I was looking for an unusual take on the projet water, and found these ducts on the roof of a car park in woking UK. Its part of an environmentally friendly fuels cell that powers the adjacent hotel. I\'s some sort of heat exchanger and everywhere you look you can see a fine mist of water being vented causing the shallow river to run between the pipes. Every time the wind chaged the mist hit the front of the camera and I had to clean the filter!
