A device for harnessing energy from wind comprising: a central generator including a rotor and at least two blades elongated axially in a vertical position, said blades being oriented radially in a horizontal plane and having an active surface area and further including means for harnessing kinetic energy, said active surface area including cells for engulfing air currents; means for masking said blades when their displacement is in a direction opposite to a direction of said wind; means for supporting said generator; and shock absorber means comprising; a first shaft; rigid cylindrical cover rigidly coupled to set first shaft for transmitting energy to said generator; said cover having a longitudinal groove on an inside surface thereof; second shaft having first and second ends, rotatably disposed at said first end inside said cover and coaxially therewith, said second end being coupled to said generator, said shaft further including at least one helical groove thereon, which groove progresses on turning in the direction of rotation of said cover towards said second end; cylindrical cursor having first and second ends, said cursor being longitudinally slideable in said cover, and having at least one rib, said cursor being coupled to said cover when said cover rotates by said at least one rib which circulates in said longitudinal grooves, said cursor further having a diameter substantially equal to said diameter of said second shaft, said second shaft passing there through and having at least one helical rib in correspondence to said helical groove; and first and second springs located in said cover and coupled between said first and second cursor sides and said first and second ends of said cover respectively.
