A Solar-Powered Rainbow Machine

Wouldn’t it be great to create your own rainbow in the sky? Well, one clever professor has done this. Michael McKean, of the Virginia CommonWealth University, has invented his own solar-powered rainbow machine. McKean has spent the last 8 years working on his invention, a bona fide rainbow-making machine. Some might wonder why the professor-turned-rainbow-maker would go to all the trouble to produce the colorful phenomena when nature displays them for free — but McKean insists he’s expecting no pot of gold.

Inhabitat offers more detailed report on “The Rainbow Project“:
McKean, a former resident at the Bemis Center and now a professor at Virginia Commonwealth University, has been conducting tests on rainbow creation since 2002. The Bemis Center commissioned McKean to perform this site-specific installation at their facility this summer in hopes of capturing the public’s imagination and engaging the center in wide-ranging conversations with communities throughout Omaha.

The Rainbow Project uses a series of high-powered jet pumps and custom fountain nozzles to spray water into the air, creating the conditions needed for a rainbow to appear. The commercial irrigation equipment is timed in order to create a dense wall of water that mimics a rainstorm, and the sun does the rest of the work.

Beginning next June, McKean is intent on dispensing rainbows to the public, free of charge, twice a day for 15 minutes at a time.
