Do a video on democratized energy solutions like solshare in bangladesh

I hadn't realised how much this technology had improved!

It would be great to see how the cost of drilling deep holes has changed over time, and how that's projected to impact geothermal. I can imagine cheaper drilling making geothermal economical in far more places. Low-carbon energy with 24-hour availability anywhere on earth . . . if you can just dig a deep enough hole. It could also be a good way to repurpose oil & gas drilling equipment.

I wonder if there is a way of combining kinetic and gravity storage into one device.

@sadimuntakim I completely understand. It's the same issue in my country zambia in africa...the fact that the technology exists is truly inspiring and the optimist in is look for opportunities in this area still...corruption still exists but we have to try to democratise energy distribution if we want to progress as third world nations

Would be cool to see a vid just on this video with flywheel start.

Transfer the investiment that has been pumped for the last 20 years in lithium battery technology and you gonna see the difference

Or maybe it’s a conspiracy

In the early days of electricity, Nikola Tesla and other inventors experimented with using flywheels to store energy in a mechanical battery of sorts. The idea was that the flywheel could be used to generate AC power on demand, without the need for a power plant or other external source of energy. However, the technology never quite caught on and was eventually eclipsed by other forms of energy generation. Now, nearly a century later, scientists are revisiting the idea of using flywheels to store energy. With advances in materials and engineering, it may finally be possible to make the flywheel-based energy system a reality. And if successful, it could provide a clean, renewable source of energy that is close to our goal of using a hamster for our energy needs.

The Dutch operated flywheel powered busses for a while in the 1980s/90s if I remember correctly.

Why is the price of install so high? Just transport of the weight?

I was thinking about the drag of the flywheel. The bike company Specialized came out with a three-spoke wheel that was insanely efficient. You had more drag turning a page in a book then that wheel spinning.

Magnetic bearings levitate the flywheel which cuts down on the drag too.

@@CashJohnston We had a combination of the magnets and helium

Definitely still worth it IMO. You obviously don't intend on the unit failing, and if it does you can just encase each one in the ground so if it does blow up it's contained.

These sort of carbon fibre rotor were gaining popularity in laboratory based centrifuges when I did my PhD in the late 80s. Worst case scenario failure of metal rotors (3 equal sized fragments) could cause the centrifuge to leap about the lab, of the fragments to exit the containment shield within, decapitating lab staff. With a carbon fibre rotor, if the rotor disintegrated, it did so explosively, but to form a very large ball of fluff.

Texas grid has been ruined by "green" energy. Texas is now number one in the world for rate of increase of wind power, due to massive subsidies undercutting reliable sources of power. Unfortunately, wind power output isn't consistent every day every hour throughout the year nor can it be scaled with demand like a natural gas plant that can simply increase or decrease power output by burning more or less gas. Unfortunately, the subsidies make it so cheap that it still drives nuclear and natural gas and other reliable sources of energy under displacing them on the grid. So now Texas that used to be so rich in energy is suffering warnings of brownouts and power shortages. They keep promising that batteries can solve this problem, but the fact is that no batteries exist that can economically store massive amounts of power, and many are extremely environmentally unfriendly when scaled up. So just like Hitler with his "wunderweapons" the left promises battery technology that is always "just around the corner" will solve the problems they create with out of control inflation, commodity shortages, excessive energy prices, and more. They never take responsibility for their actions.

@@boiibee2851 Fairymead. Did you work in a sugar mill, and which one?

The thing with a modern flywheel is that there is no need for extreme RPM, you just do the math, run it in a vacuum with a magnetic or some sort of low friction bearing and then figure out your windings to get the current that you desire. Just look at that antique Swiss bus, 6 kilometres at 50-60 km/h. spin it up when you are stopped for passengers and good to go. combine that with diesel electric for backup and our modern energy braking recovery and I can see this being at least 5x more efficient then it was 70 years ago. you can even have a direct mechanical transmission of some sort. when you look at 3000 lb battery pack in a Ford Lightning pick up truck that gives you a lot of inertia at 10x that weight in flywheels in a commercial city vehicle. Combining various energy recovery systems along with just keeping it spinning at top speed while it isnt in use would likely make it last even longer. Also you need no exotic materials, no fire risk, run it at a modest speed in a well designed case to contain any unlikely catastophic failure. It just sounds like a great thing as we have been using flywheels of all sorts for thousands of years (pottery, spinning yarn, wind mills, etc). You look at the massive turbines in hydro electric, the high speed steam driven power plants. It is just a no brainer to perfect what we know instead of looking for rare earths for a 10 year battery. We humans just seem to love to look for higher technology to make things more complex and try to make things "better" instead of looking at simple known tech and making it more efficient. Just look at the electronics supply chain problems, thousands if not millions of cars waiting on a microchip just to make them function but otherwise complete and ready to go. Imagine where we would be with modern transport if for example we could not make our autos run for the want of spark plugs 120 plus years ago.

