    i dunno if it will work irl though. ive used things like ideal gas laws, ideal air density, assumed air pressure is uniform for first 200m of atmosphere, assumed dry air and i rounded everything to 3sf so some numbers may be off. in game it will work though :D.

    bronze has a denisty of 8520 kg/m3. if the spheres have a 1m diameter and 0.001 cm thickness they would have a mass of 1.071kg each (weight 10.7 newtons). air at 800C has a density of 0.000334kg/m3. this means the resulting buoancy force of the displaced air will be 97.6 newtons. which is more than enough to lift some wooden frames.

    If you can do the maths and prove that it would be light enough then sure.

    Wait, Atomic, is the hot air balloon's envelope made of bronze?

    its the air inside it that produces the lift. there is cloth around the sphere to stop it losing heat. when the air inside the sphere heats up, it expands, becomes less dense and then rises.

    Atomic, I don't believe that the sphere would conduct the heat to the air around it very well.
