The first parts of this didn't sound too crazy compared to some of the other videos you've done, but the longer the video went on, it was like we were descending further into the depths of engineering madness. Astronomy is indeed insane.
I think this wonderful madness started with the Mars rovers being lowered onto the surface - we learned that the outside-the-box solutions are turning out to somehow actually work. What a mind-opening time for space nerds! It may be engineering madness, but if it works, I guess it wasn't madness after all, right?
1. Crazy rover drops on Mars. 2. Insane JWT engineering with hundreds of single points of failure .... that didn't fail. 3. Parker Probe going in at less than 5% of the distance from Earth to Sun. I'm starting to think fusion is gonna happen.
The small details that took literal centuries for humanity to discover and perfect to this point is what was mind blowing to me. Niobium wire insulated by sapphire sounds so simple.. yet also sounds like science fiction. I feel like Carbon foam and Niobium C-103 alloy could be the subject of entire Real Engineering videos. How do we even get to that point?

How do we even collectively get to that point?
Carbon foam i dont know, but Niobium c-103 is likely something someone put together because they were curious or an engineer needed something for a high temperature project, and the material scientists took materials that were known to be able to perform well under high temps. Material science is a well developed study field, go look into it if you're curious, as even some simple looking steel materials have insane backgrounds.
@@FierceFire14 Exactly, the new knife super steel Magnacut developed by Dr. Larrin Thomas, a metallurgist has 2.00% of Niobium along with 4.00% of Vanadium are aggressive carbide formers with Vanadium being the hardest carbide metal known, and Niobium is right behind it being as hard as tungsten carbide. It is in several PM or particle metal knives. In Magnacut it keeps the Chromium from forming its brittle carbides.
Scientific progress works kind of like baloon. We build up pressure with a ton of research over the years that shows clearly what we know, what we don't and what is in demand. Then when the pressure is enough usually one science team makes a breakthrough and gets a lot of credit. But in reality when such breakthrough becomes possible, who exactly does it becomes more a matter of chance rather than particular scientist's genius. All science is important. Except the fake one.
@@gigakoresh The biases of many scientists I've noticed over the years of working in the aerospace field also holds back science as well. Especially in biology.

@@bobbertee5945I think when people get to that level it’s just like learning a language. They’re comfortable with all the components that make up the equations like words in a language and have probably solved stuff that “complex” to us so many times that they’ve already done all the hard thinking about it when learning. I’m sure there are many things you’re capable of doing which would look impressive to the uninitiated just in the same way you described looking at those people solving complex math
Small nitpick. While Falcon Heavy is the highest payload to orbit currently available, Delta IV Heavy has higher interplanetary payload because of its significantly more efficient upper stage
@@aronseptianto8142 Upper stages are exclusive to the launch vehicle except for a few special cases. Falcon Heavy has a kerosone and liquid oxygen upper stage which is efficient and cost effective for lower earth orbits. Delta IV Heavy's upper stage is a liquid hydrogen and liquid oxygen upper stage. This is expensive and not very efficient for lower orbits but it's much better for high orbits and interplanetary missions. Parker solar probe needed as much velocity as it could possibly get from launch in order to make the mission work. Falcon Heavy may be "more powerful" but Delta IV Heavy was able to provide more velocity to the probe, which is why it was used.
@@aronseptianto8142 You are correct but they are rarely booster agnostic. The efficiency of the Delta upper stage is mostly lent by its hydrogen engine which has far higher exhaust velocity than kerolox. To do the same, SX has to design their own hydrogen upper stage which I don't see in the near future. Oncee Superheavy is operational however, you can pretty much bolt in any upper stage into it, lol. No need for specialized adapters. Just chuck it into the payload bay, hehe. (With some nuance of course)
@@aronseptianto8142 The second stage is starship itself, superheavy being the first stage. If you wanted to add a third stage for some reason into the payload bay of starship you could, I'd imagine. It would probably either use compressed springs to launch the payload out of the bay or I could even see a world where a similar sort of roll/yaw maneuver is used to have the payload eject itself, similar to how starlink satellites are deployed. In all likelihood however, one would probably just use starships second stage for these trips instead of a dedicated 3rd stage.

Some clarification of what "temperature" means in different contexts is probably needed. When you say the temperature is "only" 3000ºC at the surface of the sun but over 500000ºC in the corona, a clarification is in order because temperature has a completely different meaning than what most people would expect when talking about mostly empty space. That is, the corona has a "high temperature" but a "low heat content" due to it being mostly empty space - a thermometer placed there would *not* show hundreds of thousands of degrees. Otherwise the later part of the video, where you mention they use materials like tungsten that have a melting point of 3400ºC would make no sense. In particular, you mention they can get about 3500ºC with the concave mirrors at the Odellio Solar Furnace for testing, and that such temperature is *twice* what the heat shield is expected to encounter...
@@edwardsl8016 What they mean is that the temperature of any particle is far higher, but your odds of encountering them are far lower. That means the thermal density is, on net, lower than at lower altitudes where the temperature is nominally lower. As for cooling, a carefully designed system could keep water from boiling by virtue of not giving it anywhere _to_ boil(though I doubt it's actually pure water).
@@edwardsl8016 No, the equipment being hotter than water boiling temperature is not necessarily a problem. If you circulate the water quickly and if you choose materials in the heat exchanger carefully so it provides enough heat transfer to cool the equipment but not heat the water too quickly, the water can circulate back in the shielded area before it boils. As long as the water keeps moving, it won't reach high enough temperature to boil over. Or they could just use steam as heat transfer medium rather than liquid water, that should work just fine as well.
Hi, great video! A few points to clarify on the fusion side. The ‘able to produce 70% of the input energy’ is a little inaccurate. The plasma produces, in the form of heat, 70% of the power heating it. However, that isn’t 70% of the input electrical power. There are efficiency losses between the electrical power fed to the heating systems and the amount of heating power that actually heats the plasma. Likewise, the power produced is in the form of heat, not electricity, and you need to produce a fair bit more heat to compensate for efficiency losses when producing electricity. ITER will not be hooked up to a system to generate electricity from heat. The next reactor that is planned after ITER is DEMO, which is supposed to produce electricity. The UKs STEP reactor is an electricity producing demonstration device scheduled for completion in 2040. Also, ITER will not really be finished in 2025. That’s the first stage, where they can test when they have assembled so far with realtively low performance plasmas. If all looks good they will continue with assembly. The next (thermal) energy producing ITER operations will use a deuterium-tritium fuel mix and aren’t scheduled until around 2035. Even then, no electricity will be produced. DEMO is being designed currently and won’t be online (assuming it ever gets approved) until at least 2050. Many private fusion companies have popped up over the last decade that aim to have electricity producing demonstrator devices in the early 2030s. The faster pace of private companies is a result of incorporating new technologies that either allow the reactors to be built smaller and hence much more quickly, or have some novel approach. Some such technologies weren't around when ITER was being designed, another drawback to the long time it has taken to construct it. The reason ITER is taking so long is, among many other factors, due to its immense size. When it comes to tokamak fusion reactors, building bigger does move you toward more fusion relevant conditions in your plasma, but at the cost of the devices taking longer to be built. New technologies have emerged since ITER started construction, which enable the magnetic field strength of the fusion reactor to be much larger. This also moves the reactor toward more fusion relevant conditions, without having to make it enormously large. Hence you can build such devices much quicker. Hope this was informative! Great video as always.
Thank you, I didn't have to write up basically the same thing. Though I have very strong doubts about every single novel fusion startup as non of them are willing to show accurate simulations of how their system is supposed to work. I hope their investors at least are getting a more behind the scenes look instead of buying into snake oil.
I found this video very informative on the topic: ua-cam.com/video/LJ4W1g-6JiY/v-deo.html My key takeaway: It's about Q, the ratio between power out / power in. We want Q > 1 to harvest energy. We hear numbers like Q = 0.7 like here, but that's misleading. Because there is more than one Q! What ultimately matters is Qtotal, which divides the total amount of electricity gained by all the power needed to run the facility (including cooling, machinery, and whatnot). What's often reportet is a different Q, for example Qplasma. Yes, we might get the plasma to return 70% of the energy we put in, and that's great, but that number ignores cooling and other processes which might consume vastly more energy than the plasma itself. And conversion losses, as you say. The relevant Qtotal is still at or below 0.1 afaik.
Great summary! Basically you have given "The current State of Fusion research" all in one UA-cam comment. I would only like to add one important point on why it takes so long to build ITER: The project, actually dating back to the Reagan presidency (!), was set up to be scientifically profitable to all participating nations. That's why all construction work that could be distributed to different nations was split up that way. In the end, every ITER partner was supposed to have learned everything necessary to build the thing all over again by themselves should they want to. Now take this horribly inefficient distribution that was intentional and add the seemingly unavoidable mismanagement every great project seems to suffer from and you've got one of the main reasons why ITER is delayed by decades and costs billions more than was originally projected.
As an engineer myself, I absolutely love engineering and all that it has to offer. I love how we use our knowledge and problem solving skills to create something useful and beautiful! This “I Love Engineering” channel is a great example of how engineering can be made entertaining, showing some of the best engineering breakthroughs. It also does a great job highlighting the talented engineers that make up the backbone of our society. It really encourages me to learn more about engineering and stay on top of all the new developments out there. Kudos to this channel!
It's amazing how the engineering of the Parker Solar Probe required other engineering projects that are all worthy of "The Insane Engineering of [X]" videos in their own right. Like both from construction and also in experiment design.
Yeah, it’s great that these videos show people why “random” research is important. And who knows what earth shattering technologies might be created with the data we receive from probes like this.
I remember the day it launched. I was at Disney world with my parents and we found out about the launch the day before. Luckily, we were able to see the launch since our hotel wasn't to far from Kennedy space center. I remember waking up at around 2 in the morning with so much excitement and putting on the nasa channel. Then, I saw a big glowing ball which I knew was the rocket. It has been the only rocket launch I've ever seen in person and it was an awesome experience
17:09 They have recently generated more energy than the energy used to start the fusion reaction. It's funny, 10 months ago they probably thought that it would take 50-100 years to achieve that
They didn’t really. The fusion reaction created 1/50th of the “total” power it used to do the experiment. What your referring to is that it produced more energy than it required for the lasers to start the reaction, but that doesn’t account for all of the other power losses in the system. Do a little more research on it and you’ll find we were a little mislead on that break through. We still are very very far away.
@@ChristopherGuilday This is true. The net energy of the lasers was 2.05mW. However due to the inefficiency of lasers they probably consumed a 100mW+ to produce those lasers. However, what happened was a big milestone and it's only a matter of time until fusion experiments get increased funding and are able to accelerate their progress.
What really matter is the amount of money going on vs amount of money out. Nuclear fussion doesn't even need to generate more energy out than in to be profitable, if you can produce and sell something else.
This is the thing I love about exploration, especially when people say, why are we doing this. Not only is it giving us interesting information, but it makes us invent new technology which may just come in useful in every day life in ways we can’t even imagine yet.
They act like money and time that goes into space exploration just goes into the void. We can use tech we put into space exploration for uses here in Earth, plus the money goes to people here on Earth

