This Lego Vacuum-Powered Generator SUCKS! 

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

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

I like how because the vacuum is plugged into the wall, and that's powering the turbine, and that's powerful the generator, in a really roundabout way you've basically plugged the LEDs into the wall

You must say "Full Bridge Rectifier" more! We must spawn Electroboom edit: Thanks for 447 likes!

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

6:32 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!

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.

i like how it sounds like a 4 cylinder sportbike

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

March 2025: This Lego Jet Engine Blows!

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

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.

But can it run doom?

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

9:36 that one LED is like I’m special no, you’re not bud. You’re just ruined it for everyone.

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

I love that it sounds like a rotary, which makes sense given it’s moving air past 3 blades, just as a rotary does, even if it’s not a blade

11:00 the loudest lab bench power supply

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.

I’ve seen vacuum turbines my friends making hitting like 20k plus rpm. We usually use an oil like olive oil as lubricant when making engines and stuff, if not the axles start sheering cuz of the friction. You def need it for bigger engines like if you make realistic engines with cylinders and start messing with dohc valves systems and stuff. Cool video btw, keep up the work. 😁

Bro didn't make a generator he made a tornado siren

ah yes, powering a generator with electricity (with losses) this is revolutionary! why has no one thought of this yet?

0:45 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.

Average technic set:

This could honestly be an awesome over engineered show stand for technic cars

Imagine using this as a powerplant for a lego city

12:40 Now I dont have to worry about wasting infinite supply of air vaccum to charge my phone lol

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

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

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.

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

Btw hetty is so cute lollll😂

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

That Lego vacuum turbine sounds like a race car don't you think😊😊😊😊

As a siren enthusiast I can confirm this thing sounds like a thunderbolt blower or really high pitched model 2T

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

this would be a cool gadget to have in a house with central vacuum

Full bridge rectifier bro electroboom needs to be here

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.

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.

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

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

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

you should make an air raid siren along with an upgraded vacuum turbine

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

So because the light was flashing that indicated it was AC current and then using the capacitors changed it into DC? Is that what most generators have to do if they use magnets?

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

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

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

“You know I really don’t wanna get too buff” ahh video

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?

Mom:we have a generator at home The generator: a damn lego motor

If you want to charge a phone faster with high voltage, I'd recommend turning some of the voltage to current. I wouldn't push it though, as I don't know a phone's rated amperage.

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.

now try it with a smaller gear reduction to improve efficiency

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

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

6:54 flip the gears and he got a Formula One car

6:00 at this time you made some sort of blower seen on drag cars!

11:56 The light looks like a glowing piece of uranium to me

How about you power the vacuum cleaner itself ?

Fun fact: Vacuum Cleaner Motors are extremely cheap, something like 30 bucks for a 2kw monster It's just an idea... You can build your own vacuum cleaner, like I did...

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

13:26 bro was proving size doesn't matter

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

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

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.

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.

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

You can also use olive oil to make it run smoother

alright, we know 100% someone will make a house that uses these for its lights

Feels funny see someone do a mechanism which a whole community is based on (Do a dual rotar)

you could try making energy with pistons and compresed air (or steam)

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.

Challenge, make a compact Lego dam that provides electricity to a light

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

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.

why didn't u make the propeller go inside the vacuum hose?

Why didn't you fully open it to see the maximum power? 😭

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.

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.

7:26 man it sounded like a motorcycle speeding up

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"

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.

7:32 well its a 5:1 gear reduction and you got 10k before so its gonna be around 2k. 7:43 huh who woulda thought

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?

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

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

Add more magnets and coils to make more power!!!!

This guy will discover warp propulsion

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

To generate electricity with this, you first need a turbine, then a generator, then a motor, then an impeller, then another turbine, and then another generator.

The pun on the video title is just insane

If you already have 3 phazes why not build second generator and try synchronizing them? Maybe even build lego synchroscope?

You should put more copper around the magnets

3:51 you dony have ANY kind of tape laying around?

Does anyone know what his ground plate is called (at the start)
