A grey morning

On the roof of unit 4 (the elevator of unit 3 is broken) so I had to choose the next unit because I don't walking the stairs up 55 mtrs to the roof....)
In front you see the damper of the safetyvalve of the medium pressure steamdrum, on the left the funnel of unit three, and a ventilation hole in the roof of that unit. ( a roof on top of that hole to prevent rain from falling in).
In the back is the funnel (chimney) of EC 20 and peeping through the falling rain a windturbine).
The grey thing on the far right is the elevator housing and staircase of unit three.
