LOVE IT! Please do a V2 of this. You lose a lot of energy from air, so putting covers on the sides of the wheel to reduce airflow should help reduce drag. Try balancing it so it can handle higher RPMs and put more weights further out on the wheel. Reducing friction is the most important thing to keep it going further, so consider lubrication for the gears. Will be waiting excitedly for the next version of this! Subscribed!
Hey thank you so much! Really appreciate the feedback too! I do plan on another version hopefully within a week but if not it will definitely get done! 😀
Hey there yes I’ve been reading up quite a bit since! The flywheel use in the lmp1 cars a few years ago was a genius way of getting serious hp for a few seconds after each braking area. 😀
I showed my kids the video, and it blew their minds. They spent ages trying to figure out how it was able to move without any motors; they then decided it must run on magic! A great concept which sparked my kids imagination, thanks Gaz 👍
Awe cheers Lee that’s great to hear! It won’t be long before they say , ‘Dad it’s clearly just the release of kinetic energy’ with that look on their faces!
Even though flywheels aren't very practical in lego form I appreciate that you made this. Using all those little motors in parrallel was a genius move as well 👍
Cool idea! I’d love to see another version higher gearing. What about adding more weight to the flywheel? Some lead fishing weights are cheap and effective.
Good idea I was hoping to do a comparison with lighter and heavier but the launch mechanism wasn’t consistent enough. There is quite a bit of weight in those circular pieces though😀
@@GazRsExtremeBrickMachines Maybe try increasing the radius and/or velocity instead. Either of those variables would make it store a lot more energy than just adding mass to it anyway.
I was wondering does it have to be round to work the best or would a big hexagon work. At a guess it’s not as efficient but if it’s big enough and balanced… excuse the thinking out loud lol.
I remember these used to be a super common, hotwheels scale toy cars with an internal dense metal disk on a high gear ratio. I remember getting some in kinder surprises, even, but I could be remembering wrong
fill the flywheel with as many blocks as you can to increase its mass. it will be more efficient and store more energy. would love to see the car clear an entire obstacle course!
@@flipsy3107 if lego blocks can withstand the centrifugal force, a fully filled wheel is better than a wheel only has mass on the outer rim. if they cant withstand it, the outer rim is the first to go as it experiences the most centrifugal force.
@@Ballacha but that increases the total mass of the car. I hear what you're saying. A flywheel with more mass stores more energy. But the heavier the car is, the more energy required to move it. Mass in a flywheel is more effective closer to the perimeter.
@@Ballacha The energy stored in a given piece of mass is proportional to its speed, not RPM. Especially since the energy is at the square of the speed. So the pieces towards the middle of the wheel contribute very little, since they don't move very far per revolution, ie have low speed. Flywheels used for energy storage applications tends to aim towards having no more weight in the center other than what is structurally needed as a stable axel for it to run on. Since all bearings have more friction when faced with a higher load, and the only load the bearings in a flywheel really has to contend with is the weight of the wheel itself. Ie, we want as much of the weight of the flywheel in the outer rim of the flywheel as possible.
Yo Benen! I’d like to see it geared differently but I took it apart too quick lol. Just watch your eyes or tv.. when spinning heavy things fast with Lego! the flywheel did explode once and I was lucky 😂
when i was probably like 8 years old, i had a toy car, with magnets under it, and you would push the car in a direction, and it kept going for a while and it was one of my favorite toys. now im 23, and just realizing this is the closest ive ever come to figuring out how it works. thank you for making this video!
That studio looks amazing! And so does this project! I honestly did not think it was going to get over those tires and then it just went straight over😂 amazing video as always! But I do wonder if maybe you put a lot more weight on the flywheel, I think it could spin a lot longer and maybe go up more obstacles🤷
Cheers Easton I bought a few things but the struggle is having a room big enough to film in, arghhh! More weight would definitely help! Those circular pieces had quite a bit of weight in them though and It expanded quite a bit when it was spinning, unnerving! lol
I think adding weight to the flywheel will help, it will be harder to get it up to speed, but it will increase the inertia making it harder to slow down
Beautiful engineering taking place here. I suggest lubrication (or at least something to keep heat losses under control, like water). I don't know if WD40 attacks the plastic used in LEGO, but that's another option. Some tin vegetable oil also works.
Interesting demonstration of momentum. You raise a good question on whether or not a GIANT flywheel is the key to giving long-haul trucks the torque they really need at stop lights.
Not yet but I will get some soon! I’ve just bought some great 1.5v lithium rechargeable batteries which have helped keep the weight down and have great power compared to my 1.2v 😀
Hey Chris I built this motor set up to spin the wheels fast off the axle! It’s bonkers lol. I was shocked what a tyre does at 7000 rpm! I’m hoping to do the video soon. I then started spinning this flywheel and this idea came along and a few others 😀
Very neat idea. Looks like the drive wheels could use some bracing to keep from toeing in. Also might get a bit better results if you could make the flywheel spokes a more solid disc instead; besides adding extra mass, it would reduce wind losses as the current spokes are acting a bit like a fan/impeller.
