Researchers find weak point in lithium-ion batteries, suggest better nanowires could be the answer

We’ve seen countless attempts to build a better lithium-ion battery, but there’s been far fewer research efforts devoted solely to figuring out why lithium-ion batteries don’t last longer. A team of scientists at the Pacific Northwest National Laboratory have been doing just that, however, and they’re now sharing some of their findings. The main culprit, they say, are the nano-sized wires made of bulk tin oxide used in the batteries, which can expand and deform considerably over time, eventually rendering the battery useless. What’s more, while the research was focused primarily on examining the cause of battery aging, the researchers do naturally have a few suggestions on how to improve them — namely, to replace those wires made of bulk tin oxide with finer tin oxide nanowires. As lead scientist Chongmin Wang explains, that would effectively amount to winding together “thinner wires rather than making one thick rope,” which is of course easier said than done. Head on past the break for the complete press release.

LaCie Float concept combines external HDD with trackpad, ingenuity with fantasy

How do you freshen up the typically unexciting external storage unit? You slap a multitouch trackpad on the top of it, of course. And since you’re dreaming up wild concepts, make that top out of carbon fiber, provide a base made out of glass and insert some LEDs next to it to provide ambient illumination — with an integrated light sensor adjusting their brightness on the fly, obviously. Yes, André Silva’s LaCie Float is indeed out of touch with things like “feasibility” and “economics,” but don’t tell us you wouldn’t love that slice of converged awesomeness sidling up next to your laptop. USB 3.0 comes standard and an SSD option is also available, if you wish for it hard enough.

Panasonic TV Records Straight to SD Card

We might still say we’re “taping” a TV show, but unless you’re my parents, who still watch old Star Trek: TNG episodes on VHS, then you will have thrown out your VCR years ago. But what if you want to record something, and you don’t have a TiVo?

Then you buy one of Panasonic’s Viera G3-series TVs, which lets you record direct to an SD card. The first set is the 42-inch TH-L42G3, and it will rip hi-def TV-shows to SD, SDHC or SDXC cards at up to 1920×1080 resolution at 24Mbps. A 64GB card will hold five hours’ worth of video.

Should $200 for a 64GB card be a little steep, there’s also a USB port so you can hook up a regular hard-drive — a less portable but probably more practical solution.

Otherwise, the TV sports all the usual modern niceties: two HDMI ports, Ethernet, an IPS, LED-backlit display for a wide viewing angle, and Panasonic’s own Viera-link, which lets you hook up compatible cameras to view slideshows and video directly.

The G3 TVs will ship to Japan February 18th 2011.

Oh, and if you are my parents, the Christmas parcel arrived, thanks. There had better be some chocolate in there, is all I’m saying.

Word Lens: iPhone App of the Year?

word lens.jpg

Here’s a belated entry for those of you who are compiling year-end best of mobile app lists. People are tossing around words like “magic” and “future” upon giving Visual Quest’s new app a spin, and we’ve got to say, from demos we’ve seen, we’re pretty impressed.

Word Lens is an augmented reality language translator–hold it up in front of a sign in a different language, and the thing will translate it in real time. All in all, it’s pretty fantastic, and a lot more useful than most of the games and other apps that tend to dominate the iTunes sales lists.

The app itself is free, but there’s $4.99 fee for Word Lens’ various language packs. At present, the app only does Spanish to English and English to Spanish. More languages will be coming soon.

Octavio Good, a developer behind the app explained its process thusly, “It tries to find out what the letters are and then looks in the dictionary. Then it draws the words back on the screen in translation.” Neat.

Yahoo! Messenger and ooVoo Mobile do video chat on Android, but only for a lucky few

Yahoo! Messenger and ooVoo Mobile do video chat on Android, but only for a lucky few

Two video chats enter the ring, only one comes out. In this corner it’s ooVoo Mobile, a portable version of the (somewhat) popular desktop video chat application that will let up to six users simultaneously swap bitrate over 3G, 4G, or WiFi — but only if you have an HTC Evo or Samsung Epic. In the other corner it’s Yahoo! Messenger, with version 1.3 adding video calls and similarly limited device support, though this time it’s the myTouch 4G and the Evo getting the nod. So, Android owners, which of these is going to reign supreme? Or, are you going to tap out and stay cozy with Qik? Hit the Android Market now and place your bets.

