Wireless Power Transferred Through Thick Concrete Could Mean Electric Cars That Charge While You Drive

One of the biggest issues preventing the electric car from taking over the roads is their incredibly limited battery life. But researchers at the Toyohashi University of Technology in Japan have demonstrated a new system that could let electric cars constantly recharge while they're being driven.

Their research has resulted in a system that's able to transfer somewhere in the neighborhood of 50 to 60 watts of electricity through almost 4 inches of concrete, allowing the power source to be safely buried beneath a roadway. And specially adapted tires which are wired into a vehicle's power system could then harness that electricity and use it to top off the battery.

At the moment the system exists as a low-power proof-of-concept of the technology, and would require about 100 times more power to actually charge an electric car's battery while it was running. But they claim the components needed to ramp it up are cheaply available, and the system could even work with concrete layers almost eight inches thick if needed. More here.

Ice Cream Sandwich Consumed by One in Ten Android Devices

The latest Dashboard numbers for Google's Android operating system have been released. The verdict? One in ten devices is leveraging Ice Cream Sandwich as their mobile OS of choice. 

The numbers, which are current as of July, put Gingerbread (Android 2.3) in first place with a 64-percent install base; followed by Froyo (Android 2.2) with 17.3-percent and ICS with 10.6-percent. Jelly Bean (Android 4.1), announced just last week at Google's IO Developer Conference, was not included in this instance of the report (as it is not officially available yet). More here.

Are You Comfortable With Airlines Researching You on Google?

According to the London Evening Standard, British Airways is beginning a program in which employees google the faces of passengers for upcoming flights so that they may immediately greet them upon entry to the airport gate/airplane. Some feel this is an invasion of privacy. But is it really that big of a deal? More here.

How to Make Your iPhone Charge Wirelessly


Wirelessly charging your iPhone would be pretty great, but not with the dumb cases that inductive charging requires. That's why this mod from Tanveer is so great. A regular iPhone that charges when you set it down. The future!

Here's what you'll need, according to Tanveer, in addition to some serious soldering skills:
patience
a steady hand
soldering tools
a spare charger port assembly
very thing gauge wire
a spare back cover
a wireless charger circuit (probably homemade from parts)
It's a pretty involved hack that will obviously void your warranty. You not only have to solder tiny wire to tiny pins, but you've got to add 1mm of give to an iPhone back panel. It takes some serious work, but for a 1mm-thicker iPhone that you don't have to plug in to charge? Kind of worth it. More here.

Samsung Announces 75-inch ES9000 Smart TV for Korea, With Similarly Gigantic Price Tag

Anyone looking to fill half of their lounge with Samsung LCD just got a new size to choose. In short, if you loved the LED-backlit display of the 55-inch model, you're going to adore the ES9000, which features the same smart TV brains alongside a retractable webcam unit housed on the top edge. The bezel is a mere 7.9mm and Samsung has decided to coat the frame in a gentle Rose Gold coating which.

That premium finish is matched by a premium price tag, however, and will hit checkbooks for 19.8 million won (around $17,450). Despite the UK appearance, retailer John Lewis (which hosted the event) couldn't confirm whether retail models would be coming to its stores in the future. But if you can afford 75 inches of TV, you can also afford a quick flight to Seoul to pick one up. More here.

Olympus’s Google Glasses Competitor Is Really Nothing Like Google Glasses

If you thought Google Glasses looked bad, Olympus's augmented reality specs will make you want to drop dead. The company today announced an awkward, wearable display prototype called Meg 4.0, although it's nothing like Google's version.

Weighing in at 30g, the Olympus model has a 320 x 240 floating screen on the lenses that connects to the wearer's smartphone or tablet using Bluetooth. Google's, meanwhile, are meant to be largely self-contained, not dependent on a tether to an existing device.

The Meg 4.0 supposedly boasts eight hours of battery life, though that's kind of a technicality—Olympus actually expects people to use the glasses in 15 second spurts about every three minutes, which according to someone's math, amounts to eight hours total. It also looks kind of like a Praying Mantis Olympus wants you to wear on your face. The glasses also have an accelerometer, so they can tell which way the person sporting them is facing. But they don't have a camera, which has been one of the main features Google thus far has used to advertise its nerd shades. More here.

How To Take Photos of Fireworks With Your Phone

It just wouldn't be the Fourth of July without the climactic boom of fireworks. If you want to keep that memory all year—or at least share it with all of your friends on Instagram—these tips will help you get lovely photos with your phone, even if you're not a pro.

Some people roll up to the fireworks with a tripod and a fancy DSLR. (If you're one of those people, this handy guide from PCMag should help.) But what if the only tool at your disposal is your smartphone?Here's how to take photos of fireworks that don't suck—no fancy apps or art school degree required.

