I work at a fusion energy research site and they use two massive 650 Ton 10m diameter underground flywheel generators to drive the field coils in the reactor. 400 MW/2600 MJ of energy is taken out in 20secs for a 9minute acceleration. Amazing pieces of kit!!!
So the new to build 18-20 of these for continuous power @ 400 MW. Wow that's awesome.
that is an amazing piece of kit mate - just plain awesome
I'd like to see magnetic friction free bearings with your flywheel.
In vacuum
I second that suggestion! ... Also, just to mix up the fun, I'd like to see the flywheel turned 90 deg., being supported by opposing magnets. The top of the shaft could be kept vertical by attaching a magnet to the top of the shaft, with another suspended above it to attract it without actually connecting with it. A bearing could be used somewhere along the shaft just to keep it stable while force is being applied to the wheel. ... That would be super cool... I'm heading to the hardware store tomorrow!! (gotta give it a shot myself)
Cheers!

I saw a video on CZcams that showed a guy that did magnet videos. He took CD case and CDs to make what you are saying ( horizontal/ floating on magnets). He add more magnets in a sandwich between the CDs. The magnets double as a flywheel weight. Then used the CD case as the housing And blew on it, through a tube.
It was obvious to put a coil out side. But he didn't show that.
Instead of hardware store, goodwill has junk CDs and CD cases and junk old vinyl records.
Why not do a big one with vinyl records? All you need are the magnets and Robert show how to easily build a simple case from builders board and sheet metal. And the magnets act as a flywheel as well as the generation.
I like that mate - well thought out
hmmm - interesting
Rob - You might just be trying to "keep it simple", but it is worth pointing out that flywheels are good for taking slow/small amounts of power in over time & providing high momentary power out. This is used frequently with hit-miss engines. It is a "feature" of many home-made wood spliters/choppers too.
thank you for making the point mate - you are right of course on both counts - I am trying to keep it to the core details
A couple things about flywheel energy storage:
They are constantly loosing energy, they have the most instantaneous energy when first charged.
To add energy to an already spinning flywheel you need to exceed the flywheels rpm.
Flywheels only store energy for a short time, you can't spin it up in January and used the energy in May.
Gravity storage will do all those things, and hold the charge forever,until used,
ah - I see you have a favourite method of storing energy lol
High speed fly wheel devices have useful role in energy storage but at the same time can be extremely lethal when they fail. 35 years ago I witnessed the rotor on a ultra HS centrifuge fail at 25k RPM due to a hairline casting flaw; very very nasty!
yes indeed
That is a great little lesson and made me have a greater understanding of flywheels
awesome mate -I am glad it helped
If I've remembered this correctly, you can shave and carve a flywheel to determine where the energy is stored within? It turns out that the optimum profile shape is very close to a figure of 8. All the best, Beamer.
Do you have a link to this that shows that? That sounds like a game changer.
you can and the shape you would make would depend on application - a crankshaft is part flywheel too - but you wouldn't want to do that for an energy store as it would just fly apart
Since you've got a flywheel you might as well build a homopolar generator. You know, because they're awesome!!!
nice idea mate - cheers
See flywheels being used on lots of old machines like wood cleavers and such. Thats because of a fact you forgot to mention and that is, it can add lots of extra torque for a short time by running off a engine on a constant rpm for instance therefore it can be a great help for short but high impact tools.
Had you mentioned Luke’s ‘secret plot for world domination’, I wouldn’t have been too concerned. However, you speak of a ‘plot for secret world domination’, which I think should be a cause for concern. I mean, how would we even know that you had succeeded?
I would use ceramic magnets instead of iron and resin. But brilliant video and planning.
Keep it up.
I like the magnets idea mate - cheers
the most well known flywheel is probably the fidget spinner.
for sure
Awesome! 😎
cheers mate
You forgot to mention that you have to equilibrate it for better performance. The generated vibrations that are due to the imbalance are far more damaging than your weak bearings.
no didn't mate - I just tried to keep it to what I thought were the core details
If a boat had a flywheel generator and used wave energy to power the flywheel to charge batteries to run a electric motor, that boat would be almost limitless in its range! 😁
yes it would
Brake rotors make great flywheels
For small projects. Truck tires are better for large projects.
nice one mate - if I had had one curses!
@@ThinkingandTinkering You mean the scrap yard does not have a few?
