Oh sure....the great Duct Tape That when you want it to stick it doesn't and when you want to remove it it instantly becomes the rubber version of Adamantium.....
Honestly loving the direction this channel is taking, seems like linus is less business stressed and more focused on making entertaining content that he himself would like to see.
True...but linus needs to be a lil careful. Seems this one might of been a little too dangerous for fun content on RUclips. Like ngl, I'd hate to hear one day Linus took a stray screw to the neck for a video.
That fan scared me, both the electrical power going into it and what it does with airflow. At least it was presented in a fun cheerful way, so it was obvious from the start nothing went seriously wrong with any of the people present. Was glad to see the electrical part being handled fairly sensible short of doing the filming at a place with the right mains being available. But this fan duct being apparently unconstricted on both the intake and exhaust was mildly concerning to say the least even at "low" power up to 10%. If any object with some density got sucked into it somehow (entirely possible with the open doors even when taking all precautions in the room) could be pulled through and launched as a projectile or shredded into dust. Or worse that impact could shatter the fan blades with all kinds of possible outcomes. Small bits could easily come loose inside the case too and make it out through a gap, but the video would probably be less fun when filming it from a distance always with a protective thing between the fan/computer and people while operating at high power. I also don't know if the exterior of the fan is considered to be able to contain a catastrophic failure of a fan blade internally at maximum power, shrapnel of the spinning blades going sideways through the exterior are scarily familiar. Even if it can contain it it'd still make a mess in the room and being so close might not be wise. More than a few airline incidents happened because the engines couldn't contain an internal failure, either from normal wear without timely inspection or ingesting objects (typically birds but stranger things have happened). Glad it went well and I did enjoy watching the video, but I do know I wouldn't want to be so up close or in the airstream myself if I was there. Would definitely want to play with the fan though and see what it does to objects various objects.
11:00 it's duck tape named after "duck cloth", which was used for it, with adhesive backing added. The name duct tape is just because some people briefly used it for duct work even though it's not appropriate for the application. For duct work you technically use flue tape, usually aluminum backed.
Luke needs to see the drop at 11:27, It was 100% staged. The side panel was never ontop of the computer, then it cuts and it gets ontop just for the drop!!! Luke needs to watch this
I just love the combination of Kyle and Alex in part because of their knowledge (especially Kyle I think) but also because of their combined efforts to tame Linus.
I love every engineer you hire, they just all have as Kyle so elegantly puts it, "We've thought about this! Where's the hammer!?" energy, and I'm here for it.
Linus: "i want to toy around with a giant industrial grade 60 horsepower fan, how do i write it off as business expense?" Alex: "we can attach it to a computer, run p95 for 2 minutes and make it a video" Linus: "this is why you're the lead engineer here"
As a hobbyist and out of curiosity I once took a blender motor and put a fan blade from a space heater on it, put a metal coffee can around it and used it to clear out my workshop because it was 100x more powerful than a leaf blower. I used a basic dimmer switch for a ceiling fan to control it.
@@Glade4 Simple, lithium fires are very hard to put out and very intense, you don't want that anywhere inside the building or it can burn down the place before the fire department has a chance to get there. (Not to mention all the toxic fumes it creates.) That is why they even took out the battery pack outside, the faster you discharge those batteries the more heat they generate and they got dangerously hot. The biggest problem is that they can undergo thermal runaway (Basically they get beyond a certain temperature where it will keep getting hotter and hotter even if you aren't doing anything with it until it catches fire or explodes. Can't use water to put it out.)
@@alexisrivera200xable lithium fire are not hard to put out, they are almost impossible to put out, and if you do manage to stop the flames they can reignite for up to 60 days
Too much back pressure in the case. If they were to cut off the back completely so that the air could go right through it would probably have ripped off the cpu cooler at least. They should do this again with an open air "case".
I have a feeling that was because the air simply wasn't getting out of the case fast enough, so it created a back pressure and wasn't nearly as hardcore as when they took the case away
The fact that anything could loosen and fly off at high speeds as a very dangerous projectile and Linus is sticking his head right behind the fan all the time is mesmerizing. 10/10

