SEAgel Aerogel lighter than air solid. Not a UFO

[@aaronsmith2054]

Thank you for this clip I remember watching it on TV as a kid. I loved that show and always remembered this clip.

[@henzehe]

If the SEAgel was lighter than air, it would have floated to the ceiling. It is LIGHTER THAN THE DENSE GAS IN THE CLEAR CONTAINER HE DROPS IT IN! This gas is certainly not nitrogen since nitrogen is slightly less dense that air and would therefore rise out of an open topped container. This same demonstration is regularly done with a foil "boat" in a similar sort of aquarium type of container filled with sulfur hexafluoride gas which is likely what is used in this demonstration.

[@ericounderdown6110]

It is a lighter than air solid. The problem is that it is not airtight. The solid is 'filled' with air making the combination (air + SEAgel) heavier than air. If the SEAgel was made airtight in a vacuum so that it contained no air, it would float in/on air.

[@joshuagutierrez7706]

Technically, air is in that chamber. Get over it.

[@abrinks]

I believe that in the video they said the container was filled with nitrogen. Nitrogen is what makes up roughly 70% of "air". So............... Please. Calm down. Breathe. Relax. Get your facts straight and pay attention to the video instead of assuming things.

[@motthubris5122]

air is a technically relative term and is qualitative, as gas mixtures' (in earth's atmosphere=definition of air [which is stupid because if you were on a planet with comfortably breathable gasses, or in a spaceship, then you would still call it air]) density (quantitative) varies widely depending on factors such as composition, temperature, longitude, latitude and altitude. However, meeting the definition of unaltered "air", this solid would not float.

[@ViaStrata]

My guesstimates: The "air" in the container was cooled down using liquid nitrogen because it was the most handy way to get the space inside the box to cool down. The space filled up with ...let's say -50ish °C gaseous nitrogen. That way you get the nitrogen gas denser than air. Air is around 78 % Nitrogen. Air at 20 °C, normal pressure: ~1.2 kg/m³ Air at -20 °C, normal pressure: ~1.4 kg/m³ Air at -100 °C, normal pressure: ~2.25 kg/m³ Let's assume the nitrogen in the box had a temperature of around -55 °C, that would give it a density of ~1.6 kg/m³. The gel had a volume of approximately 40 ml. If it where 100 % air at room temp that would give it a weight of ... ~0.0012 g/cm³ x 40 cm³(aka ml) = 0.048 g The air inside the gel weighs ~48 mg. Same calculation for air (78% nitrogen) at -55 °C gives you a weight of 64 mg. If the gel (without any gases trapped inside) had a weight of less than 24 mg (lets make it less than 20 mg) which gives it a density of ....24/40..0.6mg/cm³..0.0006 g/cm³...0.6 kg/m³...it could float on moderately cold nitrogen. (They still probably saturated the seagel with helium or hydrogen.)

[@ZionistWorldOrder]

Perhaps even a small amount of aerodynamic lift as can be sufficient, myees :D NASA has been planning to sample lighter gases using aerogels, also pollutants are captured/ filtered using aerogels. I dream of a personal airship with pedals & solar cells, 8m*4m*3m of helium trapped in even spaced aerogel compartments. Would not that be the 1. time helium DIDN'T escape an airship? A few 3L water-ballast containers on electric rails for attitude control when hovering. Maybe even add a hot air compa

[@arbpotatoes]

He did say that it was 'air made thin by nitrogen gas'. It's probably a nitrogen/oxygen mixture.

[@roidroid]

the friction of it moving through the air would soon bring it to a stop, it's like a helium balloon.

so if you made a small light aircraft out of this would the friction of it moving through the air create enough static to keep it in the air?

[@MrBrofo1]

No

[@bfeezey]

Next step!! I loved this show! They made a huge inkjet printer out of pvc once. good times

[@Primu]

@robinheil It's lighter than aerogel though. They're both pretty useful in their own sense.

[@Playbahnosh]

aerogel can support 4000 times it's weight, but since it's structurally very brittle, it needs very precise measurements and positioning. for example a small 1by1 inch perfect square of aerogel can support a normal sized brick, if placed precisely that is.

[@JIHOJIJO]

how's it actually floating in air?

[@DeimosSaturn]

Yeah, my guess is they are using this stuff for robotic blimps. Blimps that are hybrid lighter-than-air aircraft and traditional fixed-wing aircraft. Simply by changing its orientation it changes its mode of flight. It's got to be stealth too because it probably traps radio waves in its pores. A blimp that is not a bladder of hot air, but a solid sponge less dense than the surrounding atmosphere.

Patents refer to such an aerogel material has having microscopic vacuum chambers via a freeze dryer.

[@lepape2]

Look for Aerogel on Wikipedia, a lot of different types exist. The silica nanofoam is the lightest. Quote: "Silica aerogel holds 15 entries in Guinness World Records for material properties, including best insulator and lowest-density solid."

[@mmbleachtasty6121]

INCREDIBLLLLLYYY britle

[@hiimemily]

@frenchfrys12 Well actually, let's assume 400 kg of this aerogel would crush you. Since this is lighter than air, let's just assume its density is 1 mg/cm^3. That's 4 x 10^8 cubic centimeters, or 400 cubic meters. That's practically a house full of the stuff!

