Pennies in Motion Motor
grabcad
A toy vehicle incorporates kinetic energy from forward movement into a spinning wheel mechanism. By inserting coins inside this wheel, it may retain some of this energy for release when placed on the ground. Repeatedly pushing the car and lifting it in the air should cause it to move a few inches autonomously upon being set back down. The truck's top is detachable, with plans to reveal dimensions for custom designs. At present, only renderings are shared as the gearing specifications and configuration are still under development.