For videos like this, you should get one of those giant, clear, bulletproof shields like they used on Mythbusters. If something got sucked in that fan and shot out erratically or one of the batteries go boom, you would at least be safe from shrapnel and such. That fan has crazy power!
Sorta. The wall socket ratings are extremely conservative because it's expected that the wires in the wall will be there for 50+ years and never overheat. Whereas these batteries are overheating with air cooling... Just yesterday I saw an HVAC recommended a 40A breaker, but draws 135A for ~1second while starting the compressor. With all that said, those batteries do have pretty insane power.
@@wetmelon Similarly, I've wired up massive stud welders at a steel beam plant that pull 300 amps @ 600v 3ph for 1.25 seconds, with 6 seconds in between welds. The machine factory installed feed cable is only 6 awg copper and it handles it fine due to the duty cycle.
@@gerald8289 welders also have voltage converting transformers inside to up the amperage and lower voltage. 6 awg is easily enough to power that, not saying the whole thing is nothing because its not, its crazy lol
"Don't do this at home!". Kind of reminds me of how they kept saying that on Mythbusters when they were blowing up cement trucks with tons and tons of high explosives or building slingshots taller than buildings. I think the people who can do this at home are doing it regardless of what you're telling them and everyone else couldn't even if they wanted to.
When your highly trained engineers that are kinda crazy are scared about handling the controller of this new interesting machine... well, is fair to be concerned.
I work in the trucking industry and all the sensors on vehicles are pwm. I've always had a pretty good grasp of it but explaining it to mechanics who barely understand how basic 12v systems work is like explaining rocket science.
I can assure you that out of all 15 million subscribers (at the time of writing) and over 1M viewers, there definitely have to be some with enough disposable income to just buy this fan to keep around the house. And some will be crazy enough to do it.
@@techwith_tjyeah made me laugh that they edited Spider-Man over him when he was sideways but not when he’s literally looking at the other camera man 😂
Kyle + Alex = Amazing Duo. What is better than one engineer doing janky stuff for a crazy boss that like that stuff. Another engineer that knows what the other don't so they can tackle even more crazy things xD
This fan that was in the video wasn’t even a tunnel fan it’s even more excessive than one of those. The edf used in the video was actually made for small aircraft.
Its amazing that there are multiple engineers doing an incredible over complicated and expensive circuit that only runs for a couple minutes when they could have simply rent a tri phase AC generator and run the thing at max power for whatever time you want.
Hey Linus and team, I work for a company in the UK that make huge industrial fans (Woods Air Movement) I could probably get you guys hooked up with a 2 metre diameter fan if you ever wanted to go crazy!
They said that there was too much positive pressure in the case due to lack of throughput, so if the side panel shattered, it would've just blown out the side, no?
To be fair they did look actually cautious and concerned this time. THAT shows you how dangerous the tools they were playing with this time and that they can be serious when required.
They blurred the new guy’s face when he caught the pc glass panel bc he’s on his probationary period, and then didn’t bother blurring him for the rest of the video. Does that mean catching things that Linus drops automatically brings you out of the probationary period?
I found it funny how you can just tell Kyle was being serious when he was saying you NEED to be careful with this. And Linus wasn't taking it serious to begin with until he's just like oh ok then
It just blows my mind they don't have 3 phase outlet there. I mean it's also problem of 120V instead if 230V but the fact they convert BATTERY!!! DC to 3 phase AC is mental and sorry if that is situation of grid in Canada, holly molly how do you even exist. I have 3 phase 64A main circuit breaker at home at 400V. This video insane and shouldn't even exist.
@@jamessatler5461 They do but I don't know how expensive or how long it would take to have it installed. Different places have different legal requirements and permits after all. Unless Linus is planning to use a lot of machinery in the future that would need a 3 phase outlet, this probably isn't worth doing. But I thought they did end up buying all that machinery awhile back, presumably for the labs thing. I don't know how much power that equipment draws though. I don't really watch LTT so I don't know how they set all this up. If they do have equipment that use 3 phase power that means they probably already have a phase-converter. Linus did mention near the beginning of the video that the transformer for their building couldn't handle the power draw required for this experiment though. Would be nice if my home had a 3 phase circuit breaker.
Just to let you guys know, your earplugs are not properly inserted. Make sure to roll the earplug up into a small, thin "snake" with your fingers. Pull the top of your ear up and back with your opposite hand to straighten out your ear canal and then hold the earplug in with your finger until it expands to fill the ear canal.
This was like the last thing I expected to see in the comments section but a long lost question I've always had but never bothered to look up has been finally answered, so thank you
Yep, it doesn't block the full frequency range like that. I worked in an industrial factory and we had to be shown that during orientation. I also learned that I could wet the tip of the plug and it will fully insert easily. I still wear them every night when I sleep as I live in a busy semi truck route. If they were only half inserted they would fall out.
Over the ear ones are better. No matter what I do my ears spit out the foam ones. It just isn't worth the risk of suddenly loosing hearing protection. And over the ear ones aren't that expensive.
