Waterless Washing Machine Levitates Laundry and Cleans It With Dry Ice

Waterless Washing Machine The spherical drum floats through magnetic levitation. Elie Ahovi
It makes my day when new technology promises to make life’s most tedious tasks more interesting. Take laundry, for example. I would loathe it so much less if I had a friendly robot to help me fold my socks. Or perhaps if I had this waterless washing machine, which would levitate my clothes and scrub them clean with dry ice in a matter of minutes.
The Orbit uses a battery-filled ring to levitate a supercooled superconductive metal laundry basket. The basket is coated in two layers of shatterproof glass and chilled using liquid nitrogen. The batteries inside the ring produce a magnetic field, and the basket levitates inside this field as its electrical resistivity drops.
The laundry orb, which is opened and controlled using a ceramic-based touchscreen interface, blasts sublimated dry ice at supersonic speeds toward your clothes. The carbon dioxide interacts with the organic materials in your laundry and breaks them down. Then the dirt and grime is filtered out through a tube that you can rinse, and the CO2 is removed and re-frozen (though it’s not clear how, because this would require lots of energy). Voila, clean and dry clothes.
At this point it’s just a concept by designer Elie Ahovi, but it’s not hard to imagine these types of cleanerballs in apartments of the future. Anything that will cut down on time spent doing laundry.

Wind-Powered Car Travels At Twice the Speed of the Wind

Which sounds weird but actually makes perfect sense

Blackbird Rick Cavallaro via Wired
A couple of years back, Rick Cavallaro and his wind-powered car--Blackbird--silenced an online debate about whether its possible for a wind-powered vehicle to move downwind faster than the speed of the wind itself by going out and outrunning the wind. Now, Cavallaro and company have reconfigured their car to travel upwind and proved that it’s possible to travel upwind at more than twice the speed of the headwind, setting what has to be a record for upwind terrestrial sailing.
That’s not quite as big of a bombshell as the downwind run back in 2010, in which a lingering and sometimes vitriolic physics debate was quashed when Cavallaro recorded downwind speeds at 2.86 times the speed of the wind. But this time he’s managed to log 2.01 times the speed of the wind going upwind--still a significant feat.
And also a counter-intuitive feat, though when you really think about it the physics are the same as a sailboat tacking upwind. The turbine blades act as sails, turning to create power. Rather than having a keel to counteract the push of the headwind and maintain the proper upwind direction, Blackbird’s transmission and wheels have been designed to do that job.

Nokia Lumia 900 Review: Bigger Is Not Always Better

The sequel to the best Windows Phone we've ever used is...not the best Windows Phone we've ever used

Lumia 900 and iPhone The Lumia is the bigger one. Dan Nosowitz
If you want to buy a phone right now, and you're shopping based on quality rather than price, you have two choices in terms of size. You can get the iPhone, with its 3.5-inch screen, or you can choose from a handful of top-tier Android and Windows phones, all of which will have, at the bare minimum, a four-inch screen. Most of them will be bigger--4.3 inches is much more common right now, and an increasing number are even larger, including the Samsung Galaxy Nexus(4.65 in), HTC Titan (4.7 in), and the Samsung Galaxy Note (which, at 5.3 inches, is more lunchtray than phone).
The Nokia Lumia 900 is essentially a 4.3-inch version of the Lumia 800, a phone I absolutely loved in its 3.7-inch iteration (a Europe-only model). So reviewing the Lumia 900 presents an interesting question: with most other specs remaining constant, how does the experience of using a phone change when it grows to the size most phone manufacturers insist we really want?

WHAT'S NEW

The Lumia 900 is Nokia's first "flagship" Windows Phone that's available in North America (the Lumia 710, a cheapie, has been available on T-Mobile for a little while already). It's the sequel to the much-admired Lumia 800 and its changes are mostly in size (of various sorts). It's got a 4.3-inch screen, compared to the Lumia 800's 3.7-inch screen; it has 4G LTE (on AT&T), compared to the Lumia 800's 3G; it has a bigger battery and a front-facing camera.