If anyone was wondering why Parker was flown on a Delta IV Heavy instead of a Falcon Heavy, the Delta Cryogenic Second Stage is a hydrolox stage with a RL-10 engine. The Falcon Heavy uses a kerolox Merlin stage. Rockets have different metrics, so calling one 'most powerful' is a big dishonest. Essentially, the hydrolox stage has a greater throw weight over long distance. FH can lift more to LEO than DIVH, but when you are talking interplanetary missions FH starts to lose out

This is true for a (partially) reusable Falcon Heavy launch, but a fully expendable Falcon Heavy can still send more mass than the Delta IV Heavy in high dV missions even though it is less efficient.
Plus there is the fact that Delta is more reliable. Falcon heavy is very new rocket, so if you want to put a 10 billion dollar telescope that launch cost doesn't even make a dent.
@@Tim_88524 Expendable FH may _technically_ be capable of a mission like this, but SpaceX will likely never fly FH in that format. They only have 6 or so boosters around these days, they rely on reuse to maintain launch cadence. And that also doesn't take into account the Solid third stage which has never been done on a Falcon family rocket but has been done multiple times on the Delta IV family. There are other factors but they are complex and multi-faceted

Humans, as a species, are really good at throwing things with accuracy. We have come up with lots of throwing alternatives to give us more speed, power, distance...such as a long sticks which are used to launch another object (spear. Lacrosse ball. Hockey puck. Etc.) Tension based launchers that can be used to hurl an object (bows and slingshots) I like to think of rockets and just one version of explosion-powered throwing. And with some of these we can adjust the throw "midair" now. We just have to crunch some math to make sure our "throw" is right, because we have reached such ridiculous proportions in our range.
When you consider the insanely complicated maths involved in throwing something accurately given distance, height, wind, movement of the thrower, movement of the recipient etc, it makes just being able to throw a ball to your friend as you're walking down the street a really impressive thing. Throwing that ball to accurately be captured by the gravity of two object 1000s of km away is great but still, throw a ball to your friend and you've pretty much nailed it when considering you haven't fired up a computer to do it for you.

Yep, given the densities of the corona i'd bet a block of ice at its melting point has more internal energy, since the density of the corona iirc was in the order of 10^-9 gcm^3
@@kevinkarlwurzelgaruti458 Temperature is the measurement of energy transferred from one mass to another. And the total amount of energy transferred depends on how much mass there is, with higher energy, to transfer to the lower energy mass. For example: If you drop a grain of sand from 100 mts. high on your head, you won't even feel it. If you drop a block of 100kg of concrete from 100 mts. high on your head, it will kill you. Both the grain of sand and the block start with the SAME energy LEVEL (like saying they start with the same temperature level). But the block has WAY more energy MASS that will transfer to you. So, more density means more total amount of energy available to affect the lower energy mass. Now, in the corona of the sun, the energy mostly comes from radiation. The radiation density is VERY high. And the particle density is very low. That's why simply hiding behind a heat shield (which is a bad name, it's actually a radiation shield) is enough to protect the ship. Because there is no mass around it that carries any energy. And rays only go straight, and don't bend around the shield. If there were a substantial amount of mass, it would go around the shield and transfer a lot of energy in a very short time, enough to raise the energy level of the ship's mass, to a point were it would break or melt. There is mass in the corona, but it is very little (low density) so the total amount of energy transferred to the ship is small, and it doesn't raise the ship's energy too much.
Absolutely bonkers! The expertise and sheer hours spent on this mission, and the amount of evolution taken to get to this point, is truly mind-melting!
Could you take a look at the engineering and applications of sodium ion batteries? I’ve been hearing about them for grid storage, but I would love to hear your analysis.
Been hearing about sodium batteries for many years, haven't seen much progress in the news so I'm really interested in seeing what I've been missing. I hope he makes a video on the topic too
For grid storage you have plenty of options for a battery. For example you can simply suspend a weight in the air and move it up and down based on demand and supply. That’s pretty much a gravity battery and would work well for grid storage. We already use pumped hydro as a sort of battery in many places in the world so grid storage isn’t as big of a problem as it seems. The bigger problem is batteries for trucks, or other heavy equipment since you have way more constraints in such an application.

