Wind Projection

I missed this news item when it came out earlier in the summer, but Air America's EcoTalk resurrected the issue of the military opposing new wind turbine projects because of potential radar interference. Even though some projects recently obtained a go-ahead, it still boggles my mind how the military can't resist taking a stupid pill and instead simply wiseup and drop the proposal.

Looking at the issue from the perspective of an engineer, I can say that no way will windmills cause interference that would overcome the abilities of a experienced radar technician to filter out. The turbines operate at a fixed (or at least very slowly varying) frequency which means that a straightforward notch filter should remove unwanted signals. After such filtering, radar should not experience a problem from phantom motion interference at all.

And I don't buy this rationale either:
A bureaucratic delay was created by a provision in a congressional bill that wind energy companies say was drafted to create more hurdles for a high-profile and controversial offshore wind project near Nantucket, Mass.

The law required the Department of Defense to issue a report assessing the impact that development of wind turbines would have on military radar.
No way. This has got BushCo fingerprints all over it and they have followed the first law of projection by blaming the opposition for their own actions.
