One day he'll spin a gear so fast it fractures space and time

It'll go faster than the speed of light.

Science 🧪
You should get a motor with a speed controller so you can speed it up slower because the acceleration is what sheered the gear off
If it’s not accelerating then the only resistance is the friction
The increase in temperature due to friction decreases the strength drastically
In future videos, and if you have one, can you record some videos with a thermal camera? Would be curious to see if friction is really heating up any parts or not.
And I hope that he will comment some comments here
Those can be pretty expensive
@@GBduds It would be so cool though, you can visually see where you need to make less friction to improve the efficiency of the gears. Can play with different gear tooth shapes to see which is the best, etc.
Pov: it’s 1 am, you told yourself you’d be in bed by 11 and your binge watching his entire channel.
It's 2:05 am and I should be asleep but I'm working on my channel😉
son of a bitch it is literally 12:59am , you're a wizard
One these days, you'll go too fast and we're going to get a video called "I blew up my house... WITH A GEARBOX!" :P

the table slowly becoming more and more broken should stay a thing
but then he will have to buy lots of tables
Fun fact: videos like these inspired me to start playing around with gear ratios in DT at school recently
Slow-mo disc grinder sparks set to low-fi chill beats = The video we didn't know we needed.
Really cool to see your progress
"gravity generator"
Scientists: *WRITE THAT DOWN, WRITE THAT DOWN!!!!!*
@@kevinbissinger yes but imagine if they combine this and the mechanical batteries
Fernando Queiroz Popovic I actually saw something similar to this being used to store solar power to be used at night because you can get super high capacities and it requires relatively low cost and upkeep compared to traditional batteries
He just invented the pendulum clock!

this right here is some damn good content
What song is playing during the angle grinding montage?
Nice content, love it.
I too, feel a really strong connection.
The idea of a gravity generator is definitely interesting, and imagine it could use that generated power to lift the weight up! Definitely one of the more efficient concepts for unique generators I've seen
In a 100% efficient system, where all the gravitational energy of the weight went into the generators power, the generator would have to use ALL its power just to lift the weight back up.
And real life is far from 100% efficient, meaning you'll never generate enough energy to even lift the weight back up. Which is why the only situations in which a weight based generator makes sense, is one in which we don't have to lift the weight up ourselves. For example, water flowing through a damn, is lifted up for us thanks to the energy from the sun. We can then harness it back through the gravitational energy of the water as it falls down and transfers some of its energy to the generator
_heat_
nice job buddy 👏
now think, for the single microsecond that the gearbox survives when you rotate the first gear. What rpm will we reach?
What would happen if you were to hook up the same gearbox in reverse so the ratio ended up being 1:1, would you be able to spin the last gear or would friction or some other force prevent that?
Dude! Congrats on getting the trending "creator on the rise" thing!
Would you remake a better gravitylight or something better?
You deserve more support.
What are the logistics of using the gravity fed generator? I have a basic understanding of alternators and and the gear reductions involved but would this be a viable way of producing electricity? Would a long enough pendulum and a large enough gear reduction with an alternator at the end produce electricity? Thanks for any answers.
Yes, it's a product. GravityLight produces enough electricity to power an LED.
Have you considered using bearings pressed into each side of the gears, the more gears you add to the set the more friction your getting between the gear and the shafts, bearings should help minimise the drag of each gear on the shift and give you better efficiency with your power input
You think he would have. I build custom gearboxes for my rc cars that do 10k rpms and bearing are a must lol
Of course bigger/more is always possible, but part of the fun in this case is doing it with as much printed parts as possible. Otherwise he could just as well build sets of metal gears. In this case the one that failed really needs a bearing. That first gear takes the strongest forces. It failed where it rubs on the axle. That could have also fins added to dissipate heat.
Id LOVE to see you break the sound barrier
I'd like to buy one of these! I think it will work on a project I'm building.
this is fascinating
There are gravity powered lights that use that same idea, very cool
You should do an experiment to see how much you can lift with air. Build scoops on the first gear and a pulley on the last.
Use magnetic tip gears si you can get rid if some of the friction?
You could have just stuck a gear in a stick and blew air over it to get the same result
Outro song? Love the 80’s vibe of it
1:27 30 bucks for a 4 1/2" grinder at harbor frieght and about a dollar for a grinding wheel
I think Ikea must love your channel because of how many lack tables you buy from them for these videos. They should be sponsoring you!
What if we use a gear ratio to increase speed then that fast spinning gear is connected to increase the power
One step closer to the speed of sound!
Pretty Cool, could you design a set of gears for my own idea?
Doesn’t seem like you care too much about that table, but if you ever end up making something a bit more permanent, make some holes at regular intervals and design your axle holders (?) to use bolts so you can just bolt and unbolt rather than having to rely on the screws into pressboard
Cant wait for the day we break the speed of sound it rotates so fast
How well are the gears holding up
You should probably use herringbone gears. Much more efficient and reliable.
Anyways, if you were to stick a driveshaft on the end of this, and hook it up to a network of differentials, CV joints, gearboxes, overrun clutches, centrifugal torque converters, flywheels (for smoothing), Geneva mechanisms (for timing), mechanical multiplexers, manual clutches for disconnecting things, and so on...
You could effectively build a power grid for transmitting rotational torque over very long distances, like entire cities, to any machine that needs it.
At sufficiently high gear ratios, almost nothing would be able to interfere with the torque while it's in transit. Not even a pipe being accidentally filled with concrete, as the concrete would just get ground away.
Me, searches Google :happy new year fireworks.
Happy new year fireworks : 1:29
I made one of these in a robotics class and it went 50k rpm with a really weak motor
I've literally been thinking about a gravity powered generator!!!
That music like transported me to another universe. A little overkill for a video like this.
Why cant we use gear ratios to maximize the collection of gravitational energy?
Very cool, but are you really grinding sparks into your white walls?!?
4:06 I hope you can make another video to show how practical making gravity based gen, basically put weight and string and let it slowly drop let say on 3 meters height, depending on motor generator/battery size would really great to know how much it can store energy in the lithium battery. try on small scale like 20w dc generator and 12v 10ah lithium battery setup.
What if you had some frictionless, unbreakable, harder than diamond material, and made gears out of it? What if you made the largest gear ratio possible with it, to where the one at the end moves faster than light speed? Would that work? Could you make a lightspeed catapult with it, or would the slightest resistance prevent the gear from spinning? If so, what if you make the craziest motor or engine possible, making your lightspeed catapult, or put it in space for no air resistance?
Gear Ratios seem like a cheat the developers forgot to take out
Hey, mechanical engineer here:
Based on the way the gear failed by shearing along the layers, you should try printing the gears upright, or at least at a 45 degree angle.
You gone to need a plexiglass shield and PPE if this keeps getting faster. Haha
Ok, that gravity powered gearbox gives me ideas.. I wanna make a gravity powered AC generator using a gearbox and a weight.. Man, if only I have the tools and equipment..
Ok so I might have to make some money creating a gravity generator 🤔
Some engineers developed a gravity powered light for 3rd world countries a few years back. It used stones, sand, dirt etc for a weight and had something like a 20 minute life before someone had to reset the weight
I want to create a metal gearbox with bearings to see how fast we can go
I wanna try this out with metal gears..
the torque could lift me off the ground
if you make a very strong gear box (like large metal gears), you can make a huge ratio. Obviously there would be difficulty with spinning the first gear as there would be so much friction. So, thats where the fact that the gearbox is strong would come into play. If you make a large crank, and a secondary gearbox (smaller in size and ration), you can use the secondary gear box with a power drill to pull the crank (like how you spun the last gear and made the heavy drill and battery go up with ease).
Here's a link to a video which shows just how strong the gearboxes can get, if you do it right.

