Enjoy the good life on the Offworld Colonies!

Veritasium made a video recently about the pros and cons of airship feasibility. It's quite interesting.

This is the best summary I could come up with:


As dawn breaks over Silicon Valley, the world is getting its first look at Pathfinder 1, a prototype electric airship that its maker LTA Research hopes will kickstart a new era in climate-friendly air travel, and accelerate the humanitarian work of its funder, Google co-founder Sergey Brin.

The airship — its snow-white steampunk profile visible from the busy 101 highway — has taken drone technology such as fly-by-wire controls, electric motors and lidar sensing, and supersized them to something longer than three Boeing 737s, potentially able to carry tons of cargo over many hundreds of miles.

This morning, the airship floated silently from its WW2-era hangar at NASA’s Moffett Field at walking pace, steered by ropes held by dozens of the company’s engineers, technicians and ground crew.

The first lesson its engineers hope to learn is how Pathfinder 1’s approximately one million cubic feet of helium and weather resistant polymer skin will respond to the warming effect of Californian sunshine.

At the start of September, the FAA issued a special airworthiness certificate for the Pathfinder 1 allowing test flights in and around Moffett Field and the nearby Palo Alto airport, and over the southern part of the San Francisco Bay.

That will involve a long, slow slog to validate the new technologies and to demonstrate, to the FAA and paying customers, that a new generation of super-large airships can match the generally excellent safety and reliability record of today’s commercial jets.

Ha, yes let’s use a limited resource (helium) to save the earth!

No, I don’t have a better idea… and maybe the improvement is worth it. After all I’ll be dead in 100-200 years when helium runs out on Earth, but climate change is already having a huge impact.

[-] Cethin@lemmy.zip 9 points 1 year ago

Hydrogen would make more sense, but people are scared of it. Hydrogen craft are actually pretty safe. I think the British tried to use incendiary rounds to ignite hydrogen craft but there was too little oxygen so they wouldn't burn. They switched to a mix of incendiary and regular round to create holes for airflow before igniting.

[-] Jamil@lemm.ee 4 points 1 year ago

Hydrogen makes more sense, but it's still derived from methane. Not getting away from fossil fuels. And methane is a potent green house gas, far more than carbon dioxide. Any industrial uses for methane will surely have accidental emissions.

[-] Cethin@lemmy.zip 4 points 1 year ago

Well, it's currently generated using methane because it's the most efficient option available. In a world with 100% clean energy with extra capacity available, electrical decomposition of water gets you hydrogen (and a little oxygen to use for something else if you want).

[-] jasory@programming.dev 7 points 1 year ago

I concur. This is really fucking stupid. The only actual advantage that airships have is loitering time, and solar aeroplanes can already loiter for months albeit with a small payload.

If you really care about the environment, make it an unmanned post and use more efficient (because it's lighter) and abundant hydrogen. Chance of explosion is pretty low, and if it does who cares.

[-] DrRatso@lemmy.ml 8 points 1 year ago

Afaik they want to use hydrogen, it is actually pretty safe with modern understanding, but regulations make it hard to pursue.

[-] CarbonIceDragon@pawb.social 10 points 1 year ago

I think people that dismiss hydrogen airships as impossible to make safe because of the Hindenburg miss that planes of that era weren't super safe either, but have been made quite safe today, and that planes are filled with large amounts of flammable fuel. I personally think we should give them another shot.

[-] ekky43@lemmy.dbzer0.com 6 points 1 year ago

Right? I'm embarrassed that we still think hydrogen to be more dangerous than gasoline and other fossil fuels.

I mean, hydrogen is dangerous, as are most things, but it likely won't ever kill 5~10 million people per year from pollution alone.

And regarding airships, hydrogen doesn't just explode as some like to think, and won't just plummet In case of fire if sealed in multiple metallic and flame resistant compartments like in modern airships, at least not without a freak accident.

[-] CarbonIceDragon@pawb.social 4 points 1 year ago

I mean, don't airships also have the advantage of not needing to expend energy for lift, just forward motion? A solar plane doesn't have to worry about this either I suppose, but an airship is much easier to make have useful cargo capacity than a solar plane.

[-] Jamil@lemm.ee 1 points 1 year ago

Neither do naval ships.

I can only see this being useful over land and short distances.

[-] theKalash@feddit.ch 9 points 1 year ago

Lemmy doesn't have a BlimpKink community, yet :(

[-] Viking_Hippie@lemmy.world 2 points 1 year ago

Who can forget the Blimpkink Pork hit "Dumb"? 😉

[-] Lophostemon@aussie.zone 8 points 1 year ago

That’s a lot of helium. WILL NOONE THINK OF TEH CHILDRENSES?!?!?

