Super Flywheels - New Energy Storage Batteries

1.7 MW of power is 472 kWh. To take away such power, first pump it. So there will be an electric engine with a capacity of 100 kW to spin the super-flywheel for 4 hours 45 minutes.

In winter, sat down and went? Directly to the landfill, because the oil was frozen, and the super-flywheel simply tore the pump, crankcase, oil lines. Or will the flywheel heat the oil?

Not a container of 17 tons, but a flywheel. Since the flywheel of less weight will gain 1.7 MW at revolutions that are many times higher than permissible for reasons of mechanical strength of the flywheel.

Is there no gyroscopic effect? This is something worthy of the Nobel Prize!

tuan, all problematic issues described by you are solved. Read Gulia himself and you will understand that a super-flywheel is not just someone’s fantasies, but a real invention (by the way, the invention of a Russian scientist, which is also very important), which, with active popularization and widespread adoption, can simply turn over many things that are familiar to us.

One is more beautiful than the other, I'm in a stupor from this.

Alipapa, sure, but somehow I read and didn’t even notice. Cool joke.

Flywheels can get extra power. This fact was proved back in 1998 by Jakob Bitsadze. But the well-known Tariel Kapanadze ringed his technology as his on all TVs in 2001.
On the basis of this know-how, dozens of machineries have been created all over the world - although the name of the present author is hushed up.

Sometimes smart things are written. And here ...... A flywheel weighing 17 tons, is a big drill! And cars are not modest. What will this colossus spin on? Bushings? Bearings? Power losses due to forced lubrication, friction ..... Converting electrical energy to kinematic, and then back ... Perhaps the use of such units in powerful power plants is justified, as compensators for fluctuations in day-night consumption, all one energy disappears. ... "all the problematic issues described by you are being resolved," there is no dispute, they are being resolved, but there is still no perpetual motion machine.

Flywheel? Models of such cars are familiar from childhood. These are inertial toy cars. We spin the wheels to a "pleasant" screech in the gearbox. Then let on the floor. The machine rushes forward briskly. However, toys with electric motors and batteries are somehow more pleasant and maneuver for a greater distance with the same weight. What is the advantage of a flywheel in transport? Save the energy flywheel, of course it can. However, the question is how much the flywheel will weigh and at what speed it will spin to give the same energy as a gas tank with a capacity of 100 liters?
What happens if a machine with a flywheel gets into an emergency? It is possible that a flywheel will fly out of it with the speed of an artillery shell, crashing all along an unpredictable trajectory is much more effective and at a greater distance than a gas tank explosion with the same energy reserve.

A super-flywheel is a drum that is made of composite materials, for example, wound from thin turns of steel, plastic tape, fiberglass or carbon composites. Due to this, high tensile strength is ensured. To reduce friction losses, the super-flywheel is placed in a vacuum casing. Magnetic suspension may be used. The super-flywheel can rotate for a very long time with minimal losses, in addition, it is completely safe, since a tape disk is used. The super-flywheel is capable of storing and giving energy. To do this, a motor generator is created, where the stator is the drum, and the rotor is the axis around which it rotates. Thus, when connected to the network, it will store energy, and when connected, the load will be given. The efficiency of this conversion reaches 98%. N.V. Gulia himself saw the main area of ​​use of super-flywheels in transport.

Heavy stationary super-flywheels are produced by the American company Beacon Power. They are made of a large number of layers of carbon fiber composite and untwist 22.5 thousand revolutions per minute. On the steel shaft of the flywheel, inside the sealed steel cylinder, there is a rotor of a reversible electric machine - a motor-generator (it is made with permanent magnets), which spins the flywheel when receiving energy and generates current - when the load is connected. Such super-flywheels weigh together with the container in which they are more than a ton.Sets of many such drives connected in parallel can absorb a decent amount of energy, but the main thing is that they can do it very quickly, as well as return the accumulated just as quickly.

This is how it all looks:

There is a project of an 18-ton super flywheel (weight with container) containing 10 Smart Energy 25 flywheel drives with a total continuous power of 1 megawatt (for a short time, several minutes, and up to 2 megawatts - this is the power that can be absorbed by it or generated) and with stored energy - up to 250 kilowatt hours.

