A British designer reused the fabric from the old Virgin Balloon to create a clothing line. Otherwise, because the nylon used becomes very porous after being exposed to a lot of heat and UV light, it is not very recyclable.

What is all around you but you can not see it?
air well. i was looking for wind but i guess air could work. lol:)
What is the motto of Southampton University Air Squadron?
The motto of Southampton University Air Squadron is 'Fortibus Ardua Cedunt'.
What are load tapes?
reinforced seams along the length of the balloon envelop (hot air balloons)
What was necesary for the hot air ballon to be succesfull?
A hot air balloon needs to carry a means of producing more hot air to keep the envelop inflated and lifting in flight. Otherwise, as the initial hot air cools, so the balloon will descend to the ground.
Does a hot air balloon use the pneumatic system or hydraulic system?
Neither. Pneumatic equipment uses air, under pressure, to convey mechanical energy from one place to the other. Hydraulic equipment uses water for the same reason. A hot-air balloon uses less dense hot air to fill it's balloon. Due to gravity the more dense cold air sinks down and pushes the hot air filled balloon up. The burner uses a mechanical arm with a spring (with a string and handle attached) to control the amount flame.
What is the craft that uses heat to gain altitude?
A Hot Air balloon.
What uses the same principle as a hot air balloon?
A weather balloon filled with hydrogen is also lighter than air, and will rise to great heights.
What is the purpose of the flame that is lit below a hot air balloon?
To increase enthalpy.the burner uses flames to heat the air so the balloon will rise
How does a hot air baloons fly?
By the hot air that is created from a burner under the envelop (baloon).
How does a burner flame cause a balloon to rise and stay aloft?
As the flame burns it heats the air around it making the air less dense than the cooler air above, the warm air particles rise to the top of the balloon and the balloon rises with the air. Essentially a hot air balloon uses a convection current to stay in the air.
What is the direction control of an hot air balloon?
The pilot of a hot air balloon uses the burners to move in different directions. Some of the air is moving east, while some of the air is moving west. The pilot of the balloon will either deflate or inflate the balloon to catch the wind in a particular direction.
What type of gas is used in a hot air balloon?
A hot air balloon is normally powered with propane. Other than that, it is just ordinary air used inside the balloon.
Can you develop a balloon that produces the same result as a hot air balloon but uses cold air?
yes but it is a long and difficult process. I could use a lot of fancy terms but bottom line is you have to cool the air around the balloon but it is energy wasting
Why can't a hot air balloon go to any of the other layers of the atmosphere?
because the air inside the balloon is heavier than the air outside in the other layers of the atmosphere
