I am mostly interested in the battery tech....

Yeah, that and the transmission of data or storage sounds outlandish. Maybe those just have a microphone and aren't trying to record/store video.
How could it even recover if the wind blows..

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

ahh fuck I left the microwave door open.. why'd all the bugs just die?

Does your microwave operate with the door open?!

If you tried some "repairs" yourself maybe...

From the creators of "Birds aren't real, they're drones" now comes the sequel: "Birds aren't real 2 Electric Boogaloo: Insects are drones"

The CIA developed dragonfly drones in the 70s IIRC, though they had no active electronics and were heated by a laser to guide them (and possibly to measure acoustic vibrations). It’s not clear whether they found a practical use for them.

From what I've read, they weren't practical to use as keeping the laser on them was very difficult.
That's the public info, of course. Maybe it worked very well.
