So, how did these Dyson engineers create a hot air balloon using a Dyson Hot™ fan heater?
Bristol’s Cameron Balloons advised on and supplied the ultra light weight balloon material, interested to see if Dyson’s engineers could make it work.
It took several prototypes to find the final scale required. And it involved some physics; Dyson engineers needed to overcome the machine’s thermostat control to ensure a continual heated output, whilst working in a chilly space to get the required lift.
It took some time to fill the balloon with the large volume of air required, whilst combating heat loss for the balloon’s large surface area. They used a second Dyson Hot™ fan heater to help overcome heat loss until the balloon took off. All in all it was quite fun.
Warning: This was created and executed by Dyson engineers in a controlled environment. Do not attempt to replicate. Always use Dyson Hot™ fan heater in accordance with its user instructions.
