A wind turbine automatically feathers. Why can’t the airship automatically raise and lower itself?
With modern forecasting, getting it’s height right shouldn’t be too hard?
Comment on 'Windmill': China tests world’s first megawatt-level airship to capture high winds

With a traditional wind turbine, if the wind speeds get too high, the turbine locks the rotation and feather the blades. For the airship however, people will have to manually take it down and later erect it again. Hopefully they get to it in time, otherwise it’s going to violently take itself down and/or fly off. Either way, that is a bunch of extra cost incurred on a regular basis.

Why can’t the airship automatically raise and lower itself?
Because it doesn’t just need to be lowered. It would need to deflate itself/reinflate itself, while also strapping the deflated bits down or put itself into a massive hangar.
Weather has always been an issue with airships. It’s the main reason you don’t see them in everyday life.

Does the article actually list the target altitude for this version?
I think I was imagining something much higher. You’re probably right.

Article says wind speeds are môre steady up there, wouldn’t that mean whatever you put up there is build to withstand those winds?