Think of all those party balloons not sent up into the air to choke turtles out to sea!!!

Think of all the funny squeaky voices not done by daddies to amuse their offspring and they end up passing out from oxygen deprivation!!!!

What a waste to put it in this dumb thing that’s gonna blow up anyway killing loads of peepos.

[-] Viking_Hippie@lemmy.world 9 points 1 year ago* (last edited 1 year ago)

You're thinking of hydrogen. Helium isn't flammable.

I agree that it's a dumb thing, though.

[-] sneezycat@sopuli.xyz 7 points 1 year ago

Helium isn't flammable at all. It's a noble gas, which are notorious for their lack of reactivity.

But I agree, it's a dumb thing.

[-] Jamil@lemm.ee 5 points 1 year ago

Aren't we going through a helium shortage?

Also, to get helium, you get it from natural gas. Seems like a bad choice when you're trying to move away from fossil fuels.

[-] Viking_Hippie@lemmy.world 3 points 1 year ago

Helium isn't flammable at all.

Oops, gonna edit that

noble gas, which are notorious for their lack of reactivity.

Just like human nobles/rich and/or powerful people in general 😉

[-] Lophostemon@aussie.zone 5 points 1 year ago* (last edited 1 year ago)

Helium or Hydrogen it’s all CHEMICALS huh?!? I don’t want anything to do with CHEMICALS. You’ll never find any of that shit in MY body!!!

Besides! What’s the sound that either gas would make rushing out of a hole in the side of that thing?

WHOOOOOOSHSHSHSHSHSHSH

[-] Viking_Hippie@lemmy.world 6 points 1 year ago

Damn right! And physics can fuck right off too! Trying to control what we can and cannot do like it owns the world! 😤

[-] Lophostemon@aussie.zone 3 points 1 year ago

FISIX = 666

[-] eltrain123@lemmy.world 5 points 1 year ago

I can’t tell if your being sarcastic or just a moron…

You do realize that chemicals make up everything you put in your body… right?

[-] dylanTheDeveloper@lemmy.world 3 points 1 year ago

Okay chemical man keep your 5g

[-] Lophostemon@aussie.zone 2 points 1 year ago

“I can’t tell if your being sarcastic or just a moron…”

HEY I RESEMBLE THAT REMARK!!!

[-] Viking_Hippie@lemmy.world 1 points 1 year ago

Don't worry, they were being as sarcastic as a sane young person claiming they're excited for the next presidential election cycle 😉

[-] PatFussy@lemm.ee 7 points 1 year ago

Pretty excited about this project.

[-] Successful_Try543@feddit.de 6 points 1 year ago* (last edited 1 year ago)

Not as large as the Cargolifter, which has only been built as 1:8 model for testing, but still impressing.

[-] ReveredOxygen@sh.itjust.works 10 points 1 year ago

Ok? You can't really call it the largest airship when it was never built.

I propose a new airship design called Cargohauler, it's basically a Cargolifter but scaled up 2x. Your puny Cargolifter is nothing in comparison to my Cargohauler

[-] figaro@lemdro.id 5 points 1 year ago

This just in, I am proposing a new design called the JumboPumper. It is like your puny Cargohauler, but 4x as large!

[-] Successful_Try543@feddit.de 1 points 1 year ago

I just stated that there was a more ambitious project that would have worked, but unfortunately ran out of money. I am impressed that Pathfinder 1 was actually built.

[-] KevonLooney@lemm.ee 5 points 1 year ago

One-upping is aggressive. The better way to say it would be: "there was a more ambitious project that would have worked, but unfortunately ran out of money".

[-] Successful_Try543@feddit.de 1 points 1 year ago

OK. I didn't intend to sound aggressive.

[-] Garbanzo@lemmy.world 4 points 1 year ago

Pathfinder 1 is only built at 1:10 scale though, so it's actually much larger than Cargolifter.

[-] Successful_Try543@feddit.de 2 points 1 year ago

The article states Pathfinder 1 is 124 m long, but does not say that its a 1:10 model. However, Cargolifter CL160 would have been 260 m long.

[-] RememberTheApollo@lemmy.world 5 points 1 year ago

Wonder how such a large and slowly maneuvered craft will fare against the more unpredictable and strong weather associated with climate change.

[-] Quereller@lemmy.one 3 points 1 year ago

The crew capacity seems to be limited for its size. Compared with airships from a century ago. No smoking salon :-) etc. Maybe its the helium instead of hydrogen?.

[-] FlyingSquid@lemmy.world 2 points 1 year ago

The Hindenburg had 50 sleeping cabins.

[-] the_ocs@lemmy.world 1 points 1 year ago

I'd be really excited for a vacuum ship
