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.

@@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.)

[@britskaradiometeorograph8108]

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

'' We've thought about this, where's the hammer! '' probably the best quote on this episode.

[@yeahmanitsmurph]

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.

[@dominickkramer6469]

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.

[@yeahmanitsmurph]

@@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.

[@zor8952]

I was just waiting for a LTT water bottle or a pink wig to be sucked into the fan while drawing 100A.🫣

[@chrisburn7178]

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.

[@halycon404]

@@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.

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?

At a malt plant I worked at we had 15ft Dia. Fans that ran off a 500 HP motors. That blew air through a bed of grain. Those were impressive, oh and there were 4 of them. There were air lock doors because it was close to impossible to open the doors with the fans running, and it would blow you off your feet to walk in front of them.

[@TNIPPER]

What plant? Was it milwaukee

[@depravedrogue]

I was nervous the whole time. I'm not a fan expert or anything, but with that much power, it seems to function like a tiny jet engine. I would want to cover the intake with something to prevent serious injuries from something getting sucked or accidentally moved into.

[@jooplin]

This is the type of stuff were you feel confident because there is never consequences but when there are just one time, in this setting you could literally kill someone. I found the whole setup extremely irresponsible and dangerous. Stuff loosely lying around, no covered intake. People shouldn't be standing in front of it when there is a possibilty that a part of the PC comes loose and flies into someones face at 200km/h. This shit is not safe and there should have been a security advisor of some sort. In germany this place would have been closed down already.

[@foxhoops97]

I thought I was one of the only ones that strapped fans of that caliber to a PC to test how good and rapid air cooling and response can be. Mine was only 200mm but it was an RC Jet fan with 8KG of thrust Also I recommend copper heatsinks plus stopping the airflow from going anywhere except through the heatsink as air will want to travel the easiest route, if you seal everything you will also condense the air as it goes through allowing for far greater pressure on the heatfins allowing for far more contact and far better cooling. Also I recommend RC Jet fans as they are built for both airflow but also they naturally handle condensing of the air into the output while creating a solid static pressure due to their job being to provide thrust.

Hell yeah, there is no better LTT content than another chapter of Linus and Alex making some janky cooling project!
