What's the power conversion system exactly? Claims electric and flywheel, but what is it?

The windage of the redirection plates plates is nontrivial, but this is somewhat interesting.

An experimental study on the effects of relative rotation direction on the wake interferences among tandem wind turbines - Springer
Interesting result. Basically, if you close pack turbines, make sure you evenly mix clockwise/counterclockwise rotating turbines to exploit wake turbulence effects. Which sorta goes against the common practice of having all turbines in an array of the same type/rotation. I wonder what happens if the wind turbines are not single rotor, but dual rotor counterrotating turbines? Would the counterrotation cancel out the wake turbulence for downstream turbines, negating the effects?

Strange design. May have merit on the small scale when the rotors don't weigh much, but scaling up is a challenge I would think...
