Wings, Waiting to Fly

The season is here. The sea is (mostly) free of ice, The forest roads will be opening up soon.  Time for the freight ships to deliver the next batch of wind turbines (in bits) to the harbour. 
These are real giants because they have to be tall enough to reach up above the forest to the clear air above the turbulence of the tree tops. You can see one in place in the forest on an earlier blip.
The jagged edge you see on the trailing edge here reduces drag and makes the wing more efficient. 
This is a recurrent theme of mine because I find the turbines themselves fascinating once they are in place. The fact that they simply bolt together, like a child's model gives them a strange mix of hi- and low-tech. On the ground they form strange and beautiful sculptures, and you can see just how big those blades are!
