A Million Green Ideas

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?

Best reply by greengunge:

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