Hi, today I will tell you about red mud and how it caused a disaster. - Věda a technologie
I don't care about your accent being weird, bring it back
Read some more comments, it seems everyone agrees with me. Also I want to comment on your Brilliant ad that it's just a confirmation of what I've always said, Chemistry is a branch of physics, biology is a brach of chemistry and they're all branches of maths
yea this threw me off for a sec ,
i was like is another video playing in the backround or my audio no in sync,
wait he sounds different ?!?
I miss your accent - it was captivating. I have learned that I like everyone's accent no matter where they are from. Except mine of course... I have no accent (according to me at least).
@@cosworth6nut yea it just isnt the same, his voice had a charm to it
First thing I did was looking for a button to change the audio language
Bring the Estonian voice back!! ❤
How about discussions on the science here rather than whining about how its presented. These comments about the voice are ruining the comments for everyone else. Dont like? dont watch.
@@uraniumcranium2613 It was the human touch of hearing the voice of the man behind these videos that made them popular. Without that human connection, these videos are no different than the clickbait videos mass produced using synthesized voices or AI. If you don't understand the importance of having this human element in the content of this channel, then it is you who are ruining the comments and the presentation. He got to be popular because of his voice and popularity. We simply ask to have what we fell in love with the channel return. The science is better when it comes from the voice and likeness of the content creator.
@@notsofastener indeed, the story itself is not unique, but the voice was. It was not only accent, it was also the emotion in the voice. Enough reason to try to get back the human
yes :)
@@uraniumcranium2613 your comment is ruining it for me.. ;)
There seems to be a common theme here. We are all respectfully requesting your original voice track. 😊
Thats was his mates voice btw. He couldnt shprekitty ze lingitty very well though and got shit for it. These were early Thoisoi 1 days way back wen though. So this is voice number 3.
yeah, this voice takes away the charm the channel once had.
@@pauls5745
I agree.
@@pauls5745 I assume that when you say "charm", you mean the "so incomprehensibly thick accent that for the longest time, his channel lived on my "Don't recommend anything from this channel" list"? Don't get me wrong - The tiny amount I could actually understand of his earlier vids seemed to indicate he had good content, but it's pretty well worthless when the audio is so butchered by his accent that he might as well have been speaking Klingon.
Agreed!! 😢
Bring back the Thoisoi voice. We like it.
From Edinburgh Scotland with respect.
It is very old video, after his lab is burn down there is no new video on this channel. It is atleast 3-4 months old video
From Fife, Scotland, please bring back the old voice
@@hardikyadav5277 : is it. Looks new to me. He looks older. He was younger before. I mean i had Thoisoi 1 though
@@GraemeWight-wx3xz I mean this video is recorded at least 5-6 months ago, in January 2024 his lab burn down during a Chemical experiment. It is recorded before that incident, you see all of his videos on his channel are not new they are 6-7 months older. He uploaded a video on his channel about documenting his burn down laboratory. The chemical experiment is so dangerous that he have to call fire prevention team for it. I hope you understand this
@@hardikyadav5277 : ah. I see. I have not watched regularly for some so am behind a bit.
We all want your voice back. You could have chosen a better voice like English but we like your voice. Honestly I love your channel but I find it hard to listen to that voice over 💚💛❤️
"like english" me when i lie
@@verticalpug2026 please explain what you mean. I don't get it
@@rastaralph7154 social justice warrior like him are everywhere.. they love make people feel bad..
No we don't. I prefer to understand what he wants to say.
I agree with everyone else.... we want the original Thoisoi voice back! We have all grown to love that voice. Don't ever change for anyone. Be yourself.
Hi everyone! Please return your normal voice. I understand that it might be a lot less time consuming to have someone else do the voiceover, but it clearly results in barely anyone being interested in the video anymore. This is mostly because your accent is part of the charm that made the channel interesting.
hell no.. finaly i can watch those videos.. it was unbearable..
No, I prefer to understand what he wants to say. Watch the old videos with repeat, if you just like to hear his voice.
No no no bring back Thoisoi's voice. If people cant understand that beautiful Estonian accent that is their own fault, not yours or ours.
Bring the Russian voice back!!!
Agree.
The khello everyone is a watermark for this channel
Hello ewerybudday
Where is my Comrade?

Bring back old voice of yours we miss it 😢
Maxim, to us the familiar warmth of your voice is as important as the quality of your video. It's the "element" of your periodic videos that cannot be isolated and discarded. We miss you.
warmth is a great way to put it
@@captininsanoo00 Our voices are a considerable investment into our public persona, in this case he could never "trade up" to a better voice. His own is perfect and I like to think he just misplaced it somewhere.😂
As just one of the many fans of your old voice, I'm worried. Have you been injured or something?
