Tom Hanks made it look easier but he had extra thrusters. Ah - you mean REAL hand fans, not battery operated ones. That's a good point. In the future - when we have 200 meter spherical spaces filled with air in microgravity, there will be advanced, foldable yet super-stiff materials. Instead of the $100 bill, one can unroll (or unfold) that. I like that one a lot, but I'm looking for the best thing that provides whatever power it needs - either storing it or harvesting it. | |

With my luck however, I would carry the cylinder for months, then discover it's empty when I need it most. I might also aim it poorly and put myself into a spin instead of propelling myself across the room. | |

Unless the compartment is utterly huge, all you need is a tiny push in the general direction of the nearest wall. Sure, there will be friction against the contained air, but nowhere near enough to pose a significant problem even if the compartment is tens or hundreds of meters across. | |
