As a founding member of the Wires Are Evil club, I’ve been waiting impatiently for wide-area wireless charging, where any device on a desk or within a certain area of a room is wirelessly charged. That still seems a way off yet.

A good halfway house would be inductive charging powerful enough to work through the thickness of a desk, so your charging pads sit out of sight on the underside of the desk and your devices charge as soon as you put them down on the right place on the desk. Sadly today’s wireless charging standards are too weedy to work through even the thinnest of desks.

If you want wireless charging today, then, you’re going to have to have a visible wire to a charging pad, and place your device on that. Apple has so far limited wireless charging to the Apple Watch, but if you want it for your iPhone, you can buy a wireless charging case that allows you to use any compatible wireless charging pad. We’ve reviewed a number of these over the years, and I thought it was about time to try one for the iPhone 6 …

iPad-controlled wireless power system charges devices via WiFi up to 20 feet away

While some have been disappointed that Apple hasn’t yet incorporated wireless charging technology into its devices, charging pads are really almost as clunky as wires: you still have wires going to the pads, and you have to put your device in a specific place to charge them. What we really want is true wireless charging, where power is beamed directly to the device through the air.

Which is exactly what Energous has been demonstrating at CES with a system it calls WattUp, reports Engadget.

WattUp […] works using a mix of RF, Bluetooth and a lot of patent-pending technology. The transmitter is where most of the magic happens. It communicates with and locates compatible devices using low-energy Bluetooth. Once they’ve established contact with a device, they send out focused RF signals on the same bands as WiFi that are then absorbed and converted into DC power by a tiny chip embedded in the device. These transmitters can be built into household appliances, TVs, speakers and standalone “energy routers.”

What looks like an oversized Internet router beams power up to 20 feet, so have enough of these – or transmitters embedded into other devices around the home – and your portable devices are powered wherever they are. All that’s needed is for the receiving devices to have the necessary chip.

Energous used an iPad app to demonstrate switching power between devices, but the plan is to build intelligence into the system so that it beams power to devices automatically depending on how much charge they have left. Once your phone has enough power, it switches instead to powering your iPad. As you move around the home, power transmission is handed off to the next source in much the same way as your phone switches between different WiFi networks.

Energous wants to license the technology to manufacturers, and Apple would clearly make a very attractive target.

The clunkiness of charging pads is, I think, why Apple hasn’t yet adopted wireless charging. This, not pads, is the way charging should work, and sooner or later this – or some equivalent tech – is how our iDevices will be charged. I’m very much hoping for ‘sooner.’

Starbucks, in partnership with Duracell, is starting a nationwide rollout of a wireless charging system for smartphones. The system is powered by Duracell’s Powermat technology, which we reviewed last July (starting at $3.50). The program will place 100,000 of the Duracell chargers at specially-marked tables in each Starbucks location. Users would then be able to charge any phone using a compatible wireless charging system.

So far the program has only rolled out in a few stores, but it’s scheduled to reach more markets by next year. There’s not a timetable yet for when the rollout will be complete.

While the program is only available in a few stores right now, a page on the website for the initiative lists locations where the service is currently offered.

New high-resolution photos surfaced over the weekend showing what is expected to be the much thinner iPhone 6 following a report from Venture Beat that corroborates several other claims that the next generation iPhone will feature a larger display than previous models. Included in that report are also claims that Apple will opt for implementing NFC (near field communication), wireless charging, and improved LTE in the next iPhone refresh expected later this year…

Future Macs could lose the cables as Intel demos next-generation wireless charging, docking & displays

If you’re like me and love technology but hate the rats nest of cables it requires, we could be in for some good news. Intel has demonstrated a system that could be incorporated into future computers that allows wireless connectivity for power, displays, and connection to accessories like external drives.

Wireless charging is nothing new, of course, but existing systems are something of a mess. They rely on inductive charging, which is ultra-short range and only suited to low-power devices like smartphones, and there are several competing and incompatible systems in use.

The new system demo’d by Intel uses magnetic resonance charging, which can cope with the power demands of laptops, and works through up to two inches of wood – meaning that the charging plate can be hidden out of sight under a desk. The same charging plate can also charge multiple devices simultaneously, so a single installation under your desk could potentially power your Mac, iPad, iPhone and wireless headset.

For wireless connection to displays and accessories, Intel uses the Wireless Gigabit Alliance system WiGig, which allows speeds of up to 7Gbps over a distance of a few feet – good enough for a completely wireless desk, and rendering my home-brewed iDesk redundant.

The technology will be supported by Skylake, a chip that is currently two generations down the road, and likely to first appear in laptops in 2016. Apple has not yet signed-up, but Asus, Dell, Fujitsu, Lenovo, Logitech, Panasonic and Toshiba are all on board, so it is likely just a matter of time.

As the success stories keep piling up, so do the number of projects filling up crowdfunding websites with, among other things, neat hardware- and software-related products. Some projects, like Pebble, gain thousands of supporters as well as millions of dollars in funding (and end up at Best Buy’s retail stores). Other projects flop and don’t reach their necessary funding amount.

Rather than make you sift through all of these projects, we’re rounding up the best or most notable projects from around the web and delivering them to you in a simple roundup.

If there’s a project that you’ve backed – or even a project that you founded – be sure to leave a link below so it can be considered for the next roundup.

  • The Tastiest Cord Solution: Cord Taco, Cordito, Cordlupa (Kickstarter project) – It’s probably not the best idea to actually eat these cord organizers. However, the unique designs allow you to beautifully wrap up your headphones, USB cords, and Mac charging block in style. Just three days into it, this campaign is half way to meeting its $15,000 goal.

Apple patents unlikely SmartCover wireless charging system

However unlikely—the United States Patent and Trademark office today published an Apple patent application that details a system of inductively charging an iPad through the Smart Cover. The idea is that rather than plugging in the iPad, the Smart Cover would include an inductive power transmitter that would allow it to pair with an inductive power transceiver embedded into the iPad. The result is the Smart Cover would become a wireless charging station, connecting to an external power source, and allowing you to power your iPad in various positions. Apple also explained that it could use “ambient power gathering devices, such as solar cells, can be used to gather ambient power (such as sunlight) to be stored internally in the flap for later inductive transfer.”

A method for wireless powering a tablet device, comprising: determining if a protective cover is in a closed configuration with respect to the tablet device; enabling a wireless power receiver circuit in the tablet device when it is determined that the protective cover is in the closed configuration with respect to the tablet device; and wirelessly receiving power from a wireless power transmitter associated with the protective cover.

Apple described the advanced Smart Cover as including multiple power transmitters to allow the iPad to charge even when using the case, for example, as a stand to prop up the device. Alternatively, the cover could continue charging the device when in the closed position or when an iPad is placed on top:
