I got LK-99 problems, but resistance is not one of them
Have my LIKE sir and my 1st born
Ain't one*
Nice.
So is anyone else back here after the recent paper about scientists creating room temperature superconductors (albeit at extremely high pressures)?
I am! Also a radiative cooling paint that’s colder than room temp
It has actually been known for a long time that under high pressure, pure hydrogen becomes a high temperature superconductor. This is just the first time anyone actually did it. Though they used a mixture of methane and hydrogen sulfide instead of pure hydrogen - basically swamp gas. But it's not useful. Consider this - they don't even use the kind that uses liquid nitrogen in MRI machines, they use the kind that uses liquid helium, simply because it's too much of an inconvenience dealing with the brittle ceramics that superconduct in liquid nitrogen, so they use the much more expensive liquid helium just for THAT. Consider that liquid helium is 50 times more expensive than liquid nitrogen, so if they're not even willing to deal with the relatively minor inconvenience of using the hard to shape and brittle ceramics to save 50 bucks, do you really think they're going to use materials that need to be put under 3 million atmospheres of pressure, in order to save 51 bucks?
@ThisGuyOverHere I am. I just watched another video about that breakthrough, and YT offered me this video right after it.

I am here for room temperature and pressure lol
"There will be no resistance to the widespread adoption of superconductors"
I see what you did there...
Resistance is futile
That was a really good pun!
Haha smooth
I had hoped that one would be too "cool" to resist.
Electrical puns are as easy as PIE.
Watching this a few days after the Korean Room Temperature Superconductor study came out. Crazy times we live in!
Lk-99 isn’t a room temperature conductor.🤷
I like how when you sort by new there are no comments for 10 months until LK-99 new dropped. What's funny is it was recommended to me.
Was recommended to me too.
Makes sense actually.
Kinda exciting that - if stars aligned - we might see one of sci-fi materials making its way into ordinary reality.
What's next? Thermoelectric converters with good efficiency?=)
Watching this now that a room temperature superconductor has apparently been created makes me super excited for what's to come. Hopefully it doesn't turn out to be a hoax.
It's looking like we have a green light! Papers are coming though the works! Although defects ect have to be figured out. But hey it's looking like our life time kind of stuff
Uwu so rare to found on youtube
@@hoangvuificationOwo let's wish for the best UwU
Don't wanna sound like doomer, but this kind of technology will take decades to implement, so don't get too excited.
@@hatman3445 ww3 noticing you're not a complete doomer yet:
Who else is here becusae of LK-99

yup, time for a refresher
TH-cam algo doing its thing lol
One of the "coolest" things you could do with high-temp superconductors is that you could build a global magnetic field around Mars. Once you have a global magnetic field, you can lower radiation levels and increase atmosphere retention time. Mars would be MUCH easier to colonize with a magnetic field.
I still don't understand why you would want to colonize it. I'd much rather build orbitals out of its moons.
Evito Cruor I don’t know why you wouldn’t when you haven’t even searched the Martian soil for any artifacts or resources that could surpass oil and nuclear energy and it’s the closest we have to earth
@@andreiharkov5110 Nearly every valuable Resource is more accessible in Asteroids and Moons. Most heavy elements have sunken into the core of planets.
This will not be different on Mars, even if we havn't done a lot of prospecting.
There is a lot of cool manufacturing techniques and research that you can do in zero gravity, but not on Mars.
If you are looking for opportunities for mankind, that are not accessible on earth, it's not a good idea to colonize a nearly identical planet but without atmosphere or magnetic field.
For new breakthroughs better go to titan, the upper atmosphere of venus or even good old lunar.
Acidos you are not a scientist nor have you found any brand new resource nor have you been to mars and checked under neither the planet
Acidos that’s your inferior opinion similar to the people who thought people should have stayed in their respective countries thinking it was a bad idea to explore and find the opportunities beyond the shore line
To do list this week:
-invent nuclear fusion machine
-create warm superconductor
-chill
absolute chill
-Only a hundred billion degrees
-Has warm in name, but is 35 kelvin
If you can separate all the neutrons and nucleons of a heavy (high-Z) atom, you can get far more energy than the standard radionuclide decay chain. It takes a lot of energy input, and has a relatively low total output power (using modern accelerators and non-specific materials selection) versus piling a bunch of dangerous rocks in tubes until they heat up.
Lanthanum Decahydride (LaH10) at extreme pressure (~170GPa, or 1,700,000 bar) is a type 3 superconductor at ~250-260 degrees Kelvin, -13.15 degrees Celsius, or 8.3 degrees Fahrenheit. Educated speculations assume that Lanthanum, Yittrium, or Calcium Hydrides may be able to achieve superconductivity at up to 320 degrees Kelvin, or ~116 degrees Fahrenheit at extreme (around 1 million atmospheres again) pressure. Other promising combinations are Cerium Superhydrides, Palladium Superhydrides, Thorium Superhydrides, Uranium Superhydrides, Metal Boro or Carbo-Hydrides, and other "hydrogen clathrate structures". The working theory is that the atoms are so tightly packed that any vibrations due to heat do not cause large lattice movements, thus providing stable tubes for paired up electrons to travel through.
High temperature superconductors may be a good candidate for high efficiency electro-reactor designs, or as a replacement for any materials that emit, absorb, or transfer electrons via pressure or impulse. Right now we cannot maintain these near-room-temperature SC materials because they exceed the compression strength of even diamond anvils at ~100GPa.

I'm sure this video will get a lot more traffic over the next few weeks
I’m surprised you didn’t make a community tab post with this video linked since LK-99 is **maybe** a thing
I imagine you're going to update us about a certain development in Korea...
11:12 is when he actually starts talking about what to use them for
cheers bud
Thanks
LK-99 I want to believe
This video will have an influx of LK-99 enjoyers.
Who else is here with me on the hype train?
Yup!
This aged well LK99 please be real
Looks like room temperature super conductors might actually be here now.
Nope, not yet

Watching on the off-chance that #LK99 is more than a fool's hopium...

I went back and watched 99% of the channel as I worked on a novel. A lot of the science that Isaac talked about shaped the world as to what they could and couldn't do. Long term sleeper ship, O'Neil cylinders, hydroponics, and many others that I tapped into formed the base to make it sound real. Thank you for all the hard work you and your team have put into it.
Just a slight clarification for the other viewers: a superconductor does not need to have current flowing through it to produce a magnetic field. In the presence of another magnet, the superconductor produces an (almost) equal and opposite field (Meissner effect).
The Meissner effect is the origin of the levitation so often demonstrated in videos.
Doesn't the other magnet induce a current in the superconducter that then produces the opposite field? Still, no current needs to be supplied externally.
@@AreUKiddingMeTV Oh, this get's complicated rather quickly. In reverse order, there are several different types of SC and one of them (Type II SCs) will allow the field to pass through it in little channels if you really force it close to the magnet, but in doing so, the SC gets pinned above the magnet.
The field does get excluded, but this isn't the same as, saying water is excluded from a waterproof coat. The outside magnetic field causes electrons in the SC to circulate and produce a magnetic field of the same strength but in the opposite direction. The two fields add up to a field of zero inside the SC - they cancel out. As is typical of physics, saying that something is zero isn't the same as the as saying it isn't there. Note that *both* the pinning and the repulsion can happen at the same time.
As for the mobius strip, I would guess that they used a Type II, as they are easier to come by, or a Type I and pushed it horizontally really hard to let "centrifugal force" keep it on track. Actually, the first one is the most probable.
PS, please do not call us eggheads. We don't like it, and it's factually incorrect as my head is the normal shape for a human.🙂
Please be true! 2023 Korean team!
Apparently people involved in LK 99 are racing to get credit, which is a green flag.
They struck fool's gold.
I truly hope we someday get to live in these incredible potential futures you map out for us.
We live in an incredible future right now. I’m 55 and compared to the technology of my childhood, we live in age of miracles.
I hope I'll be able to celebrate IA's 250th birthday with him in earth orbit one day.
Its called Warhammer 40k. Noone wants to live there.
@@justarandomname420
...wot.
I hate to be a killjoy but with regards to Room Temperature Superconductors we are far away as the record holder from 2019 Lanthanum decahydride may have a transition temperature of 250K but unfortunately that is only at 150 GPa Issac kinda dropped the ball there with false hope there are interesting superconductors which might see practical use but that is probably not one of them. On the other hand if we can just get space based manufacturing there is so much we could accomplish.
Though Nothing compared to what evidence based policies with independent oversight would accomplish on Earth since the reason we can't have nice things comes mostly down to a cocktail of corruption, inefficient and wasteful methods, bureaucracy, half done efforts, cognitive biases and gross incompetence/laziness. I think this is the reason so many technologies remain in the experimental phase because they aren't yet "idiot proof". >_<
Sorry about my pessimism but While there are things to be hopeful for I think we need to acknowledge the challenges as well
LK-99 better be real
Hey Arthur 2 years in the future. Scientist just claimed they had achieved room temperature conductors 27c. And so far things seem to checkout. gonna watch this now.
Nope 👎
Haven’t seen this video yet but today seems like a good time to
Its lovely to see all the new comments here after LK-99
Today, 26 of july 2023, a paper by south korean researchers has found a way to make a superconductor with room temperature and pressure. Its has not been peer reviewed yet, but it looks legit.
Better than room temperature, up to 127C (261F).
The most important thing of this paper is that the method is extremally simple and easy to replicate, materials are dirt cheap, so in a few weeks we will know if it really works. I went back to this video because of this study. For anyone interested, the candidate for RTS is called LK-99.
@@damiangoryl9302 Very excited about this! Just waiting to see if it can be replicated!
Oh boy can't wait for black mirror type tech
It was not, in fact, legit.
I've watched them all Isaac. Though I wasn't around for the first, I have been watching for years.
2 years ahead of his time, good futurism that.
I've been watching since early 2018. I'm pretty sure I've seen everything except for the live sessions. I definitely remember when you used to have to warn people about your speech impediment using Elmer Fudd and how impressed I was that you overcame that issue so completely. I've had an awesome time on this channel and I look forward to the new content. Keep it up, Isaac!

BROS WE'RE SO BACK!
WERE BARRACK
It is very easy to become jaded/cynical when bombarded by the negative news stream, but these always make me feel a bit more hopeful for our future.
You always make it sound like we are one breakthrough away from interstellar travel and I love it. I hope it happens in my lifetime.
:) Probably not 1, though it would depend on what the 1 was, but I do think we're close to the needed tipping point that will make space travel vastly easier
We would have, but certain groups of people won't allow us to have any fun.
If we have a breakthrough in life extension you may live for centuries and perhaps even long enough to see interstellar travel.
Ro Jaws any breakthroughs will be fairly expensive at first
@@isaacarthurSFIA YT brought me here after watching this video about a superconductor breakthrough. th-cam.com/video/kM7J56OxA6w/w-d-xo.html
As to the cost of cooling long-distance superconductive transmission lines, I read (in an old book about electric vehicles) that lots of air gets liquefied to extract from it oxygen, some of the nitrogen, and other valuable gases, but then most of the nitrogen just gets released back into the air because there's no market for it. That's a waste of a lot of electric compressor power, which might be better used if we had a continuous demand for LN to keep the power lines' chilling sleeves topped off. Because of course, it's not enough to just have SC lines, we also have to ideally replace thousands of miles of unsightly tower-lofted lines with underground lines. I mean, what if an overhead power line cooling sleeve sprung a leak, and Bambi and Thumper happened to be frolicking about under that line? 😄
Issaic arther: releases this video
Scientists 1 month later: hold my beer
Congrats for reaching 250 episodes.
20:16 looking forward to our collaboration !
I hope perseverance finds alien life soon.
Is it alien life though, if we happen to be related?
Sorry dude but we will always be on the cusp of finding life for the rest of our lives and it will not happen.
@@avanconia You have a reason for that claim or you just like pessimism?
@@benbaselet2026 The fact that we won't find it is just as interesting as finding it could be. I won't insult anybody by qualifying basic math.
@@benbaselet2026 watch the fermi paradox vids hes not saying there are no aliens just that we probably wont encounter much more than bacteria
A question.
I am curious if you, Isaac Arthur, would consider doing a video about "ion lifters" and how they work.
I was reading this blog post: infomashup.com/mashups/Who-Made-the-Triangle-UFOs?tID=rzvp2n5li8z
And I am curious what, from the perspective of exotic physics ( pardon the term ), is going on here?
Maybe, seems an interesting topic
If I recall correctly, this is an electric wind thruster and the explanation is that when air molecules hit one of the electrodes the voltage is so high that the particles are ionised, and since the particles are now electrically charged they are pushed towards the opposite electrode by the electric field between the electrodes. As the ionised particles travel from one electrode to the other, they collide with neutral particles in the air, accelerating it and producing a reaction force on the thruster. Then the particles hit the other electrode and most of them are neutralised, however there will still be some ionised byproducts such as ozone. You can think of it like an electric propeller except the propeller blades are separate air molecules moving through a magnetic field. These thrusters do not work in a vacuum because there is no working fluid to ionise. Also, a group of researchers at the MIT has recently built the first self-contained aircraft using this type of thruster.
@@isaacarthurSFIA You can also use high voltages to charge the leading edge of aerofoils positively or negatively, while hiding an oppositely charged plate under the trailing edge of the top wing surface, in order to keep the boundary layer air stuck to the lifting body without separating. It is similar to vortex generators, but has less drag, and can work on longer chords, like some military flying wing designs to lower stall speed. Some companies like Plasma Stream, have products you can put on semi-trucks to help optimize turbulent areas of airflow which cause induced drag and pressure drag.
Using it as propulsion, by ionizing some of the particles in the air and attracting it rearwards is generally not efficient due to energy dissipation and breakdown potentials.

I discovered Issac about a months ago, and am almost caught up with all the videos! This is by far the best channel on YT.
I only found your channel in 2017, but I went back through your whole library and can say that I am proud to be among those who have seen every single episode. You are a legend, Isaac, and it has been a real privilege.
This month scientists discover a superconductor that could work at 15 degree Celsius.
But the material need to be under 15 mil psi of pressure
That still an amazing achievement, comrade, that the ability to produce a superconductor above c it itself significantly impressive. Hopefully we discover a material that doesn't need such a high pressure.
Issac, you’re the best. Thank you. Thank you for giving me hope for the future. Your community loves you. You deserve it.
Thank you. Got chills when you started talking about multi-kilometer-tall buildings.
LK-99 gang rise up
Congratulations on reaching 250 weekly episodes! I've always liked the thumbnails you used for the episodes, any plans on making some of them or make new ones solemnly for merch?
I would like to note that I have watched every single episode up to this one so far, and in upload order no less. Keep up the amazing work Isaac!
Congratulations on the milestone! Thanks for every single episode:)
here after LK-99
Not sure if I found the channel in 2015 or 2016, but when I did, I binged everything that at least had not been the older version of a remake and I have been here ever since and to my knowledge have watched every regular and bonus episode. Not much for livestreams though, only watched the first few of those. Love the channel and I do not plan on leaving any time soon
I’m here only since 2017, but back then I’ve watched all the previous episodes and I suppose almost all of the current ones since then. Thank you, Isaac, for all the inspiring thoughts and a great time.
One of my favorite channels. Thank you Isacc Arthur. So much to wrap my brain around. Congratulations on your milestone.
LK-99 🙌🏻🙌🏻🙌🏻
Issac, I saw your videos three years ago and was fascinated . You have opened my mind so much. Recommending so many incredible sci fi stories and explaining so many awesome concepts and principles. You have opened my mind sir. Thank you
250 oh boy ..
i remember very well the super scatchy graphics of the early upwards bound EPs .. (still my absolute favorite outro music)
happy it worked out so well for you, keep the good stuff coming!
I have pretty much watched every single episode at this point.
MUCH LOVE.
THANK YOU FOR YOUR AMAZING DEDICATION TO THIS.
Isaac, I want to ask for your advice.
I'm in my 30s working a job that's unfulfilling but pays well enough to support my family. But all my life I never knew what I wanted to do as a career.
But watching your videos over the last few months is making me yearn for a future where humanity can operate in space, and I wish we didn't stop the progress we made during the space race as we could've had decades worth of technological advancement compared to today.
I want to help put humanity on the moon, having industry, mining, and manufacturing outside of Earth. How can I help make that happen? What should I go back to school for, and what line of work can go towards such a goal outside of working for Space X? Physics, engineering?
Put as much money aside as possible and google what kind of maths you would need to learn, then start teaching yourself that maths in your spare time. After a year, you'll have tons stashed away and know most of the maths already.
No need to go back to school! Spacex doesn't worry about degrees, they care about competency!
How about learning about economics, it is the real limiting factor for industrializing space. If an activity isn’t profitable it won’t persist for long periods of time.
I say that you should spend your extra time/money/energy/etc. with your family. It may be too late for you but it definitely isn't too late for your children.
Now that LK99 is a thing and seems to mostly function at 70 degrees Fahrenheit as a superconductor, are you convinced we finally have a material that can potentially help produce super constructions as mentioned in this video or would we need just a little more thermal wiggle room to achieve the best results?
No because ot has the material property of a brick you can't make wires out of it no flying trains or cars sorry.
And combine what WokeandProud said with the fact it also isn't superconducting.
Dude can I just say how great your videos are, I love learning more than anything I try to soak up as much knowledge as I can, these videos are absolutely fantastic I'm able to have to have a basic grasp on complex topics. I'd give anything to have a teacher like yourself I'm just thankful I have your content here and I look forward to more :)
Just want to say congrats on hitting the 250 mark! I remember way back when I first found your vids, you would use an image of Elmur Fudd with an apology for your speech impediment and asking folks to use subtitles at the beginning of every video. Been a while since I saw that, you've come so far with your speech that I can barely hear it now. Here's to another 250, cheers! 🍻
You are a class act.
i just want to say Isaac that in these bullsh*t times we find ourselves today, your futurism videos give me hope and inspiration

I have watched every episode on your channel. When I found it 2/3 years ago I went back to the beginning!
Where did that 50% of electricity lost in transmission number come from? This source puts it at 6 to 10 % insideenergy.org/2015/11/06/lost-in-transmission-how-much-electricity-disappears-between-a-power-plant-and-your-plug/
(In the USA grid)
Yeah, it does seem incredibly High to me. If that was the case you would think power lines would be catching on fire all the time.
You beat me to this. Good for you for calling out misinformation.
I'm going to throw in a few lessons from my electrical engineering classes here to explain why loses are so low. Because it takes engineering to get the losses that low.
Transformers (you've probably seen them as those big bulky things on power line poles with what kind of looks like two stubby antennas (they aren't antennas btw)) are a great way to reduce wasted energy. From a linear element perspective (meaning this is a bit of a simplification), transformers change the apparent resistance. Increasing the voltage drops the apparent resistance. Stepping the voltage back down increases the resistance again. This is why they up the voltage leaving power plants and then step it back down closer to residential centers, so your appliances actually use the electricity. Modern transformers can be 95% to 98.5% efficient.
However resistance isn't the only thing that saps power. You lose power in power lines primarily to two reasons: resistance and inductance. Super conductors removes almost all resistance (I think they still have something like 1e-35 ohms of resistance, double check that though). Inductance refers to the creation of magnetic fields from running current. With direct current (DC) like current from typical batteries, the current flows consistently. It will just build up a small magnetic field (e.g., wrap a wire around a nail to build an electric magnet), and stop losing more energy to the magnetic field once it has built up. However alternating current (AC), which is used in most power grids, causes the current to change direction. Because it constantly changes direction, the magnetic fields constantly changes direction, leaking power constantly. This isn't a lot of wasted power, but it adds up over long distances.
To reduce energy lost to inductance, European cross-country power grids have been adopting high voltage DC power transmission lines. Please forgive me if I get any of the details wrong I'm not a European. This is a little more complicated as you cannot scale voltage using transformers on DC power directly. But it basically works by generating power either as AC or converting it to AC -> use a transformer to up it's voltage (reduce apparent resistance of down stream elements) -> convert to DC (using e.g., a rectifier, diodes, and capacitors) -> transmit long distances -> convert back to AC (with what is called a power inverter) -> transform the voltage back down (so appliances can use the power) -> deliver to your home/work/school/etc. Most of the losses in efficiency are from all of these conversations, not transmission anymore.
Edit: added the name of the element that changes DC power to AC power. Included a few other details.
The number would be quite high if you would wanted to transport electricity between continents e.g. from places near the equator (solar energy) to place further from the equator where most people live. Your numbers are lower because in the US the energy companies try to avoid long-distance transportation at the cost of less-ideal energy generation.
Michael V A more condensed version of this would reach more people. Presentation skills matter (especially for engineers).
Or also the EIA directly: www.eia.gov/tools/faqs/faq.php?id=105&t=3
I would love to see ION drives equipped with super conductors? Imagine, being able to shoot gas out of an engine, and the speed at which you are firing that gas, is only limited to how much energy you can collect. With large enough solar panels and batteries, you could throw fairly heavy atoms of Argon/Xenon at speeds nearing the speed of light. At those kinds of energies, single atoms of gas would produce levels of thrusts that could be measured. A fairly small amount of gas would let you get to some amazing speeds!
Imagine firing an Ion drive space ship from a rail launcher, then part way through, the drive is turned on, slowing it down, so it can reach a planet, moon, or asteroid. It would save on gas, it woulds save on the time needed to speed up the ship up to cursing speed, we could charge the batteries before the launch, and just use the gas for slowing down, or Slowing down, and a return flight back to base!
The possibilities!
If you have superconductors you can also probably do fusion rockets instead of ion drives.
Pretty sure those are the fusion powered ion drives in the show Expanse
@@Azilythe Along with a bit of handwavium magic.
Ya can never go faster than the shit you're spewing lad. If that's near light speed that's all shes got.

Isaac Arthur is a god send. A high level explanation of fascinating material and practical applications. I’m sure all of us here are curious intelligent minds and doing our own research sometimes is just exhausting. So nice to be able to watch Isaac and get trustworthy scientific facts
Room temp super conductors = fusion
Like seriously fusion reaction rate goes up linearly with temperature and area of the inner reactor, by increases by the power of 4 of the magnetic field strength so double the field strength. Double your field strength and you get 16 times the power, and room temperature super conductors means you can pump a lot of power into them before you lose super conductivity.
Congrats on 250 i cant wait for the next 250. One bright side to my job is being encouraged to use headphones in a factory atmosphere. So I have 10hrs a day to fill with podcasts and audiobooks. Being from Dayton area this channel was a godsend. For the entertainment value and helping to support a fellow Ohioan. Keep up the good work man and stay safe out there :)
Good old Dayton, other corner of the state but I was a research intern at Wright-Patt AFB back in 2000
Best episode in months and I think there is even more to learn by diving deeper.
