RE: GERMANY SUBSTITUTES WIND FOR NUCLEAR POWER
... I don't think so ...
Barring special circumstances dictated by terrain and preferential wind
direction, the array can be expected to be hexagonal
(/triagonal/triaxial/etc.) not rectilinear. This augments packing
efficiency, and minimizes unit to unit interference. Use of towers of
staggered height can also be expected, for the same reasons.
This still doesn't overcome the basic point that started this thread - that
THERE JUST ISN'T ENOUGH SHORELINE! :-D