WHAT'S GOOD

This is mostly a good phone. Windows Phone is a great operating system; it's still maturing, but it's very usable, and it's an interesting and distinctly different approach to a smartphone than iOS or Android. (More on that here.) The physical design is pretty good; it's inoffensive, at worst, and is weighty enough to feel sturdy rather than cheap and plasticky, as many Windows Phones do (especially those made by Samsung). It's also nicely thin, only a millimeter or two thicker than the iPhone. The screen, though not thrilling in its resolution, has great deep blacks, which is important when using an OS with a predominantly black interface by default.
AT&T'S 4G LTE continues to be great. This is the first phone using AT&T's LTE I've personally used, and it feels just as screamingly fast as Verizon's. It's startling how quickly things load--LTE is as fast or faster than many people's home internet connections, so apps download instantly, web pages load instantly, music and podcasts sync instantly. I was impressed with AT&T's coverage too--I used the Lumia 900 all over New York City and it never dropped out on me. And the giant 1830mAh battery will get you through a full day with normal use, which is not always the case with the current crop of LTE-capable phones.

WHAT'S BAD

Bigger is not better. Gadget makers will tell you I'm wrong--they'll point to sales numbers, saying that people have embraced big phones by the millions. But you could just as easily point to the iPhone, the most successful phone line in the country by a long shot, and say that it proves that people love smaller phones. Or you could remember that if you want a good Android or Windows phone, you are basically forced to buy a giant one. There are no longer any top-tier 3.7-inch phones. There are a rapidly decreasing number of 4-inch phones (the Motorola Droid 4, an above-average but not particularly special phone, is the only high-end 4-incher released in the past six months). If you're shopping Android or Windows, your choices are limited to big or bigger. And that's not necessarily for the better.
Most gadgets need to be of a particular size to fulfill their particular roles. A phone has to fit in your pocket or purse. An ebook reader has to display a page of text. A tablet has to provide a full web experience. You can't just stretch it out, like it's a Gumby made of silicon and glass and metal and plastic, and say it's a better device because of it. And that's exactly what the Lumia 900 is. The phone is big--not as big as a Galaxy Note, but big. It's actually wider and thicker than the Samsung Galaxy Nexus, a phone with a substantially bigger screen.

I have small hands (we all have our hurdles in life), and for me, any phone with a screen bigger than four inches is more difficult to use than it's worth. In regular use, I find myself constantly readjusting my grip--I can't hold the phone and reach all parts of the screen with my thumb. Beyond the overall size increase, I don't think the bigger screen has any real benefits in this case. The Windows Phone keyboard is excellent; I never found it awkward to type on the smaller Lumia 800, so unless you have the sausage fingers of Billy Joel (YouTube it, the dude has ten kielbasas attached to his palms), I can't imagine this being a striking improvement. The screen is also mathematically worse than the Lumia 800's. It's the same exact screen--a PenTile AMOLED screen with 800 x 480 resolution and Nokia's ClearBlack tech, which, if you don't understand that, congratulations for not having so much nonsense rattling around in your head. What matters is that it's the same number of pixels stretched across a larger canvas—the opposite of Apple's approach with its Retina Display—which means a visible downgrade in image quality.
So on the Lumia 900, the picture is worse. It creates a bigger bulge in my pocket. What's the point?
All the buttons are on the right edge of the phone, even the power/hold button, which is often found on the top edge. That's essential, because it's not really possible for anyone besides Hakeem Olajuwon to reach the top edge of the phone while holding it with one hand. But with it placed on the side, I found myself accidentally hitting the hold switch often, since it falls directly under your right thumb.
The design is also somehow not quite as enthralling as the sleek Lumia 800, even though it's nearly identical. It's the little things, which add up to a different impression when you're dealing with a very simple design presentation. Example: the 800's screen was curved, with the screen seeming to melt off into the sides of the phone like an infinity pool. The 900 has a typical flat screen, with a more definitive bezel between the screen and the sides of the phone, and a weird raise ridge around the edges. It's a very minimalist design, which worked for the 800, because it had nice little touches and felt compact and sharp. The Lumia 900 isn't bad-looking, and it's certainly well-crafted, but it's also not that interesting.
The camera remains not very good. I was surprised at this with the Lumia 800, and I'm still surprised--the Nokia N8, probably the worst phone I've ever reviewed, had a stellar camera, and Nokia is well-known for their phone cameras. The Lumia 900's is average at best--I love that it has a dedicated shutter button, and shutter speed is pretty good, but I wasn't impressed with image quality. The Lumia often came up with very dark shots, and color reproduction was sometimes off. And in lower-light situations, photos were extremely noisy.

