The solar panel works to make electricity when it is in the sun light coming in the doorway window.  Out of the sun light the car stops. If the light falls on only some of the panels the car stops. But if even less than half of each of the seven panels gets light the car motor goes.

 
 

 

 
 

Only part of each panel need have sunlight on it  to work.
But only part of  the other direction does not work.

 
 
After removing red beams and replacing them with yellow there are enough pieces to make the stand for the windmill.
The wind mill can generate electricity.
Or electricity can be made to make the windmill go around.

The windmill goes so long we lost track of the time.
We were too busy making the bridge.
The windmill can be seen and operated through the Red Rover program. 

 
 Bridge building is fun even though there are many many pieces.
