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.

Thanks 😁 It's obviously totally impractical but a fun experiment nonetheless!

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.

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

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.

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?

awesome build

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.

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

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.

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.

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.

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.

For sure, I've actually been tinkering with a Tesla turbine for a while. It's unfortunately really difficult with existing Lego pieces, so I may have to resort to 3d printing for the flat blades

@@JamiesBrickJams I'd suggest using thin steel or aluminum discs with a .5mm thickness if you can, they are much more resistant to speed, but it can be a bit troubling to cut out the holes. Also, I wouldn't worry so much about cheating/not using lego pieces, the best designs will only be possible with at least a little bit of this type of cheating

How about adding an RPM govnor to keep the RPM and thus voltage stable even when the load changes

Oooh that's a really cool idea, cheers for the suggestion! 👀

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.

I'm right there with you, I've been looking for an elegant way of blowing air for a musical instrument for ages. Sadly this is quite challenging using Lego, and I've a suspicion that any method of compressing air or creating a vacuum using Lego is going to need to be so airtight that only pistons are viable. Though I'm working on a Lego bellows that might be able to sort of work (badly). The best vacuum I've managed to get working is the peristaltic pump in my drink cooler video, but it's super weak, and only useful for thick fluids like water

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.
