[@touchheartyoga]

So wasn't there some development on a skin for the vehicle that produces its own electricity from the movement of the craft? I could be mixed up here. But either way, I'm confident that the same technology will open the door to partial capture for electrical generation.

I think there may be an active shielding application for reentry vehicles. Watching starship form a plasma sheath made me think we could try deflecting the plasma as a way to heat shield the vehicle. May also apply to hypersonic aviation

[@everettstormy]

[@seagie382]

Initially they wanted to drop the heat tiles and pump fuel mist into the plasma to form a sort of bubble

[@FelonyVideos]

I like the way you think. That is novel. Hi IQ style. But... As it happens, the only reason there is a plasma around any reentry vehicle is because the speed of the vehicle versus the air. The leading surface hits the air molecules so fast it heats them to the point of kicking loose their electrons, making said plasma. 1mm before striking them, they are not ionized, so no magnet or electric field can move them out of the way. But it gets worse. The air is actively being used as a brake. If it was possible to move the air out of the way, the ship would have no braking, and would "land" on the surface at 17,000 mph. We prefer 0 mph as a better landing speed. 😂

[@DS-vu5yo]

@@FelonyVideos not debating the cause of the plasma…. But plasma is generally conducive regardless of how it is produced. A pulsed field should be able to be produced that would not only reduce the heat on the tiles- but actually increase the resistance by pushing the plasma out. The heat would of course be absorbed by the generator creating the field…. So no free lunch- but maybe an optimization exercise.

[@aelisenko]

@@FelonyVideos I was thinking the air would initially go through the magnetic field, hit the vehicle and start ionizing, once the plasma layer develops the magnetic field would create a cushion between the plasma and vehicle. At those speeds I don't think the magnetic field would be able to delfect anything just force the plasma off the vehicle slightly, creating an insulating layer. This would likely create a large pressure differential so it would be interesting to simulate the overall effects to the vehicles aerodynamics

[@oxjmanxo]

One of my favorite types of shields is a gravity shield. Fucking around with space time in front of your ship so projectiles curve away from your ship. The drawbacks are you need to predict where your enemy is going to shoot. You can’t throw it on reactively as by the time you see a relativistic projectile or laser it’s already too late. You also run the risk of curving an otherwise glancing blow into a bullseye. Battles turn into a contest of who’s gunners can outwit the opponents shielding.

[@bendybruce]

@@oxjmanxo LOVE IT!

[@oxjmanxo]

@@bendybruce a variation of this was a gravity hammer. Why not turn the bending of space time in your shields into a weapon? Turn the gravity up to 11 within the enemy ship. You can add distance limitations to make this a short range use only thing. These are all variations on how to use the classic gravity generator tech in different unique ways.

[@tomardans4258]

Any astronaut caught in the blast would, of course, develop superpowers.

[@MyrddinE]

I'm sure it's covered in more detail in the actual paper, but it feels like th shadow would be offset by the increased brightness when the protons are deflected into the unshaded areas; a shadow doesn't provide 'shade' if most of the light is still reaching the surface. This feals more like it creates caustics, like light ripples on the bottom of a pool. Sure, the dark areas are darker but the light areas are brighter leading to the same overall radiation exposure. I'd be happy to be wrong.

[@thorzweegers7616]

Exactly.... where are they deflected towards?

[@bobbygetsbanned6049]

I highly doubt particles moving that fast are going to get deflected and keep moving in the same general direction unless they hit the very edge. Shining light on a mirror shines the light back at you, not on the wall next to the mirror.

[@JB52520]

@@bobbygetsbanned6049 Deflection and reflection are different, though. Deflection just needs to push the particles to the side a bit so they can continue on their way. I had the same concern about caustics but didn't think to call it that. If those electrodes are just nudging the particles to areas between the shadows, then it's no improvement. If the astronauts sit in the same place frequently, it would focus the radiation on smaller areas of their bodies, increasing the risk of cancer. But like the OP, I'd be happy to be wrong.

