HTC Lithium-Ion Battery Burns Hole -- in Geek's Pants!


The owner of a HTC Touch Pro smartphone recently made a startling discovery when preparing his laundry this week. After noticing an acrid aroma emanating from his pile of clothes, he discovered a charred hole in the back of his jeans. The man, identified as PPCGeeks user kidmet, might want to invest in some asbestos underwear.

He had reportedly been carrying a spare lithium-ion battery, which he said was an authentic HTC, that expanded and burned through the back of his pants. We're sure he must be upset about the loss of a good pair of jeans, but the alternative, if he'd been wearing them (especially in the front pocket), could have been disastrous.

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.

Green Tech to be a Major Theme at Next Week's Gadget Show


green tech to be a major theme at cesNot like we couldn't see it coming, but news is that a big theme at this year's CES will be "green technology." The environment, being green, and global warming have been on everyone's minds this year. The Prius, 'An Inconvenient Truth,' OLEDs, and tons of research into alternative power sources and fuels were all the rage in 2007, and '08 doesn't look to be any different.

A number of new technologies are expected to make their debut, or at least US debut, at CES next week. Among them is a new Silver-Zinc battery technology that will increase battery capacity by up to 30 percent, and will also yield more recoverable metal when recycled than the currently common Lithium-Ion batteries.

Fujitsu will show off a laptop with a plastic case made partially from corn byproducts. The case will not be biodegradable, because it still contains petroleum based plastics, but when the case is recycled the petroleum based plastic mixed in with the corn will separate and the corn plastic will be biodegradable.

Even cell phone chargers are getting a green makeover. As much as two thirds of the power drawn by a phone charger is wasted because AC adapters continue to draw energy even after the phone is fully charged. A company called GreenPlug will show off a universal hub that it hopes to convince electronics companies to support. The hub works by "talking" to devices to determine how much power they really need. Another perk is that the universal hub could eliminate the need for carrying a separate adapter for every phone, iPod etc. However one very un-green side effect is that the hub, even if supported, just means more non-biodegradable plastic going into circulation.

FAA Institutes New Bans on Laptop and Gadget Batteries on Planes

FAA Institutes New Bans on Batteries

In the wake of exploding batteries in some laptops, airlines are taking measures to ban the use of those laptops in flight. For the year 2008 a new FAA-wide battery ban has gone into effect, and this one potentially applies to all of your gadgets -- not just your laptop.

The ban doesn't focus on a specific manufacturer or model. The new rules dictate how much lithium you are allowed to carry on a flight, and how you are permitted to do so. Lithium is of course a key component of rechargeable lithium-ion batteries, and with these new rules you are allowed to carry on and check a maximum of 25 grams of lithium.

How do you figure out just how much you have in all your gadgets? Well, there are some guidelines and examples at Safetravel.dot.gov that can help you get a good estimate, but unless you always take three or four spare batteries for your laptop along with you, chances are you have nothing to worry about.

However, it's important to note that spare batteries cannot be stored in checked baggage. So, while you can still take a second or maybe even a third laptop or cell phone battery with you, you have to keep it in your carry-on baggage, or risk it not being there when you get to your destination!