Nokia Lumia 900 vs. iPhone 4S: Near and Far: A couple more comparisons: the Lumia 900 took the two photos on the left, while the iPhone 4S took the two on the right. You can see that the Lumia works okay in full sunlight, but still has troubles with shadows and differences in light (look at the slanted shadow on the building to the right of the Empire State Building, or how the daffodils blend into the brighter sidewalk in the upper left corner). Click here to get a bigger view.  Dan Nosowitz
The hardware handles the Windows Phone operating system pretty nicely; it's responsive and fast, for the most part. The way it scrolls still feels not quite as organic as iOS--there's a little lag, and sometime the "flick" motion results not in a super-fast scroll, like you wanted, but a slow trudge downwards through a list. Otherwise the software has the same ups and downs (and it's mostly ups, to be clear) as any other Windows Phone, plus a few Nokia-specific apps (Nokia Drive, a free turn-by-turn GPS app; yet another mapping app, Nokia Maps; and a little Nokia-curated section of the App Marketplace).

THE PRICE

It's available on AT&T for $100 with a two-year contract. That's half the price of other 16GB phones like the iPhone, and probably a good way for Microsoft and Nokia to worm their way back into the public consciousness. It's a good deal, though given the fact that you're signing a two-year contract that'll cost you several thousand dollars in voice and data plans, it doesn't really make sense to care much about an extra $100 up front.

THE VERDICT

The Lumia 900 is a pretty good phone--I still think the iPhone is a smarter buy on AT&T, due to its gigantic and thriving App Store, sleeker hardware, and more polished software, but the Lumia 900 is very nice. And yet I don't think it's as good a phone as the Lumia 800 (though the LTE speeds are delightful). It's a weird feeling to be disappointed while still recommending a product, but that's how it goes--the 900 doesn't live up to my expectations, but it's still the best Windows Phone in America. Still, it feels a little dull, where the Lumia 800 felt fresh and new and stylish. But most of all, I'm turned off by the size. Dear phone manufacturers: I know it's an easy sell to say that your phone is bigger and therefore better--but for some of us, it's simply not the case.

Smartphones Will Become the Only Device Hardcore Gamers Need

The Pocket Console Alison Seiffer
When Sony, Microsoft or Nintendo introduces a new videogame console, its obsolescence within six years is more or less assumed. Nintendo is likely to release the new Wii U later this year, and other console makers are rumored to be working on next-generation systems. But as early adopters line up to experience whatever new high-def graphics those systems may offer, the next-next generation of console is already gaining momentum. The device is the smartphone, and within a decade it could be powerful enough to replace conventional game systems for good.
Mobile gaming began in 1979 when the Milton Bradley Company introduced the Microvision cartridge-based system. Since then, Nintendo, Sega and Sony have released many more portable systems, from the Game Boy to the recent quad-core PlayStation Vita. Although many of these devices were a great success among gamers (to date, Nintendo has sold more than 50 million of its DS systems), they never gained a substantial following among the general public.
Then in 2008, Apple launched the App Store, providing a simple and accessible distribution platform for games. One year later, the company Rovio released Angry Birds. Within a year, 50 million people had downloaded the app, spurring developers to create more engaging portable games. Now 64 percent of smartphone owners download games, and 37 percent of iPhoneowners say they play daily.
Smartphone games are still a far cry from the richly textured and fast-moving console experiences that hard-core gamers love, but that could change rapidly. Today’s fastest phones already have quad-core 1.5-gigahertz processors—a fraction of the horsepower of a PlayStation 3—and others can send full 1080p high-def to a TV over HDMI. Mobile processors are hitting the steep part of the Moore’s Law curve, where power increases sharply with every year. One day soon, a five-ounce phone’s specs could rival those of the current best laptop.
Such a sharp increase in mobile power will most certainly provoke further attrition in the gaming ranks. Android and iOS already claim 58 percent of the portable-gaming market, and console game sales are on the decline. But for smartphones to gain dominance, users will need better ways to access console-level games. Either cloud-based delivery services will license a broader range of titles, or flash memory will improve to the point that a phone can store many console games (at present, one game could consume half a typical phone’s 16 gigabytes of memory).
Once the barriers to access fall, though, the phone will become a dual-purpose game hub. Mobile gamers will probably continue to rely on app-based games—who would want to playSkyrim on a four-inch screen, anyway?—but home gamers will have a dramatically different experience. Rather than firing up an Xbox or PlayStation, they will pair their phones with their TVs and wireless controllers. Discs will become obsolete, shelf space in the home entertainment system will open up, and users will carry a self-contained game system wherever they go.

