3,5 meters diameter

Metal, wood, electrical motor.

It is a circular structure 3.5 metres in diameter, comprising 30 propellers, each 1 metre in diameter, which rotate freely thanks to the rotation generated by an electric motor. Each propeller rotates due to the resistance of the element that we cannot see being moved. Air is a fluid which, as it passes through the propellers, causes them to rotate; however, the rotational speed is so slow that the wind perceived by each one barely causes them to turn. All the propellers rotate in the same direction, creating a movement similar to that of a toroid.
