Rimworld is a tile-based videogame. One of its constructibles in the wind generator:
The wind generator itself occupies a space of 7x2 and can be placed facing the 4 cardinal directions.
In order for it to work optimally, it is required that it has free (unoccupied) space for 10 tiles in front of it and 6 tiles to its back, for its entire 7 tile width, as shown in the image.
What is the optimal placement for wind generators, ie most generators per area?
For an answer I expect a description or even better an image which explains the setup, and a percentage of tiles used by the generators. In order to calculate this percentage, we have to be able to isolate a (hopefully rectangular!) area which can be validly replicated when tiled in the map. I will make a first (obvious and probably suboptimal) answer to showcase this.
