  • Would the blades of an electric fan “rotate” in a vacuum environment?

    Just a point of clarification. It’s been answered before that in a vacuum environment (like outer space) a fan will not work. When you say “not work” does this mean that the blades will still turn but no air flow will result or is it totally not going to function at all despite having full electrical power to do so?

    they will still turn, the power is there. the air isnt required for the blades to turn.

  1. rod hehehehe i think you need to buy me ice cream whoaaaaaahh,,,,,,,,,!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    what i understand is that an electric fan is driven mainly by the motor…which is powered by electricity,,i dont think that absence of air will have effect on the motors function.because when u have an electric fan in a normal environment but not powered on it will not turn.provided their is air.

    although it was made to drive air by the use of the blades,,its not air that is mainly keeping it rotating. that is the reason i strongly agree that it would still rotate even with the absence of air

    The blades will still run. But it would be useless because the blade will have no air to make a air flow.

  3. The blades will still rotate. The idea that “the fan doesn’t work” comes from the fact that there is no air for the fan to push forward.

  4. The fan in this case is an electric one, so assuming that there is an outlet in this vacuumed environment, it will spin. If it’s like a free-spinning fan then it wont move, because there’s no air
