Hey, just wanted to say, careful with that CO2 number in Problem #2! I fucked up the calculation there, the airplane's CO2 output should be per passenger. So an aircraft would pump out a bit over a 100 tons per transatlantic flight, thus the Starship "only" pumps out around 6 times more CO2 per flight.

That Demon Core story is both really sad an interesting. Fascinating that Slotin would map out his and his colleagues exact positions in order to calculate the radiation they were exposed to. Especially given the fact that immediately after the accident, despite appearing healthy and normal, Slotin knew he was already dead, and had calculated how much time he had left. Fucking terrifying.

That’s not accurate. Tesla: Yes, electric cars have been around for literally 100+ years. But they were ugly, slow and a tiny niche product for a few eco nerds. The car industry was not interested in EVs because they were not profitable. Tesla proved that EVs can be fun, cool, and practical. From an engineering point of view, Tesla actually did “invent” a bunch of things and is one of the most innovative carmakers (e.g. battery tech, software and AI, manufacturing, material science, and more). Btw, Teslas are not “more expensive” (compared to what?), they are one of the safest cars (statistics don’t lie) and certainly not “inefficient” (Teslas have longer range while using smaller batteries than the competition….that’s the opposite of inefficient). SpaceX: Falcon 9 is the first re-usable VTOL rocket. Nobody else can do this yet - and SpaceX has been doing it on a routine basis for years now. Pretty impressive, especially considering the size and young age of the company. Oh, and their “price to orbit” is FAR cheaper than the US & international competition. Starship uses a buttload if new tech and approaches that have never been used before - no idea how anyone could claim “it already exists, is more expensive, inefficient and hyped up” in regards to SpaceX…it’s literally the exact opposite.

At the time the airplane was invented people most definitely *did not* say that flying was impossible because 1) hot air balloons and airships were already a thing, and 2) there were hundreds of people experimenting and trying to create the airplane at the time. There was even airclubs in most of the world's biggest cities, and the airclub of Paris was the one that saw the first real airplane (that was capable of taking flight on its own, it didn't have to be thrown on the sky like the one the Wright brothers made) take off for the first time, made by a Brazilian named Santos Dumont.

What I'm saying is that their airplane might not have had the capacity of taking off before Santos Dumont's flight, not that they didn't have anything. Santos Dumont's airplane was actually his 15th flying machine, and many of the previous ones were shaped pretty similar to that one, and could even fly for a little bit, but they had to be catapulted. Many inventors at the time already had built machines that could plane for a bit after being catapulted, the difference of that to a real airplane is the capacity of taking-off on their own, and that is why a lot of people across the world doubt the Wright Brothers. They can't prove their plane was able to take-off before Santos Dumont's airplane first took-off. The US already has many accomplishments, let other countries get theirs recognised too.

The reason we invested so heavily in light water reactors and not molten salt thorium reactors is because light water reactors are nuclear bomb material generators.

[@seneca983]

I'm not sure I buy that. Firstly, commercial reactors are not bomb material generators because they use high burnup. Secondly, the reason why some alternative reactor types like thorium reactors or fast breeders were considered was the perceived limitedness of uranium deposits. However, because of *arms* *reduction* nuclear arms production no longer competes for the fuel on the same scale and many decommissioned weapons have been turned into commercial fuel. Also, new deposits have been discovered. Because of these factors uranium is cheap and investing into alternative reactor types has not appeared to make commercial sense.

[@andrewbrown1454]

I read an article over a decade ago where it detailed out interstellar travel propulsion methods. One was regularly dropping nuclear fission bombs in a propulsion cone behind the spacecraft.

[@Paraselene_Tao]

Around 10:50, yes. If I'm not mistaken astronauts experience about 3g for about 2.5 minutes going up and going down. That's a total of about 5 to 6 minutes of about 3g forces. It's a stressful situation and for many people probably an out-of-body experience due to the high amount of pain and stress. It would help to take halcyon or klonopin 90 minutes before the 3g experience.

[@sardoniclaugh9646]

3g is not a big deal. Roller coaster rides push up to 6 g and usually above 4 g. Yes it's for a shorter amount of time but kids ride those for God's sake. With a g suit almost anyone can handle 3 g for a couple of minutes.

