The Mechanical Battery: How Flywheels are Changing the Game

[@GeniusEngineering]

What do you think of Mechanical Batteries? Any other technology I should look into? Be sure to check out my video on Solid State Batteries - kzbin.info/www/bejne/pJPTe42kgcuYas0

[@otkirbektoshboyev6935]

That's like capacitor, it's better calling that device mechanical capacitor. ?

[@MultiMenvafan]

I think flywheels make a lot of sense to adress the intermittency of a renewable enercy mix, it is tried and tested over centuries unlike some odd gravitational bettry prototypes. The key IMHO is to think about energy density vs weight. In an electric car the sheer weight of a flywheel means it can't compete with a chemical battery. But for utility scale, decentralised energy storage it's perfect, isn't a problem if it is stationary.

[@KyrychenkoAnton]

There's 1 thing particularly interesting for me with flywheel batteries - how long can they store the charge? Say if I spin it to 1kW storage speed - how much of 1 kW will left after 1 month percentage wise? It should lost momentum sure, but how fast?

[@GeniusEngineering]

The idle losses losses during storage is one of the biggest disadvantages of this tech, they lose energy to quickly to be used for long-term energy storage, and there is still a significant barrier that needs to be overcome before the flywheel technology can solve the task of storing renewable energy. This is why they are mostly used for short duration applications where they can operate a few minutes up to a maximum of an hour. Superconducting bearings will be a game changer as the reduction of friction losses is the main focus of research and development for flywheel systems, since it enables increased rotating speeds and decreases self-discharge rates. I hope this bit of info helps to answer your question :)

[@KyrychenkoAnton]

@@GeniusEngineering Thanks a lot for explanation!

[@GeniusEngineering]

You're welcome. Thank you for your comment!

[@merlijn5467]

@@GeniusEngineering Note that this is one side. In normal application the flywheels are constantly being powered with an efficiency of 95-98% when rotating at an equilibrium. They only spin down when the energy stored in them is actually needed.

[@DreamingConcepts]

@@GeniusEngineering it is already used a lot for grid systems and self-discharge have been already reduced a lot using magnetic levitation and vacuum to reduce all losses. I think BeaconPower said their flywheels only self-discharge for about 0.1% per month, which is more than perfect for homeowners and microgrids.

clean straight forward video! awesome graphics as well

[@GeniusEngineering]

Thank you for your comment! It means a lot

[@-ALPHAMAN]

Yes this is the fabulous explaination I ever seen make more like this

[@GeniusEngineering]

Thank you for your comment! Glad to hear it was informative.

[@OutRAjious]

Don’t use electromagnets for the bearings use natural magnets , both pole to north … save electricity!!

[@crosshairs007]

Magnetic bearings are subject to large demagnetization fields and break down. Electromagnets solve that problem but require energy use. Which is better? Depends on what your engineering requirements are.

[@djt6fan]

One sidenote, the energy efficiency formula at 3:00 is wrong, should be the other way around, E_out over E_in. Other than that, very informative!

[@GeniusEngineering]

Thank you so much for pointing it out, not sure how I looked past that. I appreciate your comment!

[@okithdesilva7644]

I was wondering how the flyweel energy storage systems works.

[@GeniusEngineering]

I hope the video explained it good enough :)

[@ehaurader2640]

Wow another base foundation technology Going hard man I like the fragility of electronics And the reason is pretty cool

[@GeniusEngineering]

Glad you enjoyed the video!

[@MrNelsonhsieh]

The flywheel power storage can be used for the power supply of the tram. When the tram decelerates, the flywheel is used to store power. When the tram accelerates, the flywheel supplies power to the motor.

[@GeniusEngineering]

In the mid 50's there was a bus (Gyrobus) that operated on the very same principle.

[@DreamingConcepts]

@@GeniusEngineering the difference is Gyrobus was powered only by the the flywheel, recharging it on each bus stop. Just imagine having not only no air pollution, but also no electro-magnetic pollution from electricity as it required no electricity.

[@Spider-Too-Too]

i read that many subway station uses that tech already

[@mrtriathlondude]

@@DreamingConcepts electromagnetic pollution isn't a real thing.

[@muratahmetgenc6942]

with the new materials, nano-technology, it can be better and cheaper than batteries in near future! great video, thanks!

[@GeniusEngineering]

I agree a 100% with you. Thank you so much for your comment, glad you enjoyed the video!

[@gianfrancopurpura8112]

Really interesting: Why don't they apply the Flywheel Battery to charge electric cars?

