We (me in particular) may need a recap in the future on how this works when it's going up there. It is such a weird technology, it deserves a few more video's just for that.
I had one of those toys in 1983; when I met my ex wife she was fascinated by it. but I warned her not to break it as there is a very poisonous gas inside which destroys the oxygen in the room if it escapes. Anyway, a few months went by, I went out to do some metal detecting one day. I came back, and noticed all the windows and doors in the hose were wide open. (It wasn't a particularly warm day either). I went inside and askey why they there all open. She said. "Sorry, I broke that thing of yours on the windowsill while cleaning! I didn't want the gas to poison us.... 'her and our baby'. "So I opened all the doors and windows to let the gas out". Then I remembered what I told her about the toy.... God, I laughed so much, I was nearly crying. I then told her, that I said that so she'd be careful not to break it, and it was just ordinary air inside it. She saw the funny side of it in the end........
@@takanara7 I doubt it would've made any difference to the stupid woman. One after her broke a very delicate cobalt blue globe flower vase for holding a single rose. That moron broke that (even though it was inside a cabinet), plus two other sentimental glass tankards that I'd had over 20 yrs! All I'm sure were deliberate breaks.
The Crookes radiometer desktop toy actually rotates in the wrong direction as originally proposed by Crookes. It was supposed to show radiation pressure, should according to that absorb photons on the black side and reflect on the shiny side, and the radiation pressure should make it rotate black side forward (away from the radiation). However, it doesn't have a pure vacuum, the air molecules heat more on the black side and bounce off with more momentum and pushes it in the opposite direction (actually the edges of the vanes are important).
@@norml.hugh-mann I dare say that scaled up, the vanes and spindle could be coupled magnetically to an external 'propulsor', rotor-system or propeller of sorts, that could still 'bite' into the thin air at extreme altitudes to generate lift or thrust, although it would be interesting to see how high the system could go. The success of the Ingenuity helicopter on Mars suggests that thrust is still possible at over 30,000 metres, maybe more at even at 1 full Earth gravity. Station-keeping at altitude might be an interesting challenge.
@@mauricegold9377 No expert here, but Methinks there's no way a Crookes spinner could generate near the power required to act as a motor for a propeller spinning as crazy fast as is needed for Insight-class lifting.
@@737smartin I do agree with you here. The torque required to spin a prop at adequate RPM is unlikely to be delivered by a Crookes radiometer, even a large one. Electric motors can deliver torque at minimal RPM. I guess I was too swayed by the enthusiasm being generated in the video.
I had one of these model glass with vertical spinning panels that responded to light back in the 1960s and I thought then that it could be a great off the grid energy source if expanded and mounted on houses and buildings ! But this aerial flying device would even more amazing !
I would look to use 3d printing technology to manufacture this ultralight nano cardboard using plant cellular stoma and pigment cells as part of the matrilineal form. Also, from a botanical aspect, certain flowers appear more bright than others, even though they both produce the same anthocyanin compouunds, and this can be attributed to the petal cells surface shape ranging from conical to flat. The vacuole at the apex of one of these petal cells contains the pigment, and it too can be inflated or deflkated to adjust the cell external profile. This botanical architecture certainly sounds at a similar scale in terms of size
Didn't know that very small meteorites do not experience any heat when they fall to Earth. Nice comfortable way for microbes to get about the solar system. In so far as the end of their journey would comfortable anyway..
The black heats up and the residual gas in the bulb gets this heat transferred to it on the black side. The white side gets reaction of simply twice the lights momentum.
I don’t understand. If the sunlight comes from the top, how do you generate lift, the hot side should be pushing down. At 7:30 we see the lights underneath.
I want to know how this works with illumination from above, since the sunlight will be coming from above the lifting craft. If you are absorbing light from the top of your craft, you would have to disproportionately heat the bottom of your craft to create an upward reaction force, this seems like a non-trivial issue. The demonstration videos show the craft being illuminated from below, so not really applicable to the real-world situation. Why was this question not asked? To me this is the most interesting issue with this idea.
