works by way of a revolving wheel, a spherical shape allows it to rotate with the wheel's power thrust. wheels are now no longer of wood or stone, man has been perfected with a rubber material that is more perfect. so of usage more convenient, safe, durable, and facilitate the replacement. but in the future, there may no longer be used by wheeled transport. because of evolving technology will present a technology that will replace the function of the wheel
