Defy the wind with this little wind powered car! Take an opposing force and use it's energy to move against it. This tiny car demonstrates that you can harvest the winds energy and transform it into motion directly against that very wind. :)

Harness the power of the wind

- Force Breakdown
1. The wind cups use their large relative surface area and cone shape to harvest the wind as a force acting into the cup, creating clockwise rotation and preventing counterclockwise rotation.
2. The wind cup shafts transfer the force to the top fitting. Their long relative length creates a larger moment and translates to higher torque.
3. The top fitting directly transfers this torque to the first vertical shaft and "small gear".
4. The "small gear" and "large gear" work together reversing the direction of rotation and they gear down which increases torque further.
