Why not use hydrogen, its cheap and zeppelins can be smaller and fly higher.
We will maybe better in avoiding accidents compared to 1937:
- have better materials
- can use it only for cargo with drones - no human should travel with them!
- should/can use routes to avoid cities, and should/could build some separate safe landing space
etc...
finally:
Hydrogen fires are less destructive to immediate surroundings than gasoline explosions because of the buoyancy of H2, which causes heat of combustion to be released upwards more than circumferentially as the leaked mass ascends in the atmosphere; hydrogen fires are more survivable than fires of gasoline or wood.[22] The hydrogen in the Hindenburg burned out within about 90 seconds

- b0rsuk 7y agoI would also rather use hydrogen. The Hindenburg disaster was spectacular, but not especially deadly! 36 fatalities, 62 survivors. Compare to modern passenger airplanes, where EVERYONE tends to die. If modern dislike for zeppelins is mostly due to Hindenburg, it's irrational.
- pasabagi 7y agoI think there were a series of disasters - of which the Hindenburg was just the last. All the same, I think with modern materials, Hydrogen would be pretty safe.
- mothsonasloth 7y agoIndeed, Iron Maiden wrote a song about the British Airship R101, called "Empire of the clouds"
- ianai 7y agoIt’s at least worth considering whether modern zeppelins could be safe. All options need to be on the table for dealing with climate change.

- squarefoot 7y agoThe Hindenburg accident happened while the ship was about to land; people on the ground were already holding the ropes hanging from its nose. Had the explosion happen at a higher altitude nobody wold have survived. Using hydrogen, especially today, is a disaster waiting to happen, since any idiot with a medium quadcopter drone carrying a small explosive charge could easily outrun and shot down an airship then post the FPV video on social networks.
- brnt 7y agoI think since Hindenburg fabrics has developed tremendously, and collision, perhaps even explosion safe fabrics for zeppelin hulls could be possible.
- n0rbwah 7y agoHope they still get covered with a thick layer of thermite.
- zabzonk 7y agoYou mean "thermite, the well-known incendiary compound"? https://www.wikiwand.com/en/Thermite https://www.wikiwand.com/en/Thermite
- n0rbwah 7y agoThere's a myth that the hindenburg was coated with different layers of metallic paint that triggered a thermite reaction when the hydrogen caught fire.
- gambiting 7y ago>>Using hydrogen, especially today, is a disaster waiting to happen, since any idiot with a medium quadcopter drone carrying a small explosive charge could easily outrun and shot down an airship then post the FPV video on social networks. Literally the exact same thing could happen with a regular plane(just send a drone into a plane as it takes off), and yet somehow it doesn't happen. I guess people aren't psychotic murderers, or at least there isn't enough of them to worry about it.
- brownbat 7y agoAirline crashes have a surprisingly high survivability rate (because the typical crash is not the craft plummeting from 30k feet, but some kind of runway incident). To your overall point though, hydrogen isn't that much worse. In fact, many leading airship disasters involved helium. USS Shenandoah is typical of the most common enemy of airships--strong winds. The captain warned that the updrafts and storms in the Midwest would destroy the ship but was ordered to fly over several cities anyway, just for a promotional tour. The deadliest airship disaster in history is not the Hindenburg, but the lesser known USS Akron, a helium ship that was simply destroyed in bad weather.
- rootusrootus 7y ago> airplanes, where EVERYONE tends to die Overall, about 95% of passengers survive airplane crashes. If you arbitrarily restrict the stats to just the most severe crashes, it's still over 50%.

- paulsutter 7y agoThis is for cargo - hydrogen is fine. They don’t even need a crew on board.
