Wind Turbine

From the Introduction:

Amidst the trees of the forest rises a gigantic artificial foreign object towards the sky. A wind turbine dwarfing anything around it by far. Built far from any houses as not to disturb the people living there it still disturbs the scenery of the peaceful forest. Built upon a solid block of concrete buried in the ground forming a small artificial hill rises a huge tube of aluminium and carbon fibre far into the sky. At its top, reachable by a ladder inside the casing, sits the cabin with the actual generator and the giant rotors powering it.