I love how the editors went to the effort of hiding the new guys head when they caught the panel, but completely neglected to even attempt to do so when the camera pans over them after the turbine is powered on with the computer attached to it (11:30, 12:50)
See I was thinking that but they didn’t necessarily say he was on probation and if you noticed they made him look like Spider-Man after making that catch… most likely a goof still tho lol
The most dangerous thing was the intake and I'm not even sure they have realized it. Blowing out this much air means the suction power is equally strong. And yes, this is literally an electric jet engine... I'm quite sure it was designed with airplanes in mind.
Yeah I was thinkitof that as well - it could easily suck something in and make all go haywire - I work with MRI and and it's the same, everything is fine until it isn't ....
You gotta get those mythbusters bulletproof glass shields, this is crazy dangerous. If something got sucked into that thing (very possible) and shattered parts of the blades out the back at full speed someone could get really hurt...
@@compaqdeskpro5770That fan was perfectly capable of grabbing itself a carrot or pink wig @100A. They can be thankful that it wasn't feeling particularly hungry that day.
The question is. Is it a concerning thing that I've said those exact words to my boss in a completely different context? And somehow yes I am in the works to becoming an electrical engineer
This was legitimately terrifying to watch. I thought Linus was going to have the pc fly straight into his face. Linus Death Tips doesn't have the same ring!
I love that "new guy" is face blocked out for catching the case panel, but when they first spin it up he's just there for quite awhile in the background. Hi new guy!
as a leyman in aeronautics, what do you mean by prop circle ? do you mean the width at which the prop projects its output ? disregarding my knowledge of aircraft, i still know this video was a dangerous game.
@@dominickkramer6469 think of an area around the blades of the fan, propeller, or jet engine, as a giant circle. As they’re spinning at high speeds, if any single blade were to be unbalanced, they could break and shoot out in any direction of that circle. Aircraft have a line marked on the fuselage to show where not to be if this happens. In the video, they were standing directly left or right of the fan in the area of that circle.
As it's it's ducted design, I would imagine (and hope) that the casing is designed to contain shrapnel in the case of a blade-off, in the same way as the nacelle of a jet engine is designed and tested to.
@@chrisburn7178 Nacelle is designed to hold it, yeah. But it isn't strong enough to come through it intact. The nacelle is designed to bleed off energy by blowing apart tossing lower velocity shrapnel everywhere. The underside of the wing and passenger compartment that are inside the prop circle are reinforced to take not just those hits, but the full hit of a blade coming off and hitting the plane. The idea is that once the shroud violently deconstructs itself from the first indecent a second blade could break off afterwards before the engine is shutdown. So the wing and body need to be strong enough to take that second hit. Those areas are actually the strongest on any plane. When dealing with those types of forces it's just stupid to trust anything to work without a backup.
Them playing with the fan reminds me of the time when i was mech infantry. We were getting ready for a training mission and got rained on while prepping our bradley fight vehicles, I was soaked. The tankers next to us fired up the jet engines in their abrams, and I had the brilliant idea of standing behind the rear of the vehicle to dry off. I lasted maybe 10 seconds, behind what felt like 1000 hair dryers on full blast before running back to my gunner seat. I was warm, dry (and inturn happy), and had a new respect for their engines.
My close friend was in the army and drove a Bradley and he has similar stories sanding behind the abrams when he was stationed in Europe during the winters lol, god bless gas turbines
the actual fear most the guys had given the wild things they have done before and being profesionals actually show how dangerous this project actually is
I'm fairly comfortable around high power battery packs, if the BMS consisted of a temperature reading and Linus not going full tilt I'd be running for the hills.
@@michaeltodd17his concerning level adapts to what he's being told by the engineers I think, so when the engineers are at an alarm level six out of 10 he is like a three out of 10, but now he was actually at 6 or so, and the engineers were probably higher. So his comment was not that wrong I think, Linus is definitely the translation of how scary it is, Even though he might not understand everything Not sure if I was able to point out what I wanted to say, But hopefully you get the gist
Linus, I have a proposition for you: Let Alex and that other dude be The Mad Scientist brothers and have a series of them doing crazy stuff like this AND blowing stuff up. 😂 My promise? I'll watch every second of it 😋
There was already a show like that called Mythbusters in case you forgot or didn't know. Adam and Jaimie blew up a fair amount of stuff back in their days...
@@lenardz Because all are they gonna bust is all the tech they put their hands on? xD Also, it'll be kind of a sausage party since they lack a female engineer, in fact they don't need to do a rip off show, they're already fine with LTT's wacky mad scientist/engineer projects imo.
Linus holding the remote away so they don't take it from him is so funny, looks like a little kid recognizing that his mom is about to take the controller away, trying to get some time to promise he'll do homework in 20 minutes.
Watching Linus stick his head behind the computer with a GLASS side panel really gave me anxiety. If the negative air pressure shattered the glass while his head was back there this would have been a very different kind of video. I don't think the tape would have done much.
really cool video, its crazy that sony managed to get one of those fans into every ps4. the jet engines ramping up really brings back some good memories