Update: We’re told that Paltalk has also recently released an Android app to the Marketplace, giving you yet another way to say “hey.”

Gadget Lab Reader Makes iPad Kitchen Stand, Starts Business

Roland Heersink had a problem. He wanted to use his iPad in the kitchen, but his wife vetoed any and every space-hogging countertop stand. So Roland, smart Gadget Lab reader that he is, decided to make his own. And not only did he come up with the The Original Kitchen iPad Rack. he turned it into a business.

Roland’s rack takes up precisely zero space on the countertop, instead suspending the tablet from the overhanging kitchen cupboards. The rack comes in two pieces of clear acrylic. One attaches permanently, out of view, beneath the cupboard. The other hooks onto this mount and forms a sloping or vertical stand for the iPad, keeping it handy, but out of the way of spills. When you don’t need it, just toss it into the cupboard above.

The rack will cost you $30, and should you have a big kitchen, you can choose kits with two or three mounting brackets, at $5 extra per bracket. I think Roland’s idea is pretty ingenious and, if coupled with my own low-tech waterproof iPad case, would make for an almost indestructible kitchen iPad setup.

Sharp investing $1.2b in expanding smartphone LCD production, Apple fingered as the major client

Apple’s practicing its self-imposed rule of supplier polygamy this week and Japan’s Nikkei is telling us all about it. It started off on Monday, when we learned that Toshiba’s throwing down some cash to build a new smartphone display production plant, with Apple as the key investor and subsequent consumer, and today we’re hearing pretty much the same story, only with Sharp playing the role of Japanese producer to Apple’s hardware whims. A “large portion” of the $1.2 billion cost — identical to what Toshiba’s said to be spending — of expanding Sharp’s Kameyama factory is expected to be shouldered by Jobs’ cash-rich crew, a postulation also confirmed by Reuters, who’s managed to dig up a pair of sources agreeing with the Nikkei. Our Japanese team reports that Sharp has made its expansion plans official, but obviously there’s nary a peep about any Apple connection, while DigiTimes says Toshiba has outright denied any involvement with Cupertino. Guess we’ll just have to wait for the iPhone 7 teardowns to find out.

Alexa Improves Traffic Details Page

This article was written on February 20, 2007 by CyberNet.

Alexaranking1Just a few days ago, Alexa added some noticeable improvements to their Traffic details page. This information is helpful to publishers, and gives them a better idea of who their traffic is, and where it’s coming from.

One of the first things you’ll notice is that you can see where traffic is coming from geographically.  For example, I pulled up the traffic rankings for CyberNet, and it shows that 38.8% of our traffic comes from the United States, 9% is coming from the UK, 5.5% comes from India, and the rest is broken down among several other countries.

Not only can you see where the users are coming from, but you can also see how your website ranks in other countries.  Today in the United States, we’re ranked 16,855, but in India we’re ranked 12,484, and in the United Kingdom, we’re ranked 19,281.  Now we have a better idea of how we stand both in the United States and else where.

Another major change is how Alexa expresses how many people have been reached.  Previously, it showed the reach per million. That number always confused a lot of people, so now it’s being shown as a percentage. For example, it shows that yesterday, we reached 0.004% of the people on the Internet. Another example is MySpace which is ranked 5 on Alexa, and yesterday they reached 4.74% of the people on the Internet.

All of this new information is helpful for both publishers, but also potential advertisers who are wanting to advertise on a site.  Advertisers like to know the demographics, and this is one way that they can get them. As a publisher, it’s always nice to know where traffic is coming from geographically, and now Alexa provides more detailed information specifically for this purpose.
