Water tower in Letná, A periscope in a former chimney

We have ensured the manufacture and installation of a periscope which is with its height of 20 meters the highest in the world. It is located in a former chimney of a steam machine for water pumping in the water tower in Letná. The system consists of a telescope located in the interior of the chimney and the rotating head with a mirror that is installed on the top of the chimney and the entire tower.

  • The head of the periscope is made of a special ring collector of energy, which enables it to rotate in horizontal level practically to infinity because it is not connected to any cable.
  • The rotation of the head itself is regulated by the observer by using the touch control.
  • For safety reasons the position of sun is saved in the system, and when the direction of the mirror gets closer to it, the rotational movement of the head slows down and the machine tilts the mirror toward the ground.