Hey thank you! Yeah the car itself wasn’t upto strength drivetrain wise and it let it down up the hill under load. You could feel it creating quite a lot of air disturbance too! I just wasn’t sure how to get around that with using these disks 😀
@@GazRsExtremeBrickMachines Thanks for the response! And neat to see that you tried this idea too in a subsequent video (though it looks like I wasn't the only one to mention it). You did a good job filling in all that space.
Hey Carl and thank you!! Happy New Year too! Funny you mention bearings as my next big fun build could really do with some! You’ll see my problem soon 😀🍺🍺
Argh that would have been great lol and thank you Mason! I would have needed to make the drivetrain a bit stronger but the torque was immense for 10 secs! 😀
Haha it was quite intimidating and I did keep well away most of the time apart from checking the RPM. When spinning the wheel in its own I nearly broke the TV lol
Could you try and build a steam roller? I don’t know how you would do it but it would be interesting to see how it would do in a tug of war. Maybe you could add elastic bands around the rollers for more grip or something.
A simple concept to keep in mind and experiment with: if your flywheel weights on the rim it'll be slower than if it weighs closer to the axle. Try experimenting making it different weights in different diameters
Hey thank you for that! Originally this was my gyroscope and if I’m honest I got a bit mixed up forgetting the flywheel mass could be all over. I’ve made another now😀
If you combine it with a fast motorised car it will have slow acceleration because the car's motors will have to "charge" up the fly wheel but once it is going it would be unstoppable because of the flywheel's momentum.
Hey Donnacha interesting idea! When I read up on flywheels I was surprised to see how often they’re still used in energy recuperation or energy storage!
You're reminding me of KERS, Kinetic Energy Retention System. Race cars equipped with it put energy into a flywheel when braking into a corner that can be reengaged to add torque on corner exit.
Energy cannot be created or lost. What ever way you chose to use the energy your putting into this it’s always going to be the same. What Is important is efficiency… and your “truck” is about an efficient as a piece of toast.
One places where energy is most likely lost is rather subtle, other than friction in the gears. The flywheel has an open section in the middle along its circumference, this will centrifugally push out air like a radial fan. Pushing out air in that fashion is a loss of energy. Just adding a single strip of tape would stop this.
Yoooooo that's a really cool idea! I like. Sorry for not commenting on your last few videos mate, hope you had nice Christmas and a great and gentle slip into 2022! Cheers bud✨🍻
I like the gearing but i think if you want a fast car do the same car but reverse the turning gears so that the inner wheel spins slower but produces more speed since the wheels spin faster
Air resistance is the biggest problem here presumably. As long as there is air resistance, you will get an exponential decay which means the usable energy that you get is logarithmically proportional to your initial rpm. So it if there’s a way to with minimal additional weight remove the effect of air (cover the flywheel in foil somehow) I would imagine you could get way better lifetime out of the craft
So One of my favorite toy lines is called Zoids (think Gundam but animals), and there was a subseries called Gravity Zoids There were only a small handful, three iirc, but it always fascinated me that they ran on a ripcord and flywheel rather than a windup motor like the other little Zoids or a battery motor like the bigger ones
I had a flywheel idea where instead of a bearing it was gears THEN a bearing. It was for a fidget spinner (golly) so it would push off the grips to decrease spend loss
Now instead of using the kinetic energy to drive the wheels, add motors and a hub and see if you can use the kinetic energy to gyrodance (= use gyroscopic precession to tilt the machine when turning).
That’s a great idea! Funnily enough I was watching the gyrocar video on RUclips yesterday! I don’t think I can spin a heavier one fast enough whilst keeping the weight down though! I will try 😀
Love how energy stored in flywheel is released slowly via torque that’s excellent for consistent crawling
Hey thank you very much! Glad you liked that! The torque for 10 secs was unreal😀

Kinetic energy storage is fascinating. From flywheels to gravity (lift with weights). It's amazing how complex and "smart" mechanical systems can be.

The mass on the outside of the wheel is more effective. Adding mass internally has less benefit as the car becomes heavier to push

actually most of toy cars i played with work with the same principle i even still have some of the fly wheels
The only problem is, it can only go straight :)
Air resistance is the biggest problem here presumably. As long as there is air resistance, you will get an exponential decay which means the usable energy that you get is logarithmically proportional to your initial rpm. So it if there’s a way to with minimal additional weight remove the effect of air (cover the flywheel in foil somehow) I would imagine you could get way better lifetime out of the craft
Definitely can win some races...
next: add CVT to drive forward, reverse, and stop(not neutral)
No
I think my head would explode! I’ve seen some have made them but I don’t think they could handle the torque :)

One of my favorite toy lines is called Zoids (think Gundam but animals), and there was a subseries called Gravity Zoids
There were only a small handful, three iirc, but it always fascinated me that they ran on a ripcord and flywheel rather than a windup motor like the other little Zoids or a battery motor like the bigger ones
