Please don't. We need to be reducing air travel, not increasing it. Go invent a quiet supersonic train or something.
the transatlantic railway is feeling less and less like a funny absurdist joke by the hour
Let's get started on the Snowpiercer too
What is your plan for intercontinental travel? Increased ship travel, taking a week and burning massive amounts of crude fuel oil? Just cut off the Americas and Australia from Europe, Africa and Asia for non-commercial purposes? The supersonics have mostly been used for trans-atlantic and trans-pacific travel.
Less and more efficient airplanes. Supersonic aircraft will consume more fuel.
Let's get weird with blimps
These kinds of comments only say it’s wrong; they never make a valid contribution to finding a solution.
The guy you're replying to or the nonce suggesting we shelve all transportation technology and only use trains?
The nonce, of course.
Oh good, he has too many upvotes for me to assume but I figured.
It's such a shame, you'd think these communities would be about how advancement is always good due to it unlocking new possibilities. For example, maybe this aircraft will open up doors in hypersonic flight that could be used to make more efficient SSTO model and get us less dependent on fossil fuels for chemical rockets via traditional means. Or allows materials science to make a leap forward that revolutionizes fusion.
To just say "why are we doing this?" Is an absolutely insane perspective for R&D and a fundamental misunderstanding of the way we develop technologies.
I think part of the issue is that the fine granularity of Lemmy (or the other place we don’t speak of) doesn’t lend easily to broader topics but instead seems to pull in “only THIS” or “only THAT” binary thinking. Only bikes or only trains or only trams doesn’t help when you need to cross continents.
sailing and solar power exists, and i'm pretty dang certain we could get an ocean liner to cross the atlantic in less than a week with modern tech. Also probably still less emissions than air travel considering how absurly much fuel that uses.
There is a reason the tall masted rigged ships disappeared for regular travel; most people don't want to take a month to cross the ocean in close quarters. Cruise ships are the closest analog to a long haul jet, and are no better to twice as CO2 producing than the airline travel, and the fuel they burn is the lowest grade fuel oil with the worst additional pollution. If you are moving across the ocean, or even just traveling, most people won't be able to pilot their own sailing yacht and take 15-30 days to do it.
That is not said often enough, thank you !
I'm trying to fight the downvoters, you were on -3 when I saw your comment.
Looks like it worked, thanks ! My turn now ^^
That's called a hyperloop, nobody liked the idea.
I think the next innovation will be slow electric powered lighter than air travel. Airships may be the future.
That and these new supersonic planes, they're already happening. Boom supersonic is currently testing their demonstration plane based on this nasa project.

Oh bug off! We need faster travel for a long time now!
Being self centered like this is why we're screwing up our planet.
The planet is fine.
We're in the middle of the 5th mass extinction, it's caused by humans. Climate change is just now starting to actually take effect, and we're locked into many decades of increased disasters and loss of habitable land as the population careens into absolutely record numbers. I could keep going.
The planet is fine though. It's not the first extinsion, it's not the last. All previous ones were caused by some type of living creature as well.
the planet is fine, sure, but do you want to live on the surface of venus? i would personally find that somewhat lethal and prefer being able to breathe the air without immediately dying from carbon monoxide poisoning
So that's what you should talk about - you don't care about the planet, you care about yourself. I don't care how would you feel on the surface of the Venus, I want my fast planes!
i agree, we need to invest in more high speed railways
That too!
We need faster travel?
Yes
