Could you answer the complex political and economical reasons that hinder the use of thorium in an upcoming video?
They probably didn't use thorium for power stations because it requires entirety of it to be new R&D, which costs at least tens of billions of dollars, if not hundreds. With uranium, the R&D was already done for them because they are piggybacking off of the research done for military weaponry.
To use the so called "waste" for building bombs.
'Without exception, [thorium reactors] have never been commercially viable, nor do any of the intended new designs even remotely seem to be viable. Like all nuclear power production they rely on extensive taxpayer subsidies; the only difference is that with thorium and other breeder reactors these are of an order of magnitude greater, which is why no government has ever continued their funding.'
It would cost taxpayers money, you cant really justify buidling it when you already have something that does the job, the end.
Tantalizing.
Lovely presentation but you left me hanging Bud.
As a nuclear engineer you did a great job explaining nuclear fission. I am not sure how you got your weight for critical mass, as it has more to due with density and shape of the uranium, but thank you for another great video!
Disadvantages of thorium over uranium ?
probably assumed a sphere with a perfect reflector?
@@jaikumar848 thorium isnt fissile
They got 400kg because that's the smallest amount of fissile material needed for a sustained nuclear reaction in uranium. ~Wiki~
@@huntercasey1019 thats definitely not the smallest amount of fissile material needed...
but with a bare sphere with no moderator or reflector i would believe it
Fermi "rushing" to the lab is making me laugh too much. Love the vids!
I legit love your videos, so glad you guys decided to go full force with these simple explanations.
This is the video I've been waiting for!
These is the most detailed and easy to understand video about nuclear fission for the first timers.
Thank you so much for this insane video!
Lesics videos are very useful to learn a lot of things about engineering!
Amazing! Such an important discovery
2:34 what a god Tier walk cycle 😂
Plug walk
Fermi definitely deuced his pants
I am working on sustainable energy , it's very helpful, thank ya much
IT IS A MASTERPIECE. SO FLUENT EXPLANATION
Fermi - animated to be realistic and lifelike
Einstein - looks like a meme version of himself
Bro . Really thanks for this video . I have listen the same in class but I got to know complete information by this video
Very good content.
You identified the Thorium issue 100% correct!
Watched whole video. Very interesting 😊
I'm fascinated by Nuclear energy!
It Will Kill All
This is one of the most interesting things that we made. Thank you for posting this.
BTW: many beaches in Brazil are composed of monazite sand. A percentage of this sand is composed of thorium oxides. As a result, the beach is quite radioactive. So much so, in fact, that if you take a fun day on the beach, you would reach the yearly ionizing radiation limit set by the EU. And seeing that the half life of thorium is 14 billion years, this radiation isn't going away any time soon. 🙂
You are brazilian 👍🏻👍🏻
WE HAVE LARGEST RESERVE 🥱
This is awesome & good explaining with simply animation🙏😁....
Do Fusion and what's holding us back considering we have working thermonuclear devices in relation to Energy yield per weight of fuel etc.
Ty, great channel, keep'em coming!
I finally get it. Also appreciate the characters in your narrative. Can you bring back the chicken?
Excellent video
Thank you for this video. The world needs nuclear energy.
Very nice video 👏🏻👏🏻
Waiting for this one from so long.. Please make videos more related to nuclear power generation
Nuclear engineer banoge kya
@@RoYal-xz5ch already an electrical engineer.. Power Generation is part of electrical engg
Thankyou for knowledge
This was super good and clear. The ending was a cliffhanger though.. please explain
Thank you SO MUCH for this video.
I don't know why youtube waited 10 hours before recommending this video.
Nuclear energy is the future of energy in Earth. Solar and wind can f off.
Nuclear is so much more carbon neutral and so much more eco friendly,
It's about time all 7 billion humans know the exact science behind nuclear energy...
This really helped me with my 12th phy
Excellent video.
Hi hello, I just would like to make a question for better understanding.
I see in this video that the reaction is based on destabilization of the physical mass of nucleo and real values are not integer, so radioactivity is still in what remains untill the product find stability right? This means producing a lot of material that is shooting material all around right?
Awsome sir
Can you explain the last question on your next video?
Love your content! ❤️
Dear lesics
I kindly request you to make video on Ship dynamics ,its engine with your unmatchable graphics
We gain a lot from your videos
Thanks a ton
Love from India ❤️
Would you upload a video of how a touchscreen works?
Thanks for sharing

Nice Video
I know nothing about chemistry let alone nuclear matter but man this is some interesting stuff
Please make more videos on nuclear reactions or radioactive elements.
What happened to the spot video, will it ever be made public?
Since the neutron is s neutral charge, how do you accelerate it?
Can you pls make video on leaning of three wheeler like toyota i ride and other 3 wheel vehicle which tilt with wheel
Gotta love some of those animations lol 🤣😂
This my first time known that you don't need isotope to have chain reaction but only with the probability issue, same as the thing that I found the household microwave oven isn't provide the best frequency or wavelength for the water and so on molecules.
