The clean energy boffins in their labs are always upping the theoretical limit on how much power you can get out of sunshine, but us plebes actually installing solar cells are stuck with years-old tech that’s not half as good as what they’re seeing. This new design from Insolight could be the one that changes all that.
Insolight is a spinoff from the École Polytechnique Fédérale de Lausanne, where they’ve been working on this new approach for a few years — and it’s almost ready to hit your roof.
Usually solar cells collect sunlight on their entire surface, converting it to electricity at perhaps 15-19 percent efficiency — meaning about 85 percent of the energy is lost in the process. There are more efficient cells out there, but they’re generally expensive and special-purpose, or use some exotic material.
One place people tend to spare no expense, however, is in space. Solar cells on many satellites are more efficient but, predictably, not cheap. But that’s not a problem if you only use just a tiny amount of them and concentrate the sunlight on those; that’s the Insolight insight.
Small but very high-efficiency cells are laid down on a grid, and above that is placed a honeycomb-like lens array that takes light and bends it into a narrow beam concentrated only on the tiny cells. As the sun moves, the cell layer moves ever so slightly, keeping the beams on target. They’ve achieved as high as 37 percent efficiency in tests, and 30 percent in consumer-oriented designs. That means half again or twice the power from the same area as ordinary panels.
Certainly this adds a layer or two of complexity to the current mass-manufactured arrays that are “good enough” but far from state of the art. But the resulting panels aren’t much different in size or shape, and don’t require special placement or hardware, such as a concentrator or special platform. And a recently completed pilot test on an EPFL roof was passed with flying colors.
“Our panels were hooked up to the grid and monitored continually. They kept working without a hitch through heat waves, storms and winter weather,” said Mathiu Ackermann, the company’s CTO, in an EPFL news release. “This hybrid approach is particularly effective when it’s cloudy and the sunlight is less concentrated, since it can keep generating power even under diffuse light rays.”
The company is now in talks with solar panel manufacturers, whom they are no doubt trying to convince that it’s not that hard to integrate this tech with their existing manufacturing lines — “a few additional steps during the assembly stage,” said Ackermann. Expect Insolight panels to hit the market in 2022 — yeah, it’s still a ways off, but maybe by then we’ll all have electric cars too and this will seem like an even better deal.
Amazon sets a date for its big 2021 Echo and Ring devices event
Amazon has set the date for its next big devices and services event, and if previous years are anything to go by we can expect new Echo and Ring hardware along with potentially a few surprises. The event will kick off at 9am PT (12pm ET) on Tuesday, September 28, and as with last year’s it’ll be online-only.
Last year Amazon didn’t hold back on new smart home hardware. Along with the new Echo Show 10, which could rotate under its own power to face the person interacting with it, Amazon also had a new, spherical Echo smart speaker.
The smaller Echo Dot – and its Echo Dot with Clock sibling – offered a lower price point, and the new Echo Dot Kids Edition dressed that up in more playful designs. As for Ring, we saw the Ring Car Alarm debut, plus the promise of end-to-end video encryption. Amazon also announced a collaboration with Tesla, with the Ring Car Connect for the automaker’s EVs.
Elsewhere, the Eero Pro 6 and Eero 6 added WiFi 6 to the familiar mesh networking, while the Fire TV Stick and Fire TV Stick Lite kicked off pricing at under $30. Amazon also introduced Luna, its cloud gaming service, complete with a dedicated wireless controller.
Just as much a showcase for hardware, though, Amazon’s events have become demonstrations for its software changes. Alexa typically plays a key part in that – last year we saw group calling support, Netflix on Echo Show, and interactive teaching tools – but it’s also an opportunity to see what developer tools and improvements have been introduced.
Finally, it’s a chance for Amazon to surprise. Last year, that meant the Ring Always Home Cam – a flying camera drone that promised automated patrols of your house – though the gadget is still yet to actually launch commercially.
For 2021, it’s likely we’ll see refreshes of Amazon’s core Echo range. After all, with the holidays approaching, that’s a key opportunity for Amazon to put more smart speakers in users’ homes – and double-down on their commitment to Alexa as a platform, rather than the Google Assistant or Apple’s Siri. The new Amazon-branded Fire TV range could also be expanded.
We’ll probably also hear more about the controversial Amazon Sidewalk, the shared neighborhood network that Amazon opted to enable by default earlier in the year.