[@slowlybutfasholy]

If two cars made of this got in an accident it would be like crashing into a cloud.

[@avada0]

I don't think they can be made light enough to be usable as airships. This can barely float it's on weight in special circumstances (heated). Airships need to carry payload in freezing temperatures.

[@centpushups]

a sticky food that does not leave residue. excellent. bonne video

[@ProPuke]

if the average density of the object (mass/area) was less than that of the surrounding mass (air) - then yes, it would float. You'd need a lot to offset the weight of the engine, & drag the density back down again, thou. (rather like the way blimps have massive balloons supporting them) Doesn't seem to say if the stuff is actually _lighter_ than air (or just close) thou

[@skribbzo]

why dont they use this for pool toys and floatation devices? hell, i wish i had 20 square feet of it

[@DigiTan000]

Either a light snack, or a square meal.

[@strongback6550]

Seems like you could use this to block direct energy weapons without adding weight.

[@ZionistWorldOrder]

rtment to go lighter than air & heavier than air to tip the balance at will, heated by HHO ofcourse. Sitting on my seat composed 98% of batteries i'd have my feet on the pedal dynamo :D The propeller & 100W "inwheel" electric motor would be on a rail going from over the ship to the front for forward & upward motion(& inbetween) The "inwheel" would also generate electricity when exposed to winds/rapid descent- unless in use. Aerogel is expensive but optimum for heating & flight. Any dreamers? ;D

[@Grommo]

The pilots and passengers and engines of airships are effected by gravity too don't forget but they still fly. The dense components simply have to be a significantly smaller percentage of the total size of the object so that the bouyant components can lift them. Making a craft only neutrally bouyant in the atmosphere means that a small amount of aerodynamic lift from forward motion could still make a craft fly easily.

[@beansavacado8134]

Interesting. Very.

[@MinecraftGamingCrew]

dear Santa....

[@cr9527]

@volound Nothing can contain a vacuum. Vacuums do not exist. Lead also wouldn't be strong enough to maintain its shape while trapping a near-vacuum state

[@thomasciarlariello3228]

If sealed in a metal foil such a material could replace rail transit trains to consider how rail transit tracks were bult upon Coolies and how rail transit tracks are used to subjugate.

[@Grommo]

Interesting with trains its not so much their rolling friction that is a limit to their speed but their air-resistance. Same with cars. A hovercraft is much less efficient than any car even with no rolling friction. A maglev train is presently expensive to build. Interesting the potential uses of this aerogel/seagel technology!

[@thomasciarlariello3228]

What I am also referring to is how a lifting body airship could haul spaceplanes up to speed and altitude for orbital launch and to tap cosmic ray muons for nuclear fusion rocket propulsion since of March 2019 I was a guest speaker for an invite only engineering conference held inside MIT's Electrical Engineering Dept. on Vassar Street where I gave a presentation on nuclear aerospace propulsion.

[@thomasciarlariello3228]

A maglev monorail train trolley is a moronic waste of helium.

[@thomasciarlariello3228]

By curving an underside of a land vehicle from a horizontal front to a vertical rear a land vehicle of metal foil sealed SEAgel could allow skimmers or hovercraft to make other infrastructure obsolete for those cold plasma highways of Wachouski's "Neo Seoul 2144 A.D." . Metal foil sealed SEAgel could allow towers to extend into orbit for cryogenic Tripler air liquefier cold boxes of chemical metallurgical industries or even improve continuous extraction fractionation columns of refinery retort distillers.

this isnt a solid. it is a solid containing a gas. according to this logic, lead is lighter than air because it could be made thin and contain a vacuum.

They use it in astronaut space suits. Because it is an excellent insulator (i.e., it's like the greatest blanket in the world!) , and outer space is really, really cold, by using this stuff on spacesuits, astronauts are able to use it to walk around in space and stay warm! Also good for keeping your feet warm! Search "ToastyFeet" in google!

[@Gwalchgwyn]

That's a two year-old comment - he died shortly afterwards from drinking water because he wasn't around at the big bang to see the first hydrogen atoms created, so every atom ever synthesised from its fusion into heavier particles gave him cancer by the process of spontaneous psychosomatic chromosomal corruption exacerbated by previously undiagnosed trisomy. It's a sad and terrible story rather blandly titled, "If I didn't see it made, it'll give me cancer! The short, tragic life of Jonny Derp."

I'm pretty sure they said it was filled with gases that are lighter than air (helium, hydrogen). What is your logical basis for your conclusion that the tank is filled with a gas more dense than air? Is it just a hunch? Or, do you have a scientific deduction?

Your argument is pretty bad. Aerogel and seagel are two different materials. Properties in one will make it better suited for an application than the other. Your argument would be similar to insisting that molybdenum is worthless as a filament material because tungsten is more durable. Its the application that counts.

What could be a substance for space elevator in a future.

[@Grommo]

Could be for some parts but high tensile strength and would be first requirements as an elevator needs to start at geostationary orbit and then descent from there. If we built a tower as tall as the orbital height of the International Space station or original shuttle orbits it would still have about 95% of normal gravity at the top. Microgravity in the ISS is a result of its orbital speed , not its altitude.