Thanks sincerely for the comments! I must say right away - I'm not an electrician. Maybe that’s why a lot of things voiced by me to some experts will seem like wild fantasies, but this is not so. For more than 20 years I have been seriously interested in the history of inventions, inventors and everything related to invention. N.V. Gulia has been familiar with the ideas and works for a long time and even then he saw a gigantic prospect in the widespread use of his supermoveer. The facts I cited about American super-flywheels are taken from open sources. Google Chrome to help you - there is an automatic translation function for those who do not know English. I myself will not argue with anyone, because in a dispute, alas, truth is not born. This is a common misconception. Read the source.
3 more of my notes have already been published on this site: “How to Save Electricity Comfortably” and about the lamps of the great Russian inventors P. N. Yablochkov and A. N. Lodygin. Now, at the request of the site’s administration, I’m preparing a couple more things. If this is interesting to you, take a look.

Vitaly Are you not an electrician?
And the topic does not apply to electrical engineering, it is mechanics, the dynamics of rotational motion. The topic does not apply to violent fantasies. It is quite possible to use the flywheels for the accumulation and return of energy (recovery). The efficiency of such recuperators is higher than that of electric batteries. In stationary installations, this method of energy storage is justified. There are other ways to store mechanical energy, for example, pumping water into a reservoir during a period of minimum power supply, followed by descent to a generator turbine during a period of maximum load. The efficiency of such a recuperator is lower than that of a flywheel, this is undoubted. However, the applicability of flywheels located in vehicles is doubtful.
Here it is necessary to consider - where is more energy per kilogram of installation weight? - in a flywheel that fits in a typical truck or bus or in a gas tank with an internal combustion engine of the same weight? Even if the efficiency of the flywheel approaches 90 percent (which is also doubtful), and the efficiency of the internal combustion engine is 50 percent.

A super-flywheel is not an ordinary flywheel, as it can spin up to much higher speeds without the risk of bursting with the strength of an aircraft bomb. N. Gilia placed the super-flywheel in a capsule without access to air, thereby removing friction against the air. In addition to bearings, powerful magnets support it, and there is no longer friction. Therefore, such energy storage devices can work for several days. A flywheel is better than a battery, since it can give up all the power almost instantly and turn it into work, or electricity. And just as quickly accumulate, taking yourself too much power, for example, in the grid.

For a long time, all the cars drove only on internal combustion engines, and no one tried to think differently. Although some attempts were to create machines on electric motors and batteries. But they were expensive, heavy, environmentally dirty and with low mileage without recharging. And they charged for a long time. Therefore, they were less effective than gasoline analogues. Yes, now the situation has changed.Compact and powerful electric motors, large-capacity batteries, as well as electronic control systems for all this, and saving up to a third of electricity, have appeared. But all this did not give mass demand for electric cars, and hence the release of such cars. And only thanks to the practical implementation of super-flywheels, electric cars will be able to begin to conquer the world, since the super-flywheel is a universal energy storage device!

With a super flywheel, an electric locomotive and sea transport can drive without polluting the atmosphere. And one such super-flywheel can save half the fuel in buses and trucks! America, as always, stole our Russian development, because Russian scientist N. Gilia invented the super-flywheel back in the sixties of the 20th century! In America, they are used to smooth out power surges. At the same time, they did not pay us a dime. But in fifty years you could do everything yourself. They did not wait when we do it! And we can produce them - patents - then ours.

P.S. A practical example of using a super flywheel in transport is given in one of the articles previously posted on this site - Hybrid with a super flywheel and a supervariator.

Super accumulator found! It is called SUPERmahovik! It’s so breezy ... Yes, and created by a Russian scientist! Hurray comrades !!! - the patriots shout ... I would certainly like to believe, but somehow more like a fairy tale.

In fact, in some ways the author of the article is right. I don’t know exactly who owns the idea of ​​using a super-flywheel - I don’t consider it important. But the fact that this idea, although not problem-free, but not rotten, is a fact.

When I was studying at the department of electric drive and electric transport at our local technical university, we had one lecturer in the rank of associate professor seriously ill with the topic of a super flywheel for transport. He collected examples of its successful use and, in fact, proved that this idea is very good. It’s just not the time, and lobbying for their interests by oil tycoons and everyone who is tied to the circulation of oil products does not contribute to new ideas for the development of electric transport.

