I think passenger ships are going to make a comeback at some point in the next 50y. International air travel is one of the few big climate impact vectors with no reasonable substitute. Domestic you have possibility of better all-electric high-speed rail...

Makes no difference. The problem is high altitude carbon emissions which are 4x worse than sea-level. Biofuels are still combustion based.

i'm thinking solar-powered (or at least assisted) hybrid airships are gonna be a thing

Isn’t shipping responsible for much more co2 emissions than air travel? Like 17% vs <2%
Making ships less dirty + simplifying supply chains would prob make much more difference

Not on a per-pound-per-mile basis, plus air travel has higher impact emissions because stratosphere altitude emissions cause about 4x more impact for same amount of CO2.

And travel by ship-not a cruise which goes in a circle but rather a journey from one place to another - is contemplative and soothing. The exact opposite of air travel.

Lots of development going into battery electric aircraft. The trends in battery cost and energy density point to short haul flights being CO2 neutral in maybe 20 years? Hard to say if intercontinental flights will ever get there though

Feels like there should be a status aspect to this game. Time taken could be a feature. Signalling you're time rich. Would make lowering cost a non-issue to start.
