  Why not? Can you explain?

    Even today's airline industry is unsustainable and can only continue to function because it's heavily subsidised. Fossil fuel for airplanes is tax-free and cheaper than petrol, e.g. $3.31/gal w/o taxes in California [0] vs. $2.06/gal (average) for jet fuel [1]. Using atmospheric carbon to generate fuel is significantly more expensive than that as even just capturing the CO² costs more than the crude oil used for jet fuel [2]. The claim of "carbon neutral fuel" basically rests on super optimistic assumptions already. The cost can only be competitive if a world-wide carbon tax on the order of $200/metric ton is implemented, which is very unrealistic.

  Cheaper than Concorde is still very expensive I assume.

  Why can't you have both?

    Fuels made from carbon filtered from the air are expensive. Like... not a bit more expensive, but really expensive. While there's some uncertainty about how expensive - this is technology that doesn't exist today - it's gonna require massive amounts of energy, which is simple physics.
    • pfdietz 5y ago
      It doesn't really make sense to make fuels from CO2 drawn from the atmosphere if we're still pumping oil. Instead, make jet fuel from the oil, then make that carbon neutral by capturing and sequestering the CO2. This will change if green hydrogen becomes very cheap, but not yet.

  One way this could work is if we massively scale up renewables. While from a climate perspective you'd want energy to be as expensive as possible as long as there's fossil in the mix, from a social perspective you'd want it to be as cheap as possible. Ideally, all neccessities (power, food, water, transportation) could be made so cheap that everybody can afford them, and they cease to be commodities. If you produce so much power - think solar on every rooftop, maybe one day fusion or clean fission becomes available - you will neccessarily have some way to store surplus energy. Especially with solar and wind. I can imagine that one way to do that will be synthetic fuel from air or from trash. So yes, today it is not feasible (with today's technology and society). But I think it is not more unrealistic than other ideas popular around here, like hyperloop, fusion, or self-driving cars.

  I assume Boom will be owning the global IP on the carbon neutral fuel. because otherwise all other planes will equally carbon neutral.
  • ClumsyPilot 5y ago
    "I assume Boom will be owning the global IP on the carbon neutral fuel" How would they come to posses it? I don't think it's patentable given the breadth of the topic and amount of research already published.
    • hef19898 5y ago
      Exactly, which means the carbon neutrality claim is just PR...
• azernik 5y ago
  Cheaper than Concord is not cheap in absolute terms.
