A waterspout is an intense columnar vortex that occurs over a body of water, connected to a cumuliform cloud. In the common form, it is a non-supercell tornado over water.
Waterspouts do not suck up water; the water seen in the main funnel cloud is actually water droplets formed by condensation.
To solve the fire protection regulations in the open-plan structure of the Mercedes-Benz Museum, a unique smoke elimination system was developed: an artificially generated tornado.
In the event of a fire, outlets located along the core walls inject air into the interior courtyard of the Museum generating an artificial tornado which collects the smoke and then discharges into the outside air.
