The (biggest) problem that keeps airships from practical use is that they are huge sails. Big sails mean even small amounts of wind can be powerful forces acting on the airship. In the air a big push from the wind might be safely managed, but if you're near anything solid such as the ground, you can get smashed to bits.

To safely operate a suitably efficient (large) airship, we'd need both huge specialized docks with extremely strong mooring structures to keep wind from smashing the airship into whatever is near it, and a system (such as a 3-axis propulsion system on the airship) that is capable of counteracting wind force acting on the airship when it's near the ground or other solid objects and not docked.

Despite the many attractive advantages of airships, there's yet been anything like a good solution to this problem. There are other challenges too (what do you do when you drop off your cargo and the airship wants to shoot up into the air? Vent gas? Rapidly compress your gas?), this is just the biggest.

Just cover the thing in solar, and run it on electric. Add a couple of wind turbines too. I mean, the whole concept is preposterous, so why not just lean into it?

I calculated, than the airship with 100tonns capacity, and wind speed 25m/s require 25tons trust to compensatecthenwind. It is Boeing jet engine, not Electric fan require.

I've seen some YouTube videos converting Boeing jet engines to electric, but you have to smash that like and ring that subscribe bell to be able to see the build
