comment Is “atmospheric geostationary satellite” feasible with current technology?
@jumpjack - in the stratosphere there is a predictable and stable jetstream - going around the world (in a certain direction) requires almost no energy - staying still would require a lot.

You wouldn't have to compensate for the rotation of the earth - for the same reason you don't on the ground.

comment Time to heat/cool a room
Yes - it's the same exponential curve as a capacitor discharging, or radioactive decay. So of course the room never totally cools. In practice it's trickier because the majority of thermal mass is in the walls, so you would have to model temperature differences within the wall thickness
