Balloons and watercycles wouldn't?
Balloons are surprisingly cheap for a finite gas resource
They were very into helium and balloons
Literally just build a bridge, you hyper-individualistic consumer-centric assholes.
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

You could use spherical balloons with really long, but different length, strings for each person. Of course you'd have to avoid tangling your balloons together while walking around like that and given wind can vary with elevation....
You could use hydrogen, which is less dense than helium. Then if it catches on fire like the Hindenburg you’d already be in the water.
It wouldn't help. The thing that gives you lift is the mass of displaced air. Difference from the (lack of) mass of the lifting gas is minimal.
It would, but less than the density difference, since you’ve removed weight from the balloon thus gravity has less of a pull on the balloon. My wife (a PE in thermodynamics) was the one that verified that comment before I posted it, hence why I didn’t say it would increase lift by the difference in density.
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.

Hot air balloon pilot here: We do, indeed.
This is a "Cloudhopper". It's a hot air balloon with no basket: The pilot straps a propane tank to his back and wears a climbing harness. As you can see, the pilot is, effectively, walking on water with the assistance of the balloon.
Cloudhoppers are about 20,000 to 35,000 cubic feet, 40-50 feet in diameter. They are about 1/3 to 1/2 the size of most of the balloons you might see at a fair or festival.
This is the coolest shit I’ve seen all month. Just when you think the world is running out of interesting ideas, you come across something like this and realize you will never see it all.

There's an episode of Nathan For You where he uses giant balloons to help someone who weighed too much to ride a horse normally. Great show

Fucking horse in the background 💀
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.

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

I'm glad we got ubiquitous smartphones instead of only rich people having flying cars.
Still, I'm promoting way, way more punk in our cyberpunk.
The rich do have flying cars. They just call them private jets. The rich own mansions (huge houses) all over the world, private islands, mega yachts that contain smaller yachts, their own submarines, and now they even have their own rocket ships
Yeah, but the police don't hover over us in Spinners as in Bladerunner. They still have to chopper from helipad to airport and ride off in air traffic, so less in our faces.
Their superfluous greenhouse emissions fit the cyberpunk vibe though.
I feel ripped off yet again!
They just thought they'd do everything they did back then, but on water? And with mini blimps?

There are two people water-walking without balloons behind the two women on the left. Time travelers? Aliens? The JFK assassins? We deserve the truth!
