We love anything having to do with air wells, but Marion Rosemarie Wagner and Ivonne Dippmann's project takes the air-to-condensation-to-water game to, um, another level. Project website; Documentation weblog.
Anhelus gathers the water intended for the baptism from the air of the congregation - water condensing on the cool brass point drips into the suspended basin. Since the humidity is increased by the breath of the people (lungs convert oxygen into water and CO2) and likewise by perspiration, all persons present in a sense participate in the act of baptism in which a new member is received into the Christian congregation. Formally speaking, the design is therefore a result of a consistent process of reduction.
