Using a coil to generate current is nothing new. Using the wind to generate power is nothing new. Using wind to push a magnet through a coil to generate power... Probably has been done in some form. But not like this.
An airfoil slices through the wind to push a perpendicular permanent magent plunger through a coil to generate a current. The aileron/elevon at the trailing edge of this airfoil controls the ascent or descent of the airfoil assembly containing the permanent magnet plunger. When the full depth of descent is reached, the aileron/elevon's pitch is changed via mechanical switching mechanism to provide lift, withdrawing the plunger to it's upper extent. The pitch is adjusted again to begin the descent cycle.