[@dominicsimone]

If you're merely deflecting the particles, then aren't you just concentrating them into the non-shielded parts of the pattern? I suppose if you stacked enough layers of this matrix, then the " tortuous path" you created would have equal probability of reflecting or letting through any given particle?

[@-_James_-]

Surely if you deflect through the first layer, the second layer would just deflect back into the spaces protected by the first layer, thus solving nothing. What you actually need to do is deflect the particles into channels that flow around the ship and back into space.

[@everettstormy]

I wander about catching some of the particles to generate power​@@-_James_-

[@simleek6766]

Yep, you can see in the image that it's brighter in between the non-shielded parts. In that case, you'd probably want a cone of circles of points, with the smallest circle/point forward most, so that any particle can be deflected entirely around a habitable area, like how the some of grid particles were deflected to the outside. Alternatively, you could only protect the parts of a ship that needed to be protected from radiation, and let the parts that can handle much more radiation have much more radiation.

[@chrissears9912]

I was wondering this too, but surely JPL and NASA would have thought of this... The deflection must be a greater angle.

[@elishelton9412]

Yeah I noticed this too, it’s not sending the particles 180 degrees back the way they came, it’s only throwing them a few degrees off and funnelling them into more concentrated areas between the gaps.

[@caeli5532]

I think that to test this shield around the earth, there are enough radiation belts, inside which satellites like SUBESAT can be launched, which can then be returned to the ground and their surface examined under an electron microscope for radiation damage.

[@skyrat3816]

Was thinking the same thing with the van Allan belt (may have spelt that wrong). However, it's going to be down to having a launch vehicle to get prototypes there and could well be achievable once starship is able to take payloads into orbit and possibly bring them back for testing.

[@Cyber-Riot]

Ideally, we'd want to "capture" these particles, and translate their energy to into usable power for the craft.

[@JB52520]

I think it would take more energy to accelerate them to match the spacecraft's velocity than whatever energy could harnessed from their charge. But maybe they could do some work on the way by. (Honestly I don't know. Physics is not my forte, it's just fun to think about.)

[@rafaelgonzalez4175]

Ideally we need to resolve the radiation issue of the cosmos before we dive into the radiation of the cosmos. One main reason why deep space is off limits. Absorption of radiation. Passing through the lowest density of the radiation belt was a mission. Dealing with direct radiation now. Deep space. Anything outside of Earth's Radiative belt.

[@JohnDlugosz]

Another reason for discounting the electrostatic approach, even for energies that are doable, is that some particles have the opposite charge.

[@Nidvard]

protons always have a positive charge, that's the definition of the proton. If it had negative charge it would be an electron. For charged ions, they are charged as electrons are stripped away, making them positive charge. So no, no opposite charge.

@DrBenMiles as an accelerator physicist, by and large I liked your video. However, I do have a comment about you saying what is achieved by old school particle smashers only being in the MV range, especially when showing what appears to be a synchrotron animation. What you said was true about electrostatic fields ie Van de Graaf accelerators, etc. However cyclotrons and synchrotrons are not limited to the MV range. Otherwise we wouldn't have TeV protons at LHC at CERN. The difference is time dependent fields in microwave cavities, that can get up to TeV energy gains with a closed loop or GeV energy gains in linear systems like SLAC. If you were, however, talking about accelerating gradients, in units of energy per unit distance, MeV/m, for example, you would be roughly correct. Our best microwave accelerators still only have gradients around a few 100MeV /m. Luckily we have plasma acceleration, dielectric accelerators, etc, which push the gradient up to GeV or even TeV per meter. It may be possible, with enough plasma density and energy in a laser pulse or particle beam, to get up to EeV or ZeV / m gradients before the high energy density physics gets so interesting that the plasmas are too unstable to provide that gradient over an appreciable distance. Good luck out there!