On the “weird tech” side, that could well be the rumored wall-mounted Echo touchscreen. Billed as being an in-wall smart home hub, it would help position Alexa as a key way of interacting with the connected home and IoT, if the rumors are to be believed.
After iPhone 13: The new tech coming in 2022, 2023, and 2024
Over the next few years, the iPhone will see some significant changes. This year’s iPhone 13 didn’t exactly make major waves when it came to upgrades VS last year’s model lineup. According to high-level Apple product predictions released this week, the changes will come in the years 2022, 2023, and 2024 in the form of punch hole front-facing cameras, under-display Touch ID, and foldable smartphones from Apple.
Notes from Apple analyst Ming-Chi Kuo relayed by 9to5Mac suggested that the iPhone line released in the year 2022 would include two higher-end devices with a punch-hole display. Kuo also suggested that these devices would include a new 48MP wide camera, and would be joined by a new and “more affordable” 6.7-inch iPhone.
Kuo also noted the addition of an under-display fingerprint reader for the year 2023. This technology began to appear in Android devices over the last few years, but hasn’t yet matured to the point at which Apple has been comfortable releasing it on a release-level iPhone. The iPhone under-display Touch ID system is predicted to be a part of the iPhone 15 (or whatever it’ll be called) released in the year 2023 – or later.
The most massive change to the iPhone line comes in the prediction of a foldable device. Ming-Chi Kuo suggested that the “foldable iPhone” won’t be released until the year 2024. It is not yet known whether this foldable iPhone will be released at the same time as the traditional iPhone, what it’s price will be, or if it’ll actually truly ever be released at all!
ALSO NOTE: There’ll likely be a new iPhone SE coming in the year 2022 with expanded mobile data radio coverage. This means 5G support for said iPhone SE, likely appearing in the first half of the year 2022.
If you’re currently preparing to purchase an iPhone and want to wait for the newest possible device – you’re in luck, since the iPhone 13 will be available in stores on September 24, 2021. The release date is the same for iPhone 13, iPhone 13 Mini, iPhone 13 Pro, and iPhone 13 Pro Max, all coming on September 24th, 2021. Take a peek at comparisons between the iPhone 13 models and iPhone 12 and see what you make of them. Then stick around as we prepare to release our review of the iPhone 13 and beyond!
IKEA Sjomake makes DIY hidden wireless charging a $40 upgrade
IKEA is making it easy to hide wireless charging in your nightstand, desk, or coffee table, with the new Sjömäke wireless pad keeping its Qi out of sight. Unlike IKEA’s earlier charging pads, which slot into circular cut-outs in the tabletop, this new high-power pad is intended to hide underneath yet still allow for wireless charging through the surface.
In fact, IKEA claims, it should work just fine through tables and other worktops that are 3/8″ to 7/8″ thick, just as long as they’re not metal. The Swedish retailer includes double-sided tape for mounting it underneath, though there’s also support for screws or other fixings if you prefer.
Plug in the six foot long power cable, meanwhile, and then you have a discreetly hidden Qi charging pad. IKEA includes some stickers that you can optionally use on the top of the table or nightstand, so that you know whereabouts to position your phone or other device for best charging results. Or, you can leave them off altogether, and have the whole thing seem a little more magical.
The pad is a fairly uninspiring design, given it’s intended to be hidden from sight. It’s 1-inches thick, 7-inches long, and 3-inches wide. An indicator LED on the side shows whether or not it’s actively charging a device, though of course there’s a fair chance that you won’t be able to see that in day to day use.
Indeed, IKEA says that you really shouldn’t use the pad with a phone or other device without anything in-between. According to the user manual, there should be at least around 8mm between the two, presumably because IKEA has tuned the charging coils to take into account some sort of gap.
As for the charging rate, expect around 5W. Less, certainly, than you’d get from some of the other Qi pads on the market right now, but certainly sufficient if you’re leaving your phone to one side as you sleep or work.
Currently, the Sjömäke is listed at $39.99 on IKEA’s site, though it’s not yet available to order. The retailer confirmed to The Verge that it will be going on sale in October, both in the US and in other international stores, both at its physical locations and online.
This isn’t, of course, IKEA’s first flirtation with wireless charging. Back in 2018, the company ran a high-profile welcome campaign for the iPhone 8, highlighting how Apple’s addition of Qi support meant that the smartphone would now work with the Swedish company’s chargers that were build into tables, lamps, and more.