Can you make a video on extraction and features of virbranium metal 🙂
We can also use Plutonium 239 from U238 by using a Breeder reactors. Pu 239 is quite efficient in nuclear fission.
Nice
Dear chanel lesics, please make a video about how the hydraulic press works I would like to know from you who has a simple explanation method, and easy to understand

Please
Oh,that's actually pretty easy.
It's like a syringe.You pull in hydraulic oil with it and once pressed out it goes thru a smaller diameter pipe which by the law of physics has increased pressure.
To understand it easier take a sharp needle and blunt needle,if you try to penetrate something ofc you'd be penetrated by the sharp one because it has more pressure focused into a smaller area.
That's how they work as well,you take a big metal cylinder that can hold lots of pressure and you add inside a hydraulic oil which is low in viscosity but veeery dense,you pump the bigger cyilinder and it pushes everything into a smaller one out which then you work with(bending or whatever you need a press for)
To push the handle which moves the liquid around it's usually made with leverage by the same principle i explained before or an electro motor which pumps it.
Hope i got it right,correct me if there's a guy who understands them a lot.
Great video but i felt it ended abit suddenly, It would have been nice to wrap up with the explanation of WHY thorium is not currently viable...
Really useful! To impart general STEM knowledge to the first-year college students, I am writing about Fission reactors, *Thorium* reactors, Fusion research (ITER), etc. Your video helps me a lot. This is how one can encourage the students to get the general idea quickly, then learn more and excel in their fields. Thanks, Lesics !
Good sir, i am going to pursue nuclear engineering in future.
May you provide me some advice?
They probably didn't use thorium for power stations because it requires entirety of it to be new R&D, which costs at least tens of billions of dollars, if not hundreds. With uranium, the R&D was already done for them because they are piggybacking off of the research done for military weaponry.
Once I see a notification I know it's time for brains
ನಮಸ್ತೆ... ಪರಮಾಣು ಬಗ್ಗೆ ಮಾಹಿತಿ ನೀಡಿದಕೆ
ಧನ್ಯವಾದಗಳು ಸರ್ 🙏........
Please upload next video on fusion energy.
I asked my teacher this question when I was 15 years old in 2021. Now I have learnt the truth of fission
Hi team Lesics,
your videos are awesome. Really appreciate your efforts.
I think if you end the videos in a better way it will be even more better is what I feel. I'm in no way saying your videos are bad, just if the endings can be a bit smoother it'll make tremendous difference.
I hope this comment finds you.
Love from Bangalore,INDIA ❤️👏
Not from bangalore
This is from INDIA 😊😊
did i miss something? wich part of the mass converts to energy?
Thronium also one the nuclear fuel. it produce electricity moderately and also few neutrons released in fission reaction.
Please make a video on Noise cancellation in microphone 👍
why is boston dynamics video deleted?
How can a charge-leds particle like neutron be accelerated to hit a nucleus?
50 years ago I was a big fan but the endless promises of safety, price and time to build have changed my mind.
Oh yeah, cleaning up costs and wast storage ain't sorted.
Natural uranium can be used as fuel in a CANDU style reactor which uses heavy water as a moderator due to the high neutron economy of heavy water.
Isn't that also because of heavy water has relatively high (gamma, n) reaction cross-section?
@@farqilion8747 I think you mean it has a low reaction cross-section. Protium has a high affinity for neutrons because it already has an unpaired proton, but the deuterium nucleus is already balanced. So fast neutrons from the reactions collide but do not get absorbed easily and instead transfer energy to the deuterium as heat, and the neutrons themselves are quickly slowed to the thermal range where they can be more easily captured by a uranium or plutonium nucleus, and cause fertilization or fission, depending on the element and isotope.
@@sethapex9670 Sure heavy water absorbs significantly less neutrons than regular one does.
But what I meant is that cross-section for *(gamma, n)* (i.e. presence of photoneutrons in the core due to deuterium nuclei splitting by gamma rays generated by some of the fission products) is relatively high. And considering a relatively large amounts of heavy water in CANDU reactors, amount of additional neutrons is quite significant
@@farqilion8747 I've not heard of photoneutrons before now, but I just looked into it and I suppose it makes sense that that may be likely. The energy of those gamma photons would have to be pretty high though, since they're essentially causing fission in an element that should pretty much only be energetically capable of fusion and decay
Please make a video about Padma Bridge in Bangladesh.
please for the Lesics team, I want an explanation about the earth nail hammer / pier in Indonesian, please do it as soon as possible 🙏🙏.. I'll be waiting 😁😁 thank you,,,Greetings from Indonesia🇲🇨
I have to make it so it want to know that in which shape you have heated it in its original shape
5:50 Of the 64 kilograms, only about 1 kilo actually fissioned. The rest blew apart and turned into fallout.
How do we know this?
@@ibnewton8951 The scientists based it on the explosive yield. The estimated 15 kt explosion equates to 1 kg of matter converted into energy. As the blast damage from the chemical explosives would be negligible, the blast therefore was caused by the conversion of mass into energy. Einstein was nice enough to provide us with the math on that one. :) EDIT: I goofed, see my follow up comment. I'm leaving this one because I'll admit when I'm wrong about something.
Argh, I misquoted. The energy release was from fission byproducts, not the conversion of mass into energy. 1 kg of mass converted directly into energy would yield over 20 megatons of blast. The amount of mass converted into energy in Little Boy was about 1 GRAM.
@@doggonemess1 And that's a perfect prespective of how insanely inefficient is the reactions we use on the living on converting the mass into energy. A combustion of Hydrogen & Oxygen to make water, which is practically one of the cleanest one, converts 0.000000001% of mass into heat energy. The Fission of Uranium converts 0.08%. The Fusion of Hydrogen to Helium converts 0.7%. source by minutesphysics.
@@dy7296 We need some antimatter reactors. Get that rate up to 100%. XD
2:30 that's how I rush to the toilet after the coffee kicks in...
Good wark
That walk when he rushed to the lab though 😅
good video, but still left Thorium very shallow. Why are there political problems if it has more advantages?
I have a question if any one could help me with the answer:
When the fuel rods are placed with Uranium in a power planet, how we introduce the neutron? the rods are sealed does it works with electric shock, or giving it heat? or how?
7:20 "You can't make bombs from it" There, fixed it.
dirty bombs

we've all heard about Einstein, Oppenheimer.
but i've never heard about Enrico Fermi, the real dude in my opinion
so the thorium guy couple year ago was right nice to know.
Couldn't the "waste" be enriched for a lesser use such as submarine or ship reactor fuel? Or perhaps a heating source for polar weather stations and hotels?
we've been doing this for 20 years but people still think we never thought about it.
I want to be a member of lesics team
But i have not much more money for joining .
Give me some ideas to how make videos on educational topics and also how to make video.And from which application.
Thank you
Respected sir
I hate chemistry class during my high school 5 years ago, too bad that I only now realized how significant it is.
einstein: _running_ fermi's gotta be doing something, right?! i need to weigh his samples!
element ke molecular structure ke bare me 3d animation me bataye
❤️
✌
What would happen if chain reaction wasn't stopped??
Can we get energy from ionizing radiation coming from high-level radioactive WASTE?
Not really I guess. Energy producted from the decay is only about 7% of what would generate during fission reaction. Besides, that's right after fission stops, and further this amount exponentially decreases over time
Only 200 years! I expected way more t.t
The rushing part was more interesting 2:34
I would really appreciate a climate change video from you guys, infographics easy to understand for people who wouldn't be otherwise inclined, stay awesome and keep up the good work!
7:17 you mean bacause it can't be used to make a nuke?
"Mr. Albert Einstein" should be "Dr. Albert Einstein". Give him his due.
The US planes that dropped the atomic bomb on Hiroshima and Nagasaki (5:40) are drawn incorrectly: the stars on the wings should be white. Red stars were on the wings of Soviet aircraft.
Finally going back to the good quality of content, before that guy decided he had to be in every video
That Einstein is gonna give me nightmares
Let explain how fussion makes
Why is energy released in nuclear fusion ?
3:32 you said "atoms are mostly made up of hollow space". It is incorrect to state that. The electron cloud is spread out over a large volume, with the highest probability of finding electrons near the nucleus and a lower probability of finding electrons further away from the nucleus. This results in the appearance of empty space within the atom. So while atoms do contain a significant amount of empty space, it is not accurate to say that they are "mostly made up of hollow space". :D
Very good video, and i am very happy that you specified disadvantages and advantages. Well done. In my opinion the disadvantages still vastly outweigh the advantages, especially regarding nuclear waste management and incredibly massive costs. Thorium reactors don’t yet exist and have major technical issues. Thank you
They probably didn't use thorium for power stations because it requires entirety of it to be new R&D, which costs at least tens of billions of dollars, if not hundreds. With uranium, the R&D was already done for them because they are piggybacking off of the research done for military weaponry.
Closed cycle (waste = new fuel) solves this
@@dmitrii336 Sadly there are no closed cycle nuclear sites operating today. Maybe the next generation will use this, but we still have thousands of tons of waste that cannot be processed except to store them in old leaking ponds or bury it deep underground and pray and hope for the best.
@@Greguk444 they're already in construction (Russian BREST fast-neutron for example) and I think will be quite common by mid century.
This video didn't talk about how fusion (thermonuclear) reactions work.
"political and economic reasons" being that nobody has yet asserted the political will to do it.