[@l.clevelandmajor9931]

Someone is going to say "Awesome! We have energy shields now!", thinking that these shields will protect our spaceships from enemy weapons fire. NOT! This shielding will only deflect harmful particle radiation, up to a certain energy level. It will not stop lasers, missiles, bullets, fast moving meteors, or even slow moving ones. And if the ship is on a collision course with an asteroid, better change that course as quickly as possible; otherwise the ship will be like a splattered bug on the surface of the asteroid. For particle radiation deflection, this is actually a great breakthrough. As we continue to develop the technology, it will soon be miniature enough to be practical on all spacecraft. The biggest obstacle to its practicality is at this time, weight, which adds more to what the ship's thrusters must accelerate to the desired speed, meaning more weight in the form of fuel and its containers. Now there is some promising experiments concerning massless thrust, but it is still in its infancy! Still there have been some small amount of successes in the studies and experiments. If these two technologies become practical, and can be used in one ship at the same time, it will revolutionize the space travel industry.

[@Nidvard]

Weight of the system is one thing, but also the weight of any energy production to keep this up. To get the weight into place can soon be done rather easily when starship becomes viable. And if this is used for a interplanetary transport system the logistics of weight becomes less significant, also because such a transport system can be set to an continuous orbit with intercepts both earth and mars

[@jgbreezer]

If you also build a deflector a ways out ahead of the direction of travel, say on a long boom, you don't need to deflect the particles as strongly for the particles to miss the vessel (as long as you don't deflect any particles that would otherwise miss, onto the vessel). That also protects the vessel from any magnetic/electric fields used, though obviously means more assembly/risks of damage and disconnection through the boom.

[@hatac]

There are two other older designs that I know of. I have the papers somewhere but I'm moving house so they will be impossible to find for a while. One used long kilometer diameter cable loops with charge flows producing a big but low power magnetic field. This trades size for mass and complexity. Field strength is low but the large field means the particle is pulled to the center of the loop. The habitats are close to the loop. There are too versions. One standing on poles on the moon protecting habitats there and one held circular by cable based mass torsion systems. Two counterrotating cables tethered to the other. Centrifugal force holds them circular at low mass. The other proposed system clads the ship with magnetic sheets and fires a particle beam an the very low angle. The magnetic fields bend the beam around the hull forming a migma sheathe. A electron beam fired astern helps. The result is a sheathe of particles going at right angles to the hull. Any dangerous particles are either deflected or entrained. Both were in the British interplanetary society magazine years ago.

[@Ri-ver]

Awesome video, thanks for all the work you put into it! How much do we need to worry about high energy electromagnetic waves / photons compared to the high energy particles? Would we need to include additional engineering for that, or is that not as much of a concern? And if it is a concern, how much of a challenge is it?

[@Nidvard]

electromagnetic forces are carried by photons, and with high enough energy this gets into gamma radiation. This can't be stopped by any electromagnetic field of any kind, so the only way we have to shield against anything like that now is dense mass, as in lead, other metals or as starship plans it, water. Some plans (ideas at this stage) would be that certain compartments of starship with be shielded by among other things the water which is brought along the journey, so when they are at risk of coming across large amounts of gamma radiation the crew would shelter inside said compartments. This doesn't eliminate the problem though, and at this stage this is the best we got. Photons can interact with electrons however, so if any electromagnetic shielding were able to hold/lock electrons in place as an extra barrier, that could possibly help (in my uneducated guess)

[@CrossoverManiac]

Is this why the electrostatic grid requires much lower voltages than originally calculated: instead of trying to apply an equal electric force to stop the charge particle in its tracks, the grid applies a force at right angles and adds a velocity component at right angles to the initial direction of motion causing the charge particles to miss the central area where the crew is? Edit: Kind of like how judo, rather than blocking the punch, redirects it allowing the blow to keep much its original momentum except it's directed away from the person.

[@louiswhaley258]

I was wondering if the same kind of deflector would deflect electrically-neutral bits of gas and dust? It might be just as important to protect the ship and crew from cosmic rays as to protect both from micrometeoroids and microscopic space debris. Maybe if you embed the electrode array in an insulating aerogel, you can protect from both. Great video, sorry you were sick. Best wishes.

