This Lego Vacuum Turbine Generator Sucks! 

"Yo bro can you charge my phone?" "Sure let me just get my vacuum."

You must say "Full Bridge Rectifier" more! We must spawn Electroboom

I'm happy to see that I'm not alone in using my tongue to measure voltage.

<a href="#" class="seekto" data-time="392">6:32</a> while 10000 RPM is of course a ridiculously high speed, the faster the spinning is, the higher the flux will be. And as the flux is directly proportional to the induction voltage, the higher your RPM is the more voltage you will generate. Anyways, love to see these physics applied in lego builds, it's really cool!

Awesome! I appreciate that you’re getting into lego air-flow based things now! Both vacuum engines and pneumatic engines.

Most people who are into Lego vacuum engines lubricate their axles and turbine blades with olive oil to achieve even higher RPM. Veggie oil works too :)

surprised this guy does not have more than 100k. You definitely deserve more than 100k for your work.

March 2025: This Lego Jet Engine Blows!

i like how it sounds like a 4 cylinder sportbike

Want alot of power? Make a lego vacuum v12 engine!

Btw hetty is so cute lollll😂

you should design a clutch for the hand crank thing attached to the red door, it should act like an E-Stop where the door closes and the engine stops

<a href="#" class="seekto" data-time="660">11:00</a> the loudest lab bench power supply

when i relized you ran those 3 12 volts on just one coil you kinda blew my mind. pretty awesome. now make one for a small steam of water

Slightly new here but just want to say that I love your work. Nothing more nothing less. I truly enjoy your content Keep your little light shining.

This is such a cool and interesting hobby. I'd love to get my hands on a collection of technic.

Thx for the videos! You inspired me to make a tiny Lego speaker because you made it look so easy.

Cool! I’d love to see more vacuum based projects in the future

You never fail to impress me… keep up the great work!

<a href="#" class="seekto" data-time="45">0:45</a> the LED actually flashes TWICE per passing of the magnet, once when the coil approaches, an extremely short interrupt at the center as everything is balanced out, then once more when it moves away.

You plug the vacuum into the wall, then plug the vacuum into a generator, then plug the generator into a light. It's complicating things a bit, isn't it? Lol, amazing work. Your channel is really cool! Keep it up.

mAN just casually electrocutes himself testing a lego turbine. mad. love the video

Can you please make sure that the final generator can power the vacuum cleaner? That would be nice.

This guy is gonna set the record for the fastest lego jet plane one day I like how you combine lego and electric components to make such creations, keep up with the good work!

hey jamie, i’ve almost been building these engines for a year on tiktok, but i’d recommend trying to port the housing a little more to optimize airflow, and definitely lube it (veg oil works fine, but i prefer wd-40 if you don’t care abt maybe damaging bricks more). I think it would also be cool to add a supercharger on top for fun (contact me if you’d like any help on that). Have a good one

Now connect it to something like a pi pico or a ti-84 and play doom, to say that you ran doom on a vacuum cleaner with lego

This is a brilliant way to show in a a practical experiment how electricity can be produced just by using airflow to rotate the magnet core.

If you want a vacuum turbine to perform well, you have to let the inlet be light and barely any friction in the inlet because it will let the engine run at its best rpm while having the inlet at a certain point where the engine likes it

So you're using electricity... to power a vacuum... to generate electricity. Love it!

A thought, If you enclose the generator portion between the vacuum and the vacuum driven turbine, it could perhaps reduce the air pressure such that the generator could be easier to drive. Maybe even house the generator within the body of the vacuum.

Nice to see the vacuum to phone adapter is going well 😂

WoW that was something super interesting!

awesome build

i love this series of making generators, please make a hydroelectric generator

Very cool! I've wanted to build a vacuum turbine for a while, although at the moment I have got myself a vacuum mill engine (which is basically just a steam engine with a very simple valve gear - used in old mills & factories, hence the name!). It runs quite well with a large flywheel to keep it turning over. Not sure if it's able to achieve the same results you have with the turbine lol.

