Green Industry
Shot was taken at fall 2017. I am standing on a Gas-Cylinder called "Gasometer" at Oberhausen in Germany, height 110m, like the one left on this picture. At the upper left corner behind the cylinder you see a great sun clock on a hill, build with two big arcs. What you see is a very small detail of the "Ruhrpott" industry, mainly steel and coal in the past.
