Abstract
The invention relates to a light floating flue consisting of a wall of fiber-reinforced film which rotates about its axis to balance the reduced pressure in the flue with the centrifugal force on the gases in the flue and with the flue wall. The flue floats due to the friction with the rising air, the upward force of the lighter gases, optionally a zeppelin and balloon-like bodies filled with helium or hydrogen. In order to prevent bending moments on the flue, the flue is attached to the base of the tower by means of a tillable bearing.