Been a loyal viewer since I found the channel in 2016. Keep up the great work Isaac.
"... no resistance to the widespread adoption of superconductors"
I see what you did there
Terrible terrible terrible pun!
Love it!
@@Sega22245 No because super conductors have R = 0.
He actually said "no wesistance to the widespwead adoption of superconductows"
@@Sega22245 shit I accidentally left that hard R in
Resistance is futile.
Who is here post LK-99?
Aye. I am. This seems like the real deal this time and I can't wait until it's confirmed... or not.
Me, I can't wait to see the reproductions of the experiment. it could help a ton in better understanding photosynthesis.
i hope it's real. we'll know soon...
Yep fingers crossed let's not get too excited for now. There's a lot of skepticism in the scientific community thus far.
@@bornkinggamer3347
Too late. I already went through my excitement phase. Now no matter if it's repeatable or not will get a meh response from me.
I've been watching for years, it is always interesting to hear your thoughts
Ooh, this is typical now!
Very exciting!
Congratulations on the 250 episodes. I cant say I have been here since the very beginning but if memory serves I subscribed around 8k subs. I have watched every single weekly episode and the bonus ones but I rarely watch the livestream. Actually I have watched most of the older episodes at least twice especialy the mega structure series. Keep up the good work Isaac you fuel our imaginations.
This isn't looking so futuristic these days
Thank you Isaac for your excellent content. Considering the topic of this video and current claims publicised on the creation of room temparature superconductor material. Are you inclined to look into that research that is yet to recieve independent research verification, or prefer to hold back until such time?
Great work, Isaac!
"There should be NO RESISTANCE..."
I love you, Arthur!! :D
@Issac Arthur - they just announced a room temp (15C) SC! Maybe that'll make a good follow up episode to this one :)
your videos literally help me with my depression, thanks isaac.
Well, you are the best and bring'n this information to us, and my fellow brains (smart contacts) love it. Although, you just drop a broad amount of information in our lap, and it's really hard to apply it to life or projects.
Oh how relevant this video is currently, algorithm knows what's up.😊
Where are you getting the 50% power losses to transmission lines from? The sources I’ve seen list the loss as between 5% & 15%, depending on the system in question.
It's not just the big transmission lines, it's the smaller distribution ones, the transformers, the switches, and all the hardware between the power stations and the users.
@@francoislacombe9071 wait , would superconductor make AC obsolete ?
@@davidegaruti2582 Probably. And don't quote me on that, but I think AC doesn't work well in superconductors.
Yeah, the general efficiency of the power grid is usually estimated to be around 90% from generator to user.
Maybe if we factor in the theoretical losses from energy storage (or lack thereof) for renewables it's less. That could be eliminated with superconductors and good global coordination.
@you'll have a stroke reading this
well, pairing a superconductor with AC should work just fine, just not as well as DC because the current at which the superconductor stops superconducting is lower IIRC but it is simply not the smartest move. AC radiates power away (because of the changing magnetic field) and is very complicated.
The complicated part is that even at low frequencies like 50Hz electric field waves bounce back from cable ends. So that means if you have the exact right cable length the waves will cancel out (giving the generator an effective short) or at another length they will add up (double the voltage, destroys consumers) and the voltage can vary from point to point as it's possible to have a "standing wave"... The power grid is rather hard to run because of that. DC is really easy in comparison.
@@zamundaaa776 so pretty much every existing alternator would have to be converted into a dynamo/attacched to AC/DC converter in order to supply this power supercunductive power grid ?
Seen every episode? Definitive not... yet =) but till now I didn't regret any episode, always something to learn or to think about. Great work!
Is there a option within TH-cam to check since when I am subscribed to a channel?
Really interesting going back and watching this after the LK-99 paper came out.
Its been replicated and confirmed by multiple labs
Love it. Thank you for what you do
