“Supergas” by Superflex. In 1997, Superflex installed and tested the first Superflex biogas system. The experiment was carried out at a small farm in central Tanzania, in co-operation with the African organisation SURUDE (Sustainable Rural Development). The plant produces approx. 3 cubic metres of gas per day from the dung from 2-3 cattle. This is enough for a family of 8-10 members for cooking purposes and to run one gas lamp in the evening.

»334 m/s«,2007, is a room installation, which is meant to visualize the speed of sound (c = λ ⋅ ƒ), which is about 334 m/s. Two translucent tubes are filled with propane gas, which is set on fire to cause a chain reaction. A flame is burning from one side to the other, slowly accelerating to the point where it hits the end of the tube. Due to the ratio of the gas-oxygene mix the flame there causes a rapid explosion, which can be heard as a sonic boom. By Carsten Nikolai.