Bring back the Thoisoi voice!!
I agree with everyone that your old voice made this channel
Bring back the original Thoisoi voice!
This video makes me think about the red sludge lagoon in Puerto Ordaz, Estado Bolívar Venezuela.
Those places need to be roofed with Glas-roofs, so the mud can dry in the sun! Preferably baked to pellets or dry cobbs.
North American native English speaker here. Been watching your videos for years, I started with your crystal growing videos. I understand why you might have gone with the voice over, but it lacks your genuine enthusiasm and spirit. Hearing your dry wit through tone of speech was one of the fun aspects of your videos. Love all your videos, I've learned so much. Thank you!
You sound so much better and more authentic with the accent. We want Thoisoi back!
Scandium was extracted by soviets and used in Mig-21 and Mig-29 as they haw all Aluminium construction.
In orders under 1% it gives small grain high strenght alloy.
When welded Mig-29 construction (whole center body was both fuell tank and main construction element) was heat treated to obtain maximal strenght.
Holy crap, someone actually not whining.
I hope all the waste around the world gets treated. No waste, only recycled materials worth money. When we take stuff from the ground it's often better not to put it back, so use everything.
tbh non original voice is kinda of disaster.. but i still like ur video.. i love listen to your original voice ngl it quite immersive..
The vooooiiiicccceeeeeee🤬🤬🤬🤬🤬🤬🤬
From a stoic Eastern European accent to a smarmy American real estate agent accent is a disaster.
it blows my mind that I never heard about that accident in Hungary, which is very weird since I live in Slovakia. What a disaster, those poor people. I hope people responsible for this were punished. However, since we're talking about Central/Eastern Europe, I seriously doubt so.
en.wikipedia.org/wiki/Ajka_alumina_plant_accident
Surprisingly, given that roughly 40 km2 were exposed, 'only' 10 people died. The sludge was like a huge and strong river. The owner of the factory was among the richest Hungarians of the time. I am not entirely sure but he likely wasn't imprisoned.
Even is something like this happened in America, I doubt the people responsible would be jailed. It seems to be a worldwide thing that they often get away with it.
@@bteebi after a long trial witch started maybe two times again for example due the judge went into pansion ( the usual temporization for 10 years ) they where acquitted, free to go, no punishment for 10 dead people and huge damage, the original designer engineer of the dams was the quilty but he is dead since the 1970' maybe, long ago before the accident
Bring your original voice back. Your English is grate and your voice made your videos unique. Please bring it back
I AGREE!!! I had no idea how many of us want your unfiltered accent back. Americans have always thought Slavic accents sound intelligent, especially Russian, knowledgeable, and many find it charming. It's like getting tickets to a live band and they play a DVD.
I agree with the others. Bring your voice back. You have an accent, but I can understand everything you say, and the accent makes the subject more fascinating.
Great video!
I love your channel a lot, but your voice and the charming accent is the soul of it and I subscribed for the entire package my friend :) I swear by my holy black mesa research facility mug, I won’t watch any videos without it.
Hey...we trade. 1 mil subs for the voice back ok?
The English voice makes it easier to concentrate on the chemistry being discussed, but the soundtrack needs to be more carefully edited. At 4:00, a crucial phrase is omitted: "Afterwards, it can be calcine to obtain alumina." Your command of English seems to be good enough to catch mistakes like this, that were obviously made in editing. If it is too late to re-record the soundtrack, you can put the missing words on the screen with an asterisk (*). Keep up the great work!
The AI voice actually made be stop watching (in less than 30sec)
and put this video in my: well i may watch this video later if it crosses my path again mode
Its a shame that they were to wasteful with all that captured metal!
I liked your voice so much better. Please don't hide yourself behind a voice over you are what makes your video's not a voice
Please bring back your original voice, we love it....
Rhenium was more
Expensive than all
Fine well and good, however, I remain curious as to what type and quantity of toxic waste is produced from all these possesses...
we miss the russian voice over 💔
i bet this guy just LOVES us. First poeple are, for years like " oh god could you change the voice, its very weird" and then , finally he goes " ok you know what. fine FINE. ill do it" and hires a guy to do his voiceover, and we´re like " NOOOOO BRING THE OLD VOICE BACK
Yeap... He stated at one point he had no time to do both voice-overs, the original and the one in English. Hence the hired voice-over. But, people being people, they're never happy about anything.
Me? I'm here for the fascinating science.
@@The_Modeling_Underdog i enjoy the science but his voiceover had a charm and life to it that this just doesn't. When i first found his videos i struggled with the accent but loved the chemistry and his voice. Only took a few videos to adjust to the accent and it became an essential part of his videos. I have such a hard time getting into them with this new voice
Thank you for the nice explanation. Thank you for your effort and time !
