ROFLMAO, you need a puns per minute metric 😂

We learned about the oldest versions of these.

Old emergency generators used MASSIVE steel wheels for their emergency power system attached to a deiseal engine. Generally they are expensive to start up, but VERY cheap to keep going once they got up to speed. I had always wondered why we never continued to invest and expand in these systems.

I think this with the Silica power storage systems that I think you mentioned in a video once upon a time make sense together. In places where Hydro electric is available I can image you could partition off parts of the grid so that black outs from inclement weather.

I think a lot of people get hung up on a single answer to our energy deficient problems…. I also think burying these in the ocean is a REALLY good idea. The main problem of what happens if this catastrophically disassembles it's self and the others stationed near it, is neatly dealt with by water's ability to swallow kinetic energy.

Bring the song back

I can see fly wheels becoming standard components for solar and wind. It'll just be another part that is taken for granted because it is so useful and obvious after the fact.

Matt is on a roll!

This is just another gimmick funded by taxpayers at the pleasure of ignorant government officials, paying off the cost of their campaigns by handing out contracts with kickbacks.

China and green energy? Hahahahahahaha! Considering the waste they make in process of all of their production… green energy sounds like joke!

In the seventies I was shown an huge and at that time seemingly ancient flywheel that was used as a power filter. Power in went to the motor. On the other side a generator was constantly running. The result was stable power without voltage spikes.

This sounds more like voltage regulation than energy storage. It takes energy to get them going and more to keep them going. The way it’s explained in the video doesn’t explain how this is beneficial. It reminds me of those videos where they hook up an alternator to an electric motor and claim it’s endless energy 😂

Watching this just gave me an idea though. One application that I think could truly benefit from flywheels would be in outer space. A space station takes in solar which would power the flywheel starter and give it small boosts only when rotation slows below a certain threshold. Being its in zero G I would imagine that it wouldn’t slow that often and could output more power than the solar panels would take in over a years time. Plus if implemented correctly it could also act as a stabilizer

Thumbs 👍 interesting

Ultimately you're wanting 50Hz / 60Hz (depending on the country you live in), I wouldn't be surprised if they didn't just rectify whatever high frequency AC is coming out of the flywheel to DC and then use an inverter to convert it back to 3 phase AC for sync and frequency. Frequency and phase matching is incredibly important to prevent failures at generation sites or loads.

A generation site can get disconnected if phase and frequency aren't closely matched to the load in order to prevent damage, but if a generation site (or sites) are disconnected, the remaining connected sites are now under more load, and that causes them to get further out of sync, exacerbating the problem, which leads to wide spread failures unless the load can be shed (ie forced blackouts), or more generation can step in at phase and frequency, and return everything to normal. If every generation site is knocked out, that leads to a 'black start', which is pretty complicated to recover from as something needs to provide the clock (or frequency) that sites are synchronised to, and it also requires bringing the areas disconnected on in stages to prevent everything from rapidly falling out of step again.

Or, we could just install (more?) nuclear and avoid the complication of storage atop synchronisation, at least until the fusion nut is cracked. In my mind, flywheels are a good solution for sites to have something to provide power while diesel generators come online in case of a blackout, and this is exactly how several datacentres I worked at did things (and that was old tech 20 years ago), but trying to make this small scale solution fit for large scale seems like elimating the problem with more reliable generation to start with is smarter. The turbine at a nuclear/coal/gas plant will have an integrated flywheel rotating at the same speed as the turbine/generator to smooth out sudden changes in load, and permit a bit of time to change how much heat the fuel produces and is centuries old tech.

An unpopular opinion, I know, but I see these products as being useful only in specific scenarios, at large scale it seems like a waste of resources.

I feel like most of this video is wrong or intentionally misleading. How could you power the grid from a flywheel without that flywheel "spinning down", i.e. converting rotational speed to electrical power, without expensive, lossy, and complex AC->DC->AC systems? This video would benefit from an actual comparison of total system efficiency, lifetime ownership costs, cost per MWH storage etc etc. No way those things can spin for a decade+ without maintenance. And magnetically levitating a 100+ ton weight to increase frictional efficiency versus a rotor? Are you kidding? What was the comment on carbon fiber anyway? Do you have anyone review these videos or is this script AI generated?

wouldnt there be a threshold regarding radius? The bigger the more energy efficient and the more energy it can store…maybe.

could a large amount of flywheels around the world have any effect on the planets rotation?
I ask because of the "resistance" you feel when holding a spinning gyroscope… they're just flywheels after all.

Do flywheels have to be aligned to the earth's axis to avoid precession forces?

Ahh the puns you had fun with this one..