The scientists and engineers who worked so hard to design a probe that could touch the sun must be disappointed to know that nowadays they could just walk outside their homes to collect particles of corona.
Science shows its intelligence sparing no expense too great, nor distance too far, in areas in which it most determined to succeed, but also, its utter contempt for human life in avoiding those issues such as corporate greed and corruption that affect, invade and control our daily lives with no prospect for a brighter future, outside of their own comforts.
I am a Nigerian mechanical engineering (not a scammer ) student, and I have been watching your channel for about 4 years now, and with every video I watch I think more and more as a real engineer , So thank you. Ps the insane engineering series is the best thing since sliced bread thanks.
Great video as always. I have just one issue with it: you said the process of changing the altitude of apoapsis or periapsis was named a Hohmann transfer. This is not true. A Hohmann transfer is the combination of two of the maneuvers you described, performed with the goal of elevating or lowering the orbital altitude as a whole. i.e. going from a 450km(Apoapsis) x 400km(Periapsis) orbit to a 1200km x 1100km orbit could be achieved via Hohmann transfer, going from a 450km x 400km orbit to a 450km x 800km orbit could not, as that can be done in one maneuver. The defining characteristic of a Hohmann transfer is that it consists of two maneuvers, done sequentially at opposite points in the orbit, both of which are either prograde or retrograde.
The reason for the corona being so hot is because that's the admin-only barrier, dude. Only reason the parker probe got through was because its buggy entity model abused spaghetti code to glitch past this barrier

Actually, flames have EXACTLY the same tendency. The center of a flame tends to be far cooler than the tip. Whether the tip is the hottest, or a point between the center and tip, depends on the kind of fire. But the important part is that fire gets hotter as you move away, much like a star. In both cases, this is because the chemical reaction progresses as it moves outward.
In the case of the Sun it's most likely due to magnetic fields adding energy to the particles, and since the gas gets more and more tenuous (less dense) the farther you get away from the Sun there's less for them to collide with and lose the energy so they tend to get very high speeds = high temperature.
ERM... except there's no chemical reaction involved in the sun. Combustion only happens in presence of oxygen. These are nuclear reaction, which is a very different thing!
@@Sledr1994 Okay, yes, technically anything involving the nucleus is not chemistry. But a similar event is occurring, where for a while the temperature rises as distance increases in a perfectly reasonable way.
Different process. Unlike in a flame where the heat generating reaction occurs throughout including at the surface, The heat generating reaction in the sun (I.e. fusion) only occurs in the core of the star where the pressure is high enough to overcome Coulomb repulsion. Whatever heats the upper solar atmosphere has to be a different process hence the theories about it being magnetic fields transferring energy.
Very well made. Thank you. I am only bothered by one thing. In my humble opinion, 45 billions are not much for a world changing experiment. (talking about ITER) humans spend multiples of this amount on war. Imagine what we could achieve with so much budget in science and engineering.
ITER's budget was 5 bilion euro when I first read about it in the 2000's. According to wikipedia its starting budget was 6 bil. As much as I like fusion, I afraid that ITER is more about politics and prestige than about science.
Also remember, that private fusion startups are getting to net positive energy even sooner at a fraction of the cost of ITER! This may seem like an unpopular opinion, but just imagine how much more humankind could have accomplished if so many resources and years of effort had never been siphoned into government war making or government research!
@@johnfisher3380 ITER has itself created new and improved technology, it's not a total loss. Those net positive stories from startups are also still far from close, they're still just nanoseconds of time and unable to sustain it. ITER with it's large size is theoretically far more capable of sustaining net positive energy. No single private company is able to do this project. That is why tons of companies have been tasked with making the best thing possible for ITER, like the world's most powerful electromagnet for containment. Collaboration like this takes a lot of time and a lot of work to make sure everything works together and is following spec. Some of the parts took over a decade to develop because of the technical complexity and not existing before.