[@sardoniclaugh9646]

Also there's G forces and G forces. In high speed high angle of attack combat aircraft maneuvers the G load that causes loss of consciousness is -Gz.Transversal G forces in case of rocket takeoffs in particular +Gx are much easier on the human body. In fact vision is not affected even at exposures of upwards to +13Gx and loads of +25Gx have resulted in no permanent health damage. Source - "Effects of Acceleration on Human Performance and Physiology, with Special Reference to Transverse G." USAF School of Aerospace Medicine, Aerospace Medical Division (AFSC), 1968.

[@Paraselene_Tao]

I will read more about it later-particularly your point about plus or minus of the G in x, y, z axes. Thanks.

[@Paraselene_Tao]

I will look at the paper you've cited, and much more at a later time. Have you considered the difference between a few seconds of peak 6 G on any axis and sustained 3 G on any axis? The roller coaster rides reach up to 6 G for possibly a few seconds (maybe 5 seconds tops in a spinning, accelerating, downward spiral-this might cause significant G forces in all 3 axes during acceleration). I understand that fighter jet pilot maneuvers reach about 9 G for about 15 seconds (I'm sorry I don't know exactly which aerial maneuvers require this G force, but I will be happy to learn the common data on this); and finally, a space shuttle accelerates at 3 G for 150 seconds up and down (I can't say for sure which axis the force is upon the human body because on the way up, the astronaut might being sitting in many possible orientations--and also on the way down the astronaut can be sitting in many possible orientations). The impulse in each case done on the human body is: roller coaster 30 G force seconds, jet pilot 135 G force seconds, and astronaut 450 G force seconds. These calculations I got from simply multiplying the G force and the time of each situation. I do not believe this is a totally appropriate way to compare them because it's missing the axis details you pointed out, but I think it puts in perspective the Impulse (force multiplied by time) on the human body. I am not any kind of expert on this topic and I would be happy to look at the obversable data, and learn the concepts behind the topic. I really need to complete several physics courses to grasp these ideas. I appreciate your help. Edited: I changed the 3 G roller coaster ride to 6 G to align with your comment.

[@sardoniclaugh9646]

@@Paraselene_Tao Read the paper. Also think about the physics of the human body. Vertical G forces are much more disruptive, the blood is pushed down or up in the case of what pilots call negative G's causing massive stress to the cardiovascular system and in the case of downward G's (-Gz) deprive the brain of oxygen causing subjects to black out. Also negative G's push the contents of your stomach upwards which can result in very unpleasant consequences (projectile vomiting isn't fun). Transversal G forces by comparison don't do any of that. Very high loads can cause lung compression, basically you feel like a big rock is placed on your chest which is basically what is happening except the rock is your own pectoral muscles and rib cage. Astronauts are seated facing upwards so the G load at takeoff is +Gx. Loads of +2 to +4Gx have been shown to not affect the performance of pilots even at exposures of 10 minutes and more. These are trained fit men, admittedly, but they experienced no problems whatsoever. They didn't experience any loss of visual acuity even at loads up to +13Gx. For comparison -13Gz will kill most humans in a matter of seconds let alone affect their vision. The maximum transversal loads tested in this study was +25Gx. That's gigantic and yet no permanent health damage was observed. It's quite clear transversal G's are at least one order of magnitude more tolerable than vertical G's.

Rocket fuel can be made of liquid oxygen and hydrogen so it is not necessarily fossil fuel

[@prometheus3498]

I wish Vaush would link to the original video in the description, its just good practice and ensures that the original video maximizes view count.

[@sethdrake7551]

18:30 responding to vaush's question here: theres more or less two options for nuclear rocket engines 1. Nuclear Thermal Rockets (NTRs) 2. Orion drives nuclear thermal rockets use the heat of a nuclear reactor to heat up fuel really hot and you run usually liquid hydrogen through it and it produces moderate to high thrust at about twice the efficiency of chemical rockets (and you irradiate everything near the exhaust usually). these can be designed to have comparable thrust to chem rockets but that takes some doing orion drives/orion engines use the explosive force of (many small) nuclear bombs pushing against a large armor plate on the back of the rocket to propel the ship forward, if you use hydrogen bombs you basically get the most scuffed fusion engine imaginable, but it works, and theyre actually pretty good at what they do but in general the reason we dont use either of these yet is mostly because if you accedentally lets say, have a RUD (rapid unscheduled disassembly) halfway up through the atmosphere, youre going to end up with nuclear fallout going absolutely everywhere around your launch site and onto anything downwind of it

[@nargacuga05]

I remember designing safety systems for our hyper loop project and we kept our g ratings below 2G unless that was literally impossible

[@MichaelUrocyon]

I would absolutely watch a stream where Vaush just watches science videos and says that's so fucked occasionally. Imagine going down the list of broken arrow incidents.

[@cannibalmonkey]

As someone that was a part of the nuclear powered navy, his opening discussion hurt my soul.

[@Disthron]

41:43 If I'm not mistaken, It would emit a ton of radiation, melt and explode in the same way throwing water into oil explodes. It's not like a nuclear explosion.

[@Stryqwills]

Yeah that fuel weight problem is something that I dealt with in Kerbal space program. Basically the best way to do it would be to actually calculate exactly how much time of burn I would need and only fill the tank up enough for that amount of burn. Of course you have to calculate for the fact that the tank gets lighter as you burn, but basically initially the hardest part is getting it off the ground.

[@sethbennedetti753]

Watching Vaush learn about the nuclear testing accidents is amazing. If you did some more content like this i would not be mad.

[@melineeluna]

The Las Vegas loop is a great thing laugh at. A 3/4 mile, 3 station taxi tunnel system can't reach much speed, and the exits can't be super far away. The full-scale concept is way more terrifying. The loop (aka drivable Tesla Tube) is the most dangerous, easiest to sabotage transport system I can think of. It's as vulnerable as a train or subway, but is also less flexible, making it harder to reroute traffic when one tunnel is out of service. Anyone who wants to could shut down the loop, as long as they get in there. As reliability goes, there are just more points of failure when you add more vehicles. And when something goes wrong, there might not even be enough space to open the doors to get out of the car, not to mention how hard it will be to get past all the other cars on the way to an exit. If they ever get to build a full-sized system without complying with the safety standards for underground highways, catastrophe is inevitable. I'm not encouraging sabotage here. I'm just pointing out that any problem that occurs during normal operation can have enormous consequences that affect the entire system, and will probably be a danger to the people in the system. A blown out tire at 150 mph will probably be bad enough to get people stuck in there for hours. An actual crash could turn a tunnel into a dead end in no time. A lithium fire will cause people to get stuck, with a wall of flames an toxic gases on one side, and an ever growing line of Teslas on the other. If Musk's lobbyists ever gets approval for a high-speed car tunnel that doesn't have to comply with NFPA 502, I advise you to never enter such a tunnel.

[@riesenfliegefly7139]

To answer your original question you asked at 18:10 To understand the comparison you have to understand how propulsion works. If you want to propel stuff in one direction, you have to propel other stuff into the other direction. (Every action has a reaction.) In this case were talking about momentum, which is speed x mass (aka propelled stuff). In a rocket you have fuel which explodes. This explosion will propel the fuel leftover gases (like CO2) out of the rocket. It has a low mass, but a lot of speed. The momentum of the gases will propel the rocket in the other direction (hopefully upwards). A submarine however uses a propeller which turns to propel water, instead of explosion gases. The nuclear plant in a submarine is used to fuel this motor, which means the nuclear energy isnt directly causing to acceleration, unlike in a rocket, were the exploding fuel directly causes the acceleration.

[@AlexSciChannel]

Un Dunning Kreugerify Vaush. Thank you

[@QuantumPineapple]

Vaush should do more science/tech related stuff it's kinda interesting when he discusses it.

[@ccole1255]

The Demon Core guy killed everybody else in the room too... 4-5 people were there watching him pull his little stunt

[@seneca983]

"The Demon Core guy killed everybody else in the room too" No, he didn't. All the others lived decades after except one guy who died 4 years later in the Korean War. They did receive substantial amounts of radiation though.

[@bryanmaine]

There's a design out there for creating giant cylinders in the ground that are essentially space cannons. Nuke goes off at the bottom, projectile heads to the stratosphere

[@sanitytheorist8221]

Thorium reactors have been made on a small scale, I'm curious whether or not those could be adapted for rocket launches.

[@rowbot5555]

You'd need the whole payload of a super heavy life vehicle just to get the reactor module up into space, so you'd have to assemble it orbitally like with the ISS

[@ArchmageIlmryn]

You probably could build an orbit-capable nuclear thermal rocket (which essentially works by using a nuclear reactor to heat some sort of reaction mass and then spewing the hot mass out the back). The main problem is that you'd be spewing radioactive gas everywhere. Main reason nuclear propulsion is seen as an "assemble in orbit only" thing is because you don't want to spew radioactive exhaust everywhere while on Earth.

