I put up windmills at the RTI LEGO city for March.
This group is helping by building eLab windmill.
These two are building a fly wheel car first.
The gears have to mesh.
It is sort of like a push forward instead of a pull back car.
The energy is saved up in the moving heavy fly wheels.
It can continue to move for a long time.
Here is the place for the windmill.
There is a little car the goes around.
This is much bigger.
Now that the girls have the main part of the windmill build
every one is going to make one part of the sail.
Finished!
Here is where the windmill will be for March.