@@ThinkingandTinkering talk to your mechanic friends next door
One thing to consider, the behavior of a disc vs a ring rolling down hill
for sure
We need vacuum steam turbine running a flywheel now!
that would be cool
Rob, I'm watching this again. I have been considering the energy that is held in the fly wheel and how it is dispersed. The energy is stored in the inertia and expelled in the form of centrifugal release and through the drive axil. Is there a method to harness that centrifugal pushing force. This has also got my mind going toward understanding a little more about gravity.
hmm.. Flywheels suffer from friction: with air and with bearings. Since we're talking about mechanical batteries, I'm wondering if we could use a spring for that purpose? I reckon it has less (unwanted) friction and doesn't really degrade over time, when compressed (does it?).
I'm thinking about smth like a tube with a thread on an inner wall, a spring is inside the tube. At the bottom of the tube, there's a flat pin across the diameter (so the spring does not slide out). As external energy is applied, a bolt (?) is screwed into that tube, effectively compressing the spring. When the spring is fully compressed, the battery is 100% charged.
When we insert this battery into a device, we remove the pin. The spring pops out and is pressing on the device's surface, capable to accept this accumulated energy and convert it into whatever.
I can only think of 3 inefficiencies:
1. bolt-spring friction while charging (although chemical batteries tend to waste energy while charging too)
2. cannot be removed with partial charge remaining (the pin won't slide in as the spring is already partially out)
3. some charge is lost when the battery is inserted into a device (the gap between the pin and the bottom of the tube), although that's a very minor momentary loss
Would such a battery work? What do you think? What are the energy losses I'm not taking into account?
I'm inspired... heading to the hardware store tomorrow... I need some bigger magnets. 😀
Cheers!!
Go for it!
Wonder if you place a magnet on one side and a coil on the other, would the iron fillings change the permibility causing a chang in magnetic flux through the coil.
Maybe that why he did this, maybe that's the next video.
Thanks you for pointing this out.
like an axial flux path generator?
@@ThinkingandTinkering like a switched reluctance axial flux generator 😁.
A flywheel is necessary for 1 cylinder engines, I can see that. But in the days that I was working on cars we would make the flywheel lighter in weight to make the engine more snappy or rev. happy so to speak. It would however not not idle as smooth anymore. Thanks for the video!
the crank also forms a part of the flywheel
I understand the flywheel. what i want to know. how does the bearing push it? and freely spin.
I like it. i also thought if u compress a spring u could use the energy to power an electric motor or keep the battery charged up the bigger the spring the more energy like a wind up toy no stopping for fuel just wind on the go
U could even power the flywheel
for sure mat but it would be one mighty big spring
Are there any simple low-friction bearings for making heavy vertical flywheels?
Magnets for magnetic lift. Or a care ground wheel assembly (maybe).
yes - magnets - you can use pseudo levitation - I did a video on it
is there a general second hand stuff website which every day people from the whole country uses?
In the animation, does the flywheel effect efficiency? I wonder if the motor/generator could replace the flywheel by assisting the engine during the strokes needing assistance.
any transmission of energy from one form to another will incur a loss - so the answer is yes but it's tiny and probably less than the motor generator would incur
How well do they work in a vacuum?
I got a really funny idea... like if you ran a plane just dangling 33 foot tubes using tiny steam turbines to make the prop run!
that would be a funny looking plane lol
Hi Robert
It's so cool that you're bringing flywheels aigain.
Since the Competition you made there is a thought that keeps returning to my mind quite often.
It's about a kickboxing flyhwheel generator made of a stag of old car wheels with punching-pads (I ' ve found some wheels with a rim that were disposed in the woods) using the method of alternating magnets that you ve used with the 1kw wind generator series .
My question is is there a DIYway to connect a spinnable wheel on an axel with coils to a circuit. So that the relative speed of the magnets and the coils can summ up when the wheels get punched in different directions?
I mean a stag of flywheels that could be operated that way could be awsome .
Or is this compleet nonsens?
As I'am quit lefthanded with bouth hands I am trying to persuade some friends to make a team-project out of it.
Not sure if you want my input but if you go to the junkyard and get a rear drive axel with the rims attached. It would work by transfer the wheel movement to the center where you can attach your generator.
@@reypolice5231 Hi. Thanks all imput is welcome. I thouht of a car's axel (and bearings) in a strong wooden frame.
(Arranged vertically)
I guess you could try slip rings in the same way as an alternator works to 'collect' the current from the rotating coils
Question: is it way better than those old pocket watch spring to store mechanical energy? Thanks in advance
Unbalanced tires can be continuously balanced by adding beads, or bb's inside the wheel. I bet a hollow diy flywheel could be filled with something in order to balance it without professional assistance. Maybe water fed thru the axle that increases volume/mass after it has started
No, definitely not. Water by its very "seek own level" will not spin when the flywheel spins. You can prove this by trying to spin an egg - a hard-boiled egg will spin a lot longer than a raw egg. I suggest a truck tire setup, the heavy tire carcass can hold cement, drill 6 to 8 3-inch holes into the carcass to allow pouring cement. The tire rubber will hold the cement and not allow centrifugal destruction. Four truck tires can hold a lot of energy.
that sounds a bt of a scary plan mate - if you try it - do so carefully lol
@Michael Casper I'm talking about centrifugal forces balancing a cylinder. What did you mean by no, definitely not? Are you suggesting that if the cylinder was spinning over 10,000rpm that the water would be pooled within it same as air with only the boundary layer moving water?
or you can just throw it away by breaking like when a red light system is seemingly set to catch you at every red light LOLOLOL
World domination? Luke must have Klaus Schwab shaking in his shoes.
It's true. We've taken over the World THROUGH SCIENCE!
lol
I thought in the intitial part of the video you might have used the weight disk by your right side as this could be an ideal weighted wheel.
there are always options mate - tons of them in fact
They store energy in the form of kinetic energy. I think it's the French telecom system that utilizes huge revolving mass as a motor/generator underground in a vacuum with magnetic bearings for keeping the telecom system running during power outage. Very efficient solution. F1 flywheel technology has been researched for storing power under wind turbine generators. These spin at ridiculously high rpm and use carbon fibre rotors.
But the best ones are from India, where apparently, they sometimes produce more power than is put in. Apparently...... 🤣
I would be surprised if that were true
@@ThinkingandTinkering only the last bit was untrue. Williams F1 have done quite a bit of research on flywheel technology.
Good task for SUPER CAPS..
for sure
'always' is a strong word...
yes it is lol
To keep a car from sliding on ice in the winter can one use a flywheel to keep the car going straight? using this only during winter times...DVD:)
just turn into the slide mate
@@ThinkingandTinkering What is the fun in that? am sure a gyro would be more interesting... DVD:)
How about some circle neodymium magnets the thickness of the flywheel. Great video as always!
Cool idea!
How large a flywheel would be needed to run a typical house for 6 hours a day?
They got videos on this. Commercial units at 10 KW. So depending on your set up a small one charging batteries up overnight ( cheaper build I think) or really large to a small generation for a day or two. Still need it sent to a battery bank I think.
there are quite few design considerations to answer that mate - like how fast will you spin it - what do you need in terms of power to run a house etc
@@ThinkingandTinkering the average consumption is roughly 25 KWH, with a bias one could expect 6 hours to require 10-15 KWH. To make it easy math, say 2kwh per hour. Assuming the house owner has 3 sq meters in their basement and 2 meters high to make a concrete flywheel system out of concrete, would this give you sufficient parameters to make a small home non-chemical battery system?
@@ThinkingandTinkering oh and thank you so much for responding. I am very much enjoying learning from you about so many things.
Unless you use magnetic cogging as in the Hattem patent. Then it becomes ou
does it now
🙏👍🙏
cheers mate
Car brakes need to be designed with flywheels so they require less energy to start moving again. I know there are similar devices in some cars but all cars need these to reduce fuel consumption.
That is the march to electrics - every electric vehicle has regenerative braking, to conserve power.
for sure mate - isn't this KERS you are talking about?
At 1:30 seconds:
Secret plan for world domination???
HA HAHA HA HAHA 😂😂😂😂😂!!!!!!
Check out, Pinky and the Brain Cartoons. He has master Plans all laid out to perfection.
lol - will do mate lol
@@ThinkingandTinkering
But Dexter's laboratory cartoons will be especially helpful, he actually gets thing done in spite of Dede his sister making a mess of things.
Despicable 1 and 2 also hysterical stuff a foreign scientist in England. Hope you got some free time to watch these cartoon with Luke. Biting satire on real life.
Robert: "But the energy always remains less than or equal to the energy I put in."
Another idjit on CZcams asking why electric cars don't have generators on their wheels: "I'm gonna pretend I didn't hear that."
I wish I was joking... Someone once spent days arguing that the regenerative braking will magically fill the battery while the car is driving and, very importantly, not doing any braking.
A magnetic bearing is only as strong as the magnet and that is not very strong. Physically that is
very true mate - unless - of course - you use electromagnets - which they do use when power is not the issue
@@ThinkingandTinkering power is die issue unfortunately
So Rob, you mentioned about your plan for world domination. Are you a freemason?
33rd degree order out of chaos
lol - that mate is an unanswerable question lol
@@ThinkingandTinkering I bet you look smart in your masonic apron.
