A coking plant and a steelworks in Duisburg on the Rhine exhaust a lot of fumes and steam. If you take a longer walk to the banks of the river you can watch this spectacular vista.

There still is heavy industry in the Ruhr Area and part of that ist this coking plant that supplies the nearby blast furnances. This photograph was taken from the other side of the river Rhine in oder to picture the whole very large plant and the beautiful reflections of the lights at the blue hour.