Much like with trains, flywheels represent a simpler, older technology, that nonetheless does the job more efficiently than more complex technologies that have superceded them. And just like with trains, it would behoove us, as a society, to pursue more use of flywheels to help our climate and energy woes.

The elegance I see isn't just in it being singular spinning masses so much as the way it turns tensile resistance into power storage and means that any 'super materials' we create are also energy storage devices. A bit of a slight ulterior motive that probably applies in many cases is not having to consider chemistry directly as something nice, in the same way that being able to write code to filter numbers is nicer than having to spec out an analog filter. Even if it is technically less efficient in itself the ease and familiarity spares consideration of other approaches.

@@Nasrudith I love your analysis. We should also not forget that mechanical solutions of stored energy, be they kinetic energy or potential energy, have much longer service periods than battery solutions. And then there's the dirtyness of chemical production for batteries, before disposal. Changing bearings occasionally seems like a much better alternative.

To shutdown, you hold the decompression lever down and wait, and wait, and wait, and wait some more for it to stop turning. The generator, fan blade, and flywheel on the engine will rotate the engine for nearly 5 minutes and if you release it before it stops turning, it fires back up. At 1800RPM it varies only between 59.9 and 60.1 Hz under load. One of them running on UKposts. ukposts.info/have/v-deo/a4VmZpecjoGHlmQ.html It looks like it has the small flywheel on it.

@@lavaot5207 That would require one hell of a gearbox to turn probably about 10 RPM to 30,000/40,000 RPM, the mechanical losses would probably outweigh the potential electrical losses incurred by just directly wiring the flywheels into the output of the turbine

@@richardmillhousenixon You can use steel flywheels... And the power for the tubine already has a gearbox that does that (to generate electricity). I'm thinking that it would be too heavy

@@marshmellominiapple The gearbox that steps up the turbine rotation to the generator rotation turns about 10-20 RPM to exactly 3600RPM in the US (or any country with a 60Hz grid), and 3,000RPM in any country with a 50Hz grid. Still far below the 30,000-40,000RPM or greater needed for effective flywheel storage. And a solid steel flywheel would not be a good idea. Ideally you want a flywheel with a very high moment of inertia, i.e. most of it's mass at the edge, which would mean the best design would be something with a carbon-fiber hub and a ring made of some dense metal.

Dude it was obbiously destroyed by the power companies. They dont want people to know

Anything storing energy is going to be, well, full of energy. A flywheel going off-balance or coming loose is akin to a battery shorting out or catching fire. Flywheels are a viable energy storage medium, but preventing them from being a hazard seems like it'd need a quantity of what I think the pros call 'heavy shit' placed between the wheels and anything likely to be damaged by the wheel getting loose.

@@viron6734 Wow... The arrogance. You, some rando on the internet, are just going to casually dismiss the insights of the world's experts on this topic based on 0 data.

No. They would not. It’s absurd we are trying to go for wind and solar, instead of time and tested tech like nuclear. We are decades behind where we should be because of fear

@@jamesbizs Really? Very interesting. Nuclear energy is not only highly pollutant and dangerous, it's also incredibly expensive when you remove the SUBSIDIES.

Nuclear power is our only green future.

@@nandodando9695 Chernobyl and Fukushima ring a bell !?

A molten salt reactor using thorium is a solution.

i guess he mispronounced

Thanks for pointing that out. Seemed off to me, too

Yeah, I thought the same, you can't simply accelerate a high amount of mass in that time orders without wrecking some (if not every) component in the machine

In theory, a flywheel can be charged in the same time a gun is fired. One big bang of energy and the flywheel is humming, fully charged.

Requires only a trillion ton*miles of torque. So??? lol

They don't forget they just remember the big screwups of the past better

It's more about holding off on processes that might enable more weapons grade plutonium until we can get fusion energy.

Chernobyl, Three Mile Island. No one's forgetting anything.

K, What do you do with the spent fuel rods ? Yeah, dig a hole in your back yard .