Great video with great information. And the narration is perfect for speeding up to 2X to save time. I'm really excited about this kind of heat deflection technology and sun approaching probes. It's one step closer to star lifting, something that could, if we crack it, could pave the way for space bases and solar collection mega structures. (I just realized that the plans of most orbital solar collectors rely on setting up mercury and mining it out to get material, but if we can start star lifting before that, it would save a lot of time and resources.)
These space engineering videos are always the highlights of the channel The creativity and the insane ideas to overcome the most extreme conditions is always facinating
It blows my mind how fast we have been advancing the last 100-200 years. Its the most advancements in a short time that humans have ever made in their existence. I cannot even imagine what another 100-200 years will bring. The more advancements we make, the faster n faster we advance its like a runaway train. Especially once AI gets better and even starts teaching us things n helping us advance even faster, its gonna be a wild ride with no way to stop it unless a major worldwide disaster happens and sets us back. Im 30 now and kinda wish i was born later so i can see more of the crazy stuff we will come up with but at the same time i kinda dont cuz the future is shaping up to be a bit scary and possibly distopian
Another 100 or so yrs we will be along way away from this planet maybe not everyone I just hope we get it right and leave and can stay alive before we blow this planet up
The atmosphere of the Sun being the hottest part could be due to the fact solar flares and radiation are launched up so the atmosphere gets more heating than the "surface" as the heat giving out by the core of the Sun dissipates as it moves up so the "surface" is not actually that hot.
There is a slight error at 3:38. You quote an orbital velocity of 9.2km/s for earth. Whereas, the actual figure is 7.8km/s. The 9.2km/s figure is, however, often quoted as a rule of thumb the delta v (potential acceleration) needed to reach orbit. With the 1.4km/s discrepancy being due to the inefficiencies due to "gravity loss" (where the rocket is burning fuel to fight gravity rather than accelerate) and atmospheric drag involved in rocket launches. I would appreciate if you would pin this comment or add a note to the discription to clarify this. Thanks and keep up the great work
Appreciate your effort detailing such a complicated mission to this extend. It was great to watch though my brain had a thermal shutdown. Solar flares !!! :D

According to the video, the parker solar probe had to face 3500 C temperature for example at 14:20, but at 1:28 you said corona has a temp more than half a million C. Have I been mistaken and didn't watch the video properly? or is there a mistake in the information provided in this video? Because I cant imagine a man made object surviving half a million C temp! Apart from this, I really enjoyed the video kudos to this channel!
The corona gets up to million or more degrees, but it is not all encompassing in that while the particles in there attain that kind of 'heat', they are relatively few and far between and thus the actual temperature that the probe experiences within the corona is a lot less. Thus, it's all about heat transfer. Liken it to putting your hand in 50-degree (celsius) water--which is hot--and then 50-degree air... the latter feels nowhere near as 'hot'. That heat shield is amazing plus the probe has cooling.
The sun is kind of a mood to be honest, impossibly hot in the surrounding area, but on the surface it's nice and warm; only those few willing to wether and break through the exterior layer will get to experience how pleasant the interior really is

Carbon foam i dont know, but Niobium c-103 is likely something someone put together because they were curious or an engineer needed something for a high temperature project, and the material scientists took materials that were known to be able to perform well under high temps. Material science is a well developed study field, go look into it if you're curious, as even some simple looking steel materials have insane backgrounds.
@@FierceFire14 Exactly, the new knife super steel Magnacut developed by Dr. Larrin Thomas, a metallurgist has 2.00% of Niobium along with 4.00% of Vanadium are aggressive carbide formers with Vanadium being the hardest carbide metal known, and Niobium is right behind it being as hard as tungsten carbide. It is in several PM or particle metal knives. In Magnacut it keeps the Chromium from forming its brittle carbides.
Scientific progress works kind of like baloon. We build up pressure with a ton of research over the years that shows clearly what we know, what we don't and what is in demand. Then when the pressure is enough usually one science team makes a breakthrough and gets a lot of credit. But in reality when such breakthrough becomes possible, who exactly does it becomes more a matter of chance rather than particular scientist's genius. All science is important. Except the fake one.

Small nitpick. While Falcon Heavy is the highest payload to orbit currently available, Delta IV Heavy has higher interplanetary payload because of its significantly more efficient upper stage
do correct me but i thought the upper stage is interchangeable?
@@aronseptianto8142 Upper stages are exclusive to the launch vehicle except for a few special cases. Falcon Heavy has a kerosone and liquid oxygen upper stage which is efficient and cost effective for lower earth orbits. Delta IV Heavy's upper stage is a liquid hydrogen and liquid oxygen upper stage. This is expensive and not very efficient for lower orbits but it's much better for high orbits and interplanetary missions.
Parker solar probe needed as much velocity as it could possibly get from launch in order to make the mission work. Falcon Heavy may be "more powerful" but Delta IV Heavy was able to provide more velocity to the probe, which is why it was used.
@@aronseptianto8142 You are correct but they are rarely booster agnostic. The efficiency of the Delta upper stage is mostly lent by its hydrogen engine which has far higher exhaust velocity than kerolox. To do the same, SX has to design their own hydrogen upper stage which I don't see in the near future. Oncee Superheavy is operational however, you can pretty much bolt in any upper stage into it, lol. No need for specialized adapters. Just chuck it into the payload bay, hehe. (With some nuance of course)
@@fcgHenden how would staging even be done in a super heavy kind of rocket?
would it do the explosive charge but sideway?
@@aronseptianto8142 The second stage is starship itself, superheavy being the first stage. If you wanted to add a third stage for some reason into the payload bay of starship you could, I'd imagine. It would probably either use compressed springs to launch the payload out of the bay or I could even see a world where a similar sort of roll/yaw maneuver is used to have the payload eject itself, similar to how starlink satellites are deployed. In all likelihood however, one would probably just use starships second stage for these trips instead of a dedicated 3rd stage.

