Lego Whirligig

After some attempts to use the panel fairings as a propeller blade or pinwheel, i like this variant best.

Cool creations. Thinking out of a circle :)

Amazing! Seems to work very well! I bet that it could be attached to electric motor and produce a measurable voltage. These panels are a reasonable approximation of turbine blades, although figuring out the optimal angle of attack for the blades is not trivial. The yellow one is also interesting, looks like the front of a turbofan engine.

Some time ago I also experimented with using panels for wind turbine, but a vertical one. It has advantage of working regardless of the wind direction, but it was much less powerful than this one - I had to use magnets for suspension because axles had too much friction.

Three of my favorite things....

1) no cars, cranes or boats!

2) Lots of axles and connectors!

3) Movement without engines!

 

Brilliant!

I wonder how much wind these would produce if used as a motorized fan...

Oh right, now I remember seeing that video :)

Nice, thanks for the demonstration!
