Best Answer

Zeppelins are kept buoyant by Hydrogen when they were first developed but now Helium as their buoyancy gas, and use propellers to move them to their destination or they just float tethered to the ground.

They differ from Hot Air Balloons in that a Zeppelin has a rigid shape, formed by an internal frame of aluminium, whereas a Hot Air Balloon is flexible and may be folded up.

A Zeppelin is an aerostatic aircraft and stays aloft by filling a large cavity with a lifting gas. Modern Zeppelins use helium which also extinguishes fires in that unlikely event.

Hot air balloons by contrast use hot air which is lighter than the surrounding air but Zeppelins or blimps do not.
