Small-footprint high-tech wind turbine, to scale.
I didn't invent this; it's a real thing. And they're apparently monitoring for bird strikes, and none have ever happened. Apparently, when the rotor really gets spinning, it looks pretty solid to birds.

The rotor is 5 meters tall. The mast can vary; this one is 9 meters. The model is to-scale.

I like the model a lot, innovation and design is very important - I have just 1 criticism of the design - perhaps you should add a chicken wire cage around the rotating part, because apparently a large number of birds die every year from wind farms after gliding and become trapped in a slipstream. Also the standard distance to look for dead birds was only 20m for the windmills, they can send bird corpses a lot further in reality.
