that's true if you hang a gallon water jug at the end of one rotor.
However, my thought is that if the blades are spinning, the buildup
would be pretty equal on each blade surface. But I believe they shut
down the windmills when potential icing conditions exist. but like I
said, who needs power with it is dark and cold and windy? Once they
are shutdown, they would have to stay that way until conditions melt off
the ice. You sure would NOT want them slinging ice off at whatever the
rotational velocity is.

<<<<< The rotors turn so slow, I am not sure imbalance is a big
problem.>>>
Blades are, say, 90 ft long.... Ice [water] is roughly 8 lb per gallon...
for the sake of simple math, let's put a single 8 lb load 90 ft from
rotational center. Now, do the math for 8 lbs, with a 90 ft moment arm....
How much out of balance load does that represent at 1 RPM.... at 20 RPM...
at the wind shutdown limit speed? [what ever that may be.]...
Could become "interesting" rather quickly because the cord of the blade
[total surface area to collect ice] would factor in the real world
equation
as well...
My... how reality sucks when you live in a perfect fantasy* world...*