Therefore, a super-flywheel is not funny fantasies in any way, but the fact that the author of the article made some mistakes and inaccuracies does not change the essence of the matter.

The article seems doubtful, since the author is technically illiterate. In fact, megawatts do not measure energy, but power.

Captain obvious? This is all noted.

The history of inventions is, quite often, the history of the overthrow of seemingly unshakable achievements, phenomena ... The rational grain is felt, but what about the gyro effect, which will certainly take place in transport. Even with static placement, devices with such kinetic energy of rotational motion will be subject to a gyro effect, because the Earth also moves, making two rotational movements !?

Alex, I say that the idea is sound in itself. Implementation is not yet at the level. If these developments were funded as they should, then the idea would have long been developed. And this applies to both Erefii and Pindostana equally. One hope is for the Chinese. There are no problems for them.

The flywheel, it seems to me, is very promising in alternative energy. Today they use batteries that, after fully charging, do not "take" energy from a windmill or from a solar battery, thus free energy is lost. But the super-flywheel has a wider range of stored energies, and, apparently, more stable relative to the level of stored energy efficiency. after all, it’s harder to charge it “to the eyeballs” - and this is its main advantage.Young - go for it and come to an end! :)

So, that is, if I wash down a house with a roof made of solar panels with a sticking out wind mast, and bury such a super-flywheel instead of hemorrhoid batteries in the basement, will I save energy and love and honor from the "green" ones?
Hmm, well, as soon as a kilowatt per hour costs 9 rubles in Germany, and not our 1.6 rubles, I’ll start thinking about it;)

I also thought about using a super-flywheel battery paired with a wind turbine. Here the plus is that the wind turbine gives out mechanical energy, and the super-flywheel accumulates it. Here, converters to electricity and vice versa are not needed at all. Here you just need to adapt some kind of mechanical transmission from the wind turbine to the super-flywheel and that’s all. And only then can you remove energy from the super-flywheel, converting it into electricity, and then when you need it.

I’m not sure about the super-flywheels, but the inhabitants of the past did not believe in much of what surrounds us and laughed!
P.S.: The article reminded me of a salesman who is trying to bet!

Nothing that, among other things, this flywheel will have a gyroscopic effect, as a result of which its (flywheel) efficiency is a big question. Except for straightforward movement.

Nobody writes that a single flywheel weighing 17 tons will solve absolutely all problems. You yourself might think that for a drill the flywheels will be smaller, for cars more, and for accumulating power plants even more.

Spin, i.e. spin, this colossus will be on a magnetic suspension, which has been used in high-speed trains for 100 years already for lunch. Hence the absence of losses due to forced lubrication, friction, and other delights. Even air friction is minimized by the discharged inside the housing.

Hence the high conversion efficiency.

Regarding the use of the flywheel in transport - this is a big question, there are already quite a few shortcomings voiced. But for stationary applications - there is a solution that is implemented and completely used. These are guaranteed power systems. As long as there is voltage on the line, the electric motor spins the flywheel, and a generator is on the second end of the axis. All critical equipment is powered by this generator - here the plus is that the generator gives a pure sinusoid, and a stable voltage, provided that the flywheel rotates at a constant speed, i.e., does not depend on what is supplied from the substation. In the event of a power failure from the outside, the flywheel is capable of delivering energy to the generator for a certain time, depending on its mass, radius and speed of rotation, until, say, a diesel generator starts or switches to a backup line. At the same time, the power delivered can be almost any - at least 10 kW, at least 200 - it all depends on the generator power and the energy stored by the flywheel, which compares favorably with conventional uninterruptible power supplies, since inverters designed for high currents are very expensive.

And this idea is not new, older colleagues said that they had seen such constructions at Soviet television centers, long before the UPSs that became now classic in general were widely used.

A couple of hours ago, I discussed this new topic for me (but it turned out to be worn down to holes ....) with a person who was, say, about 15 years ago, in one of the transmitting centers of ultra-long-distance communication and saw there one of the country's “uninterruptible”Tips, everything as described by the previous commentator: generator-flywheel-electric motor, the supply of mechanical energy should have been enough before starting the diesel generators (I think with a large margin ... in time). Funny in flywheel material !!! Granite. The difference in tensile strength, carbon fiber and granite is large enough to believe in this fairy tale (is it a fairy tale?) ...