It's honestly pretty wild to me that those 6 battery packs put out more power than an industrial wall socket can
Sorta. The wall socket ratings are extremely conservative because it's expected that the wires in the wall will be there for 50+ years and never overheat. Whereas these batteries are overheating with air cooling... Just yesterday I saw an HVAC recommended a 40A breaker, but draws 135A for ~1second while starting the compressor.
With all that said, those batteries do have pretty insane power.
@@wetmelon Similarly, I've wired up massive stud welders at a steel beam plant that pull 300 amps @ 600v 3ph for 1.25 seconds, with 6 seconds in between welds. The machine factory installed feed cable is only 6 awg copper and it handles it fine due to the duty cycle.
Chemistry is wild, man.
@@wetmelon the 135 is the inrush current, pretty much all motors will do that.
@@gerald8289 welders also have voltage converting transformers inside to up the amperage and lower voltage. 6 awg is easily enough to power that, not saying the whole thing is nothing because its not, its crazy lol
"Don't do this at home!". Kind of reminds me of how they kept saying that on Mythbusters when they were blowing up cement trucks with tons and tons of high explosives or building slingshots taller than buildings. I think the people who can do this at home are doing it regardless of what you're telling them and everyone else couldn't even if they wanted to.

That explanation of pulse-width modulation was pretty great. I've had a shaky understanding for years, and something snapped into focus.
I work in the trucking industry and all the sensors on vehicles are pwm. I've always had a pretty good grasp of it but explaining it to mechanics who barely understand how basic 12v systems work is like explaining rocket science.
If you've coded microcontroller, it's probably the one of things you learn in the first hour.

I can assure you that out of all 15 million subscribers (at the time of writing) and over 1M viewers, there definitely have to be some with enough disposable income to just buy this fan to keep around the house. And some will be crazy enough to do it.

"60hp fan"
It's not technically a fan, eh. It's an engine and it's rated for thrust, not airflow.

I know the PC was tied down securely, but if that glass had shattered while Linus was downstream, he would have been in for a very bad day.
That's worse than a shotgun to the face
Yeah, with that much throughput, it would have been better to just remove the side panel.
ohohoh i didnt think of that
They said that there was too much positive pressure in the case due to lack of throughput, so if the side panel shattered, it would've just blown out the side, no?
Linus: "I have safety glasses on. Surely this will protect me from a double hurricane."

To be fair they did look actually cautious and concerned this time. THAT shows you how dangerous the tools they were playing with this time and that they can be serious when required.
They blurred the new guy’s face when he caught the pc glass panel bc he’s on his probationary period, and then didn’t bother blurring him for the rest of the video. Does that mean catching things that Linus drops automatically brings you out of the probationary period?
Probably yeah.
They put spiderman on his face cause he caught the panel, not to hide his identity.

Yeah, and he just stands there... some tiny loose bit and bam, right into his face
This legitimately seems like a video that could have ended very differently had some minor thing gone wrong.
It just blows my mind they don't have 3 phase outlet there. I mean it's also problem of 120V instead if 230V but the fact they convert BATTERY!!! DC to 3 phase AC is mental and sorry if that is situation of grid in Canada, holly molly how do you even exist. I have 3 phase 64A main circuit breaker at home at 400V. This video insane and shouldn't even exist.
@@jamessatler5461 They do but I don't know how expensive or how long it would take to have it installed. Different places have different legal requirements and permits after all. Unless Linus is planning to use a lot of machinery in the future that would need a 3 phase outlet, this probably isn't worth doing. But I thought they did end up buying all that machinery awhile back, presumably for the labs thing. I don't know how much power that equipment draws though. I don't really watch LTT so I don't know how they set all this up. If they do have equipment that use 3 phase power that means they probably already have a phase-converter. Linus did mention near the beginning of the video that the transformer for their building couldn't handle the power draw required for this experiment though.
Would be nice if my home had a 3 phase circuit breaker.
Just to let you guys know, your earplugs are not properly inserted. Make sure to roll the earplug up into a small, thin "snake" with your fingers. Pull the top of your ear up and back with your opposite hand to straighten out your ear canal and then hold the earplug in with your finger until it expands to fill the ear canal.
This was like the last thing I expected to see in the comments section but a long lost question I've always had but never bothered to look up has been finally answered, so thank you
Yep, it doesn't block the full frequency range like that. I worked in an industrial factory and we had to be shown that during orientation. I also learned that I could wet the tip of the plug and it will fully insert easily. I still wear them every night when I sleep as I live in a busy semi truck route. If they were only half inserted they would fall out.
@@andrewt9204 same i got used to it. sleep is amazing with them.
I would be getting the over the ear ones aswell for that noise level.
Over the ear ones are better. No matter what I do my ears spit out the foam ones. It just isn't worth the risk of suddenly loosing hearing protection. And over the ear ones aren't that expensive.
'' We've thought about this, where's the hammer! '' probably the best quote on this episode.
I love how the editors went to the effort of hiding the new guys head when they caught the panel, but completely neglected to even attempt to do so when the camera pans over them after the turbine is powered on with the computer attached to it (11:30, 12:50)
I had to scroll a little further than I thought I would have to just to find this comment...

