I don't 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 spin 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 helps youwas useful and I wish the author success. . .
A. "Hydroelectric power generation technology" refers to the decomposition of water to generate hydrogen and oxygen, which requires the absorption of energy, so A is wrong
< p>B. The form of "hydropower generation technology" is: Light energy → chemical energy → electric energy, so B is falseC If H2 and O2 produced by water decomposition pass in both poles of the fuel; respectively, and the passing pole H2 is the negative electrode of the power supply, so C is false
C p>
D. produce fuel cells. Water is generated during the process. “Hydroelectric power generation technology” can achieve zero emissions during the electricity generation process, so D is correct;
So choose D.