[@LearndingLife]

Perhaps finding a way to get them to work in tandem. Radiation is still energy, if it could harnessed, the deflected rays energy used to help power the magnetic shield, be interesting. ^.^

[@waxwars9183]

I wouldn’t be caught dead in a trip to mars without 30-40 meters of water surrounding the living quarters. That’s cool if you want to make a deflection shield in addition. But still need the 30-40 meters of water completely surrounding any space humans occupy on all sides.

[@necromental]

Wow, you didn't lose me once. That was an impressive summary.

[@ZMacZ]

14:26 One step beyond is the RAM-scoop. Deflect the particles into a material chamber, and expel as thrust on the back end of the vessel. Mere field tech and hardly new actually. 14:51 They can use a mere cyclotron for testing purposes. In nature NTL (near transfer of light) hadrons are unlikely. If any vessel is moving at like 0.1 LS (c) the particles they encounter the most would not exceed 0.2 LS, which can be created artificially by a cyclotron. Specially single protons. The problem isn't these charged protons, but the actual non-charged colloidal matter particles. They'd need ionisation before they can be deflected by any field.

[@pawelszarejko]

I love this video. You do a great job at explaining this stuff. Did anyone ever think to create a battery array that would hold needed charge for spacecraft while providing the magnetic shielding at the same time? Can't the battery electrodes be configured to create a geometric array that would provide the magnetic shielding needed? Taking it one step further, why not utilize the Seebeck effect as there are significant differences in temperature on lit and dark sides of the spacecraft, or between the exterior and interior. Wishful thinking on my part perhaps

[@darthrainbows]

The shape of the shielding on the electrostatic model makes me suspect that the particles that would have struck the shielded areas are simply being directed onto the unshielded areas. That's fine if you can shield the entire region occupied by the spacecraft, but layering offset shields won't do the trick. Particles that pass through the unshielded areas of the first layer would get redirected into the unshielded areas of the 2nd layer. The only way laering would work is if you can preferentially redirect incoming particles in one direction. Each layer redirects away from the spacecraft in the center, so whatever particles that get through one layer have a chance to get redirected away by the next. IDK if that's possible or not.

Uhm pretty sure we are already fielding experimental plasma shield on the battlefield. I read an article saying that boeing had a system it was testing on abrahams tanks. Its thin panels of explosive charge on all sides of the tank and some kind of radar or ultrasonic detection system surrounding the tabks peripheral. When it detects an incoming rocket, it detonates the plates facing the munition, yhis produces a shockwave of compressed atmospheric gases. Then microwave emitters send out a powerful pulse in the same direction, the pulse ionizes the shockwave of compressed air creating a wall of plasma that detonates the incoming munition at a safe distace that wont penetrate the tank armor. Im not sure if they are fielding this yet or if it was just in testing stage, but i do remember it was boeing that was developing it. Not sure how useful it would be in space without atmosphere to create plasma but it's still pretty interesting tech for here on earth, hopefully they find something more positive to use it for besides warfare 🤷🏽‍♂️

That's a very interesting documentary!

[@diddykong3100]

The other problem with electrostatic repulsion to stop charged particles, aside from the crazy high voltages needed, is that what stops things of one charge only makes those of the opposite charge worse. Magnets can bend both types aside - albeit to opposite sides, but that's fine.

[@diddykong3100]

So doubly cool that someone worked out how to navigate round the problem ;^>

[@NoGreedSeeds]

Thanks for dumbing that down enough to be informative AND entertaining. Very consumable content, for such a deep and complicated subject. I’m still waiting for ge and cern to get together and create that time travel machine that Titor was talking about…. 🤷‍♂️🤯🎯😝 ANY DAY GUYS! GET ON WITH IT!

[@nickgirard9018]

What if we did this for earth? Active shielding for the planet (slightly diverting particles in a cone by diverting particles with large magnetic power would be a great start in reducing the risk from serious solar storms.