I like how "New Guy" is blocked when he makes the save, but is in the background of the video later anyway.
The most dangerous thing was the intake and I'm not even sure they have realized it. Blowing out this much air means the suction power is equally strong. And yes, this is literally an electric jet engine... I'm quite sure it was designed with airplanes in mind.
I'm sure there is a nice fat warning label when they opened the box. Also, they've kept their distance from it in case one of the blades should break.
they said 60kgs of thrust at peak - that's not a whole lot for an airplane. A cessna 150's prop is about 230 kgs
I'm almost certain they would of taken into consideration the suction of the thing they aren't stupid.
@@magica3526 For an airplane it would be a bigger version which drastically increases the amount of thrust.
Yeah I was thinkitof that as well - it could easily suck something in and make all go haywire - I work with MRI and and it's the same, everything is fine until it isn't ....
You gotta get those mythbusters bulletproof glass shields, this is crazy dangerous. If something got sucked into that thing (very possible) and shattered parts of the blades out the back at full speed someone could get really hurt...
Honestly, yeah, Linus going anywhere near the rear when it was at 100 A was having one foot firmly planted in the grave.
I was wondering when someone would feed it a carrot.

As a prior safety rep and aircraft maintainer, this scared me. Even just standing in front of the prop circle y’all were playing a dangerous game.
as a leyman in aeronautics, what do you mean by prop circle ? do you mean the width at which the prop projects its output ?
disregarding my knowledge of aircraft, i still know this video was a dangerous game.
@@dominickkramer6469 think of an area around the blades of the fan, propeller, or jet engine, as a giant circle. As they’re spinning at high speeds, if any single blade were to be unbalanced, they could break and shoot out in any direction of that circle. Aircraft have a line marked on the fuselage to show where not to be if this happens.
In the video, they were standing directly left or right of the fan in the area of that circle.
I was just waiting for a LTT water bottle or a pink wig to be sucked into the fan while drawing 100A.🫣
As it's it's ducted design, I would imagine (and hope) that the casing is designed to contain shrapnel in the case of a blade-off, in the same way as the nacelle of a jet engine is designed and tested to.
@@chrisburn7178 Nacelle is designed to hold it, yeah. But it isn't strong enough to come through it intact. The nacelle is designed to bleed off energy by blowing apart tossing lower velocity shrapnel everywhere. The underside of the wing and passenger compartment that are inside the prop circle are reinforced to take not just those hits, but the full hit of a blade coming off and hitting the plane. The idea is that once the shroud violently deconstructs itself from the first indecent a second blade could break off afterwards before the engine is shutdown. So the wing and body need to be strong enough to take that second hit. Those areas are actually the strongest on any plane. When dealing with those types of forces it's just stupid to trust anything to work without a backup.
Them playing with the fan reminds me of the time when i was mech infantry. We were getting ready for a training mission and got rained on while prepping our bradley fight vehicles, I was soaked. The tankers next to us fired up the jet engines in their abrams, and I had the brilliant idea of standing behind the rear of the vehicle to dry off. I lasted maybe 10 seconds, behind what felt like 1000 hair dryers on full blast before running back to my gunner seat. I was warm, dry (and inturn happy), and had a new respect for their engines.
My close friend was in the army and drove a Bradley and he has similar stories sanding behind the abrams when he was stationed in Europe during the winters lol, god bless gas turbines
