Evapotrons are devices used at Burning Man to evaporate grey water quickly and efficiently (and they look pretty damn cool!). A tray is filled with grey water and a drum runs over it which is covered by a dark absorbent material. This drum is constantly driven round by the wind. The absorbed water evaporates from the dark material at a much faster rate than if it were just sitting in the trough.
The website explains this process more thoroughly as well as providing information about the history and development of evapotrons over the years.
Below is an interview of Marco Cochrane, the sculptor who designed Bliss Dance, the 40 feet (12meters) high dancing woman at the Burning Man Festival 2011. People used his I-phone app to control the lighting inside the art piece.

Check the pictures until the last one and an interesting description of the event by the journalist will appear: ” It’s no exaggeration to say the Burning Man festival is one of the world’s hippest and most mind-blowing gatherings. It’s not quite an art festival, not quite a desert rave, and not quite a social experiment, but something of all three. Held each summer in the remote Black Rock Desert of northern Nevada, it’s a week-long celebration of free-form creativity and radical self-expression.
Burning Man takes place in a temporary “city” some five miles wide that rises out of the open desert toward summer’s end only to vanish again after the event is over. For a few brief days, the ephemeral metropolis known as Black Rock City ranks among the largest communities in the state of Nevada.”
