European Tribune

Not quite on the mark a siegel.  When combined with hi-speed downwind turbines, in very specific types of terrain, lattice towers are a problem.  And that's only for small downwind machines.  Lattice towers, properly sited on modern slow rotation turbines are fine.  Especially as virtually all large modern turbines are upwind design.

Here's a shot of the 2.5MW Fuhrländer turbine licensed from one of Germany's top design shops, Wind-to-Energy or W2E.

It's on a 160m lattice tower a bit north of Berlin, world's tallest, installed end of 2006.  Lattice towers are the cheapest way to get up into the stronger winds, though there are trade-offs.  They also can be worthwhile on tough ridgeline terrain.

But is it a good design for a windmill sitting inside a sealed tank?