@@crashoverride93637 Including those screwups it is still safest and most efficient technology.

If you have 2 flywheels spinning in opposite directions the forces will cancel eachother out

@@henkkees7753 does it also take into account horizontal/vertical alignment or just wich way it is spinning?

You are right about your moment of inertia comments, but I think Matt was intentionally simplifying his analogies so they would be accessible to a wider audience.

Unlimited cycles? They have magentic motors and also..they aren't made of diamonds everything tear out by time bro

@Frugal Family Living Thanks, that's what I was largely going for. I know I should have put quotes around "Unlimited cycles" but it is what it is. Plus you'd think a motor goes out, you swap out the motor and you're good to go again, batteries stop charging... you don't just reset their charge ability.

Sí existe la posibilidad pero cuando estén los materiales más desarrollados.

Oh I was wondering about that. The video didn’t mention how long they can retain their energy and a quick google search didn’t help either. Definitely sounded closer to a cap than a battery.

@@PHEEliNUX yes, on the other side a big lithium battery let's say the chem used in tesla cars also loses a lot of energy each day in these capacities.

Just as with those new modular nuclear reactors, you can scale flywheel storage systems by operating many of them in parallel. It is even possible to transfer energy from one module (flywheel) to the next to smooth out / equalize their load.

I'm not sure a magnetic bearing would need replacing, would it? No contact, no friction... What is there to wear out? Do permanent magnets degrade over time? 🤔

Permanent magnets do in fact wear out over time. Electromagnets too but much more slowly.

@@EleanorPeterson They last a long time. In 100 years they will only lose about 1% of their magnetism in proper settings.

​@@HELLO7657 steel (a ferrous metal) completely resists fatigue under a certain limit (I think it's 20 MPa). So we could make the load bearing part out of some steel alloy.

Sounds very interesting!!!!...I love the interest in this technology!!!👍😁😎

flywheels are kinda heavy

@@pasticcinideliziosi1259 not a high tech Kevlar one designed for vehicle use. The weight of this one was 100 lbs for the entire assembly. The flywheel was a Kevlar and epoxy form. Today, it would probably be carbon fiber, as well as the Vacuum housing.

On of the downsides of Flywheels energy storage for vehicles is that it is essentially a gyro, which resists motion. This means usually they make it really hard to steer.

Whatever happened to the Chrysler Patriot? Not the Jeep, the flywheel/turbine powered race car that ran on LNG.

Theoretically? Forever (--> Newtons first law)! Practically however, it depends on how well the flywheel unit is made: the tube has to be completely sealed and contain a near perfect vavuum, the bearing/maglev system has to induce as little friction as possible and the mass has to absolutely balanced. All of that is the reason those things can be/are so expensive - at least when you aim for a high efficiency. A rough estimate for current, commercially available flywheels systems for mass energy storage purposes is about 5% self discharge per day (Li-ion battery: ~2% per month). So to answer your question: it would take about two weeks for a fully "charged" unit to drop to

@@nicoj9984 thanks for elaborating on that. I had expected a much higher self discharge rate.

@@nicoj9984 it is high loss for long term, so it is good for daily use, many number of cycles

@@makantahi3731 In the context of grid storage, that's exactly what they are intended to do: They aren't meant to store huge amounts of energy for a long time, their job is to "smooth out the curve" of renewable energy sources over a short(er) period. They will, for example, store some of the energy a solar array generates during the day when there is lots of sunlight and then release it during the night when there is none. My area of (some) expertise however is the use of flywheels as uninterupted power supplies (UPS) for bigger datacenters: Here the main advantage of flywheels is that they can discharge their stored energy very, very quickly while chemical batteries are comparatively slow. So if you need lot's of power (Im talking megawatts) for just a few seconds to keep operations running until either grid power is restored or a buckup generator has ramped up, you would need a shit-ton of battery cells to deliver that much power at once - or you use flywheels and save a lot of money, space and maintenance.

Ha! It is the right system for sure ... but I'm American, so it's hard to remember that. 😉

@sadi muntakim they also beat their wives

if this was made by an american channel we would need to convert football camps into metres

@@pasticcinideliziosi1259 xD Same here in germany, there is a TV channel who is measuring everything in "soccer fields" - everything! :-)

Yeah, thanks Matt. I think there's a space between the number and the units though, but I've noticed in North America is usually not put in. Same as spaces instead of commas in long numbers. Thanks again for using metric like your military and NASA uses!
