Its magical magical mystery lies in the wire belt, which is a memory alloy. When the temperature exceeds the recovery temperature (35 ° C), the curved part is straightened, as long as it is immersed in hot water. Asymmetric connection with the center of the second wheel, it can automatically turn up, the speed of the small pulley can reach 600 rev/min.
By utilizing the wire material recovery characteristic, a difference in temperature is generated, a torque difference is generated on the driven wheel, and the two-wheel continuous rotation is driven by the frictional force. Thus, the conversion of thermal energy to mechanical energy is simply realized.
During operation, the hot water temperature is 65 °C-85 °C. The memory alloy wire at the bottom of the small metal wheel needs to be immersed in hot water and the driven wheel is inertially activated to start the two wheels.
