Hot air balloons adjust altitude by heating the helium inside the balloon and letting it cool back down as appropriate. You would need a similar mechanism, but in much smaller format.
- snewk 9y agohot air balloons use hot air (which is less dense than cool air) not helium. they are open by design, unlike dirigibles. hot air balloons increase altitude by adding more hot air via a burner, and decrease altitude by letting the air diffuse out through holes in the top of the balloon.
