I had been experimenting with the 3D models as well!
here I'm not going to bother manually adding a model to every turbine I've plotted but I was going to see if there was a way to export the turbine kml folders and do some clever search and replace routine to create a kml which would plot a 3D model at the same coordinates.
I have found some really good 3D models in the Sketchup gallery but coudn't really see how to isolate them to do things like alter their size or include them in kml.
As far as the positioning is concerned I got them from a blowup of a rather small gif of the turbine positions and there may well be an error here - either from not knowing the centre of the icon used on that map or a positioning error of the overlay on GE.
If yours are more accurate then would you mind if I copied them into my placemark?
Cheers
