Dan Haas (Noble) indicated in a public meeting, last night that there is no
way a lattice tower could support the new 1.5 mW nacelles!!! A "definitive
engineering constraint". But! Do the tube towers attract coyotes???

My understanding is that lattice towers have been abandoned by utility-scale wind generator developers for a variety of reasons, including the potential attraction of birds to nest on the lattice structure. I doubt that's because of any definitive engineering constraint (i.e., whether a lattice tower can be made capable of supporting the weight of a large nacelle), but it does seem to be fait accompli. Lattice towers still might be employed for small-scale wind generators, though. I'll copy John Dunlop and Larry Flowers, and we'll see what those experts have to say.

Subject: [Delphi] question about wind turbine tower design
I have been reviewing the responses to the Wildlife first survey and the
participants brought up several interesting questions which I will include
in the next round.
Naturally, one of the questions asked was, "Should we prohibit lattice
towers?" But before I add this question to the second round, I want to
verify something I think I heard in the Wind Working Group.
Is it true that lattice towers can NOT support the weight of 1.5 MW or
