Tesla wants its Powerwall to save the grid and your bank account
Our lust for electricity is insatiable. At night we connect a hydra of wires to our phones, computers, smartwatches and tablets. They sip at the electrons being pumped into our homes, filling their batteries to be ready for another day without being tethered to a wall. Tesla wants your house to be ready. Ready for power outages and heat waves. The company says its Powerwall home battery system can untether your home from the power grid for a few hours, which might not sound like much, but could have huge implications for the way we power our lives.
Tesla CEO Elon Musk introduced the Powerwall at his company’s design studio in Southern California. He said it’s a “whole integrated system that just works and is connected to the internet.” The battery packs are lithium-ion cells with a liquid thermal-control system. Powerwall — which Tesla has been testing with select customers for a year — connects to the internet so it can track power usage and share that information with utilities.
You can reserve a Powerwall right now on Tesla’s site. The device will also be available via distributors, with the 10kWh version offered to installers for $3,500 and the 7kWh model will cost $3,000. This doesn’t include the cost of a DC-to-AC inverter to work with your home. (Solar cell customers will already have that inverter.) Distributors can lease the Powerwall to customers and the device will come with a 10-year guaranteed life with warranty, and will start to ship in late summer.
Tesla says the 10kWh version is more for those on the grid with the ability to run a home once the power goes out. The 7kWh version is geared toward solar cell users wanting to tap into the sun’s power during the evening.
Musk says that Tesla won’t do this alone. It needs partners. To that end, the patents to the Powerwall will be open.

The Powerwall is, at its core, a giant battery like the one found in your smartphone. Like your phone, when it’s not connected to the grid, it still supplies energy. Currently any extra power that’s produced by the utility companies is wasted; power stations ramp up supply as needed. For alternative energy sources, if the wind or sun is providing more power than what the grid requires, all that energy is similarly wasted. The state of California wants public utilities to start storing energy by 2024 to reduce that waste. Tesla’s solution distributes that energy storage to individuals, giving them the opportunity to save some cash and be prepared in case of a power outage.
Tesla made the electric car more than a vehicle for environmentalists because it made it cool. It’s going to be a bit tougher to make the idea of a home battery cool. But if the system manages to save you money and it means power outages can be shrugged off, then Tesla might have another hit.

Mozilla: All new web features should require secure HTTP
A number of internet organizations and even the government want websites to use encryption by default in the future, and from the sound of it, Mozilla shares their view. The non-profit has announced that it plans to limit the capabilities of “the non-secure web” (aka websites that don’t use HTTPS), in order to encourage a more widespread use of encryption. Mozilla has a two-element approach in place, one of which is making all new features of the Firefox browser and its other products available only to secure websites when we reach a certain date. The org will consult its users — just like it did before it ultimately decided it wants to stop supporting unencrypted sites in the long run — not only to pinpoint that date, but also to decide what features are considered “new” by that time.
The other one is to gradually phase out “access to browser features for non-secure websites, especially features that pose risks to users’ security and privacy.” Mozilla knows that will cause many websites to break on its browser, though, so it promises to monitor the situation and attempt to strike a balance. We’ll likely hear more about the plan after the org submits its proposals to the W3C WebAppSec Working Group and when implementation begins. For now, you can read more about Mozilla’s plan on its Security Blog.

HTC posts $11 million profit in Q1 of 2015, expects higher revenue in Q2
HTC has posted their quarterly earnings for Q1 2015, and things look decent for the company. Revenue sat around $1.36 billion, up from $1.08 billion last year, and HTC actually managed to turn a profit instead of a loss like they did in the first quarter of 2014.
They only pulled in $11 million in profit, which isn’t massively successful, but anything is better than their $66 million loss from their previous first quarter.
HTC expects to bring in around $1.5 billion next quarter, so hopefully the HTC One M9 helps the company maintain profitability.

T-Mobile’s Galaxy S6 Edge receiving Android 5.1.1 OTA update
Samsung usually isn’t the quickest when it comes to Android update, but it looks like they’ve worked some magic with T-Mobile, as the Galaxy S6 Edge is now receiving the Android 5.1.1 update over the air. Only the Edge variant on T-Mobile specifically is seeing the update, but that might just mean that the normal S6 (and other carrier models) will join the party soon.
Android 5.1.1 doesn’t do much in terms of features, but it does bring some bug fixes and the like. This update also locks the bootloader on the device, however, so it might be something to keep an eye out for if you like to tinker with your devices.
Anybody else seeing the update?