Something that would be interesting is, if you had enough of these,so it went *really* fast, would you be able to generate energy from it, to recharge the drill? So like.. infinite energy? Probably not, but would still be a cool thing to try, like how much energy you could make from it
Theoretically this can be used to do nano-scale manufacturing like microchips.
Making a perpetual motion machine with gear ratios would be awesome.
Let me introduce you to electroboom...
Also thermodynamics says no
Would you be able to attach this to something that would be able to create energy..?
umm an energy generator?
can u make a gearbox with rpm:rpm ratio 0:infinity?
You should add some fidget spinner bearings to the gears
4:16 that. Lookss sickkk
I enjoy watching these, there so simple at they’re core but so much fun. Guess it just goes to show that the simple things in life are the best . Stay simple n love life holla!
I’m into gearboxes know cuz it just popped up in my head.
Hey! Here's an idea! Have you ever tried using planetary or epicyclic gearing? I've read that it's actually more efficient this way and takes up a lot less space!
This video uses epicyclic gearing for speed reduction, but all you have to do is reverse the consist (have larger planet gears serve as carrier input and much smaller sun gear as output, ring gear stationary) in order to significantly increase speed: th-cam.com/video/ARd-Om2VyiE/w-d-xo.html
From where I buy this
This video feels longer then 6 minutes.
Put some oil on the shaft it helps a lot
Suggestion: make a gearbox with 20 gears kinda like a truck gearbox
Are hydro damns basically gravity powered electric generation?
In a way, yes
You need to cool down the first pinion of the chain to reach a higher record.
Work up to a burst gear. At a certain speed the gears wont be able to sustain themselves and will catastrophically fail. Wear safety glasses. It may release a ton of energy.
bro u should probbably buy a drill that connects to your ac plug as it can withstand high torque
My bro spin the gear ⚙️ so fast let the Earth go back to the Stone Age 🪨
3:26 18000 RPM
Take a shot everytime he says “shaft”
I remember commenting about the possibility of a gravity generator on the previous gear box video, I'm glad that the gravity generator was brought in this one! It would be awesome to see a full video exploring the potential of it!
Kkkklkkkk

Sooner than later you're gonna need a plexiglass shield or something.
Why haven't gravity generators ever been a thing? There has to be some reason why it never came to be
How much torque produce
Or you could have square axel to fit onto the handle to make it strong and then add epoxy.
Idk your setup but it looks like you are doing this in front of you? You may want to stand to the side so you dont get shrapnel to the head at 30000rpm
Helo sir faster gear bana sakte ho kya jo
Long Windup spring with gear box and solar panels with a auto windup electric motor would be good free energy generator
That shaft is hardenable steel, you could tell by the sparks
Look at the spark lenth its normal low carbon steel
@@TheFighter667 look at the sparkly ends, it's atleast 4140
You’re doing great bus need to improve way more your axel set up
@Leon Aimene then he'll spin a gear so slow generating so much torque it will pull it back together.
Probably been said before but please don't stand with you in line with the gearsets. When they let go, you could be hit with shrapnel and lose an eye.
i need a printer and i need to do this.
Test it with an motorcycle engine on the last gear
spin to 19k on that end with air, and put a slow strong motor on the other end and push from both ends and then stop blowing and see if you can maintain 20k
Gotta try putting an electric motor on the slow gear, and an alternator on the fast gear. See if you produce more electricity than you use.
stalls the motor
Turn 500,000 rpm to algebraic expression
3:33 yeah lets replay something that we clearly saw
Why does no one ever try to use lubricant on the gears to reduce friction?
Why not lube the shaft with oil