[@ariandynas]

Part of the issue with what makes a Thorium reactor safe is that it needs a lot of space. When the Thorium-salt solution reaches a temperature capable of damaging the reactor it melts through a plug at the reactor's bottom with a lower melting point, draining it into a large basin where it cools - it can do this because unlike modern Uranium-Plutonium reactors it doesn't need to be kept under pressure, or at temperatures nearly as high. And because the Thorium needs to be kept at a high temperature in order to create fission reactions, it actually stops as soon as it begins to cool, effectively self-regulating, and preventing a meltdown.

[@superfluousnscrupulous9458]

I'm starting to get the idea that Elon Musk doesn't actually know how to solve the problems he sets out to fix

[@UncleJemima]

"problems"

[@JonReams]

One of the biggest failings of the Concord at supersonic transports in general is the cost. While the Concord did suffer a catastrophic failure that led to it's ultimate retirement it was only the final straw. Concord flights were generally loss leaders. Operating and maintenance costs ate up the ticket cost. There was still profit, but it was operating on a razors edge

[@theone4782]

18:47 the Russians had a nuclear plane prototype and the US also developed a nuclear jet engine, there is even footage of it on the internet wich is extremly cool. And there was also project orion were the wanted to use nuclear bombs to shoot stuff into space.

[@mt.penguinmonster4144]

I should probably make a playlist of these segments where chat gets increasingly anxious

[@ArchmageIlmryn]

You should have looked up nuclear pulse propulsion as well - it's a rocket concept that literally works by throwing nuclear bombs out the back (and which in the 50s was seriously considered as a ground-to-orbit vehicle, scale models (using regular explosives) were even tested). It's also one of the most realistic designs for building a ship capable of interstellar travel with today's technology.

[@tylergodfrey5064]

20:38 The meteor that killed the dinosaurs triggers a chain reaction that blows the entire planet apart.

[@Terminalsanity]

Like most of Elon's projects there's like 1/2 of a good idea buried under a ton BS hype and overly complicated and wholly impractical crap. Barge based rocket platforms would be a theoretically great achievement because you could cluster them around the equator reducing the fuel needs to get rockets into orbit while reducing the risk to major population centers in the event of an accident. But loading up people into a massive reusable rocket for travel is so massively cost prohibitive and wasteful it staggers the mind. Like seriously a hypersonic airliner or rocket plane like the shuttle is far more feasible but as the concord proved there's very a narrow margin where you can have only so many people be willing to pay such a steep price to cut travel time. More to the point the time to embark and debark from the yacht to get to the from shore to the barge and to the barge to the shore is going eat so much time you're again better sticking to a hypersonic airliner or rocket plane ever if its going half as fast as these rockets.

[@sardoniclaugh9646]

Why do you comment on things you clearly don't understand. Rocket planes or any other type of transport that doesn't leave the earth's atmosphere cannot achieve anything above a fraction of the speed ICBM's are capable of. The SR-71 Blackbird pushed atmospheric flight to it's absolute limits with it's Mach 3 cruising speeds.

[@Terminalsanity]

@@sardoniclaugh9646 You do know we used to send a rocket plane into orbit that achieved those speeds all the time decades ago or did you not realize that's what the Space Shuttle was? And like Vaush literally pointed out in the video a hypersonic jet (might want to google the term scramjet BTW)going just quarter as fast will get people their destination in less time because they won't have to get on a boat to get to the plane and all at a fraction of the cost and fuel usage. Look buddy, you literally have not a leg to stand on to tell anyone what they don't understand about the subject at hand, let alone an Air force veteran like myself. I suggest check your misplaced hero worship of just another over-hyped and overrated richman's son who takes credit for his employee's innovations while talking heaps of pseudo intellectual BS and trade up for some critical thinking and informed opinions.

[@SoSoKayla]

Using rockets, how would you get shit to and from barge based rocket platforms on the equator to anywhere other than to other barge based rocket platforms on the equator? The same way you'd get shit to and from barge based rocket platforms on the equator to anywhere, including other barge based rocket platforms, not using rockets. Even your example, even on a theoretical level, would simply be taking already existing achievements in rocketry and aeronautics in order to provide an unnecessary solution to a non-existent problem. That's only a "great" achievement in the ridiculous scope and scale of one's commitment to an extremely niche hobby, nothing more.

