    Transmission of energy requires… energy. Furthermore tiny antennas mean a high frequency, which don’t transmit a long way. Not sure we’re breaking the laws of physics any time soon, even ignoring energy density limits.

      Motors get tiny as shit apparently from what I’m seeing, but the smallest batteries I’m seeing are 0.5 mAh, 3.2 by 2.5 mm.

      I see tiny motors that are 3mm by 8mm, and run at 2.7v. Using that motor and battery we are at .00135 watt hours. Realistically you would need 2 of those to make wings work so we would have to half that before we get to discussing controllers.

      Yeah i don’t know enough about it, I’d have to figure out weights to see if it could theoretically even get off the ground let alone survive a ceiling fan being on