Daily Roundup: Apple Watch review, Windows 10 and more!
Ready to get caught up on some of today’s top stories? Find out what we thought about the Apple Watch in our review, learn about what’s changed in Windows 10 from Microsoft’s design lead and read why Secret is shutting down. Get all the details about these stories and more in the Daily Roundup.
Apple Watch review: a status symbol for iOS devotees
Mankind’s fascination with watches capable of more than simply telling the time is nothing new. But recently, our collective interest in intelligent timepieces has spiked, and we have more and more powerful wrist-worn computers to choose from than ever – whether made by startups with record-setting Kickstarter campaigns or the biggest names in consumer electronics. Of course, the biggest name of all, Apple, had yet to release one of its own. Well, the Watch has arrived, and its maker has loftier aspirations for it than the smartwatches preceding it.
Windows 10 design lead explains what’s changed (and what hasn’t)
Albert Shum, the design team lead for Microsoft’s OS team, has outlined through some of the decisions made in its new OS. He reiterates that – especially now Windows 10 is out in the open – the work here isn’t yet done, with the blog post focusing on where the team’s received the most.. “feedback”, including the new menu options found on mobile iterations.
Secret’s out: The rise and fall of the anonymous social app
Secret, the app that was practically synonymous with the anonymous-app movement, is shutting down. David Byttow, Secret’s co-founder and CEO, explained in a Medium post yesterday that the reason for the shuttering is that the app no longer represents the vision he had when he started it in January last year. And if the lackluster activity in my Secret feed of late is any indication, I’m guessing the severe decline in users is a reason too.
Jeff Bezos’ first proper test rocket has successfully launched
Elon Musk may be the most famous tech billionaire with an interest in spaceflight, but he’s certainly not the only one. Amazon founder Jeff Bezos also has a company, Blue Origin, which is doing similar research into reusable craft to get us to-and-from the heavens. The normally secretive outfit has just revealed that its first test vehicle, New Shepard, made arguably its most important, partially successful test flight yesterday.
Living with Samsung’s Galaxy Note Edge in an S6 world
I was torn this past winter. I knew the Galaxy S6 was imminent and that there’d likely be a model with a curved screen, but I was dying to see what it was like to live with its bigger precursor, the Galaxy Note Edge. Would I feel a twinge of regret when the shiny new Samsung handset arrived, even if the older phone still had some advantages? There was only one way to find out. I spent a few weeks with the Note Edge to see not just whether I would enjoy that uniquely shaped screen on its own terms, but whether it would still hold its own against the faster, curvier Galaxy S6 Edge.
Watch Tesla’s souped-up Model S beat the world’s fastest sedan
Tesla’s Model S P85D is quick. Or is it fast? Can it be both? Ever since Elon Musk unveiled the company’s speediest car ever, it’s become the fashionable thing to take the P85D to a drag strip and pit it against some old-school gas-powered muscle. Motor Trend did the same, choosing the all-American Dodge Charger Hellcat (the world’s fastest sedan) as the Model S’ opponent. Now, it’s not the first time that these cars have gone head-to-head over a quarter mile, but when they first met, the 707-horsepower Hellcat had such a dismal run that it needed an official rematch with a better driver behind the wheel.
Play classic MS-DOS games without even leaving Twitter
Although they went live at the very start of the year, it was like all of our Christmases had come at once when Archive.org added 2,400 playable MS-DOS games to its website. Retro titles like Maniac Mansion, Oregon Trail and Doom are all available, with the only downside being that you have to visit each specific game’s page to play them. However, the eagle-eyed folk at Wired noticed these have recently started working on Twitter, meaning you can get all of your social networking done while simultaneously saving Sandy Pantz from the evil Dr Fred.

Nexus 7 and Nexus 10 Android 5.1.1 factory images are live
Google has released factory images for the latest version of Android for both (WiFi only) versions of the Nexus 7 and the Nexus 10. The image brings the tablets up to Android 5.1.1, bringing a few bug fixes and performance enhancements, but no new features, unfortunately. The OTA updates for these tablets should start hitting devices relatively soon.
Funnily enough, Google has updated these older tablets to the latest and greatest of Android, but the newly announced Nexus 9 is still on Android 5.0.1. Android updates have always been a pain point, but the Nexus devices were supposed to be immune to the bogged down update process OEMs and carriers subject their devices to. Hopefully Google (or HTC) does something to get the Nexus 9 up to speed.
Hit the link below for the updates. If you need help flashing a factory image, we’ve got a handy guide to get you started.

