ABSTRACT:
A magnetic conveyance system uses magnetic drivers within a tube having pressurized fluid moving therethrough. The magnetic drivers have magnets mounted at an angle other than 90 degrees to the central axis of the tube. Outside of the tube, a cart has a magnet thereon and is moved by magnetic force interaction when the driver is moved by pressure of the fluid, preferably a liquid such as water. A number of balls flow in the tube and keep the magnetic drivers spaced apart. The balls also serve to push the magnetic drivers as the balls are more directly pushed by the pressure of the fluid. A water wheel is connected by gears to an index wheel and serves to keep the balls, and thus the magnetic drivers and associated carts, moving in the proper direction. The carts may be configured as model cars, trucks, and other such vehicles which move on a board having a simulated road surface with the pressurized fluid tube mounted thereunder.
