Atmosphere powered cart. ,, Homemade Science with Bruce Yeany

A large syringe type water toy as a basis for storing potential energy was successfully used to drive a small cart across the floor for about 200 feet. By pulling the plunger out on the toy syringe, a vacuum is formed in the empty chamber and atmospheric pressure trying to equalize the pressure inside the tube drives the plunger back in again with a force of approximately 11. 5 pounds or 51 newtons. As the first prototype to test the concept, the cart was made rather large and heavier than needed but still managed to combine drive and coast for the length of our school hallways and gym floor. Minor efforts were tested at changing the mechanical advantage of the drive but still needs to be refined further for improving distance or speed of the cart. The idea for this was based on: Tom Stanton atmosphere powered car
