sky blades

I didn't know what to call this because I dont know what it is! Does anyone?

I see it everyday on my way to work and it stands high on metal feet outside a farm. I guess it must have been to do with the wind but seems too old to be a wind turbine -possibly just turned something on the ground.

Reasonable day at work . Looks like my job is secure for a while which is just as well as I didn't get an interview for the one I applied for. Not a huge surprise -I picked up they were looking for someone with a different background but i would have been good at it I know!!
