鉅發企業 ( 香港 ) 有限公司

This car is supplied in kit form and is easy to assemble as step

by step instruction is followed. It is powered by hot and cold water so

it is environmental friendly.

The secret is to use a Peltier device to generte electricity to

power the motor. When one suface of the Peltier device is heated and

the other surface is cooled, electricity is generated. Since higher

torque is needed to drive this car, gears are used to reduce the motor

speed to trade for higher torque.  

Caution:

When handling hot water, it must be done and supervise by an

adult. Also this Kit contains small parts, should be assembled under 

 adult supervision.
