Does Okowatt Work as Advertised and Save Up to 90 on an Electric Bill?

No, nothing can legally save you 90% on your electric bill except by not using 90% of the energy. Here's why:

Fraudulent Claims and Misleading Marketing

No! Anyone with a basic knowledge of physics would immediately spot such a claim as fraudulent. Even without this knowledge, it should be obvious that if such a device worked at all, the technology would have become widespread. Solving the world's energy problems with such a simple device would be a groundbreaking discovery and would have global repercussions. However, it has not gained any traction, indicating that it is indeed a scam.

Total Scam: A Renamed Phenomenon

No, it will not do anything except cost you money. As a matter of fact, I can guarantee it is a total scam that has been relabeled several times in the last ten years. The idea behind these devices usually involves a capacitor contained in a box that plugs into a wall socket, but it is much more skeptical than it seems.

Scientific Inaccuracy and Misconception

Capacitors can sometimes help in balancing the power factor of inductive loads, such as electric motors. However, simply connecting a capacitor to a home appliance does not address this issue. Many efficient appliances already have built-in capacitors for this purpose. The power factor correction needs to be done based on specific calculations for each motor, and these capacitors were often installed during the manufacturing process.

For large inductive loads, such as motors, power factor correction was necessary. This is typically achieved by connecting a specific capacitor of the correct size to the motor based on the motor's inductance. However, these corrections need to be made during the manufacturing process, and field-installed capacitors may not have the desired effect.

What is the Value of an Antique Appliance?

Unless you have an extremely outdated appliance with an electric motor, and the power factor was not corrected when it was built, there is no need to attempt to correct the power factor. In this case, an appliance was likely not designed with a correction, and adding a capacitor may not improve efficiency. In fact, it may have the opposite effect in some cases.

If you really want to improve the efficiency of your antique appliance, you should consult with an electrical engineer to perform a proper review and possible modification.

Therefore, unless you have a unique and specific situation, there is no benefit in using Okowatt or similar devices. Instead, focus on using energy-efficient appliances and practices to save money on your electric bill.