[@cjhsuliman13]

I wonder if we could absorb and harness the energy rather than deflect it. A conductive layer of shielding over an array of micro wireless chargers and a base layer of conductive shielding. A layer of h2o would further absorb any residual particles and dually act as a salt water capacitor. A regulating circuit to sense the incoming voltage and charge a stepped down high voltage capacitor bank. The capacitor(s) would then drain to charge the onboard batteries For very large bursts of energy we could include a switched drain circuit powering the tesla coil like shielding. For directed energy weapons with smaller implications a general use shield could incorporate this and power up a tungsten or quartz headlight to dissipate the energy.

[@nzoomed]

Would a bunch of strong neodymium magnets lining the habitat be enough to protect you inside?

[@Sq7Arno]

Just one problem though. The particles are deflected. Scattered. Not blocked. So the particles will all just be diverted through the gaps. Even offset, the "sieve" effect will persist. So well... Only a portion will be diverted in directions that lead them to miss, even when offset. Offsetting multiple grids may even divert particles scattered in directions that would cause them to miss, back on trajectories that will make them hit.

[@gregm6801]

Be interesting to see what they come up with...and if its possible in our lifetime .

[@arachnohack9050]

So they made an electrostatic shield at a 3M (sellotape and film) factory by accident. There's a few snippets of info about this out there, but it happened before the Internet was popular. I'd love to see a proper mini-doc on this as most vids here on KZbin are very short.

[@jamesgreenler8225]

The proper conductors and or semi conductors can do things we haven't discovered yet regarding force fields

[@stapuft]

On the note of cooling I mean the vacuum of space is a vacuum that would help insulate the superconductors meaning you would need to cool them less because every all the cooling you're doing days effective longer, now help prevent a kind of heat osmosis you also have to insulate it from the ship itself but still even with that same amount of coolant should be able to cool it for longer

[@i-love-space390]

I had heard that there was a third off shoot to the other two approaches that involve injecting a plasma into the charged area that enhances the effectiveness of the electrostatic approach because the particles of the plasma have their own mass and charge too. Could you add a video addressing this other approach? I think they call it the artificial magnetosphere method.

[@Xabraxus]

I'd imagine the optimal radiation shield would take incoming particles and immediately dump and convert all the energy of the incoming particle into spatial expansion, basically turning the kinetic energy into new planck lengths of spacetime that get spawned into the universe. How would this be accomplished? Use the energy to drag space from a 4th dimension into the 3rd dimension, the only problem is we would need an interface with the 4th dimension to do this.

[@armwrestlerjeff]

Idk how they can stack that mesh to make it cover the holes in shielding coverage because the particles are simply deflected around those nodes and would become concentrated around the second layer of nodes, effectively undoing the deflection of first layer

[@ADHSV113]

Pardon my question, but what about a hybrid or plasma approach? I was looking at active drag reduction and plasma actuators and plasma control surfaces for some of my designs and I was wondering if an embedded high-voltage/magnetic skin with said emitters would work? Especially if there was a way to print it? The idea to create an intense field to slow or redirect the particles, yes? It doesn’t need to cover the interior, just the exterior.

[@ZionistWorldOrder]

electrostatic mitigation of lunar dust and martian dust on solar panels is an old thing yet we speak today as if these are still discoveries to be made, how does that relate to shields? Perhaps these are also ahead of mainstream the way military tech is often ahead of commercial..?

[@Nidvard]

This does not relate to shields. Military tech gets their components from the same factories that produce components for commercial products.

[@timothyg967]

I would love to see the grid tested at various angles, perhaps those results are hidden for further development

[@maschwab63]

How about creating a Bussard collector to gather ions into the center of a magnetic pipe then spew them out the rear at a higher speed? Basically an Ion thruster using outside ions as reaction mass.

[@AoriDeAof]

When you told about chainmailing the effect of active shielding i thought of Heavy Object. While this piece of art is pretty interesting and fun to watch the point of my attention is the technology behind those Objects - they are sphere-shaped battle machines that have only single small (obviously gated) hole to get a pilot inside and all connections to outside world such as weapons power, mobility systems, etc. are managed thru armor - which acts as a conductor also. It cannot withstand huge kinetic impacts but is pretty much ok with plasma/photon types and now i can almost assmeble a picture why. While it is a Sci-fi the armor of Heavy Objects is not (i believe) really magical material you can cast into slabs and use as is - its is complex multi-layer onion shell - which gives me an idea we dont need that shit to be armor and for weapons, but we can make something like this as a shielding against cosmic radiation with little to none weakspots cus any type of outside apparatus can be slapped to the body itself with no need of wiring, additional holes.

