  • Great connection to old maritime practices. I wonder if by following those routes at altitude could lead to a transatlantic of less than 48 hours? I imagine a big derigible with sails like pectoral fins and a dorsal and tail fin to steer in addition to solar propulsion.

    I agree that supplementing with passenger rail is a must, especially to get from terminal to terminal. What you said makes me think of airport terminals, but they’re countries away instead of a mile away. However, I do wonder about the impact on fauna that high-speed rail would has while cutting across continents, and if the airships are a way to skip that issue entirely.

    As far helium…iirc, helium on Earth is a byproduct of the radioactive decay of certain elements. There definitely would be ecological consequences of helium “mining”, if we were to source from the ground as is typical. Perhaps a breeder reactor could be built to produce in a way more cost effective (not monetarily). Another thought is an interplanetary drone that slurps up atmosphere from the gas giants and tows it back here. Keep the helium collection and corresponding pollution off planet (does this even work in a solar punk world)?
