> The blades are big but not colossal: by compare, the offshore Vestas V164 10MW turbine has 160m blades (weighting 35t); this is being designed for ~100m. That's the part I really struggle with: I could easily imagine value in taking a new approach to blade transport as radical as this if it allowed on-shore installations to get on par with off-shore rotor sizes. But if the result is the same as what's already established, just achieved in a different way, it feels like a microoptimization hardly worth the engineering.

160m is the rotor diameter not the radius.

  Thanks, missed that detail. So the plane, when it becomes available, would be almost long enough for blades deployed off-shore today. (e.g. Siemens-Gamesa SG 14, 108m and 115m)

  Wow, thanks for posting. That really shades what they're going for differently, much more ambitious than I'd first thought. So this will be bigger than 10MW that Vesta. Blades will almost certainly have to be >35t.

The benefit is in opening up new sites that were previously not viable at all.

Work with me, here: dedicated seaplanes for megasized offshore windmills. This would put TailSpin one step closer to being real. Clearly a civilizational win.
