To solve the problem in that, in a conventional hot air balloon, air inside the bag of an air balloon is warmed by thermal power such as a gas burner to obtain static buoyancy, which results in problems such as the weight of a thermal power device and temporal restriction of a heat source.SOLUTION: A buoyancy source for a bag for a hot air balloon or for a thermal buoyancy device is made of a lightweight material such as resin or ceramics, and heat resistant process is performed on the inside thereof, and a heating wire is arranged. Problems such as the weight of a thermal power device and temporal restriction of a heat source are solved by warming air in the buoyancy source by electric power rather than thermal power.SELECTED DRAWING: None
【課題】従来の熱気球は、ガスバーナー等の火力で気球の袋の内側の空気を暖めて静浮力を得ていた。この方法では火力装置の重量や熱源の時間的制約等の問題があった。【解決手段】熱気球の袋又は熱浮力装置の浮力源を樹脂やセラミックス等の軽量な素材で作り、内側に耐熱加工を施し、電熱線を配置する。火力ではなく電力で浮力源の空気を暖めることにより、火力装置の重量、熱源の時間的制約等の問題を解決する。【選択図】なし
