A small blue plastic car with a rear support frame that lifts the rear wheels. There is a solar panel with adjustable unidirectional Angle near the tail of the car, and a fuel cell with two gas and water storage tanks can be installed in the middle of the car. There are two 2mm banana jacks on the panel to connect the motor on the car.
1. Solar power generation
The car motor is connected with the solar panel through the banana plug wire. Under the 60W incandescent desk lamp (or sunlight), the solar panel generates electricity, and the wheel behind the car can turn, and the support frame at the end of the car will be rotated, and the car will begin to move and walk.
2, solar water electrolysis → hydrogen and oxygen power generation
Pull out the small rubber stopper in the middle waist of the two gas storage tanks carried by the fuel cell on the trolley, inject the steam house water (or pure water) into the lower part of the gas storage tank to the water line with a needle, and then plug the small rubber stopper back to the middle waist; Connect fuel cells and solar panels with banana connectors; In the 60W incandescent desk lamp (or sunlight) under direct, after 30 seconds or so can see two gas storage tanks of water slowly rising, and in the lower part of the slowly formed air column, that is, solar water electrolysis into hydrogen, oxygen success.
When the volume of the air column reaches about 8-10ml, the light source can be turned off, and the banana plug wire connected to the solar panel can be transferred to the motor jack of the car, that is, the wheel behind the car can be seen to rotate.
Note: It is absolutely forbidden to use electrolyte in gas storage tanks.
