Amid talk of sustainable aviation fuel and electric flights, there's another form of air travel currently being mooted as a green alternative to flying: the airship.
Okay but that’s not the real deterrant. It’s the cost you mention. I would like to take a transatlantic cargo ship despite the extra long journey, but the cost blows it.
I don’t think cargo ships do much better on GHG than jets. But an airship would be vastly more eco responsible than ships or jets. Cost is really the issue though and that can be solved. People taking jets could be forced to subsidize those traveling more responsibly.
Today human hibernation is widely thought to be crazy talk but it’s not far off. We will see it in our lifetime. People in hibernation eat less, need less space, and need less customer service.
Human hibernation is actually much further away than you suggest - we’re still struggling with the fundamental biology of inducing torpor safely in humans and the metabolic challanges are enormous, unlike bears who evolved this ability over millions of years.
