Nowadays an overwhelming majority of usable wind-powered engines is resembling windmills of old times. These constructions inexplicably annoyed some of these ancient times’ contemporaries – Servantes’ Don Chicot for instance – though they were located far enough from centers of population.
A conventional propeller-type wind turbine does not for nothing seem to be dangerous. They really are dangerous - for humans as well as for birds and bats. No wonder they are installed only in the open field, at a distance of 10 diameters from any other object.
As a result, a huge amount of non-used energy roams the planet in the form of wind, but we see only the relatively rare "wind farms" that use only tiny fractions of energy available to us at any time.
Let us introduce you to the future of wind power.