• Pick a good spot in advance: Before the fireworks even start, you should try to get yourself in a good position: staying upwind of the fireworks will keep the smokey aftermath of previous blasts from gumming up your shot.
• Get steady: Remember, you're taking photos at night so a little bit of shakiness from slower shutter speeds can turn your photo into a blurry mess. Brace yourself against a picnic table or even sit down on the ground if possible. If you're in a crowd, get cozy with your neighbor for support.
• Frame before you shoot: Figure out where in the sky fireworks are blowing up and position your phone in advance. You don't want to chase the shot, you want your phone to be in the right place already.
• Use the AE/AF lock: Once your phone's in position, don't take your shot right away. On the iPhone and many Android phones tapping the screen locks in the exposure and focus for your shot. Use one firework for metering, and then take the photo of the next.
• Don't be afraid of portrait mode: Depending on the scenery and your perspective, both landscape and portrait photos might work well—heck even experiment with crooked angles to see what gets the best results.
• Don't zoom:  Fireworks are SO FAR AWAY but the digital zoom on camera phones is only an illusion. Don't use it. You can always crop the photo later.
• Keep it native: Speaking of later, third-party apps introduce additional lag to your phone's camera. Keep your timing sharp by using your built-in camera app, and upload it to Instagram later.

The Fireworks Laws of Every State

If you're looking to blow some stuff up tomorrow, it's probably a good idea to know what sort of fireworks you're "legally" allowed to use according to state law. This map will give you all the information you need to know on whether fireworks are legal, illegal or incredibly lame in your state.

American Pyro actually has detailed PDFs that list the specific rules for each state. You'll have to look at those because while some states are totally gung ho about fireworks, others force you to make do with twinkly sparklers (or force you to make a road trip to a neighboring state). It's important to note though, that fireworks laws can vary within the state (county to county, etc.). Just because California is cool with fireworks doesn't mean Beverly Hills is.

Anyway. Read up on your state's rules and plan accordingly. Freedom won't celebrate itself (though it kinda does). More here.

Scientists Have Finally Made Stretchable Circuitry

Bendable electronics are nothing new. But if you're after an electronic party trick, you're going to want to get your hands on a new breed of stretchable circuitry.

Elastic electronics are something engineers have been lusting over for a long ol' time. It's not hard to understand why: current constraints mean that most circuits are solid or, at best, slightly flexible. Imagine the possibilities if your conductors could stretch to many times their length.

The problem is, though, that when most conducting materials are stretched, their material properties change—in fact, their conductivity typically drops by factors of tens or hundreds. That makes them practically useless.

Now, a team from the McCormick School of Engineering has changed that by loading a polymer with liquid metal. They took the porous polymer material called poly(dimethylsiloxane), that can stretch to many times its original size. Then they placed a liquid metal called EGaIn inside the pores, in turn allowing electricity to flow consistently even when the material is excessively stretched.

The new material, which is discussed in an article in Nature Communications, can stretch to twice its length without any drop in conductivity. That makes it four times more extendable than any other elastic conductor ever made. More here.

You Can Ship This Stainless Steel Table In an Envelope

When buying furniture that's easy to ship, you usually have to compromise on design, stability, and even ease of use. But Studio Toer is offering the best of all worlds with these stainless steel tables that fit inside a shipping envelope when disassembled.

The Postable Table's modular design not only lets it squeeze inside shipping packaging usually reserved for letter mail, but by simply increasing the number of panels included it can serve as either a small coffee table, or something that's actually useful for work and dining.

It seems like the perfect way to furnish a home if you move around a lot, until you consider the price. The smallest and most 'affordable' version measuring just 23-inches long will cost you $190. While the more usable 70-inch model is a whopping $870. But thanks to their flat, foldaway design, shipping is just $20 all around the world. More here.

Would You Use This Curved Keyboard?

WMPowerUser is reporting that Microsoft's research team is working on this curved software keyboard, leaked from an internal presentation. It even speculates that it might be made available in Windows Phone 8.

It's clearly designed for single-handed use, following the arc of the thumb across the screen and presumably using predictive algorithms to make up for what would surely amount to a lot of mistakes. Whether it's real or not is, of course, up for debate, as is the validity of the concept. I think it's a neat idea in theory, but that in reality it would be hateful to work with. More here.

Users Reporting BBM Down, Joins Instagram in Being Less Social

First Netflix, then Instagram, now BBM? There are reports along with plenty of Twitter noise that the popular BlackBerry service has headed south. This makes for one heck of an anti-social weekend if you're a photo-sharing, BBM-er for sure. More here.

Check out the response:
Today, we experienced a service issue which may have affected some of our customers in certain parts of Europe, the Middle East and Africa. Some minor issues relating to browsing and BlackBerry Messenger may still persist, but all other services are operating as normal. We apologize to any customers in these regions who may have been inconvenienced.

This Combo Trackpad-Mouse Combo Is Either Twice As Awful or Half As Good As a Regular Mouse

There's no way Gigabyte's Xenon Dual Mode Touchpad Mouse, that is a trackpad and mouse in one combination, can be any good, right? The mouse looks like a complete horror show, like using an angular Magic Mouse, and the trackpad looks neutered and drooping. I don't believe.

Gigabyte says that the Xenon is world's first dual mode touchpad/mouse action, which seems sort of cool but probably foreboding on why this Frankenmouse didn't exist before. Still, there are possible use cases: balancing the touchscreen friendly Windows 8? Dabbling in some multi-touch before needing the accuracy of the mouse's 1000dpi mouse tracking? Being bipolar about mouse and trackpads?

