A solar balloon is a balloon that gains buoyancy when the air inside is heated by solar radiation, usually with the help of black or dark balloon material. The heated air inside the solar balloon expands and has lower density than the surrounding air. As such, a solar balloon is similar to a hot air balloon. Usage of solar balloons is ...
August 6th saw the maiden public flight of the world's first hybrid hot air balloon, which flies by heating regular air from the sun alone. (Google's Project Loon balloons are also solar-heated ...

Balloon designs for possible planetary missions have involved a few unusual concepts. One is the solar, or infrared (IR) Montgolfiere. This is a hot-air balloon where the envelope is made from a material that traps heat from sunlight, or from heat radiated from a planetary surface. Black is the best color for absorbing heat, but other factors ...
A solar balloon is a black balloon that is filled with ordinary air. As sunlight shines on the balloon, the air inside is heated and expands, causing an upward buoyancy force, much like an artificially heated hot air balloon. Some solar balloons are large enough for human flight, but usage is generally limited to the toy market as the surface ...
The lower density of interior hot air compared to cool ambient air causes an upward force on the envelope. This is very similar to a hot air balloon, with the notable exception that an airship has a powered means of propulsion, whilst a hot air balloon relies on winds for navigation. [1]

Ultramagic special shape balloon, managed by Paseosenglobo and sponsored by Movistar Ultramagic N-180 with special shapes, registered in the Netherlands. The company has its roots in 1978 when three friends, Josep Maria Lladó, aeronautical engineer and balloonist, Joan Comellas and Jaume Llansana, [3] started to fly with a second-hand hot air balloon, and soon after decided to build a bigger ...
