Solar Balloon

Developed by Cameron Balloons and funded by Bristol 2015 to mark the city’s status as the UK’s first European Green Capital, the black and silver balloon made its maiden journey at the 37th Bristol International Balloon Fiesta.

Built of a light weight polyurethane coated nylon, the black side of the balloon attracts heat from the sun to make the air inside of the balloon envelope much hotter than the ambient temperature - the silver side of the balloon then prevents that heat from escaping. The balloon is fitted with propane burners, just in case the sun disappears mid-flight, which is what makes it a solar-hybrid.

The Tribute Bristol International Balloon Fiesta runs over the weekend and offers entertainment for the entire family featuring colourful hot-air balloon displays, aerial displays, fairground rides, delicious food stalls and bar, balloon tethering, model aircraft displays, experiential activities and a local music stage.
