WIND POWER.
One good use to which the wind force obtained from a fan motor can be put is shown in Figs. 1 and 2. In Fig. 1 is a section of a water tank, which tank should sit in the show window, filled with water.
A toy ship is on the water and is guided in a track, A, which track is attached to bottom of tank. Guide wires, B, B, extend from the ship to grooves in the track. Fans, C, C, are set up at each end and are covered with window trimmings in front so that they are not in view. The fans are run by means of cords from the motor. The arrangement of the fans is as shown in the top view of the tank in Fig. 2. The fan at the left is at D, and the wind it produces sends the ship across the tank at opposite side, on line with the arrow. The grooved track holds the guide wires B, B, of the ship, and steers the ship around G, and the momentum carries the ship to H, where the blast of air from the fan at E sends the ship along course I to J, and thence opposite D again, where the course is commenced over again.
