles of sailing against the wind.
This principle is not included here.
One could make the blades shaped like bended sails or wings of an airplane, so more advantage can be derived from it.
In such case the blades drawn at the  6 and 12 o'clock positions of the overview drawing will have additional pull counter-clockwise (so, in the direction of the intended rotation) due to the mechanism of underpressure at one side of such bended blades. An example is attached

This will however require flexible blades, since a flipover of the bended side is required when such blades rotate from e.g. position 4 o'clock to 2 o'clock.
