Ha, yes let’s use a limited resource (helium) to save the earth!
No, I don’t have a better idea… and maybe the improvement is worth it. After all I’ll be dead in 100-200 years when helium runs out on Earth, but climate change is already having a huge impact.
I concur. This is really fucking stupid. The only actual advantage that airships have is loitering time, and solar aeroplanes can already loiter for months albeit with a small payload.
If you really care about the environment, make it an unmanned post and use more efficient (because it's lighter) and abundant hydrogen. Chance of explosion is pretty low, and if it does who cares.
Afaik they want to use hydrogen, it is actually pretty safe with modern understanding, but regulations make it hard to pursue.
I think people that dismiss hydrogen airships as impossible to make safe because of the Hindenburg miss that planes of that era weren't super safe either, but have been made quite safe today, and that planes are filled with large amounts of flammable fuel. I personally think we should give them another shot.