The Xenon is pretty cheap at $40 but I can't help but think it's either ruining two independently good things or combining together to create awfulness. Works with PC, not with Mac. More here.

A Self-Heating Butter Knife: Genius or Overkill?

The knife, designed by Warburtons, heats up to 41.8 degrees Celsius, powered by AA batteries in the handle - and melts the butter just enough to spread smoothly, without gouging holes in the bread.

A button on the handle activates the battery-operated heating element and a flashing LED indicates it is on. The prototype can spread a slice of bread in 30 seconds - although it's not clear when or if it will be released, or how much it will cost.

At first, I thought that this electric butter knife—which heats itself to an optimum temperature (41 degrees celsius) in under 20 seconds—was nothing more than a frivolous byproduct of first-world culture. But the more I think of my epic struggles with a cold stick of butter sometimes, the more I think I like it.

The World’s Smallest 4K Camera Fits in the Palm of Your Hand

4K resolution video will be the next big technological leap as far as film and television goes. But it doesn't take a massive, expensive camera like the RED Epic to shoot 4K resolution video. In fact, Point Grey's Flea3 webcam—equipped with a Sony Exmor R sensor—is up to the task but is hardly bigger than an inch in any direction.

The technical feat here is that the camera is able to push video to any compatible, USB 3.0-equipped device in real-time—something that requires a fair amount of bandwidth. Obviously, resolution isn't everything, and you probably won't be shooting cinematic masterpieces with this diminutive beast, but if you need a little extra size and clarity from your image, this might do the trick. Though at $945, the only interested parties might be businesses with video conferencing and surveillance needs. More here.

Do You Still Wear a Watch?

Watches are, for the most part, a redundant technology. We have digital timekeepers in front of our faces pretty much all the time. And yet, the watch still persists—because of tradition, an appreciation for fashion and design, or straight up novelty. So why do you have a watch on your wrist ?

Nanoscale Microwave Transmitters Will Transform Your Phone

To pump out all the radio-frequency signals that let you make phone calls and consume the internet wirelessly, your phone uses small chunks of silicon to create microwaves. Science had pushed the little things as far as they could—but now a nanoscale version promises to make your phone smaller, cheaper and better-performing.

A team of UCLA scientists has developed a microwave oscillator that uses the spin of electrons, rather than the more conventional charge, to create radio-frequency waves. While that might not sound particularly impressive, it brings with it some major benefits.

First off, it means the oscillator can be 10,000-times smaller than those that are used at the moment. That is a pretty amazing leap in size, and it means that the devices will finally make their way on to integrated circuits—as their size and design is compatible with current chip manufacturing standards.

They also create much sharper frequency outputs. In turn, that means more data can be crammed into the same bandwidth from a device using such technology, and that there's less noise so they provide a cleaner voice and video signal.

Unlike many of these kinds of technological leaps, there's no obvious barrier which could get in the way of the science being translated directly into practice. But you can certainly expect somewhat of a wait before it makes its way off the researcher's bench and into your phone. More here.

Curly Hot Dog Roasters: A More Refined Take on Your Childhood Summers

For $22 you can recapture some of that childhood nostalgia in a more refined way. Made from stainless steel, the roasters have a playful, pigtail screw on the end where you stick your sausage. They're 34-inches long, so you're not going to burn yourself, and they come with a leather carrying strap. It's quite the upgrade from the improvised campfire tools of your youth. More here.

Scientists Create Wi-Fi That Can Transmit Seven Blu-ray Movies Per Second

If you think your home Wi-Fi connection is fast, think again. Scientists have been working on a new way to transmit data wirelessly, and they can now transfer a scorching 2.5 terabits of information per second.

That's over eight times faster than Verizon's fastest wired home internet connection, FiOS, that only manages a paltry 300Mbps. Or, to put it in real terms, it's the same as transmitting seven full Blu-ray movies per second. Basically, this shit is crazy fast.

The team of American and Israeli researchers have used a neat new concept, where the electromagnetic waves that usually carry data are twisted into vortex beams. ExtremeTech describes the concept well:
These twisted signals use orbital angular momentum (OAM) to cram much more data into a single stream. In current state-of-the-art transmission protocols (WiFi, LTE, COFDM), we only modulate the spin angular momentum (SAM) of radio waves, not the OAM. If you picture the Earth, SAM is our planet spinning on its axis, while OAM is our movement around the Sun. Basically, the breakthrough here is that researchers have created a wireless network protocol that uses both OAM and SAM.




The combination of the two provides some amazing possibilities. So far, the researchers, from University of Southern California, NASA's Jet Propulsion Laboratory, and Tel Aviv University, have twisted together eight data streams, each operating at 300 Gbps, to achieve the new record of 2.5 terabits per second. At the moment, they've only transmitted signals as far as 1 meter. That should be scaled up before long—though the researchers admit 1 kilometer is probably an upper limit.

What's perhaps most interesting is that the technique can be used to twist together an awful lot of slower data connections.

Of course, all that remains is for the team to develop the technology into something robust enough to use on a commercial scale—and there's no telling how long that might take. More here.