VLC for Android gets background video playback in version 1.3.2 update

VLC is one of the better media players available on Android, and the app is about to get even better. In the newest update to version 1.3.2, VLC for Android is getting background video playback functionality, a new look for the audio player, and more.
What exactly is background video playback? Just like what you get in YouTube Music Key, videos will keep playing on your device, even if you press the home button or turn the screen off. It’s a very handy feature, and we’re sure many VLC fans will welcome this new addition. To turn on the feature after you update the app, head to Settings>Interface>Play videos in background.

A few other small changes are also present in this update, including a new look for the audio player, a new Album View, improved search, more Lollipop animation effects, a simplified video controller and a new file browser. On the backend, the VLC team has also fixed hardware acceleration for TS files, fixed SD cards browsing, and added better logging and updated codecs.
The new update is now live in the Play Store, so head to the link below to grab the newest version.
Android 5.1.1 factory images arrive for 2012 and 2013 Wi-Fi Nexus 7s and Nexus 10

Google has just published Android 5.1.1 factory images for the 2012 and 2013 Wi-Fi Nexus 7s and Nexus 10, all bearing build number LMY47V. This news comes after the new factory image release for the Nexus Player, which we just saw a little over a week ago.
So what’s new in Android 5.1.1? Well, Google released a ton of bugs with the original build of Android 5.0 Lollipop, and Android 5.1 fixed many of the noticeable ones. We’re not exactly sure what we’re going to see in this new update, but odds are, it’s filled with mostly bug fixes and performance improvements.

Here’s what happens when a lithium-ion battery overheats
Lithium ion batteries are practically ubiquitous; they power everything from laptops and cell phones to cameras and tablets. But before they can start providing the juice for bigger and more demanding applications, research about their failure needs to happen. That’s where the fine folks at University College London come in — they’ve used 3D-and-thermal imaging to track exactly what happens when the power cells overheat, inside and out. As you can see in the GIF above, the results aren’t pretty. After cranking the heat on a pair of the batteries to 250+ degrees Celsius (482 degrees Fahrenheit) and keeping an eye on them with the aforementioned techniques, researchers witnessed one of the batteries blow its top. Prior to that happening, during what’s known as “thermal runaway,” the core collapsed.
What’s that mean?
Well, according to the paper published in Nature, the change in temperature that lead to a destabilizing further change in temperature elevates the risk for internal short circuiting and damaging any nearby components. That only happened in a battery without internal support, though. The cell that wasn’t lacking such a feature was a bit different. After hitting about 1,000 degrees Celsius (1,832 degrees Fahrenheit) the copper internals melted, the heat spread outward and caused thermal runaway. It sounds quite a bit less violent, actually.
This isn’t the sort of thing that would happen under normal operating conditions at all, and UCL’s Dr. Paul Shearing readily admits that. However! He says that this sort of testing provides invaluable knowledge regarding how the lithium-ion cells fail and will hopefully help how safety aspects are designed and considered in the future. I’d imagine that Boeing is paying pretty close attention to these experiments. Call it a hunch.

Xbox One game streaming on Windows 10 is a killer app
With the release of Windows 10, Sony won’t be the only company to offer game streaming from its consoles. Today we finally got our hands on Windows 10’s Xbox One game streaming feature, which lets you bring your entire Xbox gaming experience to any PC running the new OS. And even in its early state, it looks like it will satisfy even the most demanding gamers. Microsoft made a risky bet by demoing the feature with Sunset Overdrive, a fast-paced game where you’d notice the slightest hint of slowdown. And as you can see in the video below, it’s virtually indistinguishable from the native Xbox One experience while running on a Surface Pro 3.
#fivemin-widget-blogsmith-image-30345display:none; .cke_show_borders #fivemin-widget-blogsmith-image-30345, #postcontentcontainer #fivemin-widget-blogsmith-image-30345width:570px;display:block;

Windows 10 streamed Sunset Overdrive at its full resolution, and there weren’t any major issues or delatys. Having spent dozens of hours with the game on my Xbox One, I didn’t notice much of a difference playing it streamed. All of its acrobatic maneuvers and twitch-heavy gunplay felt as responsive as ever. Best of all, you don’t need any crazy hardware to stream games with Windows 10. The demo was running on a fairly typical Intel Core i5 system, and it can run on even slower computers if they have some form of H.264 encoding (because the stream is coming over as a video file). Naturally, your Xbox One gets locked down when you’re streaming something, since it’s still doing the heavy lifting.
So far, Windows 10’s game streaming only works with an Xbox One on your local network. But according to Kevin Unangst, senior director of marketing for Microsoft Studios, the company could eventually implement remote play. That’s something Sony already offers with the PlayStation 4 (and 3, to a lesser extent) over its Vita handheld and some Android devices. But for many people, streaming a game on a PC they already own sounds a lot more useful than having to buy a separate device.