Some clarification of what "temperature" means in different contexts is probably needed. When you say the temperature is "only" 3000ºC at the surface of the sun but over 500000ºC in the corona, a clarification is in order because temperature has a completely different meaning than what most people would expect when talking about mostly empty space. That is, the corona has a "high temperature" but a "low heat content" due to it being mostly empty space - a thermometer placed there would *not* show hundreds of thousands of degrees. Otherwise the later part of the video, where you mention they use materials like tungsten that have a melting point of 3400ºC would make no sense.
In particular, you mention they can get about 3500ºC with the concave mirrors at the Odellio Solar Furnace for testing, and that such temperature is *twice* what the heat shield is expected to encounter...
Yeah that would have been worth explaining cuz as is it's confusing, thanks
So empty space is hotter? But also confusing was the cooling by water of solar panels 13:14 , wouldn't that be vapor, since water vaporizes at 100ºC?
@@edwardsl8016 What they mean is that the temperature of any particle is far higher, but your odds of encountering them are far lower. That means the thermal density is, on net, lower than at lower altitudes where the temperature is nominally lower.
As for cooling, a carefully designed system could keep water from boiling by virtue of not giving it anywhere _to_ boil(though I doubt it's actually pure water).
@@edwardsl8016 No, the equipment being hotter than water boiling temperature is not necessarily a problem.
If you circulate the water quickly and if you choose materials in the heat exchanger carefully so it provides enough heat transfer to cool the equipment but not heat the water too quickly, the water can circulate back in the shielded area before it boils.
As long as the water keeps moving, it won't reach high enough temperature to boil over.
Or they could just use steam as heat transfer medium rather than liquid water, that should work just fine as well.
so I can feel heat here on earth but space isn't warm.. makes sense
Hi, great video! A few points to clarify on the fusion side. The ‘able to produce 70% of the input energy’ is a little inaccurate. The plasma produces, in the form of heat, 70% of the power heating it. However, that isn’t 70% of the input electrical power. There are efficiency losses between the electrical power fed to the heating systems and the amount of heating power that actually heats the plasma. Likewise, the power produced is in the form of heat, not electricity, and you need to produce a fair bit more heat to compensate for efficiency losses when producing electricity. ITER will not be hooked up to a system to generate electricity from heat. The next reactor that is planned after ITER is DEMO, which is supposed to produce electricity. The UKs STEP reactor is an electricity producing demonstration device scheduled for completion in 2040. Also, ITER will not really be finished in 2025. That’s the first stage, where they can test when they have assembled so far with realtively low performance plasmas. If all looks good they will continue with assembly. The next (thermal) energy producing ITER operations will use a deuterium-tritium fuel mix and aren’t scheduled until around 2035. Even then, no electricity will be produced. DEMO is being designed currently and won’t be online (assuming it ever gets approved) until at least 2050. Many private fusion companies have popped up over the last decade that aim to have electricity producing demonstrator devices in the early 2030s. The faster pace of private companies is a result of incorporating new technologies that either allow the reactors to be built smaller and hence much more quickly, or have some novel approach. Some such technologies weren't around when ITER was being designed, another drawback to the long time it has taken to construct it. The reason ITER is taking so long is, among many other factors, due to its immense size. When it comes to tokamak fusion reactors, building bigger does move you toward more fusion relevant conditions in your plasma, but at the cost of the devices taking longer to be built. New technologies have emerged since ITER started construction, which enable the magnetic field strength of the fusion reactor to be much larger. This also moves the reactor toward more fusion relevant conditions, without having to make it enormously large. Hence you can build such devices much quicker. Hope this was informative! Great video as always.
Do you think ITER will be irrelevant by the time they are ready for deuterium fueled experiments?
Thank you, I didn't have to write up basically the same thing.
Though I have very strong doubts about every single novel fusion startup as non of them are willing to show accurate simulations of how their system is supposed to work.
I hope their investors at least are getting a more behind the scenes look instead of buying into snake oil.
I found this video very informative on the topic: ua-cam.com/video/LJ4W1g-6JiY/v-deo.html
My key takeaway: It's about Q, the ratio between power out / power in. We want Q > 1 to harvest energy.
We hear numbers like Q = 0.7 like here, but that's misleading. Because there is more than one Q! What ultimately matters is Qtotal, which divides the total amount of electricity gained by all the power needed to run the facility (including cooling, machinery, and whatnot). What's often reportet is a different Q, for example Qplasma. Yes, we might get the plasma to return 70% of the energy we put in, and that's great, but that number ignores cooling and other processes which might consume vastly more energy than the plasma itself. And conversion losses, as you say. The relevant Qtotal is still at or below 0.1 afaik.
Great summary!
Basically you have given "The current State of Fusion research" all in one UA-cam comment. I would only like to add one important point on why it takes so long to build ITER:
The project, actually dating back to the Reagan presidency (!), was set up to be scientifically profitable to all participating nations. That's why all construction work that could be distributed to different nations was split up that way. In the end, every ITER partner was supposed to have learned everything necessary to build the thing all over again by themselves should they want to.
Now take this horribly inefficient distribution that was intentional and add the seemingly unavoidable mismanagement every great project seems to suffer from and you've got one of the main reasons why ITER is delayed by decades and costs billions more than was originally projected.
Wasn't the record 10% a decade and a half ago, though?

