Inspired by the last FLL theme, I figured out it would be nice to have wind
turbines as part of the layout... even if they actually might not produce
energy.
At first I thought of having one (micro) motor on each of them, but that
would get a bit too expensive and cumbersome. Then I thought of using some
thread between a motor hidden below and the turbine itself, but that proved
to be tricky and fragile. The final solution includes a 35cm long and 3mm
thick knitting needle that transfers the rotation from the bottom, which
again gives the possibility to run more than one turbine with a single motor.
Some fine tuning is still needed to get them to run smoothly though, but it
is already much better than in the beginning.

Very nice! I built a prototype the same scale that used long rubber bands
through the middle of the 2x2 rounds. After some running in, they ran very
smoothly, and even allowed me to slew the base to simulate slewing of the
nacelle. I haven’t used them in a layout yet though...
