Vertical, STACKable wind turbines. Modular

My latest CAD design. Vertical wind turbine, that can be stacked on top of each other.
IN addition to looking SOOO cool spinning around all day….
Soon, I plan to start generating power with a small DC motor, and eventually Try to chare a RING camera with it. 
LOTS more work to do before that'll be working.
thank you everyone for all the Downloads, Boosts, Likes, and Ratings. You have inspired me.
