For you future projects i would recommend using WD40 for a lubricant, as water (in most cases) will slow you down due to it wanting to stick to itself and as well as the rotating parts. However, i understand if you don't like the idea of oily residue on your legos.
wd40 isn;t really the best lube tbh, its only marginally better than water and is very short term something like bike chain lube would probably work best here

Use a rpm reading thing. The gears used to measure the rpm put a lot of drag on the system. You can hear there is a big difference with the rpm with and without
There's another way you can estimate speed - sound. Record the audio with it spinning at a known speed. Put the audio in a audio program (like Audacity) and have it do a spectrogram. You should see a strong peak at the known speed. That corresponds to the speed (albeit in revolutions per second instead of minute) or a multiple of it. Then take the gears off and repeat. You should see that peak move, so now you can recalculate and get the speed.
Worm gears are famously inefficient. Like 50% efficient. If he needs to record speed but needs a reduced output, use spur gears, as they're typically 99-99.9% efficient. I've had extremely low power systems with 300:1 spur gear reductions run totally fine, but one worm gear, regardless of the ratio, will kill the same motor.
it may vibrate due to imbalance, like one moving part is slightly heavier or lighter than others might just be the air moving real fast might be friction between parts also powd graphite is a lubricant, literally just pencil lead but crushed up
Oh, I get it, it seems that you're getting light lag. You're at a point the RPM becomes its own gravity, causing the weaker side to break. That's just a theory.
For a future version, perhaps you can get metal technic axles so they don't wear out quite as much? Also, someone below mentioned using an "rpm reading thing" for better speed due to decreased load on the shaft... if you do this, I also recommend using a wheel with a marking on it instead of the spinning tooth thingy, to minimize vibration. I look forward to this series of competing engines :P
I think the style of his experiment is that he didn't use anything complicated, even manually timing the RPM only took a few more Legos instead of digital tools.
usually, we use oil rather than water because water has a much higher surface tension on top of being more reactive with our traditional metal engine components, generating rust which weakens the components on top of their existing wear and tear a "dry" counterpart is graphite
Nice!! Incorporate some ceramic ball bearing into that thing... it'll REALLY rip, then :) edit: and the gear reduction timing mechanism really slows it down too, I bet
@@-ul7lh Every time I open the latch and just remove it before putting it back. I'm thinking about the resistance to air flow it causes when used in an application like this :P
Made a similar vacuum turbine that had triple the blade length and double the width, with an air inlet the same length as the turbine. Spun not as fast but that thing made a crazy amount of torque!
For your future motors, I would recommend using wall pieces instead of bricks (or even having the wall pieces inside and the bricks outside for stability). This could result in less air escaping from the walls and lead to higher rotations.
I thought this guy was just a guy building Lego but NO not at all he’s a full on mathematician genius ! Keep up the good work and you will be soaring in subscribers 😊
Sounds like an air drill! Id be really interested in the torque output of that bad boy. I think electric motors are great but adding variety to some builds with different power sources seems fun
It's a three stroke rotor engine First stroke: vacuum goes from the vacuum cleaner into the rotor chamber and the rotor starts to rotate Second stroke: vacuum in the rotor turns into air Third stroke: the rotary engine spits out air from its chamber and so on in a cycle BUT if we install a spark plug, then the 3-stroke engine will become a 4-stroke (at first glance) and the spark plug simply will not ignite the vacuum mixture
Just a note for your futute iteration since we're doing all this science and you seem receptive to input - if your timer is only 3 significant digits (2.87 s) then your RPM count is the same! So 1.20 x 10^4. With a laser timer I'm sure you'll get it even more exact, though. This also means the older record is likely more like 11.5 x 10^4, so you've definitely got it thoroughly beat!

Silicone lubricant is far better for lego
I did it first with water and noticed how much it spread on my table, so I decided to stay with it... Maybe next time I'll try it...
What about graphite from a pencil? I’ve seen other people use it as a lubricant before

A bit of silicone spray lube (jig-a-loo or similar) will save a lot of wear on your moving parts and likely help get higher rpm than water.

A lot of comments debating the best lubricant to use on your Legos, but nobody has mentioned sewing machine oil. I think that would be a good choice.
Good point, but I think Graphite powder is even better...
At first I thought you were creating an actual vacuum with legos, like something that sucks up air through the power of legos somehow.
I will try to do that soon!
Made a similar vacuum turbine that had triple the blade length and double the width, with an air inlet the same length as the turbine. Spun not as fast but that thing made a crazy amount of torque!
