> What he does not mention and what the war in Ukraine has shown again is that dependence on foreign oil is just bad. Make your own carbon neutral synthetic fuel. You're going to need jet fuel at the very least: https://www.abc.net.au/news/2022-07-10/efuel-plant-proposed-for-tasmanias-north-west/101223944 https://www.abc.net.au/news/2022-07-10/efuel-plant-proposed-...

Or we will have to travel less or more slowly using solar zeppelins. Or battery powered plains with in the air charging using microwaved renewable battery. Or we need better batteries the necessary energy densities are hypothetically possible with a theoretical limit of 2,700 Wh/kg of Li-S https://pubs.acs.org/doi/10.1021/acsenergylett.9b02574 https://pubs.acs.org/doi/10.1021/acsenergylett.9b02574 . Chnages to mission profile with Aerotowing for take-off might also help a lot.

  It's not "or", it's "and". You can pootle along in the zeppelin. I'll take the jet.

    The olden zeppelins hardly “pootled” though. They were doing 120kmh at cruise speed. Im sure with modern technology you could up those numbers to 200kmh+. Considering how bad flying is for the environment, I would gladly make the trade to arrive a bit later for a more comfortable, environmentally friendly ride. This coming from someone who flies 20+ times a year.

See how you feel about it when crossing the pacific.

    We will se whether my generation let you take a jet at all.

It’s not synthetic if it’s a biofuel

  Read first, comment second. Works better that way.

    Initially read the article and actually read it again just now - with what angle are you making this comment?

      HIF Global's project is not a biofuel. Maybe try reading it a third time?
