From unfair wages to racial inequality, Americans have a lot to gripe about. But it’s not all bad—at least we have the luxury of a porcelain throne. Four out of 10 people in the world don’t have access to a toilet. That’s 2.5 billion human beings forced to defecate in the open, making them, including many children, susceptible to deadly diseases.
'Smarties Mill,' a wind wheel in Sehnde, Germany is seen in this long exposure image on April 15. Installed by French artist Patrick Raynaud in September 2011, the wheel is covered with 30 string lights and strobe fixtures. As wind speeds wax and wane, so too does the intensity and color of the lights, which draw power from the turbine. The design was commissioned by Hanover's Expo-Region Climate Protection Programme for the express reason of showing the public how beautiful wind power can be.