[@Ninth_Penumbra]

This type of deflector shield would also be a detector array, constantly monitoring the interaction between the generated electrostatic energy & the energy of the incoming particles. Perhaps even being able to do things like monitor what direction they're coming from & what parts of the spacecraft would need the most power to the shields. Is there any way that they could use the energy from the incoming particles to both run the system & modulate the power needed to run it. That way, more energetic (higher electron volt) particles would both see a velocity reducing drain as they interacted with the shielding & the intensity of the shield would autonomously adapt to the higher/lower energy levels of the incoming particles in a synergistic way (saving both power needs & wear on the shielding). Could an augmentive effect to the electrostatic shielding be achieved by cycling the strength of bands of shielding in a sequence (I don't recall the specific name for this kind of effect) to create a dynamically flowing shield (rippling down along the spacecraft, or at least away from a center point where the most emissions would be coming from), rather than a fixed one. You could visualise it like how air moves around a supersonic aircraft as it passes the speed of sound. Rather than incoming particles being deflected just a bit, the effect would be cumulative, with particles being deflected a bit, then a bit more, then more, then more - almost dragging the particles around the entire spacecraft before letting them go.

[@H4hT53]

I wonder if the recent break-throughs concerning virtual magnetic fields generated by meta-materials will play into this development down the line.

[@freehat2722]

5:37 MeV and MV are two different animals. Mega electron Volts is a measure of power and mega-volts is half of the equation to determine power. Where are the amps or whatever?

[@lafeechloe6998]

He used the righ terms...

[@mickoz84]

I have a question about the deflector grid array mentioned at the end. From the graphics and animation it looks like the particles are deflected around the the grid. But would this not result only in an smaller affected area but a similar dose where some areas have no radiation and others higher?

[@russellmitchell9438]

A matrix with electric charge over a dielectric region. Their cage-like models demonstrate the principle, but have gaps in the protection. Their solution was to add an additional offset layer. I would instead work with the scale; at the lower limit, they're describing a capacitor. Incorporate electrodes in the lamination of the hull. If it needs a more complicated structure, treat it as a metamaterial problem.

[@AishaShaw-cl6wc]

Good video.🌸🌸🌸

[@richardstarkey71]

The most hypothetically phieasable mode would look like Alpha at CERN as it could in theory turn the subatomic particle into energy, namely X-ray energy, upon contact and annihilation.

[@markwiegard8384]

It sounds like the deflector shield answer is to use the protons/capture them to generate enough power to deflect there effects. The shield would be like a solar panel except directing the proton into a multi reflector condensing the protons in a circular array or to a point to create a high voltage current that would be used to create a large magnetic field. Hence using a portion of the protons to refract the other protons. Potentially, you could use a parabolic curve design to focus the protons to a focal point on a carbon rod. What with and how to direct that much energy to charge a Tesla coil to handle 200megavolts and store some of it too would be the challenge. The point is how to maintain enough energy on a space station to hold a force field. If you had to lift that much energy storage and coil into space it would be impossible. Finding a way to use the environmental energy and leverage it against itself would be the answer. It would be an unlimited defense against proton radiation. For every action there is an opposite reaction. Next to flying a kite with wire and a key I’m already over my head. That’s all I got 🤷‍♂️

[@JohnWeland]

I wonder if this could be used in conjunction with a method of capturing (some) of the energy of those high speed particles to recoup some energy

[@lbochtler]

meanwhile ernst brüche, tektronix and basically every CRT based oscilloscope has used electrostatic deflection the math behind hit is well understod. the ability to deflect beams of high energy with low potential fields has also been known about and used for well over 100 years now. The only novel thing i have seen is the idea to create an electrostatic lens array that reduces the total radiant power at a large distance.