I was pondering this question myself, I am wondering if the answer is simply two layers, the top being transparent to infrared, and the bottom being super absorbent, with an insulating layer between, probably just atmosphere? Maybe it is that trivial, but I would like this explained by the expert.
@@tylerhloewen well, if you see the little lightbulb toy you'd notice that one half is spinning towards the light and the other spinning away, it's because it's only one side of each blade that's coated with the black coating, so that when the blade spins towards the light it's not affected by it because the darkened side is facing away from that light The idea with this floater is to use the reflected sunlight coming from the ground to provide the lifting force against the bottom of the craft, the top won't be coated with such material so the sun doesn't affect it from above and the object maintains that pressure difference that helps keep it aloft
@@tylerhloewen Well yes, the structure is thin enough to be transparent to the incident radiation and the bottom black layer absorbs it heating up. Igor explains it here: th-cam.com/video/5X4br9lqdJU/w-d-xo.html
Yes, I don’t think you could rely on just the balloons for the nighttime theory, because as it rises higher at some point the balloons, I believe, pop or fall back to earth if memory serves me right
Most balloons used in research to pop at a designed altitude, but that's because they're designed to profile the atmosphere on the way up, and then they need to come back down in a known time and area. Amateur picoballoons can stay up for many weeks, long duration high altitude balloons can stay up months
I'm just a crazy old guy, but if you made this in a sort of frisbee / wing shape with a bit of fan blade on top and a funnel down center, you could create lift from spin with a vortex jet down the center. This would also provide a stabilization from rotation. Air will flow down the surface toward the outer edges and center if it is convex in the middle and concave in the center causing upward thrust from rotation picked up from whatever wind is available at that elevation. I am trying to develop a kite which does this and then channels wind down a tube to a turbine generator, most places have sufficient wind for running a turbine, but that wind speed begins about 100 feet off the ground. If you develop the appropriate design it can revolutionize energy production as a bonus.
Remember, Mars’ gravity is 37.6% of earth gravity, & the atmosphere is primarily CO2, so balloons should work on Mars. Balloons are CHEAPER than most of the other stuff we’ve sent to Mars!
Did you say levitate? I was obsessed with crooks radiometer in grade school. And my sitter had one. I just bought one of Amazon 5 minutes ago. Thanks for the memory’s and this new future model of discovery.
The air scooping ion engine would be in space most of the time and just dip into the atmosphere a little bit at the perigee to do the maneuver burn and scoop up some propellant. You'd have a long time to collect solar energy before the next time you dip into the atmosphere and the apogee would raise each time. I think the main limitation would be needing a long time to build delta-V and the plasma erosion. What if the overhead satellites whizzing by at a regular interval could replace the sun by zapping your craft with a laser for a bit to get you through the night?
Air-breathing ion engines on satellites could prove to be operating on a knife edge, especially at first. Also, as far as I recall, the current designs make no attempt to store fuel, but instead just use it as it passes. As for remotely powering such a thing, it's absolutely possible, though likely doing that would prompt the use of e.g. a Helicon double-layer thruster to eliminate plasma erosion from concern. You would want enough power satellites to guarantee sufficient power during high criticality periods when the vehicle was being boosted.
This technology is physically possible with long carbon nanotubes to conduct and spread static electricity and provide rigidity. A parachute, bell shaped design with a small central hole to inlet cold gas to supplement what does around the sides. A flap to seal at night using static e adhesion to turn into full parachute, would require electrical isolation from main body for that structure. For us humans to do this will need bacterial synth, tech that's maybe 50 years away.
This podcast? Really excited my mind. If this can be achieved and the science or data collection and transmission of data can be done then many doors will be opened. Less invasive methods of data collection are needed. The rockets we use to reach outer spaces are huge polluters. This interview points to nasa not having anti gravity machines......i think. My 2 cents are not based on scientific evidence but observation and my processing unit. Lol. Regardless its facinating to me.
So electrostatic unfurling in vacuum, but how does it go down from geostationary? Never mind, a huge thin object slows down there pretty quick. But radical damage will be a severe. The jet propulsion thing is smart though, will probably need unique geometry to allow inflow of cold gas that doesn't crush the fabric. I pity the seamstress who has to sow this though..