How Invisible Nano-Coatings Can Make Any Phone Waterproof

Phone Sploosh Claire Benoist
More cellphones meet their demise from exposure to moisture than from any other cause--so we've all got a vested interest in waterproof phones. In the past, a user who wanted to protect his phone had to buy a watertight case, and thus double the size of the device. Last year, the company P2i introduced a less clunky approach: coating devices in invisible, water-repelling nano-polymers. But that solution only guarded against splashes, not submersion. Two companies, HzO in Utah and Liquipel in California, have now refined the technique to make devices resistant to both spills and dunks.
Both companies use similar application processes to bond the nano-polymers to phones. They place the devices, or their internal components, inside a sealed chamber, vacuum the air out, and inject a carbon-based gas. The vapor settles on the object and solidifies in a transparent layer that’s one thousandth the thickness of a human hair. When water hits a protected surface, it beads up and rolls off. The main difference between the companies is what they protect; HzO treats only internal parts, such as processors and sensors, whereas Liquipel coats both the interior and the exterior. In HzO’s tests, a treated iPhone survived underwater for more than four hours.

TESTING

For $59, Liquipel will retro-waterproof any of a dozen cellphone models, including iPhones and Samsung Galaxy handsets. Because the nanoparticles are so small, they can penetrate seams to reach and coat the internal parts of an already-assembled device.
The test: We sent the people at Liquipel a working iPhone 3GS to treat. When the device was returned a few days later, looking indistinguishable from before, we powered it up and held it under a running faucet for about five minutes.
The results: The phone operated normally while under the faucet. Afterward, it took a couple of seconds to react to touch—probably because of droplets that hadn’t yet beaded up and rolled away—but then worked as if nothing had happened.

There Will Be Enough Giant Phones Sold in 2015 to Pave Monaco


Samsung Galaxy Note at Window Dan Nosowitz
A firm of analysts has just issued a report predicting that shipments of giant smartphones like the Samsung Galaxy Note, will reach a completely bonkers 208 million in 2015, which, if our math is correct, is only a few years away. That's actually not that crazy of a guess; they are defining "phablet" (an awful, influenzal word portmanteaued from "phone tablet") as any phone with a screen size between 4.6 and 5.5 inches. These are certainly gaining in popularity, what with Samsung, the world's biggest phonemaker, basically releasing nothing else. But let's just think about the physicality of that much phone for a second.
The Samsung Galaxy Nexus, a 4.65-inch phone measured diagonally, has a 14.25775-square-inch face. That's about as small as you can get and still be considered a "phablet," so we'll go with that as a conservative baseline. Thanks to the magic of Wolfram Alpha, we know that 208 million of those would have a square footage of 2.059 x 107. That means:
You could pave 98 percent of Monaco...

You'll Soon Be Able to Buy a Firefox Phone

Firefox OS Mozilla
Mozilla has been making some small moves into mobile with the Firefox browser for Android, but today the company announced much bigger plans: Firefox OS, previously known as "Boot to Gecko," is an entirely new operating system for smartphones. The OS will be based on Linux, but all apps will be entirely browser-based, built on HTML5, like Google's Chrome OS.
It's a surprisingly well-planned announcement; Mozilla is already several steps into the process, having already lined up hardware and network partners. The hardware will be made by Chinese company TCL, which here in the States makes things under the RCA brand, and ZTE, which makes mostly low-end phones, and will include Snapdragon processors from Qualcomm. On the network side, they're working with Sprint, Deutsche Telekom, Telefónica and more. Given the choice of hardware partners, I'd expect the Firefox phones to be aimed more at the low-end market, perhaps especially in developing nations.
It's ridiculously difficult to gain a foothold in the smartphone OS world--just ask Microsoft--but a browser-based solution could be made cheaply and easily. We'll see how well the Firefox OS works; Mozilla says the first devices to use the OS will appear in Brazil next year. You can read the full press release here.
