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 - ua-cam.com/video/nbpJZnLfe4k/v-deo.html
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.
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.
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?
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 :)
@@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.
@@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.

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 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.

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.
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.
@@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

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

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

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!
Thank you so much for pointing it out, not sure how I looked past that. I appreciate your comment!
Try new idea hydraulic system drive to the flywheel and create huge amount of kinetic energy contineusly
Really interesting: Why don't they apply the Flywheel Battery to charge electric cars?
hybrids as well could recharge batteries or trickle charge …. could be part of braking inertia…

I was wondering how the flyweel energy storage systems works.
I hope the video explained it good enough :)

Hello there, how come noone thought of the second oldest mechanical battery that is the MAINSPRING. Like those in old-fashioned clocks....
That’s a good question, I’ll do a bit of research and maybe make a video on it. Thanks for your comment!
But doesn't Earth rotation kinda drain power from flywheel? Should they be aligned to counter spin and precession of the Earth?
Thanks for your answer @BI7L!
@BI7L Gravity? Sorry - I don't understand what kind of relation between rortation and gravity we are taking about?
Not in the case of my designs the axis of earth is orthogonal to the Gajjar Mechanical Battery
Earth's rotation is slow

Is there any commercial FlyWheel battery that someone can buy today? 500KWh to 1.5MWh. Would be enough
I'm not sure if there are any Flywheel batteries commercially available on the market yet.
clean straight forward video! awesome graphics as well
Thank you for your comment! It means a lot
Temperature wouldn't really effect a flywheel, would it? One could be installed outside and used as storage for solar . . ? 🤔
Losses probably faster than the charge
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.
In the mid 50's there was a bus (Gyrobus) that operated on the very same principle.
@@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.
i read that many subway station uses that tech already
