Electricity is amazing. You spin a coil of wire through a magnetic field and next thing you know everyone with access to an outlet has clean, quiet, instantaneous, and virtually unlimited power at their fingertips, whenever they need it. Wild. It does have a couple of drawbacks, though.

Wireless charging is on the verge of busting out. Watch Don`T Say A Word Download. In my next post, I'll focus in on wireless electricity for transportation, where it has the potential to have.

One, mobile electronic devices — lawnmowers, phones, electric vehicles (EVs), drones, what have you — have big batteries and limited range. You have to remember to plug them in periodically, or replace the batteries, or you're screwed. Plugging things in may not seem like that much of a hassle, but it shapes the way we live with electronic devices in subtle and pervasive ways.(Shutterstock)Imagine, then: What if everything electronic could be charging all the time, without wires? What if wireless chargers were built into tables, counters, desks, roads, and parking spots, continually recharging the electronic devices around them?

What if electric power became ambient? That scenario is not science fiction, at least not entirely. There are wireless charging technologies on the market, more coming in the next year or two, and more still proving their viability in laboratories. Freedom from wires is no longer a pipe dream.

But there's a long road between the lab and commercial viability — and a longer road still to ubiquity. A wireless future is visible over the horizon, but it is by no means inevitable. Today I'll explorehow wireless electricity works, the various technologies involved, and some of the companies trying to commercialize those technologies. In my next post, I'll focus in onwireless electricity for transportation, where it has the potential to have greatest impact. All right, let's dive in! Wireless electricity is not new, but it's about to bust out of obscurity. Wireless power transmission (WPT) — as improbable and borderline magical as it seems — has been around for a long time.

Way back in 1. 83. Michael Faraday discovered electromagnetic induction: Put crudely, a current running through a wire creates a magnetic field that induces current in nearby wires. In the 1. 89. 0s, badass Serbian inventor Nikola Tesla built an experimental laboratory in Colorado Springs where he demonstrated the effect at a distance, with his .

It was pretty cool. Nikola Tesla's magnifying transmitter at work, around 1. More here.)Wireless charging has been used in limited applications ever since, but it's generally been too finicky, expensive, and inefficient to catch on for wide commercial use.

That is changing, though. Three big sources of demand are pulling wireless charging forward: the spread of consumer and wearable electronic devices, the electrification of vehicles, and the automation of industrial processes. To get a sense of the range of stuff going on, it helps to understand how wireless charging works. Wireless power works like wireless information, only more intense. At the most basic level, WPT involves a transmitter of some kind and a receiver of some kind.

The transmitter converts electrical energy into a time- varying electromagnetic field; the receiver converts it back into electricity. Sharp- eyed readers will note that this is roughly the same way wireless information transfer works. TV broadcasting, radio, wifi — they all use the same electromagnetic fields and waves.

In all those cases, some energy is transmitted as well, but only a tiny amount, enough to preserve the integrity of the signal. The signal is the point. With WPT, the amount of energy that reaches the receiver is the point. That's why its range is much more limited than wifi or radio; it's difficult to transmit energy very far without it diffusing. So let's take a tour of WPT technologies — the ones already available commercially and the ones struggling to make the leap from lab to market. Near- field power transmission. WPT divides into two big buckets, loosely classified according to range of transmission: near- field (non- radiative) and far- field (radiative).

Near- field means within roughly one wavelength of the transmitter, a distance that will vary based on the size and structure of the transmitter. Transmitters small enough to fit in cellphone charging pads usually have a range of around a centimeter, which is why phones have to sit directly on them. Larger transmitters, as in EV chargers, can make it several inches.(Shutterstock)Within one wavelength, magnetic and electric fields remain separate. Consequently, there are two forms of near- field transmission, inductive coupling (which uses magnetic fields) and capacitive coupling (which uses electrical fields).

Inductive coupling. With inductive coupling, power is transferred between two coils of wire via a magnetic field. Almost all currently available wireless charging products use inductive coupling.

That's what your electronic toothbrush uses. And it's what all the new wireless cellphone charging pads use. For most current phones, you also have to buy some kind of case to serve as a receiver, but in many new phones (e. Samsung Galaxy S7) the receiver is being built in.

The process of getting wireless charging into phones has been slowed by confusion over standards. There are currently two separate standards governing inductive coupling, the Wireless Power Consortium's ?

Standards talk is boring. More here if you're interested. Inductive coupling for phone charging has its critics. It's still slower than charging by cable, and less efficient, and it generates more heat, which reduces battery life. Worst of all, you have to position your phone precisely on a pad (which has to be plugged in!) and leave it there, which a little more convenient than plugging it in directly, but only a little. Nonetheless, products are beginning to catch on.

Ikea already has a line of furniture with chargers built in. Inductive coupling is also behind the only wireless electric vehicle (EV) charging system currently available on the consumer market: Plugless Power. Virginia- based Evatran began developing the product in 2. Google in 2. 01. 1, and began selling to consumers in 2. I'll have more to say about Plugless Power in my next post. Suffice to say, even given the limitations of inductive coupling, wireless charging has the potential to change transportation systems in all sorts of interesting ways.

Capacitive coupling. The other kind of near- field transmission iscapacitive coupling, whereby power is transferred via electric field between two metal electrodes, which together form a capacitor. This has had some scattered uses in low- power applications, but it's fairly limited, in part because electric fields, unlike magnetic fields, interact with objects, including such objects as the human body.

And electrodes need a pretty high voltage to transmit power, so there are safety issues. Resonant coupling. Here's where things get interesting.

Plain old inductive coupling involves omnidirectional transmission. The field radiates out from the transmitter in all directions; unless the receiver coil is very, very close, it doesn't pick up much energy. That's why cellphones have to sit so precisely on those charging pads. Then there's resonant inductive coupling, or . Thus tuned, they become .

It was demonstrated by a team at MIT in 2. The head of that team, Marin Solja. Here's a 2. 00. 9 TED talk about it: Wi. Tricity calls its product . It makes a development kit meant to enable other companies to create wireless power products. As far as I know, none of those products are on the market yet, but it sounds like lots are on the way, as soon as this year.

Other companies are getting in on the action too. Check out Intel's . One — developed by the old Alliance for Wireless Power (A4. WP) before it merged into the Air. Fuel Alliance — is called .

It works over longer distances than inductive coupling, and at a wider array of orientations, eliminating the need for precise device placement. It can charge multiple devices at once.
