We do have the technology for this… right?
Absolutely, but the scale of the balloons is a bit off. Nobody would be walking shoulder to shoulder like this. For a normal-ish 170lb/77kg individual your personal balloon would have to be a little under 6.5 meters across assuming it were filled with helium.
Yes, I did the math.
You did the basic math, with your spherical balloon. What about giant cylinders? Then you could really pack it in.
Sure. You could do a cylinder of three quarters of a meter across which seems like a reasonable footprint for someone to stand in. That’d only have to be, uh, 325.5 meters tall to have the same volume.
I fail to see the problem.
Your asshole “buddy” constantly throwing sharp objects at your balloon causing you to be wet all the time and laughing as you ask your mom if she can mend your massive cylinder for the 13th time this month
Note that you wouldn’t need 77 kg worth of bouyancy from the balloon. The shoes would provide some lift, more if you made them out of some type of foam.
We thank you balloon master!
What if the balloons were long and vertical like the ones in Dune? That could allow them to walk closer to one another.
I addressed that in another comment here. The long and short of it (very long, as it happens) is that the volume you’d need is still the same. So your elongated balloon would have to be well beyond what most people would consider to be ridiculously tall. 325.5 meters tall, in fact, given the 0.75 meter diameter I assumed to start with. I figure most people could probably stand in a 0.75m circle provided they didn’t wave their arms around a bunch.

Windsurfing? 🏄♀️
Fucking horse in the background 💀
No, it’s just a water-walking horse.
A Balloon Supported Water Walking Horse…BSWWH for short. Pronounced bsh!
The two Jesuses in the background don’t have balloons!
They’re on a carriage that’s like pontooned at the bottom, being pulled by the horse and driver who each have their own balloons.
edit oh wait d’you mean the ones in the back right my bad dk about them
Back right?
I see two in the back left and two more in the back middle without balloons. The two in the back right are the carriage passengers.
Forget the balloons. I want that water treadmill unicycle!
millicycle
I’m pretty sure they actually exist
When you have the chance to ride a water horse? Forget it.
I love that the balloons are far too small. Like they didn’t understand the elements and buoyancy well enough to know the balloons have to be much larger. Not like we have negative mass particles.
Obviously they were assuming balloons were filled with supervacuum. We have had 100 years and not invented even that.
Truly we have failed our ancestors.
Super vacuum! That will do it.
Well, I guess they figured it’d take another 100 years to calculate that correctly, so they just winged it for the picture.
I’m pretty sure scientists back then could have told you that these balloons are too small. The person(s) who drew that picture most likely wasn’t a scientist, which is why it looks how it looks.
Maybe they thought we’d have discovered/created new elements by now that could do this.
Half hydrogen! Or the rare molecule, puffy air.
Well, if we used a pure vacuum, you’d only get about 17% more efficiency than just using helium I think
Superheated hydrogen in a monomolecular unbreakable balloon.
The theoretical best lift from a balloon that size is about 1 kg I would estimate
C-. You didn’t show your work.
Well, air weighs a little bit more than 1 kilogram per cubic meter, and those balloons look a little bit smaller than a cubic meter
What about hydrogen plasma as hot as the surface of the sun, contained in a weightless force field? The 'balloon is simply a decorative wrapper? Remember, it’s the future year 2025!
Unless there’s force coming from somewhere other than buoyancy, you can’t get better than than 1.29 kg per cubic meter of lift in air at stp.
Curses! Foiled again!
I want to see how that cane works.
I like the fact that a horse and boat thing has the same size balloon as a person.
Not sure how they are walking and not just splashing in place.
And you don’t have an issue with the carriage, with three people on it, where the only balloon is on the horse?
Whoever made this was an artist and sucked at physics
The carriage could be on a barge and is just being pulled by the horse. How is the horse getting traction? And why is that man using a cane on water! The small balloons could just be artistic license for the drawing.
I’d be ok with splashing. I want this!
Edit: Perhaps the shoes have keels or fins at the bottom and they use a skating-like motion to move around.
If we had spent the time working on the real problems, this would have already been solved.
I feel ripped off yet again!
They just thought they’d do everything they did back then, but on water? And with mini blimps?
Fuck being able to buy a house or afford rent, people need mini blimps! (Right, it’s not just me?)
They just thought they’d do everything they did back then, but with balloons. They could already walk on water back then.
“Deutscher Kakao” 🤡
“German cocoa”
ah so german cacao is the red bull of the 1900s, it gives you wings.
Funny that you say that, they actually sold “Scho-Ka-Kola” (Cho-Ca-Cola) from 1935, which was chocolate with coffein.
I do like how it has the sensibilities at the time. Being super dangerous to anyone who uses it.
They were very into helium and balloons
Literally just build a bridge, you hyper-individualistic consumer-centric assholes.
I think the idea here is people want to go out and enjoy the day. Not just walk across a bridge. Next time think before you comment. You sound rarted as fuck
Oh no, the Groypers are here.
rarted? If you’re going to insult someone at least spell check yourself, lmfao.
So, they did predict the water rising.
Now I’m wondering why we don’t attach giant balloons to ships to reduce water resistance by cutting down how much of the ship needs to be underwater. Perhaps it’s because you would need more size for the balloon, and maybe the air resistance and water resistance needs to even out due to physical laws that I’m too lazy to think about?
The boat already floats. What is the point of making it lighter? Boats are handy for transporting extreme weights because water weighs more than air.
If it should fly then get a Zepplin
Any amount of water contact introduces a fair amount of drag. There may be an ideal point somewhere in the middle, but I think if you take this to it’s natural conclusion you get a zeppelin.
I did a little bit of math and I think that to lift the payload capacity (including fuel and crew) of a modern day Panama canal ship you would need about a tenth of the peak U.S. helium reserve (a cube about half a kilometer long on each edge, about 1.3x longer than the long dimension of the ship)
I don’t think you’d get the best fuel efficiency going upwind lol
Anything smaller would come with proportionally less downsides and at least proportionally less benefits. I doubt it could ever be a net positive in any useful metric.
Hydrogen for sure. Partial lift for a boat has a lot of applications. Much more cargo than an airship, with no complications in flying empty. A fairly flat triangular “balloon” can be used as a solar platform, a sail, and be put in neutral wind mode down to the deck.
attach giant balloons to ships
I meam, we did get water skiing and stuff like that.