To be honest, I hope they can use these wonderful eyes for Venus research. There are no humans around on Venus to report a UFO. Having these devices on Earth would just invite more media noise…
I wonder if the magnetic waves spoken of that are excessable in that part of the atmosphere continue through all parts of our atmosphere and are only excessable in that part or they only exist in that part?
1:58 Levitation to me is counterwise the magnetic force of that planet. Where fly is not included in like rockets, helicopter, or static-ionization flow.
The higher you get, the more likely it is that the field gradient is pointing towards Earth's surface rather than parallel to it. Similar to approaching the poles at high latitudes. This causes the compass needle to dip downwards until it eventually scrapes the bottom of the inside of the compass. You might need a compass that was better engineered than most to be useful at high altitude. As for how far you can get from Earth and still have a compass point at a pole? I dunno. It might be easier to look out of a window and locate the appropriate snowy bit of the planet.
Could you give these photophoretic .. objects a periodic boost during the night with ground-based lasers or a balloon array? Maybe use infrared to avoid light pollution ?
I hope the advertisers don't see this. I can imagine them creating posters, km in size, that float in the sky above our heads. At least in the sunshine.

What moon's have incredibly thin atmospheres where this might function? I know Triton and one or two Jupiter's moons have a residential amount of atmosphere
I presume that these floating objects would be entrained in the atmosphere and so somewhat geostationary. Does that make it possible to power them with microwave radiation beamed from an array of ground stations?
There's a broad swath of altitudes too high for balloons, but too low for rockets. You don't have that hard of a vacuum in those areas, but we have almost no way to study it.
Cool sounding technology concept, but I have littering concerns, at a time that we're finding "forever chemicals" contaminating every raindrop (and can even be found in our blood according to a Guardian Science weekly podcast episode, 28th of February 2023, and linked to female infertility), along with micro-plastics in our food chain.
I'm currently not impressed that the non-stick coating is peeling off my oven tray, which is the replacement for the previous one which did the same thing, except this one has done it in less time than the previous one. I don't want PFAS in my pizza.
@@massimookissed1023 I switched to carbon steel and cast iron a long time ago, there are some sub reddits dedicated to cooking with carbon steel and to cast iron cookwear. It lasts a lifetime (cast iron/carbon steel) and I think that it cooks better on the whole, especially on induction cookers, or gas hobs, some of the cookware works well on BBQ/grill too. You pick up pieces really cheaply if you don't mind used, or buy newer products.
Everyone has a smart phone that they carry everywhere with them, talk into and use to communicate all their private information. Why would you want to use anything else to track people with?
@@frasercain Of course I myself would not want to track people, but intelligence and law enforcement wants no place or person to be free of observation. So, I imagine they would develop technology so their all-inclusive information included those off-the-grid, those not carrying a smart phone, or those making some other effort to live free from tracking. They'll use it to spy over other countries etc. Just noting this...the privacy shipped has sailed. We will never be unmonitored again, we can't put genie back in the bottle. But I do treasure the memories of life back before monitoring and tracking. It was such real, pure freedom. We essentially have collars on our necks now. I'm sad that kids of today will never know, experience, or value such a way of existance.
Awhile back I read about a solar sail they were working on that was black instead of reflective. Cool stuff! I wonder if you could use some sort of static structure to get to the proper height, something like the spider silk made structures spiders construct to fly?
Could this be used to carry a single person? It would be a good alternative to a car or a bike and an amputee could use it, plus fulfill our dreams of flying.
It would have to be absolutely massive. Such a thing might eventually happen, but it will be far in the future, and things like Dark Sky Station are likely to happen far sooner than that size of these devices. As for flying, I'd rather point people at the Aeroplume in france.
@Mark Purcell that's my point. The radiometer heats up on the dark side, which is facing the energy source, which heats up the small amount of surrouning air (or low pressure gas), and it spins, away from the energy source. Which is the expanding air, from the dark side, facing the sun.
