There are a lot of Molinos and Molinas around Fuerteventura. They have a different architecuture as the windmills in north europa. There wings have the size of satellite dishes for broadcastind something. So for me they look like a kind of historical satellite dishes. Like they have broadcasted something centurys ago with thouse historical satellite dishes. A signal to the great ships who conquered the new world. But the wings size makes sense because Fuerteventura is full of wind. You have more a problem with to much wind as with to low. A lot of Thouse Molinos and Molinas are very small. I guess many farmers have had there own.
