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
I want to see how that cane works.
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!
You could try to use magnetism or something tho, although that means you'd only be able to walk on specially prepared lakes
Don't go down the rabbit hole.
Next we'll be trying to explain why they needed a garbage disposal on the Death Star.
[Two reasons. first, the builder was trying to slow things down so he threw in extraneous stuff. second, there were regulations about ships over a certain tonnage, because no one wants tons of trash falling onto their planet.
I was thinking about this a bit yesterday and I think the most feasible way would be to suspend a glass sheet above the lake, and then give people harnesses with magnets on the top that attach to magnets on the other side of the glass sheet. Then just put ball bearings on both sides to reduce friction.
Actually, the most logical thing is VR. Give folks full exoskeletons to mimic actual real world conditions and a five sense helmet.
Boring to look at from the outside.
What measure of scientic accuracy do you expect from a chocolate wrapper?
I did not know this was on a candy wrapper...
That does make it better.
On the top left it says "Hildebrands German chocolate" and on one of the balloons it says "German cocoa".
I like the fact that a horse and boat thing has the same size balloon as a person.
That it they were positive the future would, uhm, find a way.
