Hot air balloons would work but they would require more frequent fueling and be prone to possibly starting a forest fire. Personally I'd stick to Hydrogen and or Helium as they are much safer than a liquid fuel used for heating air. We don’t need any forest fires.
BTW… The larger the volume of hydrogen used, the less implosive it becomes because it requires a balanced oxygen mix to violently implode. The wider the hydrogen envelope, the longer it takes for oxygen to mix into the gas envelope and it becomes more a meandering floating flame that dissipates rapidly upward rather than the loud popping implosion noted in small hydrogen balloons. In any case, hydrogen or helium would both be safe for such use. The Hindenburg fiasco was not caused by the hydrogen gas as was widely suspected, it was the paint used on the outside of the envelope that caught on fire and burned up in a flash. Most of the oxygen deprived hydrogen pretty much escaped into the atmosphere while some of the more exterior gas gently “burned” upward away from the occupants.
