Safe, nonflammable helium!
We might not have enough helium for medical equipment, much less a fleet of airships. https://www.nbcnews.com/health/health-news/helium-shortage-doctors-are-worried-running-element-threaten-mris-rcna52978
Thank you, I was looking for this. Helium has important applications in science and medicine, and we cannot afford to use such large quantities for air travel. I’d much rather see development of modern sail ships, possibly in combination with fuel cells.
Although this is a non-smoking area, sir.
Plus imagine how hilarious it would be with everyone walking around with high pitched voices on the blimp. Straight up Alvin and the Chipmunks shit. That’s how it works, right?
Yes, they definitely fill the cabin with helium too because the entire ship has to be lighter than air.
