No, although the blades of general industrial exhaust fans are large and absorb more wind energy, their motors are also huge and require a lot of energy to spin. The energy absorbed by the fan blades is equivalent to the amount of energy required. to turn the engine. The energy is really negligible in comparison. This can't turn the motor at all, and naturally it can't achieve the purpose of generating electricity. It's better to upgrade to a smaller motor. /p>
The above is just my guess. I didn't see any industrial exhaust fumes. The poster himself saw the operation based on the actual situation. If you don't know how to do it, you can leave me a message. I am very interested in physics, but I must declare in advance: I am 18 years old and. have completed secondary education. If you trust me, I will ask you. If yous don't do it, I will reject you.