@@DingbatToast The black surface is on the bottom (opposite side to the sun), the whole stucture is thin enough to be transparent to the incident radiation so the bottom side heats up despite the sun being on the opposite side. Here's the more detailed explanation from Igor's TH-cam presentation, he states it doesn't matter which side the LED (i.e. the radiation source) is on. th-cam.com/video/5X4br9lqdJU/w-d-xo.html
@Mark Purcell thanks for the link. I hadn't imagined the material to be transparent. The demos in the video you linked do appear to prove the concept. Although a have my doubts that the temp difference will be ennough if the sun has to pass through the material first. I would be more convinced had he produced a small levitating model/sheet that was energy sourced from above, rather than the more efficient radiometer in the jar. Still, small steps. I will follow with interest!
Fraser, try to notice how eager you are to get into the topic of flying saucers as long as it doesn't upset your pedestrian worldview. Dare to deal with the evidence for the real thing. Being in stubborn denial out of sheepish fear is not good enough. Follow the evidence.
I'm unconvinced by the current quantity of evidence that there's anything unusual going on. But I'd gladly change my mind when new evidence presents itself. I suspect there are things I believe that you don't believe, and that's totally fine. But you don't see me insulting you about it.
Yes, the grant is to develop the technology to the next stage. That's how all the NIAC grants work. You're seeing the technology landscape that NASA is investing in that will fly on missions in the coming decades.
Sounds like the idea would be a paper thin computer, spread out over the entire surface of this very lightweight vehicle, which uses ultra small sensors and observational tools. Can anyone say "Spy Tech"?

Temperature gradient causes convective air currents. That toy doesn't work with a very hard vacuum.
There's a broad swath of altitudes too high for balloons, but too low for rockets. You don't have that hard of a vacuum in those areas, but we have almost no way to study it.
I thought that was Lewis Capaldi for a second
Here’s a question that just came to mind: what would Mach 1 be on Mars?
About ⅓ of Mach 1 on Earth.
240 m/s vs 750 m/s
"The Solar winds WILL catch the sail"
I wonder if tgis tech is a good candidate for high altitude Venus
Doh.didnt listen before shooting my mouth off😅
Yeah, we had the same thought. :-)
Stack the floaters and you could build starway to heaven
Yikes, you climb first.
As a scientist mind I want to study this technology
Cool sounding technology concept, but I have littering concerns, at a time that we're finding "forever chemicals" contaminating every raindrop (and can even be found in our blood according to a Guardian Science weekly podcast episode, 28th of February 2023, and linked to female infertility), along with micro-plastics in our food chain.
I'm currently not impressed that the non-stick coating is peeling off my oven tray, which is the replacement for the previous one which did the same thing, except this one has done it in less time than the previous one.
I don't want PFAS in my pizza.
@@massimookissed1023 I switched to carbon steel and cast iron a long time ago, there are some sub reddits dedicated to cooking with carbon steel and to cast iron cookwear. It lasts a lifetime (cast iron/carbon steel) and I think that it cooks better on the whole, especially on induction cookers, or gas hobs, some of the cookware works well on BBQ/grill too. You pick up pieces really cheaply if you don't mind used, or buy newer products.
April 1st surely
Drop from micro sats, that charge the balloons with liquid hydrogen and then let them come down
how can be photophoresis in a vacuum? shouldn't it be called something else? like photokinesis?
Ah, another way to monitor track the people.
Everyone has a smart phone that they carry everywhere with them, talk into and use to communicate all their private information. Why would you want to use anything else to track people with?
@@frasercain Of course I myself would not want to track people, but intelligence and law enforcement wants no place or person to be free of observation. So, I imagine they would develop technology so their all-inclusive information included those off-the-grid, those not carrying a smart phone, or those making some other effort to live free from tracking. They'll use it to spy over other countries etc. Just noting this...the privacy shipped has sailed. We will never be unmonitored again, we can't put genie back in the bottle. But I do treasure the memories of life back before monitoring and tracking. It was such real, pure freedom. We essentially have collars on our necks now. I'm sad that kids of today will never know, experience, or value such a way of existance.
Awhile back I read about a solar sail they were working on that was black instead of reflective. Cool stuff!
