    Silly design. It has long been known. Very little efficacy and very big danger in a strong wind. The author needs to learn the history of technology, so as not to disgrace further.

    There are wind turbines on sails that work at very low winds. By gathering sails, they also work in very strong winds. The number of working hours is much higher. They can also be put on boats. ru-clip.net/video/IX27qvPlHsI/video.html www.scribd.com/doc/263851374/VJETRENJA%C4%8CA-SA-ROTIRAJU%C4%86IM-JEDRIMA novenews.net/en/technology/boats-of-the-future-197
