Cut your hair.
Currently, the normal power of hair dryers is between 1200W and 3000W, the maximum is 3000W. The power of general hair dryers ranges from 750W at 2400 W, or even more. The 400 W wind is very light, it just blows my hair.
A hair dryer is made up of a set of electric heating wires and a small high-speed fan. When energized, the heating wire generates heat, and the wind blown by the fan turns into hot air after passing through the heating wire.
It depends on the type of air conditioner you have.
Small wind power generation
No matter how big the device is, the wind will definitely blow the blades. but it's not worth the loss of energy. A lot of energy is also lost when converting between the two. So it doesn't make much sense, but if scaled correctly it canstill produce electricity, but the power is a little low.
