In the past few months, ads have been found everywhere on the Internet that offer to buy an energy saver. Allegedly, it helps to reduce electricity costs several times. This is a tempting prospect. But are the promises true?
Advertised Principle of Operation
Aggressive advertising and slightly suspicious sites offer to buy a modern energy saver. Reviews on them say that with the help of the device, buyers began to receive invoices with sums 50% less than before. At a time when all utility bills tend to grow, such a device becomes simply indispensable.
The advertisement says that to save money, just plug the device into a free outlet closer to the electricity meter and no longer do anything with it. He will work for your family budget.
The device somehow starts to affect reactive energy, which is full in the mains and which significantly increases the level of electricity consumption by household appliances. At this point, the saving begins, which provides an energy saver. Reviews of experts on this subject are not so colorful. They not only negatively relate to the device, but in scientific terms they argue for this.
Recall Physics
Even with minimal knowledge from the field of physics, anyone will understand that the energy saver Econor and its analogues are complete nonsense that is completely untrue.
Let's recall some points. If we take the base and wrap it with an insulated wire in several layers, we get an electromagnetic coil. When a direct current passes through it , an electromagnetic field will appear around it, directed away from the coil.
This effect is used in all electric motors in which a moving element is placed in the field of action of the coil. This is how electric drills, hair dryers, and vacuum cleaners work.
But at the moment of current interruption, the coil produces the opposite effect, and some reactive charge of energy returns from it through the conductors. He disappears without a trace, overspending electricity.
Recall also that in the sockets we have an alternating current, which is interrupted 50 times per second. This means that motors create reactive electricity almost all the time, which is affected by an energy saver. Reviews of grateful buyers on the seller’s website suggest that it is very profitable. And the forums have a completely different attitude to this device.
Reactive energy sources
As mentioned earlier, reactive energy is generated by an electromagnetic coil. But for most people, it remains unclear exactly where these coils are located in their house. It is extremely simple: in almost everything that has a rotational element. In the kitchen, these are blenders, food processors, meat grinders, microwave ovens, refrigerators. In other rooms there are also hairdryers, vacuum cleaners, various power tools.
But that is not all. The TV also has its own coils, but they perform a slightly different function there, which does not make sense to describe here. Also, coils are in gas lamps, and now most of them are used in apartments.
So every home has enough sources of reactive energy. This is precisely what sellers who offer an energy saver refer to. Negative reviews on many resources suggest that this is a completely useless device.
Industrial scale
In industries where a huge number of machine tools work, the production of reactive energy is quite large. In this case, of course, it makes sense to look for ways to save electricity.
Through scientific research, it was proved that at the moment of current interruption, when reactive energy comes from the coil, it can be captured using a standard capacitor. Its capacity is selected in accordance with specific technical characteristics.
A capacitor charged with reactive electricity sends it back to the motor, thereby converting it into an active one. So it turns out an industrial energy saver. With your own hands, it can also be created for domestic needs. But the costs of its manufacture are unlikely to pay off in the future. And all because not the scale of the loss of electricity in a private home, which, if used, could significantly affect the amount in the receipt.
World monopoly
Now imagine for a moment that some laboratory was still able to create a device that, in a legal way, significantly affects the amount of electricity used by household appliances.
Such an innovation would not go unnoticed in the scientific world. Its peculiarity is that only a few truly reputable research centers own the right to sell almost all modern devices that can change the quality of human life.
It is noteworthy that some of these discoveries are not made by them, but by small research centers. In this case, the monopolists will not leave the invention unattended and will definitely make the researchers who invented it an offer that cannot be abandoned.
So it turns out that any little-known brand cannot revolutionize the home appliance market. After all, all really worthwhile things are released by eminent manufacturers.
Some trademarks
After purchasing the device, many people leave negative reviews on the forums about it. Energy Saving Econor and Powersaver come under the distribution of dissatisfied customers much more often than others. This is all because online stores sell them the most.
What are these brands? Finding information about them is quite difficult, because before these companies did not exist, but today they offer only this interesting household appliance. But their country of origin is still known: China. This fact itself should seriously alarm consumers. After all, it’s rare when really high-quality goods come to us from the Middle Kingdom.
It turns out that the Powersaver energy saver receives only negative reviews. The positive customer experience found on the sites of online stores can not be considered. They are written by experts to convince people to purchase this product.
Take a look in the box
Each purchased on the Internet energy saver customer reviews causes only negative. They all say that this is fraud and divorce, that the money was wasted, sent to the enrichment fund of regular scammers.
