When it comes to what is necessary as-that to save energy, many immediately start thinking about the battery. Of course, what else could it be. However, there is another method, which is used not very often, but it has very good prospects. Especially against the background of the development of other technologies. Such development was used in the production of public and freight transport. Their origin has its roots in the Soviet Union, but recently the technology begins to be used more often. A few years ago when the rules allowed, it was used even in Formula 1. Open the veil of secrecy and explain how it works is quite simple, but brilliant invention, and the person who has devoted your life to.
What is the flywheel?
Say today we are going on the super flywheels and their Creator Norbee Gulia. Though it seems that the flywheel is something outdated and purely technical, but in the new electric world it is the place.
Themselves wheels were invented a very long time and even has been successfully applied in industry in those years. There are even discoveries in Mesopotamia and ancient China, which confirm the use of such devices. However, then they were made of baked clay or wood and perform other functions.
Where applicable flywheels?
Due to its massiveness and the laws of physics that accompany the movement of the flywheel, it has found application in many modern arrangements — from transport to industry.
The simplest application consists in maintaining the speed of rotation of the shafton which you installed the flywheel. This may be useful during operation of any machine. Especially in those moments when it is subjected to sudden loads and to prevent falling speed. Turns out this kind of damper.
Perhaps the most common place where there are wheels, is the internal combustion engine of the vehicle. It allows to keep the rotational speed of the engine when the clutch is. Thereby reducing the effect on the transmission as the gear change comes at a time when the engine is running at speeds above idling speed. In addition, this achieves greater comfort and a smoother ride. However, race cars the flywheel is very much easier to reduce weight and increase the speed at which it spins the engine.
Also flywheels are often used to stabilize the movement. This happens due to the fact that the wheel, which is the flywheel, the rotation creates a gyroscopic effect. It creates a strong resistance when you try to tilt it. This effect is easy to feel, for example, to promote Bicycle wheel and trying to tilt, or picking up the hard drive.
Such power interferes with the management of the motorcycle, forcing him to resort to countersteering, especially at high speed, but very helpful, for example, to stabilize the ship during pitching. Also hanging a flywheel, and given that he is always in the same position relative to the horizon, you can fix the deviation of the object body and to understand its position in space. The use of such properties of the flywheel is important in aviation. That is rotating the flywheel will allow to determine the position of the fuselage of the aircraft in space.
The Super Flywheel Gulia
Now, after the long introduction and background, let’s talk about the super flywheels and how they help to save energy, not having any chemical compounds for this.
The super flywheel is one of the types of flywheels designed for energy storage. It is specially designed to accumulate as much energy as possible without the need for another purpose.
Such flywheels are heavy and spinning very fast. Due to the fact that the rotation speed is very high, there is a risk of dilution of a design, but it is also designed. The flywheel consists of wound coils of steel or plastic ribbons of composite materials. Except that this design is stronger than solid, it still collapses gradually. That is, when peeling off the flywheel just will be slowed and confused in their own parts. I do not need to explain that the gap of the flywheel, which rotates at a speed in the tens of thousands of revolutions per minute and weighs dozens of pounds, fraught with very serious consequences.
In addition, to provide even greater security, you can put system with such a flywheel in bronekapsuly and bury it several feet in the ground. In this case, the moving elements accurately will not be able to harm humans.
An additional advantage of using bronekapsuly will be the creation of a vacuum therein, which will significantly reduce the impact of external forces on the movement. Simply put, so it is possible to minimize or even eliminate the resistance of the gaseous medium (normally air).
As additional forces that prevent rotation, another is the resistance of the bearings installed on the flywheel. But it can be installed on the magnetic suspension. In this case, the impact force reduced to such a minimum that can be neglected. It is for this reason, these wheels are able to spin for months. In addition, the magnetic suspension allows you to not think about the wear and tear of the system. Worn only a generator.
It is the generator and is the element that allows to produce electricity. It simply connects to the flywheel, and getting transferred to them by the rotation generates electricity. It is an analogue of the conventionalbut it is not necessary to burn fuel.
For energy storage at a time when there is no load, the flywheel spins up and thus “hold a charge”. In fact, the possible and the combined variant by analogy with the standard battery, which can simultaneously deliver power and recharge themselves. To promote the use of flywheel motor-generator, which can spin the flywheel and to steal the energy of its rotation.
Such systems are relevant for energy storage in households and in charge. For example, such a system on the idea of the Skoda engineers should be used to charge cars. The day the flywheel spins up and in the evening gives the charge electric vehicles without burdening the city in the evening and at night. You can charge slowly from one flywheel or quickly from a few, which will “shoot” more electricity.
Effectiveness super with all their seeming archaism reaches very high values. Their efficiency reaches to 98 percent, which is not even dreamed of conventional batteries. By the way, the self-discharge of such batteries is also happening faster than the speed loss of a well-made flywheel in a vacuum and on magnetic suspension.
You can remember the old days when people began to store energy by means of flywheels. The simplest example is Potter’s wheels, which spun and twisted, while the craftsman worked on another vessel.
We have already identified that the design of the super flywheel is quite simple, it has high efficiency and is relatively inexpensive, but he has one drawback, which affects the efficiency and stands in the way of mass adoption. More precisely, such two thumbs up.
Chief among them will be the same gyroscopic effect. If the ships is a useful side property, on road transport, this will greatly interfere with and it will be necessary to use a complex suspension system. The second drawback is the fire hazard in case of destruction. Because of the high rate of destruction even composite flywheels will allocate a large amount of heat due to the friction on the inner part of the bronekapsuly. On a stationary object it will not be a problem as you can make the sprinkler system, but transport can create a lot of difficulties. Moreover, transport the risk of damage is higher due to vibration during movement.
Where applicable, super flywheels?
First and foremost, N. In. Ghoulia wanted to use his invention that is in transport. Even built several samples that were tested. Despite this, the system next tests go. But the use of this method of energy storage is found in another area.
So in the United States in 1997, Beacon Power has taken a big step in the development of super for their application in power plants on an industrial level. These super flywheels can store energy for up to 25 kWh and had a capacity of up to 200 kW. The construction of a power plant of 20 MW began in 2009. She had to level out load peaks on the electrical network.
In Russia too there are similar projects. For example, under the scientific supervision of N. V. Gulia company Kinetic Power created its own version of the stationary storage of kinetic energy on the basis of a super flywheel. A single drive can store up to 100 kWh of energy and provide power up to 300 kW. The system of such flywheels can ensure the alignment of daily inhomogeneity of the electric load of the entire region. So it is possible to completely abandon a very expensive pumped storage plants.
It is possible to use super and where necessary independence from power grids and backup power. These systems have a very high response speed. It is literally a fraction of seconds and enables you to provide truly uninterrupted power.
Another place where you can use the super flywheel is rail transport. The braking of the trains spent a lot of energy and, if not wasting it by heating the brakes, and spin the flywheel, the stored energy can then be spent on a set speed. You say that the system on the suspension will be very fragile to transport and they are right, but in this case we can talk about bearings, so as to store energy for a long time is simply not necessary, and the loss of bearings will not be so big at that time. But such method allows to save 30 percent of energy consumed by train movement.
