  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 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.

    • tyler@programming.dev ⁨3⁩ ⁨weeks⁩ ago

      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.

  What if the balloon was rigid and filled with vacuum?

  source

  • dual_sport_dork@lemmy.world ⁨3⁩ ⁨weeks⁩ ago

    This I am fairly certain we do not have the technology to achieve. Anything vacuum filled that large would need to have walls so thick so as to completely negate any buoyancy effect. I don’t know of any modern material that would simultaneously be rigid, strong, and light enough.

      Cool sci-fi concept tho

      What other sorts of random issues would be solved by this super material

  We thank you balloon master!

  Ok but hear me out

  One really BIG balloon with rope systems you could hook on to so multiple people could walk around under the same balloon area.

  source

  • Hoimo@ani.social ⁨3⁩ ⁨weeks⁩ ago

    If everyone is connected to the same balloon anyway, you could even do without the balloon and build a structure over the water to hang your ropes from.

    Revolutionary. I hear hot air is really good for inflating things. I wonder if you could use some sort of flame thrower to keep the balloon afloat.

      Zeppelin skating. In the air. We should start this business.

      Are we…

      Are we doing this right now, BootyBuccaneer?

        Fuck it I’m in. What could I possibly lose besides a couple limbs and my life savings.

  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.

  Hope that lake doesn’t have any breezes or gusts.