Bauxite can smelted with frequency plasma.
Rare earth ores smelted with bauxite for thermitic reaction.
one of the only channels I watch every video any time I see them
Thanks a lot for your work ! You make one of the best chemistry vulgarisation program I’ve seen in the last 20 year
Bro, I felt this. I was diagnosed with cirrhosis last December. It is such a roller-coaster. FYI I thought you were 18-20 😂.. I hope you find your way through this. THANK YOU, you put a lot of what I'm going through into perspective. Even if you have cirrhosis, it's not the end of the world. So don't worry too much. Feel free to reach out if you have questions or just want to talk. Best of luck my friend.
Where is my boffin comrade? Give back his own voice please ;p
This is quite interesting. I have worked in alumina and Nickle refineries. Would be cool to see tailing reused and cleaned up.
The first process (adding carbon & heating) is IDENTICAL to iron blast furnace process.
This waste product recycling process is very interesting! The aluminum manufacturers should contribute to the development of such techniques even if it is not very profitable. Very interesting video. Best regards! (There are some comments about the voice and language in the video, It makes no difference to me,I can read translated text or listen to dubbing, whichever is better, easier for the author is ok for me.)
Yes, please bring The Man's voice back.
Question, Why can't this "red mud" be treated as an iron ore to get iron and the slag be processed for other, expensive metals? Just asking.
I love this idea of you discussing the topic of how chemistry is used to solve real world problem
And also bring back the Thosoi voice
we liked your original voice. the dub feels fake.
Great video. Thanks for all the hard work you put in to educate us.
Could not the red mud be processed in a blast furnace like regular iron ore to produce the steel? This is already using carbothermic reduction of the iron. Perhaps the other contaminants prevent it from being useful raw material?
Do what you are most comfortable with :) your videos are still beautifully shot, informative and fun to watch.
It's interesting to learn how so many useful elements and materials (i.e. iron oxide, TiO2, SiO2 and especially Sc2O3) can be extracted from Alumina processing waste which was once discarded as useless (and toxic) red sludge. I'm just amazed no one else in that industry ever tried that before!
And, I also agree with other comments about Thoisoi using his original Estonian-accernrted English voice again here as well!
(Also glad to see his tuxedo cat still appears at the end of his videos at least here!)
love the new voice over, thank you so much. I always loved your content.
Like everyone else is saying, I miss your accent too :( Bring back your natural flare! your unique dialect and way of articulation is one of the best things about your channel :D. don't be afraid to come back, my friend.
side note, amazing video. Another incredibly informative and entertaining form of educating us on cool topics, some awesome stuff thank you for the info!
Your natural voice is far superior to this synthetic one. Not only is it more pleasant to listen to, but to an Anglophone, northern and eastern european accents just seem *right* for any type of entertaining scientist
Ive been scrolling a bit, and I think he's scoring better on the algorithm because so many people are asking him to revert to his natural voice 🤣. His channel is doing better by using a narrator
The experiment is fine, but one major thing what you also highlighted regarding the disaster... The red mud should be dry. This is main challenge in industrial size, this is partly the reason why the store it... To make it dry.
So the method introduced as a solution, regardless it ignores root cause, the process what cause the disaster requires for the "solution" anyway :D
The voice being used to narrate isn't bad, and does a good job, but definitely love hearing YOUR voice.
I don’t see a good way of scaling up the process for the recovery of iron that would leave it cheap enough to compete against the influx of cheap metal in the market, or against the cost of mining raw material. Now, if you treated it like sulphur in the refining industry, where they incur the cost of extra steps just so someone else can carry away their waste product at a reduced price so they don’t have to deal with it, then it might work. It just lowers your profit on the expensive products that you extract downstream….
Interesting and informative!
I LOVE YOUR REAL VOICE AND ACCENT!! PLEASE BRING BACK THE ORIGINAL!! 🙂
Very interesting topic. I'll check if we have something about it in our university.
I thought the Hall-Héroult process used bauxite directly mixed with criolite (to lower fusion point). But it seem it requires alumina. The first part of the process you describe is the preprocessing with NaO2. Extracting aluminium from Al204 (alumina ) is an electrolytic process and very energy intensive. The way you describe makes it seem that is just to use high temperature (calcine). It is not: the electrolytic method produces high purity aluminium directly. Trying to use heat directly would require far higher temperatures and contaminate the aluminum.
A similar accident happened in Brazil but it was the red mud from iron production that is toxic but not corrosive. It destroyed an entire city and killed lots of people, not because of the toxicity that is lower, but because the huge size of the lake when the dam broke. The dams with red mud from alumina remain here waiting.
Love to see I'm not the only one that misses the original voice. 👍
Please bring the original voice back. I love it. It makes your videos more fun to watch.
