Cop Attacks Man for Facebooking His Wife

Reading your significant other's e-mails, texts, or Facebook messages usually turns out to be a bad idea. For example, a police officer in Martinsburg, West Virginia didn't take too kindly to some 'friendly' Facebook exchanges between his wife and a mutual friend. While some would simply talk it out, this cop allegedly decided to let his fists do the talking.

According to Your4State.com, Lieutenant John Sherman, while off-duty, confronted Larry "Tike" Murphy about the messages last Thursday. After a heated exchange, Sherman allegedly punched Murphy in the face and back, and ripped his shirt (and right by the Martinsburg Church of Christ, no less). As a result, Sherman was placed on administrative leave and charged with battery. According to court documents, Sherman "did not believe it was right that another man was communicating with his wife by Internet-sending some of the things he was sending to her."

Why Laptop Batteries Don't Last as Long as Claimed

More Accurate Battery Test for Laptops in Our Future?
Anyone who has shopped for a laptop knows that a manufacturer's estimated battery life is estimated pretty liberally. Usually, the numbers are based on a test called MobileMark 2007, which measures how long a computer's battery lasts under conditions that are, to be polite about it, completely unrealistic. The screen is set to 20-percent brightness, Wi-Fi and any other wireless tech shut off, and all apps are turned off. As the New York Times said, "it turns a computer into a dimly lit clock."

The problem is that nobody simply sits in front of their laptop staring at a blank screen. In fact, most users treat their laptops just like a desktop PC. Most users listen to music, instant message, and browse the Web (all at the same time) with the brightness pumped up to 100-percent. It's no surprise that when manufacturers claim battery life is around six hours, it .

Future Cell Phones Could Pull Electricity Out of Thin Air

Furture Cell Phones Could Pull Electricity Out of Thin Air
Imagine a world where plugging in your gadgets to charge them is a thing of the past. And we're not talking about "wireless" chargers, like the Palm Pre's Touchstone, which still require some sort of physical contact. No, according to Technology Review, Nokia is working on technology that would collect ambient electromagnetic radiation to slowly charge batteries.

Ambient electromagnetic radiation is given off in the form of radio waves by things like Wi-Fi routers and cell phone towers. Nokia has created a prototype device that collects these radio waves and converts them to electrical current. Current prototypes can glean between 3 to 5 milliwatts from the air, but the company believes it's only three or four years away from a commercially viable prototype that could collect 50 milliwatts. If Nokia could reach that milestone, the phone, when not in use, could be charged (albeit slowly) by a nearby TV or cell tower.

MIT-Developed Batteries Can Charge in Seconds



Some big brains at the Massachusetts Institute of Technology have developed battery technology that could change the way we charge up our cell phones, cameras and other devices, according to the MIT News.

The technology involves a change in the channeling of lithium ions through -- you guessed it -- lithium ion batteries. Created by MIT Professor Gerbrand Ceder and graduate student Byoungwoo Kang, the new battery design allows for lithium ions to speed around the surface of the battery in a way MIT News likens to cars driving around a city's expressway loop. While the new design allows particles to enter the battery's center from numerous exit ramps, conventional chargers have all those ions driving straight up Main Street. This increased efficiency in regards to time and energy allows these smaller, lighter batteries to be recharged in mere seconds, according to Ceder.

MacBook's Battery Goes Boom in London Office

MacBook's Battery Goes Boom
It's been quite some time since we've had a good exploding battery story. Back in 2007, it seemed like nobody was immune from the plague, with Sony being blamed for battery recalls extending to laptops from Apple, Dell, Toshiba, and a number of others. Given that was so long ago and the news was so widely publicized, we'd figured everyone would have, by now, swapped their recalled batteries for free replacements. Apparently, we were mistaken -- some unlucky soul's aging Apple PowerBook self-destructed in a London office yesterday, sending six-foot flames shooting to the ceiling.

The laptop apparently started smoking, then sparking, then a massive pillar of flame blew out of it that reached the ceiling. It took an entire fire extinguisher bottle to put out the flames, but even then it was still glowing red and dripping slag. It's believed that the laptop is three or four years old, and nobody is sure whether it had its battery replaced during those 2007 recalls. We're guessing it didn't.

If you have an older PowerBook and aren't sure if you need a new battery, head over to Apple's Battery Exchange site and check your serial numbers. Better to be safe than get burned! [From: The Inquirer]

Get NiMH Batteries for Your Camera



If your camera takes AA batteries, you should know that regular alkalines die in a fraction of the time that Nickel Metal Hydride (NiMH) types do. For the best possible battery performance, look for a rating of 1850 mAh or higher. And, while you're at it, buy rechargeable versions instead of landfill-clogging disposables.

Beer and Urine Make 'NoPoPo' Batteries Last 10 Years



Leave it to our clever, if bizarre, Japanese friends to come up with the NoPoPo battery.

According to Unplggd, the battery gets power when one of several fluids mixes together with its magnesium and carbon components. Among those fluids are beer, saliva and -- that's right -- urine.

Apparently, those unlikely charging agents help the batteries to live for as long as ten years. And the bizarre charging method is much simpler and more sanitary than you'd guess. All you need is a cup, the batteries and the included eyedropper. You can, we're sure, figure out where to go from there.

