What Is Wireless Electricity?
Wireless electricity makes it possible to get electric power anywhere you need it without worrying about cords or wiring. It is a new area of technology, but it’s advancing steadily.
Wireless electricity uses radio or microwave transmissions to send power from a transformer or panel to a device. It is also known as wireless power transmission or wireless energy.
You may already be using wireless electricity. If you use cordless chargers in your home, you are familiar with how it works. You can also see it in applications like wireless lighting. Wireless LED lights are convenient, and they can connect to smart sensors in your home. There are limitations, however, to what wireless electricity can do.
How Does It Work?
Wireless electricity requires two coils: a transmitter and a receiver. The transmitter sends an alternating current to the receiver, and this action generates a magnetic field. The electric system uses this magnetic field to create voltage in the receiver coil. You use this voltage to deliver power to a device or charge a battery.
Currently, wireless electricity only works for small devices such as cell phones, electric toothbrushes, and other small, in-home appliances. The technology hasn’t evolved enough to apply to commercial or industrial electrical needs.
Who Invented Wireless Electricity?
Inventor and scientist Nikola Tesla was the first to come up with the idea of wireless power transfers. In 1899, he developed the concept of wireless power transmission using an induction method. Other researchers have attempted to use microwave transmissions, but these are not practical for use around humans. There is still no fully usable method of delivering wireless power on a large scale.
Benefits of Wireless Power
Wireless LED lights have several advantages. You can use them anywhere, and the power source is secure. Because these lights use batteries for power, they will work even during a power failure. For the ultimate in energy savings and independence, choose a system that works with your solar panels to convert sunlight into usable energy.
Wireless lighting is also ideal for outdoor use, where you can install lighting that doesn’t require special cords or protective sheaths. Combine it with motion sensors for even more security. This lighting will work on patios, decks, walkways, and pool areas. Use it to get lighting in sheds, garages, chicken coops, greenhouses, and other outdoor buildings.
Disadvantages of Wireless Power
- Limited applications: Wireless electricity only works when you use it to power small devices at close range. It doesn’t work for large-scale lighting installations or commercial operations.
- Inefficiency: Standard cable charging is much faster than wireless charging. It is too slow for situations that require immediate power availability.
- Not entirely wireless: Most so-called wireless chargers and devices still need a cable that connects to a standard power source. Very few items operate on a purely inductive power source.
What Is the Future of Wireless Power?
Wireless electricity may be the wave of the future. At SESCOS, we’re prepared for all the changes technology brings. In the meantime, we are ready to help you get the power you need to get the most from every day.