Harvesting other people's waste is thank God becoming a big industry.
Another very interesting video! The two Russian metallurgists make a perfect double act. I can't believe they dropped a red hot crucible straight from the furnace into a bucket of liquid nitrogen! Chemistry is fun!
Expanding horizons has outsourced an operational impact opportunity with qualified returns.
Thanks comrade in any language you choose.
Electrowinning is often used on the molten aluminium salt. I wonder if reduction of the other metals can be achieved similarly. There is great potential for this processing to be interrupted, to be a controlled load to balance an electric grid. I recall seeing co-located solar generation in Australia.
Welcome back brother. Glad you overcame the fire fiasco.
Interesting, and hilarious. Scary spills, and ricochet at 13:00. I do like the voice, just adds to the wackiness.
My brother in Chemistry! I love your videos! keep up the good work!
Killer video. Keep it up. Thank you.
This is a very interesting video. But I missed the part where it explains how you get Iron, Titanium and Scandium from this red sludge in a practicaal, efficient and enviornmentally friendly way. Because the heat processes and chemicals it has to go through to get there seem like it costs about 1000 as much to extract these elements as what they are actually worth.
I'm wondering if, rather than immersion in liquid nitrogen for the initial tablet treatment, you could just allow it to air cool in an argon atmosphere. I also wonder if rather than a carbon mix with the red sludge tablets you could use silicon which I imagine might precipitate out more easily as silicon dioxide later. Perhaps computer chip makers could be partnered with to utilize cast off silicon from their manufacturing process? Just speculative thinking. I am hardly a materials scientist or chemical engineer.
I can't speak foro others but I love all the different accents. For me it is to language as spices are to food.
I would love to hear more about ore refinery and waste refinery for metals
Thank you fur the awesome videos!
Great video! ❤️ with or without your voice 😇
Similar environmental disasters happened in two cities in Brazil, in 2015 and again in 2018 (Mariana and Brumadinho, respectively), due to iron ore mining. Researching, I found out that something like that happened in Italy, in 1972! It's bound to happen again and again, because by-product production is expensive and the miners just don't care. It's much cheaper to bribe politicians than employ better methods (I know that, because I work at an environmental agency and decisions are made in "upper instances", against all our technical reports...)
Very good information 😃
Not that it matters but I live in Bauxite, Arkansas. A mega butt ton of aluminum owned by Reynolds was made here. They have since shut down here and we have massive deep bluehes here.
If it were cost effective to reduce red mud, the market would have been doing it already. This sort of ecological remediation needs to be government subsidized. At least while the prices of the constituent metals are low.
Why does everyone here love your original voice, I am also one of them.
Dude ! We love you! your voice and who u are, matters!
I appreciate your natural accent mate.
They're gonna need DAP for all that caustic.
Very interesting! Why the red mud after drying isn´t transformed with coke into iron at high temperatures like the normal iron ore ?
Agree with the other commenters, your voice is who you are! Bring it back!
One of The French crowns in the medieval period was aluminium.
Man I can't even read these comments anymore. Stop complaining about his voice already. Its HIS voice, his choice. Ffs if you can't deal with it then watch other youtubers. Above all leave the man alone and let him decide what voice to use!!!
Great informative video!
I hear the new voice. It has to be something I'm really interested to watch to stay
Excellent video bro!👍
I wonder if he sold the channel after his lab burned down?
Its an interesting process but I have doubts as to whether it can be profitably scaled up.
1 ton of steel in europe is something like 3000 euros
very interesting........ im sure one could have this red sludge transported cheaply around as its costly to not dispose of
ATTN: I'm starting to think the man was murdered (likely for one of his chemistry findings) and his channel is being kept alive by way of AI generated material/voice. I'm not even joking, his last video before the transition was about how his shop was burned down.... There's no other explanation??! Why doesn't he answer our pleas?? Either way, we all hate/struggle to enjoy this. I haven't made it entirely through a single video since you got the voice-dubber. But you've gotten a lot more subscribers since then so I guess I understand, and don't blame you for wanting to cash out. but it actually does make more sense that you're dead and that someone else is cashing out.
Bring back your natural accent we all like you for you! Sure there could be some word I have to listen very close to understand but that is what we like about you. I do not tell my foreign friends to get a translator so I can understand them no I just listen to them and learn how they speak. I used to have a strong German accent when I was a kid and I was made fun of and called a nazi relentlessly when I moved to the USA. My true friends appreciated my accent and helped me learn to speak English better. Be YOU please!
Good process it is usefull to humanity
Red mud processing looks stupidly energy intensive .
Go back to the original voice!! I really don't want to click on these vids anymore, but I gotta keep doing a voice-check in hopes the Russian voice is back. Sadly I'm gone without watching.
