This Lego Vacuum-Powered Generator SUCKS!

Patreon: www.patreon.co...
See my latest experiments and behind-the-scenes footage!
Let's suck our way to generating electricity using Lego! In this video, we experiment with a few different 'Lego Vacuum Engines', and use a powerful turbine engine to drive a Lego generator made of large neodymium magnets and 3 coils of copper wire. This generator outputs a 3 phase signal, giving us a nice smooth signal at quite a high voltage. The current is limited, but this gives me great hope for an upgraded version with beefier coils!
Now it's not lost on me that we're using a 620 watt hoover to generate only a small amount of power. But this sure has been a fun experiment using a vacuum to drive our turbine, and then using this to drive our generator.

[@Ewout761]

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!

[@JamiesBrickJams]

Yeah I'm almost tempted to see just how fast it could spin if I connected the magnets directly to the turbine without any gear reduction. But I'd be pretty worried about something flying off or creating a speed wobble. Perhaps in a future experiment!

Actually a vaccuum v12 will be far weaker than even a vaccuum 1 cylinder. The reason is because the vaccuum will need to spend more power to move 12 entire pistons instead of just 1. The axle will also have more rotational inerta in the v12.

[@Ima_banana2]

How about you power the vacuum cleaner itself ?

[@Tsskevik]

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.

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?

[@noctisumbra3015]

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.

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.

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! KZbin 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. KZbin should ask the Creator if the Thumbnail represents honestly what's in the video, if not KZbin should place a "Fake Thumbnail" watermark over that video's thumbnail. Power to the People.
