It seems that another little problem has cropped up with those pesky offshore Bird mincers, apart from already discovered:
Wind energy is taking an increasing battering, with vulnerability to storm damage, under-performance and increasing social and environmental impacts giving cause for concern.
The latest problem is “Scour”.
It also appears offshore turbine towers are more susceptible to scour than predicted, according to the latest issue (164 MA4) of the ICE’s Maritime Engineering journal.
A team of research engineers from the Technical University of Denmark report that stone armour around the 4.2 m diameter monopile foundations of the vast Horns Rev offshore wind farm in the North Sea was found to have unexpectedly sunk by up to 1.5 m.
Oh dear. This is caused by the vortex caused by the currents flowing around the base of a wind turbine.

Oops. I’ve a sneaky feeling that they might not last their projected 20 year life span.
Bye the way when are the plod going to make up their mind whether to prosecute the Huhnatic for his alleged speeding offense. if I’d been caught I’m sure I would have been prosecuted by now.