While i do love this ingenuity , i just had to comment on one thing. I dont know i f you have an oscilloscope, but i would recommend that you get one to se the wave signal of your coil. because those coils are extremely inefficient. And since you talked about efficiency regarding the vacuum turbine, i would like to think that machine efficiency would also be equally important. While the magnet traverses over the coil, enveloping the coil, there is no induction at all. One would like to think that peak voltage would be at that point, but due to the coil geometry that is not the case. I would assume that the peak voltage positive is when the permanent magnet is introducing the magnetic field in where the edge of the magnet is aligned with the center of your circular core. and a new peak when the magnet is about to leave the coil. The coil in it self introduces harsh harmonic distortion which in turn creates huge losses. If you are going to iterate on this design, i would invite you to check out how coils are assembled in the stators, aligned perpendicular with the magnet, linear, non-circular. A bit difficult to explain, but check out for example lesics. Anywas, a really good proof of concept. i imagine, keeping your coil urn, id guess you would acheive atleast 60% efficiency if you redesign it. And that might be a understatement.

im so hyped for the video i love your content

i think you should make an actual turbine with steam sometime! that would be pretty cool imo

Epic video, as always. ;)

Wow ! Now, you just need to create a screen, and you have build a complete computer !

5.5F is absurd! awesome vid

Lol thanks for making a video about it. Maybe i can fit it on some of my lego technic builds that the original designs didn't seem to do very well with.

Very awesome and inspirational design! You think a second prototype can be made more efficient and compact?

This is so cool! i love it

Don't have the budget to patronize anyone (can barely make ends meet) but I remain a faithful humble subscriber. Keep doing cool stuff. One thing I would like to see is a Lego variable capacitor, it ought to work if you put aluminium foil on one side of the plate?

You should put more copper around the magnets

The pun on the video title is just insane

That's basically a backwards vacuum cleaner that turns the output vacuum of a regular vacuum cleaner back into electricity the same way it was created lol.

Fun and interesting, as it's really surprising just how much power can be drawn from just atmosphere pressure, if using a vacuum to direct it. But; I find the fact the word 'efficiency' is abandoned, yet still used early on incredibly amusing; because using a mains powered vacuum cleaner as the source of for this generator renders all efficiency pretty much void the second it's turned on.

Dude! you are so underrated

i love your content soooooo much!!!!

Nice job

Most vacuum cleaners also have an output, where air from the vacuum is brought out of the vacuum cleaner. Why not connect a hose to the output of the vacuum cleaner, and use on the input vent of the generator? Would it make more power now that are is not just being drawn in, but forced in? Have vacuum on one side of the fan, and air on the other side still, Add a flap to the air side so you can still control the power. Might even use a bigger fan to spin it, so you have much more torque and power.

Bro dropped another banger🔥🔥🔥🔥

Jamie's Brick Jams has got a brand new notified subscriber right now in me. My first viewing on this channel has been great fun! RU-vid can learn a lesson from this Channel on the "generating" of an honest Thumbnail that practically guarantees a "Like" simply for its truth in advertising alone. Being lied to makes for a shaky first impression and little chance for a subscription. RU-vid should ask the Creator if the Thumbnail represents honestly what's in the video, if not RU-vid should place a "Fake Thumbnail" watermark over that video's thumbnail. Power to the People.

I`m subscribing, this is very cool

You should be able to get an estimate of how much power your phone is taking by using an app to measure power going into the battery, and having it take measurements with the screen off so you can be sure that almost all of what your phone takes is in fact going into the battery. The only issue is that I'm not aware of an app that records historical power measurements. The closest I'm aware of is Battery Guru, which reports instantaneous power (which you can only actually see with the screen on), but only records historical current (which doesn't tell you much beyond a qualitative fast/slow without also knowing the battery voltage). I'm sure an app that does the right thing is possible though.

me reading the title: well i sure hope it does!

Try this with a lego vacuum piston engine, I've built ones before and the 1 cylinder has high rpms and decent torque with a good flywheel.

If you put a metal rod inside of the coils, they will actually produce more electricity than before.

Tip: and it may sound ridiculous with plastic but use a lubricant for a smoother use and less wear on the lego

Improvement idea: try building the turbo out of those yellow circle pieces it will be much more efficient

Are there low power vacuum cleaners you can use? If so can you turn this into an perpetual motion machine that actually produces power to supply itself?

Something you can do to get your vacuum cleaner my tightly fit onto the wall of the entry is putting one of those rubber LEGO tires onto it for a rubber seal, I've seen people do it on the world records for highest RPM LEGO vacuum turbine. Edit: Nevermind, you already did that lol.

<a href="#" class="seekto" data-time="806">13:26</a> bro was proving size doesn't matter

great channel! I subbed

Hi Jamie, could i ask if u send the link if where u have bought the copper wire used in the video please? Thanks!❤

Use gears to make the Generator rotor spin faster and Use Oil and mechanical Lubrication to prevent friction

While this more or less is a demonstration, you could probably use this generator with a vacuum generated by falling water! I don’t know any of the logistics, but seeing as it was a relatively low power setting and vacuum, running this off a small waterfall seems like a viable idea.

Try doing flat discs together, like a tesla turbine. Would be a cool experiment to compete with the normal turbine

"thinking quickly, macguyver produces a 15 volt generator using nothing but legos, a vacuum, and a 120 volt power supply"

this is so cool

Could you try building a windmil that generats power when it spins in the air

Its glorious.

Excellent solution. I think Lego Technic with electric parts would like to support for learning at teaching for physic or experiencing for electric technology. Thank you for saving my experience. I want to enroll for electric technology. 😊👍 i think i need to enroll for understanding how does it work with energy power like vacuum or wind power and how does it work if you add a chargable battery like at car without loading energy. If wind comes then wind boosts then generates more energies to battery? ⚡️

you can push 9 volts into your phone. most newer phones charge at 9 volts with usb pd. they keep the voltage at 9 volts but the phone will manage how many amps it takes based on the temperature and if the screen is on etc

Would like to see an ammeter added. Watts is a measure of power. Watts is amps x volts. The power output is the true measure of a generator.

Dude You Made A Vaccuum Engine LOL

Awesome video, but I got excited by the title as I thought this might finally be my white whale! I've been looking for motorised builds that can generate their *own* vacuum suction; ideally to fill up Lego pneumatic air tanks without the need for pump pistons. No hoovers or compressed air; just Lego parts. Do you think this sort of build would even be possible? The closest thing I've found is a mini centrifugal fan on Yoshihito Isogawa's channel.

Reciprocating piston vacuum engine when? They're very powerful and you'll get a lot more torque out of one than those propellers.

perfect title

Hey kid wake up Jamie made a new video your videos are great

It's amazing how something can turn 1kW of electricity into 30W of electricity and 970W of FUN

<a href="#" class="seekto" data-time="503">8:23</a> looks like da haydron colider

Can you try the small turbine thing you made at <a href="#" class="seekto" data-time="240">4:00</a> but scale it up to have more length aka more propellers and use it with presurised air

You must to do this with piston vacuum engine with one or two cylinder btw I from Poland (:

_Ohhhhhhhh!_ Now I get it!

at <a href="#" class="seekto" data-time="445">7:25</a> it sounds like an air raid siren

You're killing me with the square rotor in the round hole. 😫

I have also made a vacuum turbine but instead it resembles a supercharger with two two-blade turbines that are geared together and also not using the half studs you used to get a better seal

Didn't you used to be called Jamie's Lego Jams? Also - great video.

I was hoping if you still remember me the guy who was thinking about building a heating element so I can put it into my backpack for a lab and all that

This guy will discover warp propulsion

I want to see you attach this generator to a lego wind turbine and make some power without using power to generate your air

Yes it does

I would love that you beat the world record for the fastest lego vacuum engine (lve) ❤❤😂😂 good try!

Well yes, i would hope it does

Nooooo you cant just make power with Lego! HAHA turbine go BRRRRRRRRRRRRRRT

We love you bro

someday he will make a particle accelerator with lego.
