kinda-sorta. A smallish balloon, like a Chinese Lantern, could probably be made to go airborne by a bunch of hair dryer, hot air guns and similar.
Bigger balloons, it'd be hard to find an electric heat source with enough power.

How much hot air does it take to raise a hot air balloon?
No set answer to that, it depends on how much the balloon has to lift.
What does density have to do with hot air balloons?
The burners on a hot air balloon create hot air, which rises into the balloon and displaces the cooler air from the balloon. Then the hot air, being less dense, will lift the balloon as the cooler surrounding air sinks below it. Once the air cools, the balloon will lose its lift and settle back to the ground. The hot air is only slightly less dense, so it requires a lot of volume to lift the comparatively smaller mass of the balloon and gondola.
Why does a hot air balloon float even though it is so heavy?
Relatively hot air balloon are pretty light, and they have a very large balloon which is filled with hot air, which naturally rises, and if you contain enough of it it is enough to lift the balloon.
What is the difference between a helium balloon and a hot air balloon?
A helium balloon does not need energy to rise in the air. A hot air balloon needs fuel to rise in air. That is it needs heat energy to rise in air.i love Pizza squares i hope they put helium in then one dayHelium relies on the fact that helium is lighter than air. Hot air balloons rely on the fact that hot air has less volume than cold air and is lighter than the air around it. hot air balloons use hot air to cause the balloon to lift as helium balloons use a special gas to cause lift
What gases lift a balloon into the air?
Anything less dense than air (hydrogen, helium, hot air).
Why does a hot air balloon fly?
A hot air balloon flies because it is filled with hot air. Hot air rises and causes the balloon to lift from the ground.
Why does a hot balloon fly?
A hot air balloon flies because it is filled with hot air. Hot air rises and causes the balloon to lift from the ground.
Does a hot air balloon need CO2 to lift?
no, hot air air is used
Why is the size of balloon in the hot air balloon important?
Big enough to allow the hot air to create lift.

Can a hot air balloon lift a car?
yes
Why is a hot air balloon able to lift itself?
because hot air rises
Why does a hot air balloon only go up when it is hot air?
Hot air is less dense then the surrounding air, meaning it's lighter then regular air, allowing it to naturally lift. If something catches that lifting air, and the air is so light that it can lift the required weight up, then it will lift. That's why a hot air balloon requires hot air to lift.
How does a hot air balloon return to Earth's surface?
A hot air balloon comes down when less lift is provided by reducing balloon air temperature to control descent.
A Hot-air balloon consists of a bag called the?
An envelope is the bag in which the hot air is trapped ito to give the balloon lift.
Why does an air balloon float?
If you mean hot air balloon then it floats because hot air rises because it is less dense and with enough hot air caught in the balloon it can lift create enough lift to take off into the air. If you mean a helium balloon then it rises because helium in the balloon is less dense then the air around it. Since less dense things rise to the top the balloon will float.
