Does a fast gearbox generate more electricity?

Anyone who knows a bit about friction knows the answer up front. Still a nice Video

Maybe get a bigger Handle and a Flyweel amature xD

It will generate more electricity if the motor has been turned clockwise 🔁 quickly enough to be an electric generator that is hand powered and can charge up batteries 🔋 and light up lightbulbs 💡 or even a small heating element ♨️

Mauvaise comparaison .

why it doesn't explode ?

this stuff is pretty elementary, more gears doesn't mean more "Free electricity". Can you progress this project into an exercise bike version. I'd pay money for a under $300 version that can power small laptops or store electricity in a battery.

Yeah I learned that you are a lier that the large generator wouldn't work on the fast gear

I'd be interested to see you use a higher gear ratio for more spins, attach the bigger motor, extend the handle way out at about 75°, then add a heavy weight at the end. The handle will only turn roughly a quarter but the spins a power generated should be high.

I have small friction engine for toy car how can I speed up that friction engine

Barely spins the little crank, goes to town on the big crank, calls it a legit test.

Just find something that is in the middle ratio... spins fast enough for higher voltage on the big generator but still able to crank easy enough

Add a flywheel to your design so you can produce the torque you need to push the big generator

Instead of a hand crank could a heavy weight on line that unravels as it falls (slowly due to the resistanceof the gear ratio), maybe the height of the room for prolonged duration?

Any generator will provide more electricity if driven at a higher speed but there will be an optimal speed above which the output will begin to fall as mechanical and electrical losses increase. The losses will appear as heat.

This comment section full of electricians makes me feel like a kid that was adamant about sitting at the grownup table

U should spin a magnet. Spinning faster brings more electricity and no frictions.

Apply a significant load and there will be great difficulty keeping up higher RPMs.

Why you did not use the fast gear box for big generator?

Use ball bearings from rod to gear, for smoothening the spin

All metal gearbox please!

Nah this video is misleading. Big generators can give out high voltaged and high amperage if spun faster.

Could you do this with a drone motor for the small one instead please

Or even with an axial Flux motor. There's a bunch of different designs. You should also use I think they're called herringbone gears. They've got teeth shaped like a V

Comparing the two vastly different motors on two vastly different gearboxes isn't really an accurate test, especially when only one of those gearboxes is built with stability. You need to redesign the multistage gearbox so that it's mechanically stable and then use that one and only that one to test both motors at each stage. You also need to use two meters or a single meter with multiple readouts to measure both output variables at once.

Stay with your gearboxes , they are nice...but never touch a multi-meter again :))))

seems like, for this to be a fair comparison, you'd have to use the same alternator for both setups. different sized alternators will have different efficiencies.

Let me start by saying your video was well done, there's only one little problem with it and it can be solved with going through history. Keep in mind I realized that you were doing a basic demonstration but these demonstrations were also done when I was in high school , studying automotives and gear ratio If you know where I'm going with this then you should realize that these problems have been solved. But people in today's society seems to be talking about them much less then we were in the past. Small suggestions to anyone who reads this go back and read old Popular Mechanics not to say that they didn't have the technology we have today but they solve a lot of problems that are not even being mentioned in today's time. I told a friend this a couple of days ago and he called me back and he solved the problem with this suggestion , if you take 2 different devices that you think have nothing to do with each other but 1 solves 1 problem and the other solves another problem why not find out How to combine them into one. This is called unity.
Now if you haven't guessed it I am the person who created and develop over unity , my name is Lloyd G stovel And you'll hear me talk about these things quite often on my channel. I just recently started talking about how to overcome many of these things that seem to be misinterpret or just outright says impossible on my channel why because one Most of these things have already been done so I don't understand the big secret but it seems to be one anyway. I'm not going to lecture you here if anybody wants to know more this take a little look at the channel and overti'll explain as much as I can from a person who comes from your past. Let's see if that helps or ignored!

Why expensive? I am a machinist, could do it in a day with scrap...

there's a problem in your calculating .
When you measure the voltege across the motor , the internal impedence's motor is zero.
Because it's like an open circuit (the impedence of a multimeter has to be very high, in this way the current flow is almost zero).
So you can get an accurate voltage's value.

But when you connect the motor to the tester, for measure the current, in this case the impedance of a tester is almost zero, so the motor sees two impedances, that of tester and internal motor.
You have so a drop voltage that you're not considering.

So what is the answer yes or no

I'd just make a more powerful gearbox that can spin the larger generator at higher, more stable, speeds. If necessary, make it powered by a foot pedal with appropriate gears and a belt/chain, rather than a hand-crank. Much more bulky, but I'd wager more effective.

It also provides some leg exercise, so there's that bonus.

Though it might just be better to make a gearbox connected to a gear shaft with multiple gears along it at even intervals, so that you can use the separated gears along the shaft to connect several small generators to generate more power than a single larger one. Or maybe a gear shaft connected to multiple gearboxes.

If I try to make one, I think I'd try out a slightly more complicated form of planetary gear box if I can just work out the measurements and how everything should fit together in my head.

what if u put bigger electric motor on fast gearbox?

Bigger motor means it needs HIGHER RPM IDIOT!

you can put motor at the input so you can generate big volt on output (generator)?

why are you not using the same motor on both version ?

Would it be economically feasible to create a human-powered generator using a gear ratio like this?

to store energy Add an old school Flywheel !!!

I would like to see a full metal version of the gearbox

make a big size gear box that can generate torque enough to rotate the big generator

This is so funny how you are measuring amps

Why can’t you make a bigger gear ratio, then add a electric motor to spin the handle for you once you manually get the momentum going and just have the electric motor spin it later on producing more electricity then used,
Or am I speaking out of my ass, I feel like this would be something that is possible, unless what you mentioned about not enough torque would matter

what if you connect the small motor into the place where the handle of the big generator is and power the small motor with the current produced by the big generator