[@OutRAjious]

hybrids as well could recharge batteries or trickle charge …. could be part of braking inertia…

Thanks Again Great Video

[@spiderpickle3255]

Temperature wouldn't really effect a flywheel, would it? One could be installed outside and used as storage for solar . . ? 🤔

[@kinbolluck476]

Losses probably faster than the charge

[@tvinforest5255]

But doesn't Earth rotation kinda drain power from flywheel? Should they be aligned to counter spin and precession of the Earth?

[@GeniusEngineering]

Thanks for your answer @BI7L!

[@tvinforest5255]

@BI7L Gravity? Sorry - I don't understand what kind of relation between rortation and gravity we are taking about?

[@BHARGAV_GAJJAR]

Not in the case of my designs the axis of earth is orthogonal to the Gajjar Mechanical Battery

[@Bleepbleepblorbus]

Earth's rotation is slow

[@prostotack819]

Ребята поинтересуйтесь работами ученого Нурбей Гулия , он сделал много практических работ в этом направлении .

Un vídeo excelente 👍🥂🎩

[@mbrunoferreira6756]

What is the status (TRL) of this technology? What's the mean cost (MWh/Eur) one can achieve with this? And what's the capacity (MWh) available with usual examples?

[@petrurazvanvasi9450]

Hello there, how come noone thought of the second oldest mechanical battery that is the MAINSPRING. Like those in old-fashioned clocks....

[@GeniusEngineering]

That’s a good question, I’ll do a bit of research and maybe make a video on it. Thanks for your comment!

[@Lasfrans]

Baie goeie kwaliteit video. Dankie vir die deeglike verduideliking. Sterkte met jou toekomstige videos.

[@GeniusEngineering]

Dankie vir die comment Carlo! Dit beteken baie.

[@yogeshkrishnan7157]

I learned that flywheel is used in vehicles to reduce fluctuations of energy. For those that have Engines because they deliver power in only one stroke. But why do we need flywheel in Electric Vehicles other than the mechanical battery purpose. Since electric motors deliver a constant power.

[@stevengouws8684]

Excellent boeta ! Very well explained, thank you. Sub'd.

[@GeniusEngineering]

Thank you for your comment Steven, it means a lot!

[@amador1393]

Try new idea hydraulic system drive to the flywheel and create huge amount of kinetic energy contineusly

[@skunksville]

Would be nice to have an electric vehicle with a projected lifespan of decades.

[@GeniusEngineering]

You rock!

[@DwAboutItManFr]

Why no passive magnetic bearings?

[@Sol-En]

Because bearings based only on permanent magnets can`t be stable. It is use some times complex bearings with permanents and active magnets. Then the electric consumption become less. Also can be used bearing on super conductor base, but then you will must to spend electric energy for super conductor cooling.

[@GeniusEngineering]

Thanks for the explanation!

[@DwAboutItManFr]

@@Sol-En But they do exist, i assume the spin stabilizes it or diamagnetism perhaps.

[@Sol-En]

@@DwAboutItManFr Yea that`s true. I think, that it is hard to do electric generator with spin stabilization, because you need quite little gap between rotor and stator for effective work. It is impossible to achive such little gap with only spin stabilization. Diamagnetic forces quite weak , so it is also difficult to do i think. Main general problem of passive sistem is no vibration supression, and as result big vibration :) So active element unfortunatly must be i suppose

[@Sol-En]

​@@GeniusEngineering And thank you for video. Videos like that are very important for our civilisation, because they are enable beginner and advanced engeneers to learn faster and with more pleasure. And also for Russians like i am it`s very helpful for English learning :)

[@grahamflowers]

There is no kinetic energy in a moving mass there is force Mv squared kinetic energy is the energy of consistent work from a consistent force regards Graham Flowers MEng

[@jfbaro2]

Is there any commercial FlyWheel battery that someone can buy today? 500KWh to 1.5MWh. Would be enough

[@GeniusEngineering]

I'm not sure if there are any Flywheel batteries commercially available on the market yet.

[@KOl-xj4jt]

it's huge galactic demand more than billion trillion market

[@jfbaro2]

Is it noisy?

[@joelsoncdma]

friend if the quantum lock be invention? (false). what you think about? The nitrogen freezed Aether nearest magnetic poles inside material...think in this (the material now is magnetic ) AETHER CAN BE PROVED (true). {isso explica porque o imã pode girar em seu eixo magnético...em supercondutividade isso não deveria ocorrer [variação do campo magnético geraria Ed corrent (fomos enganados)]}. Congratulaitions! like you!
