The Rainbow, a creation by artist and professor Michael Jones McKean, literally bathes The Bemis Center for Contemporary Arts, in Omaha, Nebraska in a shower of natural color.
In an exhibit entitled The Rainbow: Certain Principles of Light and Shapes Between Forms Project. The human made rainbow illuminates the Bemis Center twice per day for 20 minutes, using rainwater harvested using expertise and hardware provided by Lindsay Corporation and Watertronics. McKean’s work emphasizes “….the placeless, celebratory, seductive and elusive qualities of Mother Nature’s spectacular rainbow”.
The rainbow is created using captured stormwater that is filtered and stored in six above-ground, 10,500 gallon (39,750 liter) water tanks. A 60hp (45kW) pump, powered by renewable energy, pressurizes the water in nine nozzles mounted to the 20,000sq.ft. (1,860sq.m) roof. The rainbow itself, dependent upon the angle of the sun and the weather conditions, can be seen from over 1000ft (330m) away, or from very close up.