[@obliviousotterI]

@@sardoniclaugh9646 Suprisingly enough the speed of a journey is reliant on much more than how fast the vehicle can go. If you had to walk 25 miles to an airport then fly 100 miles, then walk another 25 miles to your destination, driving would be to faster option, even if planes go faster. And as you would have to boat out to these landing barges, the analogy fits.

[@Terminalsanity]

@@SoSoKayla You seems to have misunderstand what I was proposing. I'm not talking about staging barge based rocket platforms around the equator for the purposes of a creating a transportation system but launching standard commercial satellites and the like into space to reduce fuel costs and the chances of overland rocket accidents The closer to the equator you launch a rocket from the less energy it takes to a rocket into space but most of the land on the equator is remote and underdeveloped so since you'd have ship in all your support and equipment in anyway and build up a ton of infrastructure a sea based barge rocket platform makes a lot sense.

[@dyssonpitcher612]

I feel like Space Elevators would be required for an idea like this. It would entirely eliminate the need to escape Earth's gravity.

[@skyty0]

I feel like everyone is glossing over the conversation those two Tesla bros we're having in the tunnel. "It's fun to just go around." Like is this what rich people do for fun lmao

[@PCr4zy]

There is so much to add to this vod: 1) 7:30 ... full throttle take-off in standard aircraft it 0.3g and it enough to strap you into your seat ... 3g would be melting for not fit people. 2) 18:44 ... we actaully DO have prototypes of nuclear rocket engine as you describe. The problem is THE EXHAUST of said engine is also radioactive af. So basically taking of 20miles of a coastal-city will give everyone in said city cancer. Not mentioning wind would carry and spread the uncontained exhaust all around world. 3) 20:30 ... there actaully are Natural Nuclear Reactors, aka. caves that are enriched just enough to sustain chain reaction. According to quick google search, they are just highly radioactive (cause decay products) and warm (or used to be warm) caves. 4) 35:50 ... Understand the sentiment "that dude is an idiot", other way to look at him is 'that dude is groundbreaking scientist tryin to understand groundbreaking science that is so new nobody understood it yet'. YEP Sigma af. good question is if the demon core would actually just melt (meaning it would prolly melt thru the bottom half of the neutron reflector and prolly all floors and ceiling of that buildings, not unlike the elephants foot) or it would actually reach a point of fizzle explosion (severity here also vary from just knocking the top off to few kg of TNT/C4).

[@sardoniclaugh9646]

You don't know shit. Transversal +Gx is very tolerable compared to -Gz. -9Gz is about as much as trained pilots can handle but they can pull upwards of 13+Gx without even losing visual acuity and loads of +25Gx result in no permanent damage. +4Gx is not a big deal it's uncomfortable but that's about it.

He’s like the only online “skeptic” who held true to his name and didn’t become a psycho (though his channel does post date the rise and chud-ification of online skeptics). Heck, if it wasn’t for his part in creating the anti-SJW period (and the fact that I severely doubt his views on it have changed) I’d recommend Thunderf00t ever since he stopped embarrassing himself with his political content. As his smarmy, condescending attitude is much better served going after charlatans like Musk rather than female game critics.

Fun fact, during the earliest years of earth's history (Hadean period iirc), there was a time when a metric fuckton of natural nuclear explosions occurred, with a much higher payload than the bombs dropped on hiroshima and nagasaki. Edit: I looked it up, it was 1.7 billion years ago

A common defense of the Loop is "at least Elon is revolutionizing tunnel boring technology; making it cheaper and faster." In reality, the machine the Boring Company uses is basically the same one that's been used for decades. What Musk did was he made his tunnels narrow so the machine would be smaller, cost less to operate, and tunnel faster. This is why the concept for the Loop kept changing. The original CGI animation had massive tunnels that could fit multiple lanes of traffic. The prototype had tunnels large enough for "pods" (small busses). The final design is this tiny tube that can fit one Tesla sedan at a time. The point was always to just to make his system cheaper to build so he could undercut any competing bids. The loop has a far lower capacity, is less safe, and is more expensive to maintain than an underground rail system, but so long as his bid is low he can swindle cities out of their money.
