Hot air balloons are only used for recreation. They are not an efficient means of travel, just to have fun.
Yes, mostly just for pleasure. But they have been used to explore the rain forest canopy from above, for various forms of research in the air, and there are even plans to use them on Mars for exploration, where of course they would not be heating air as we know it but the 'air' that is on the surface of Mars.

Are still used today for studying climates and the layers of the atmosphere?
Hot air balloons
Why is hydrogen used to inflate hot air balloons?
Hydrogen is not used to inflate hot air balloons. Just regular air is used which is then heated to make the balloon more buoyant as hot air weighs less than cold air. Hence the name hot air balloons.
What source is used to fly hot air balloons?
Wind !... The balloons are filled with hot air, which causes them to rise. They are then at the mercy f the wind direction.
Is a hot air balloon filled with helium?
No, hot air balloons are typically filled with hot air to become buoyant and rise. Helium is an alternative gas used in some balloons, like party balloons or weather balloons, due to its lighter weight than air.
How were hot air balloons used when first invented?
When hot air balloons were first invented, they were mainly used for recreational purposes and entertainment. They were also used for scientific experiments, such as studying the atmosphere and meteorology. Additionally, military forces used hot air balloons for reconnaissance during wars.

What are hot air balloons used for now a days?
Hot air balloons are now mostly used for leisure
Why is the hot air balloon needed?
Today hot air balloons are only for amusement.
Is helium used in hot air balloons?
No, it is not. "Regular" air is used, and it is heated. Hot air is less dense than cooler air, and it will rise. If hot air is trapped in an envelope, it will give lift to the envelope and an attached payload.
How were hot air balloons used by the military?
The first use of hot air balloons was in the American Civil War for surveillance of troop movements.
Which gas do you use for hot air balloons?
Hot air balloons typically use propane gas as a fuel source for the burner that heats the air inside the balloon envelope. The propane is burned to heat the air, which causes the balloon to rise.
Does a hot air balloon have helium inside it?
Hot air balloons do not use helium; they are typically filled with hot air. Helium is non-flammable and more commonly used in other types of balloons like weather balloons or party balloons. The hot air inside a hot air balloon is what allows it to rise and float.
Why is hydrogen used to inflate hot air balloons?
Hydrogen is not used to inflate hot air balloons. Just regular air is used which is then heated to make the balloon more buoyant as hot air weighs less than cold air. Hence the name hot air balloons.
How were hot air balloons used during World War 1?
Hot air balloons were used to spy on the enemy. They were also used to communicate, send supplies, and drop bombs.
