Spitlight, Light projector at Enter Museum, Solothurn, Switzerland
The Spitlight projects images onto clouds and rock faces with a beam reaching distances of up to six kilometers and creating displays of 1000 meters in length.
Swiss engineer Gianni Andreoli developed the Spitlight between 1954 and 1955, introducing it at the 1956 Winter Olympics in Cortina d'Ampezzo for displaying results and advertisements.
The Guinness Book of Records recognized the Spitlight as the largest projector globally, marking its position in the evolution of projection technology.
The machine operates through a Super Ventarc carbon arc lamp requiring a 120 horsepower generator to supply both alternating current for movement and direct current for illumination.
The projector's light beam generates sufficient heat to ignite cigarettes and requires ammonium chloride to create artificial clouds when natural ones are not present.