17:09 They have recently generated more energy than the energy used to start the fusion reaction. It's funny, 10 months ago they probably thought that it would take 50-100 years to achieve that
They didn’t really. The fusion reaction created 1/50th of the “total” power it used to do the experiment. What your referring to is that it produced more energy than it required for the lasers to start the reaction, but that doesn’t account for all of the other power losses in the system. Do a little more research on it and you’ll find we were a little mislead on that break through. We still are very very far away.
@@ChristopherGuilday This is true. The net energy of the lasers was 2.05mW. However due to the inefficiency of lasers they probably consumed a 100mW+ to produce those lasers. However, what happened was a big milestone and it's only a matter of time until fusion experiments get increased funding and are able to accelerate their progress.
What really matter is the amount of money going on vs amount of money out. Nuclear fussion doesn't even need to generate more energy out than in to be profitable, if you can produce and sell something else.

If anyone was wondering why Parker was flown on a Delta IV Heavy instead of a Falcon Heavy, the Delta Cryogenic Second Stage is a hydrolox stage with a RL-10 engine. The Falcon Heavy uses a kerolox Merlin stage. Rockets have different metrics, so calling one 'most powerful' is a big dishonest. Essentially, the hydrolox stage has a greater throw weight over long distance. FH can lift more to LEO than DIVH, but when you are talking interplanetary missions FH starts to lose out

This is true for a (partially) reusable Falcon Heavy launch, but a fully expendable Falcon Heavy can still send more mass than the Delta IV Heavy in high dV missions even though it is less efficient.
Plus there is the fact that Delta is more reliable. Falcon heavy is very new rocket, so if you want to put a 10 billion dollar telescope that launch cost doesn't even make a dent.
@@Tim_88524 Expendable FH may _technically_ be capable of a mission like this, but SpaceX will likely never fly FH in that format.

Humans, as a species, are really good at throwing things with accuracy.
We have come up with lots of throwing alternatives to give us more speed, power, distance...such as a long sticks which are used to launch another object (spear. Lacrosse ball. Hockey puck. Etc.)
Tension based launchers that can be used to hurl an object (bows and slingshots)
I like to think of rockets and just one version of explosion-powered throwing. And with some of these we can adjust the throw "midair" now.
We just have to crunch some math to make sure our "throw" is right, because we have reached such ridiculous proportions in our range.
gets even better when mathematical equations are added ...precision
When you consider the insanely complicated maths involved in throwing something accurately given distance, height, wind, movement of the thrower, movement of the recipient etc, it makes just being able to throw a ball to your friend as you're walking down the street a really impressive thing. Throwing that ball to accurately be captured by the gravity of two object 1000s of km away is great but still, throw a ball to your friend and you've pretty much nailed it when considering you haven't fired up a computer to do it for you.

Temperature is a very abstract concept. Especially at such low densities.
Yep, given the densities of the corona i'd bet a block of ice at its melting point has more internal energy, since the density of the corona iirc was in the order of 10^-9 gcm^3
The earth is flat and actually Satan has taken credit for the ball earth thing actually.
@@kevinkarlwurzelgaruti458 Temperature is the measurement of energy transferred from one mass to another.
And the total amount of energy transferred depends on how much mass there is, with higher energy, to transfer to the lower energy mass.
For example:
If you drop a grain of sand from 100 mts. high on your head, you won't even feel it.
If you drop a block of 100kg of concrete from 100 mts. high on your head, it will kill you.
Both the grain of sand and the block start with the SAME energy LEVEL (like saying they start with the same temperature level). But the block has WAY more energy MASS that will transfer to you.
So, more density means more total amount of energy available to affect the lower energy mass.
Now, in the corona of the sun, the energy mostly comes from radiation. The radiation density is VERY high.
And the particle density is very low.
That's why simply hiding behind a heat shield (which is a bad name, it's actually a radiation shield) is enough to protect the ship. Because there is no mass around it that carries any energy. And rays only go straight, and don't bend around the shield.
If there were a substantial amount of mass, it would go around the shield and transfer a lot of energy in a very short time, enough to raise the energy level of the ship's mass, to a point were it would break or melt.
There is mass in the corona, but it is very little (low density) so the total amount of energy transferred to the ship is small, and it doesn't raise the ship's energy too much.
@@gdxd7956 Very well said, thanks for the explanation.
Absolutely bonkers! The expertise and sheer hours spent on this mission, and the amount of evolution taken to get to this point, is truly mind-melting!
Could you take a look at the engineering and applications of sodium ion batteries? I’ve been hearing about them for grid storage, but I would love to hear your analysis.
Been hearing about sodium batteries for many years, haven't seen much progress in the news so I'm really interested in seeing what I've been missing. I hope he makes a video on the topic too
For grid storage you have plenty of options for a battery. For example you can simply suspend a weight in the air and move it up and down based on demand and supply. That’s pretty much a gravity battery and would work well for grid storage. We already use pumped hydro as a sort of battery in many places in the world so grid storage isn’t as big of a problem as it seems. The bigger problem is batteries for trucks, or other heavy equipment since you have way more constraints in such an application.

