Maybe we can finally invest in more rail?
This is a suspiciously nice side effect.
I’m very anti-war, but whenever a wide swath of the airline industry has had to shut down, like in 2008 and 2020, it has historically translated to dramatically lower air pollution numbers.
Was ist just temporary, or long term? Because last I heard air travel is on an all time maximum no?
Drops in pollution are always temporary. The Epstein Class is insulated from the effects of their industrializing.
Side effect of having, basically, a wholly capitalist planet.
Effects are only localized, since the war results in massive air pollution.
And water. There have been a number of oil spills from ship attacks.
Next do not sell any fuel to private jets…and then do cruise ships!
That’s fantastic news.
Maybe it’s about time we started figuring out alternative way to travel. Maybe something that doesn’t require burning fossil fuels.
My first mp3 player (this was around 2002-ish) was power by an AA-batrery. The next year a model came on the market that was powered by an integrated, rechargable battery. I immediately bought that model, realizing it would instantly be worth the investment, because I would never need another AA-battery again.
Somehow the world at large still hasn’t realized what 12 year old me was able to realize all those years ago.
The problem is weight. The energy density of fossil fuels is much higher than lithium batteries.
And here I am in 2026 craving for more AA battery powered devices because internal batteries are harder to replace and I have way too many chargers (USB helped there a bit)
This is the kind of unintelligent pseudo eco the people scare monger about.
Buying new shit cause it’s branded as eco when you don’t need it and could get the benefit without buying it anyway. Just buy rechargeables if you care about money. Or the environment.
Young me quickly then learned that integrated lithium ion batteries were not easily replaceable and degraded significantly after 1.5 years…
So far, oil has been absurdly cheap. Because of that, various industries have been built on the idea of bringing stuff. If oil becomes more expensive, all those industries will suffer, because someone just pulled out one of the cornerstones.
you know there are rechargable AAs right? also energy density, range, whatever look it up
So you are suggesting we power planes with mp3 players? I like that idea, where do I donate for the go-fund-me?
Hold my beer…
Air ships should make a comeback Throw some solar panels on for electricity
kirov airship
because hydrogen is famously inert and helium is abundant?
Or environmentally friendly if leaked. And leaks will happen.
I am somewhat confident that we could get a reliable H air ship, to be fair.
That’s why you put a vacuum in there. It’s made of nothing, so it doesn’t react, and there’s plenty of it in the universe. Besides, it’s also lighter than anything else you could throw in there.
If there is every a tiny hole you go from a small hydrogen leak (dangerous but repairable) to a collapse of the entire airship and instantly falling to the ground
No risk, no reward. You wanna fly the coolest airship or not.
Perfect. Now you only have to find a way to contain that vacuum that doesn’t involve thick, heavy walls and we’re good to go!
Fantastium fibers should do it.
You can also use unobtanium plates with adamantium rivets if you want to make it look cooler.
Jet fuel isn’t exactly inert either and we now have another 90 years of advances in technology since the Hindenburg.
Hydrogen is a 100 times harder to contain than jet fuel.
How to you get to that number?
Obviously the number is meant to be taken 99.99…% literally, which is the same as 100% by the way. And is not just another way of writing much much harder. That would be lame!
But to be fair, I rounded the 100 up from 99.7, which I found by adding 99 and 0.7.
So as you can see the math is solid.But the problem with Hydrogen is not just that it is a gas, which is already inherently more difficult than liquids.
The real problem is that it is a gas basically consisting of only a proton with an electron. So the smallest possible atom, so small it can permeate any material that exist. The only difference is in how fast. When you then also at the same time want to make the container light weight, because if it’s to heavy it completely defeats the purpose, then you have a recipe for problems.There’s a reason that despite the advantages, there has never been found a practical use for airships. It’s not that we can’t make them, they are just not any good for practical purposes.
Let’s just… uhhh… go back to helium.