But not everything in the reviews can be called true. He nevertheless performs some action with electric networks. Therefore, it is interesting to see what is inside this miracle device.
Anyone who knows a little about radio components will immediately notice that the device consists of one or two diode bulbs, several diodes and a capacitor or two. There is no more supertechnology or superdetails there.
The entire set of know-how components can be bought at the nearest radio store and soldered this device yourself. There can only remain some questions in what order to connect the parts, from which later an energy saver will be obtained. Its scheme is carefully hidden by sellers, because people who are more or less knowledgeable will see through it how they are trying to deceive them. If a person is well versed in radio engineering, then he will understand everything from the photo of the “insides” of the device.
The scientific rationale for cheating
Obviously, some scientists and electrical engineers could not stay away and watch how some Chinese device breaks their understanding of the world and circumvents some laws of physics.
Therefore, studies have been repeatedly conducted, the purpose of which was to confirm or refute the data claimed by sellers regarding the effectiveness of the device. For this purpose, control samples were bought, and based on their work, measurements of different indicators were made.
According to the results of these studies, an energy saver really reduces current consumption, but its percentage is no more than 3-5, although manufacturers loudly declare 50-60%
The claimed voltage stabilization of the home network is refuted immediately, since no stabilizer can work in parallel with the devices. It should only be connected in series, which is not possible if it is plugged in next to operating devices.
Regarding reactive energy itself, it is worth noting that it is in no way considered a meter, and its amount in the home network is negligible. Therefore, buying an economizer, you will help the energy company more than yourself. After all, she really suffers losses from reactive current.
Slurred wording
Let's turn to sites that advertise the device to save current. This is a separate topic for analysis. And all because they have all the hints that just scream that you are being deceived.
And the most important of them is inarticulate confusing descriptions of the characteristics of the device and the principle of its operation. Each person connected with sales will tell you that the buyer needs to interpret everything as a little child. He cannot be given descriptions with complex terms, and even more so with scientific conclusions.
Experts say that if you try to figure out what the descriptions say, you get so unrealistic things that it is impossible to imagine them in this world. If you translate them into a more understandable language, you get something like "plug the device N into a power outlet, and you will always have a complete lack of gravity in your house." This is impossible, as is what the sellers of economists are talking about.
DIY do-it-yourself device
We already mentioned earlier that you can make an energy saver with your own hands. To do this, you just need to buy a base, solder several parts into it and attach a plug. In the old-fashioned way, you can make an ordinary soap dish, which must be pasted with tape on all sides so that it does not open.
But to find a detailed diagram of this device is almost impossible. Manufacturers hide it, and those who understand the principle of operation of the device, consider below their dignity to make a diagram of a completely useless device.
Therefore, it is better to forget about this idea and think about how you can save more real. For example, replace some light bulbs in the house with less powerful ones, where appropriate: a corridor, a basement, a toilet. This will give about the same percentage of savings, or even more than an expensive Chinese device.
Detailed analysis of all reviews
How do consumers actually value an energy saver? Negative reviews prevail significantly. People are disappointed after a month or two of using the device. They note that the percentage of savings is so insignificant that it could be achieved by unscrewing one light bulb in the apartment.
They also do not notice that the voltage in the network becomes more stable, which is impossible in principle, since there is not a single part in the device circuitry designed to perform this function.
Buyers are disappointed that the high price did not justify itself. All the money was thrown to the wind. And instead of saving, people received significant losses.
We do not take into account positive reviews from sites selling this product, since they are not real there. No electrician or engineer in their right mind will write that such a device is indeed a godsend for the modern user.
Social phenomenon
In times of crisis, people always need to somehow reduce their costs. Utility payments most often fall under the gun. This is what scammers use.
Today, a socio-economic phenomenon has arisen which is an attempt to save money, but at the same time not to break the law, as foreseen, for example, the energy saver Econor. The principle of its operation, according to manufacturers, is precisely to legitimately reduce electricity consumption. In fact, this is the usual swindle and pumping money from the wallets of desperate people.
The danger of constant use of economizers
Finally, it is worth considering another feature that the energy saver owns. Reviews rarely mention this because they are not written by experts.
If the device is constantly connected to the network, then at the moments of minimum load it creates an overvoltage in the network, which can cause a short circuit in the electric motor.
If suddenly it happens that most people believe in his magical abilities and install in their homes, then not only household appliances will deteriorate. This phenomenon is likely to lead to accidents at substations and power outages.
There are no miracles in the world, especially if they are Chinese-made.
