Vertical axis windmill. They could have been specially made for the purpose!
I'm surprised chunko hasn't made one of these http://www.youtube.com/watch?v=GqwMD_WzIFM&sns=em

That is like an earworm tune, quietly spinning round in my head, very likely to happen.
On the farm there are lots of empty barrels sitting around.
