The red color is hydrogen, and the hydrogen generator manages it. If water electrolysis is used to produce oxygen, hydrogen will be produced at the same time, because the hydrogen will float to the top and collect at the top. So it is necessary to build an air pump on top of the base to pump the water. hydrogen and send it to the red hydrogen generator to produce electricity (mainly used to dispose of hydrogen, don't expect to use it for electricity).
I don't quite understand what you said about water breaking down. But I know how to use this little motor to generate electricity. I used to drive this kind of four-wheel drive vehicle and did experiments to prove that it could indeed generate electricity. Experimental steps: First, there are two identical small motors. Place the two motors shaft by axis,then attach the tops of the two shafts, i.e. let the other motor turn it, then go from there. the engine to produce electricity. When the two wires connected above are connected to a small bulb, you can see that the small bulb is glowing, but the light is unstable because there is no rectified current. What I'm talking about is okay as an entertainment experience, but it doesn't make much sense if you want to use it to generate electricity. But I hope it will be useful to you and I wish the author success. . .
