Oxygen Machine

Made from glass, aluminum, and technical parts, 40 x 60 x 40 cm.
Hanover 1983. No. 004.
With all the talk about air pollution, I developed a rough design of the oxygen machine in 1982 at the Documenta 7 in Kassel. I finally built it in 1983 in Hanover. This prototype is an artificial replication of a tree with its functionality as an oxygen producer. Evolution consists of changes. Sooner or later, everything changes.