Great video as always. I have just one issue with it: you said the process of changing the altitude of apoapsis or periapsis was named a Hohmann transfer. This is not true. A Hohmann transfer is the combination of two of the maneuvers you described, performed with the goal of elevating or lowering the orbital altitude as a whole. i.e. going from a 450km(Apoapsis) x 400km(Periapsis) orbit to a 1200km x 1100km orbit could be achieved via Hohmann transfer, going from a 450km x 400km orbit to a 450km x 800km orbit could not, as that can be done in one maneuver. The defining characteristic of a Hohmann transfer is that it consists of two maneuvers, done sequentially at opposite points in the orbit, both of which are either prograde or retrograde.
The reason for the corona being so hot is because that's the admin-only barrier, dude. Only reason the parker probe got through was because its buggy entity model abused spaghetti code to glitch past this barrier

All that technology has been demonstrated for decades, and yet we still romanticize the much more technically difficult, energy hungry fusion. Kinda weird.
Everyone's afraid of fission. Meanwhile, they're trying to solve issues with carbon emissions by building inefficient and costly wind and solar farms when the real solution is right in front of their noses. It's like they WANT global warming.

Actually, flames have EXACTLY the same tendency. The center of a flame tends to be far cooler than the tip. Whether the tip is the hottest, or a point between the center and tip, depends on the kind of fire.
But the important part is that fire gets hotter as you move away, much like a star.
In both cases, this is because the chemical reaction progresses as it moves outward.
In the case of the Sun it's most likely due to magnetic fields adding energy to the particles, and since the gas gets more and more tenuous (less dense) the farther you get away from the Sun there's less for them to collide with and lose the energy so they tend to get very high speeds = high temperature.
ERM... except there's no chemical reaction involved in the sun. Combustion only happens in presence of oxygen. These are nuclear reaction, which is a very different thing!
@@Sledr1994 Okay, yes, technically anything involving the nucleus is not chemistry. But a similar event is occurring, where for a while the temperature rises as distance increases in a perfectly reasonable way.
@@Mike__B Yes, my objection is mainly the premise that this is (A) Different than fire and (B) Counterintuitive.
Different process. Unlike in a flame where the heat generating reaction occurs throughout including at the surface, The heat generating reaction in the sun (I.e. fusion) only occurs in the core of the star where the pressure is high enough to overcome Coulomb repulsion. Whatever heats the upper solar atmosphere has to be a different process hence the theories about it being magnetic fields transferring energy.

Very well made. Thank you. I am only bothered by one thing. In my humble opinion, 45 billions are not much for a world changing experiment. (talking about ITER) humans spend multiples of this amount on war. Imagine what we could achieve with so much budget in science and engineering.
ITER's budget was 5 bilion euro when I first read about it in the 2000's. According to wikipedia its starting budget was 6 bil.
As much as I like fusion, I afraid that ITER is more about politics and prestige than about science.
Also remember, that private fusion startups are getting to net positive energy even sooner at a fraction of the cost of ITER! This may seem like an unpopular opinion, but just imagine how much more humankind could have accomplished if so many resources and years of effort had never been siphoned into government war making or government research!
@@johnfisher3380 ITER has itself created new and improved technology, it's not a total loss. Those net positive stories from startups are also still far from close, they're still just nanoseconds of time and unable to sustain it.
ITER with it's large size is theoretically far more capable of sustaining net positive energy. No single private company is able to do this project. That is why tons of companies have been tasked with making the best thing possible for ITER, like the world's most powerful electromagnet for containment. Collaboration like this takes a lot of time and a lot of work to make sure everything works together and is following spec. Some of the parts took over a decade to develop because of the technical complexity and not existing before.

The atmosphere of the Sun being the hottest part could be due to the fact solar flares and radiation are launched up so the atmosphere gets more heating than the "surface" as the heat giving out by the core of the Sun dissipates as it moves up so the "surface" is not actually that hot.
There is a slight error at 3:38. You quote an orbital velocity of 9.2km/s for earth. Whereas, the actual figure is 7.8km/s.
The 9.2km/s figure is, however, often quoted as a rule of thumb the delta v (potential acceleration) needed to reach orbit. With the 1.4km/s discrepancy being due to the inefficiencies due to "gravity loss" (where the rocket is burning fuel to fight gravity rather than accelerate) and atmospheric drag involved in rocket launches.

Because I cant imagine a man made object surviving half a million C temp!
Apart from this, I really enjoyed the video kudos to this channel!
The corona gets up to million or more degrees, but it is not all encompassing in that while the particles in there attain that kind of 'heat', they are relatively few and far between and thus the actual temperature that the probe experiences within the corona is a lot less. Thus, it's all about heat transfer. Liken it to putting your hand in 50-degree (celsius) water--which is hot--and then 50-degree air... the latter feels nowhere near as 'hot'. That heat shield is amazing plus the probe has cooling.
