But it's much easier to truck in a few dozen tons of ballast than to truck in, say, a 400 ft rotor blade. Transport is seriously limiting wind power, not just because larger gets better wind but also because larger would actually get less nimby, not more: rpm scales inversely with size, and rpm is what draws our attention to where we don't want it.