I wonder if you could use some sort of static structure to get to the proper height, something like the spider silk made structures spiders construct to fly?
Could this be used to carry a single person? It would be a good alternative to a car or a bike and an amputee could use it, plus fulfill our dreams of flying.
It would have to be absolutely massive. Such a thing might eventually happen, but it will be far in the future, and things like Dark Sky Station are likely to happen far sooner than that size of these devices.
As for flying, I'd rather point people at the Aeroplume in france.
Where do the amputee park this vehicle when it is not used?
Really interesting stuff 👍 ignore the know it alls 😂
You didn't ask him if he'd let you know when they levitate a full scale production :(
❤️🖤❤️
Ya..in tuv
I'm trying to get my head around this... Is it essentially a solar heated hot air balloon?
Basically, though to understand the shape it's probably better to imagine a parachute getting grabbed by an updraft.
Doesn't this cause a force away from the energy source? So if that source is the sun, the vehicle will be pushed down towards the earth 🙃
No, this is not using radiation pressure. The Crookes radiometer rotates in the opposite direction to that too.
@Mark Purcell that's my point. The radiometer heats up on the dark side, which is facing the energy source, which heats up the small amount of surrouning air (or low pressure gas), and it spins, away from the energy source. Which is the expanding air, from the dark side, facing the sun.
@@DingbatToast The black surface is on the bottom (opposite side to the sun), the whole stucture is thin enough to be transparent to the incident radiation so the bottom side heats up despite the sun being on the opposite side. Here's the more detailed explanation from Igor's TH-cam presentation, he states it doesn't matter which side the LED (i.e. the radiation source) is on.
th-cam.com/video/5X4br9lqdJU/w-d-xo.html
@Mark Purcell thanks for the link. I hadn't imagined the material to be transparent. The demos in the video you linked do appear to prove the concept. Although a have my doubts that the temp difference will be ennough if the sun has to pass through the material first. I would be more convinced had he produced a small levitating model/sheet that was energy sourced from above, rather than the more efficient radiometer in the jar. Still, small steps. I will follow with interest!
Payload, what's it going to be then, a cat flea and 2 dog fleas. Frazer this is bloody ludicrous.
They can use trained circus fleas. They're mostly unemployed these days
Sounds like a great potential hogh security prison
Payload capabilities?
👍👍
Thanks!
It’s called a radiometer
❤
that faint background music irritates
In the future all the crackpots who say they saw a flying saucer you can now respond to:
- Duh! They are all over the place.
Test.
4 months later
Thumbnail Lol ...butt his could
Heh heh, you said "butt".
@@frasercain You said "literally" in the title. A bit misleading.
A Carpet can help !
is it possible to make the saucer like layer cake but the shape is a droplet of water on a smooth service.
Dr Igor Bargatin really doesn't want anyone to know about his surroundings...
The region these fly in ,could they somehow accelerate green house gases to escape velocity ,with some sort of payload, ?
Fraser, try to notice how eager you are to get into the topic of flying saucers as long as it doesn't upset your pedestrian worldview. Dare to deal with the evidence for the real thing. Being in stubborn denial out of sheepish fear is not good enough. Follow the evidence.
I'm unconvinced by the current quantity of evidence that there's anything unusual going on. But I'd gladly change my mind when new evidence presents itself.
I suspect there are things I believe that you don't believe, and that's totally fine.
But you don't see me insulting you about it.
Nothing deployed yet so it's ......theoretical
Yes, the grant is to develop the technology to the next stage. That's how all the NIAC grants work. You're seeing the technology landscape that NASA is investing in that will fly on missions in the coming decades.
@@frasercain if the probability of success is above 10% then definitely worth funding
21st century and snake oil is still on sale..🤔
23:45 I’m trying, but your guest sounds so unenthusiastic about the topic.
Misleading title.
too much on the application, lets talk about the "device" ?
Sounds like the idea would be a paper thin computer, spread out over the entire surface of this very lightweight vehicle, which uses ultra small sensors and observational tools. Can anyone say "Spy Tech"?
