🏒 Lucian Marin I wonder if it's possible to build a zeppelin made out entirely of aluminum. Or just use aluminum for the main parts: helium chambers and propeller. Carbon fiber could be used for the rest of the aircraft.

☕ David Antoine I guess that would be possible for the structural frame, just like modern aircraft. Carbon fiber would probably be more useful for the helium "tanks" instead of the more comparatively heavy Aluminium. I think SpaceX is testing carbon fiber tanks for their rockets. Maybe the technology will then "top down" to zeppelin-style ships... But when thinking about it, carbon fiber tanks should be more easy to make for non-compressed helium at air temperature, but I'm not sure. It's way more complicated to build tanks for ultra-cold liquid rocket propellants or coolants ... So maybe that should be more easy to do for a Zeppelin...

Adam Douglas Just reminded me of this for some reason: m.youtube.com/watc... poor Madeline
