I just love them so much. Everytime I watch historical footage from the early 20th century I get very sad over the zepplins and blimps. I wish I could see them floating through my sky on a daily basis just doin stuff that isn't solely advertising. They are the closest we have to sky whales. I just love that they float around like that, very joyous and whimsical. Fucked up we don't make use of them anymore. I bet this makes them as sad as it makes me. Relatively low energy cost btw.
I've cried over this while drunk more than once. Think of me next time you call blimps useless technology
Plus materials science has come miles since then. I'm sure you could further lower the fire risk with tougher textiles, modern ultra-light nonsparking alloys and redundant multi-chamber designs. This shit could be made to work.