Even if these AAA and AA batteries wind up being less than satisfactory, the novelty itself is well worth the $15. [From: Unplggd]

Freeplay Zipcharge

Freeplay, creators of a large line of self-sufficient hand-cranked radios and flashlights, is entering the rechargables market with its Zipcharge rechargeable power stick, available in March. Co-opting tech developed for hybrid cars, the device pairs intelligent circuitry with a nano-phosphate lithium cell to achieve a swift charge time of only ten minutes, with enough juice to bring to life your depleted cellular lifeline.

With a single USB port and a variety of tips, Zipcharge shouldn't give you any problems with compatibility, but the $80 price tag could rival the price of your phone. If we could only get this battery tech in our cell phones themselves...

Check out the video after the break for a closer look at the Zipcharge.

Student's Tech Promises 12x the Battery Life In your iPhone, BlackBerry

Feeling the hurt of endlessly dying batteries on your BlackBerry (or iPhone, if that's what you're into)? Atif Shamim, a PhD student at Canada's Carleton University might have the medicine for that pain of yours. He's cleverly hacked such devices, removing all the wires that connect the electrical circuits to the antenna, and developed a module for the connection to operate wirelessly. The result, he estimates, is that his modified devices use almost 12 times less power than they normally do -- which of course means longer battery life. A paper about the device has won an award at the European Wireless Technology Conference, and Shamin has filed for a patent in both the US and Canada. There's no indication of when we might start to see tech like this on actual commercial devices, but we're pretty sure plenty of companies are going to want to get a hold of this technology like, yesterday.

Sensor-laden Footballs and Gloves Could Run Refs Out of Work


Dr. Priya Narasimhan, a professor at Carnegie Mellon University, doesn't intend to put a single NFL referee out of work, but there's no doubt that the technology she's tinkering with could indeed have that effect. The prof and her students are developing sensor-laden footballs and gloves, both of which could eventually tell in real-time whether a ball bounced off the ground before being caught or whether a player actually had possession of a ball whilst being piled upon after a fumble. Currently, she's had zero luck persuading a college or professional team to help her experiment further, and we can sort of see why. We mean, it's nice to get every call right in theory, but what fun would sport be without the all-important "Ref, you suck!" chant?

Toasting Charger: For Batteries, Not Bagels



Don't get too excited: the Toasting Charger is merely a concept, at least for now. Still, it always brightens our day to see products that call to mind this most beloved human food. Simply pop in the battery, push the lever on the side and well, that's the beauty of it... you already know how to use this little guy. There's also a helpful LED on the front to indicate the progress of the charge for the hopelessly impatient. "Toasting" your lithium-ion batteries is, at first glance, a little weird, right? Nope. Pass the jam, please.

[Thanks, Tony]

New Sony Battery Recall Affects Acer, Dell, HP, Lenovo, Toshiba Laptops

One day later and Sony's battery recall has already tripled in size. What started as a recall of 35,000, just hit 100,000 (75,000 of which are HP related) and now includes Li-ion batteries used in some Lenovo and Acer laptops as well as the original list of Dells, HPs, and Toshibas. All the laptops were sold between 2004 and 2005, two-thrids or which were sold outside the US. What's most troubling is that Sony claims the faulty batteries are from the same unit that made the recalled batteries from two years ago.

So... Apple, you next?

[Affected models include: Dell Latitude 110L, Inspiron 1100, 1150, 5100, 5150, and 5160; HP Pavilion dv1000, dv8000, and zd8000, Compaq Presario v2000 and v2400, and HP Compaq nc6110, nc6120, nc6140, nc6220, nc6230, nx4800, nx4820, nx6110, nx6120, nx9600; Toshiba Satellite A70/A75, P30/P5, M30X/M35X, and M50/M55.]

Toshiba's New Battery Gets 90% Charge in 10 Minutes


Imagine this -- you, sitting in a dingy airport terminal waiting on your flight with a lifeless laptop and just 10 minutes to spare. You've got oodles of spreadsheet work to do before 8:00AM tomorrow, and unless you get it done on this flight, you're fubared. Toshiba is looking to make said scenario seem like one that's not so grim, as its prototype SCIB (Super Charge Ion Battery) purportedly has the potential to get 90-percent full in just 10 minutes. The battery was unveiled at CEATEC 2008 in Japan, though little was known about its eventual availability. Shame development cycles can't be fast tracked in a similar manner, huh? [Via UberReview]

Electric Wheelchair Battery on Plane Combusts



We've seen no shortage of batteries exploding, whether they be in cell phones or laptops. It didn't take long for the FAA to institute bans for certain types (and quantities) of batteries for gadgets, and after an incident on a plane heading for Manchester, England, the U.K. travel administration may want to think about instituting a similar ban.

The battery on an electric wheelchair was found sparking in the cargo hold of a Boeing 757-200 that was carrying carrying 229 passengers. Thankfully, the plane had just landed when the battery started shooting sparks and flames, meaning the resulting danger could be addressed without fears of a major disaster. The wheelchair was removed from the plane, placed on a vehicle, and moments later, burst into flames. That was just dumb luck, though, and highlights the fears that lithium ion batteries of any type can go super-nova mid-air and cause some serious issues. [From: TimesOnline]
