  • Lithium-Air Battery interest increasing

    PolyPlus aqeuous lithium air battery

    Back on July 8th I posted an article talking about the benefits of a new battery technology I had read about on weblog called Technology Review (originally published on June 26th from MIT). It think it may have originally been linked to either Slashdot or The Register. The blog entry was essentially like a press release from a company in California named PolyPlus. They had just announced the project to create single use high energy density Lithium-Air batteries for the military (most likely for radio communications in the field). The key technology was a new way to wrap the lithium cathode in a waterproof seal while still exposing it to the surrounding air encapsulated in the battery. It seems now some other big monied interests have caught onto this new battery chemistry and are going to produce it as well, but maybe not as a single use battery but instead as a rechargeable battery.

    IBM is in the news touting the promise of the lithium-air technology as a potential technological nirvana for autmobile drive trains. Estimates are a 10X increase in energy density per kilogram of battery electrolyte material. If this can be achieved, watch out electric vehicles here we come.

    Lithium-ion batteries have the potential to deliver about 585 watt-hours of electricity per kilogram, while lithium-sulfur has a theoretical potential of about 2,600 watt-hours, and lithium-air batteries might reach targets well above 5,000 watt-hours.

    If they can be perfected, lithium-air batteries would be ideal for transportation applications, given their potential for high energy capacity and low weight. And, unlike zinc-air batteries, it should be possible to make them rechargeable.

  • Acrossair on the iPhone

    It looks like the iPhone OS 3.1 is going to do nothing more the open up the video feed on the camera so that you can overlay data on top of that video. In essence, the Augmented Reality is using your iPhone’s video as a “desktop” picture and placing items on top of that. Acrossair’s iPhone App, Nearest Tube uses the OpenGL libraries to skew and distort that data as you point the camera in different directions, thus providing a little more of a 3D perspective than say something like Layar which I have talked about previously on this blog. Chetan Demani, one of the founders of Acrossair also points out going forward any company making AR type apps will need to utilize existing location information and pre-load all the data they want to display. So the nirvana of just-in-time downloads of location data to overlay on your iPhone video image is not here,… and may not be for a while. What will differentiate the software producers though is the relevancy, and accuracy of their location information. So there will be some room for competition for a quite some time.

    He went on to say that it’s pretty simple to do AR applications using the new 3.1 APIs, due out in September. ” It’s a pretty straightforward API. There’s no complexity in there. All it does is it just switches on the video feed at the background. That’s the only API that’s published. All we’re doing is using that video feed at the back. It just displays the video feed as if it’s a live camera feed.

  • Toshiba Announces World’s Largest SD Card – Gadgetwise Blog – NYTimes.com

    SDXC is yet another memory format all manufacturers will have to adopt. Isn’t it frightening how much the removable memory market has fractured into mico-formats for memory cards. About a week ago I was playing with an Olympus voice recorder at work. It had it’s own funny shaped memory cards you had to buy from Olympus if you wanted to increase the storage size. One positive thing I will say though is this. SDHC at least has consolidated some of the mindshare around a commonly supported form factor for removable storage. Compact Flash once enjoyed a similar amount of support. But nowadays you cannot even find a laptop with CardBus slots anymore. Many add-ons for laptops are installed on internal PCIe busses now.

    I hope all the device manufacturers get onboard with the SDXC format only because of the limits on the FileSystem on these cards has needed to adapt to the vagaries of long form video shooting. I remember the painful days of 4GB file size limits for video. That took a long time to dissapate on the desktop computer. It’s high time it disappeared on digital video cameras as well.

    Toshiba says all three new cards will bring a maximum write speed of 35 megabytes per second and a read speed of 60 megabytes per second. For videophiles, the new SDXC format will enable video files to extend beyond the current limit of 4 gigabytes.

  • AppleInsider | TomTom for Apple iPhone released in U.S. App Store for $99

    Apple Insider reports this morning that the TomTom GPS application has appeared in the U.S. AppStore. And if you decided to get the external antenna you can even use your iPod Touch as a GPS. That is way cool and way more useful than I had previously thought this was going to be. Kudos for TomTom to make the thing more widely available on the iPhone platform.

    The product works with the iPhone 3G and iPhone 3GS, which include an integrated GPS receiver. It will reportedly also be compatible with the first-generation iPhone and the iPod touch once the separate combo hardware kit is made available. TomTom has not yet announced a price for the hardware package.

  • AppleInsider | Apple’s tablet

    Theres no way the tablet will be as hot as the iPhone
    There's no way the tablet will be as hot as the iPhone

    Market projections are a black art. How big is the market for an as yet unreleased product? Marketing departments always have to do the  research and focus groups and test marketing to see what the projections are. But even these can be wrong or misleading. Based on this article one Wall Street analyst firm bases their projections on the market for the Apple TV a niche product if there ever was one. In the first year of it’s production the Apple TV sold 1.2million units. Given the appeal of the iPhone and iPod Touch, the projections are the Mac Tablet will sell far better than the 1.2 million units of the Apple TV. And with a list price of ~$600 US then the revenue generated would be approximately 3% of total revenue. This is all pad on paper estimates based on the up take of a somewhat less successful product, so it could be way off the mark. I’m hoping there’s something new, something nobody has guessed at so far that Apple will include in this device that will help really, really differentiate it. It should be unlike other tablets, and unlike its little brother the iPod Touch.

    We believe an Apple tablet would be priced 30%-50% below the $999 MacBook, and would offer best in class web, email, and media software,” the report reads. “In other words, we believe Apple’s tablet would compete well in the netbook category even though it would not be a netbook.”

  • Reseller lists TomTom iPhone kit

    Not an iPhone, but definitely a lane assist!
    Not an iPhone, but definitely a lane assist!

    It’s not cheap, but the TomTom accessory kit for the iPhone 3GS is now listed on a re-seller’s website. Hopefully the Navigon and AT&T iPhone Apps haven’t stolen the thunder of the original TomTom announcement. But I guarantee the GPS performance will be a lot faster with an external device. I’m not criticizing the internal GPS on the iPhone. It is a compromise design that allows everything to sit and play well within the same old iPhone footprint. For good GPS reception and quick locks on satellites, that compromise is going to get in the way. Especially for anyone who has used purpose built, standalone model GPS navigators. My fingers are crossed in hopes the TomTom at least matches the low end of the navigator market with its hardware/software combo.

    The application is said to take advantage of iPhone OS 3.0’s support for true, turn-by-turn directions. The software will have both nation-specific and international maps from TomTom, will work in either landscape or portrait modes, and give voice directions.

    The software will reportedly be available for separate purchase from the App Store, and would rely on the iPhone’s internal GPS receiver. The hardware kit, however, comes with its own, separate GPS. It will be one of the first external accessories to take advantage of iPhone 3.0’s capabilities.

  • iTunes U: The Beginning

    It’s interesting to see how the whole iTunes U structure works. I’ve been reading documentation about the ‘web services’ enabled within iTunes U. It completely replicates the GUI functions but through a semi-automated interface. Reminds me a little of how you can change the underlying LDAP directory structure using LDIF commands or LDIF files with all the changes embedded within it. In iTunes U, you do an HTTP PUT securely with a signed token, and the iTunes U Web service sucks that up and executes all the commands embedded within your XML file that you put. Very powerful, but very scary too as these changes are made to your production environment. So there’s no real easy way to test the results of your commands without just taking a big risk, leaping in and seeing what happens. This is like SQL commands where you DROP TABLE, not a fun thing to do. DROP TABLE is a big black whole that makes your data disappear in an unrecoverable way. iTunes U has similar functions where you delete the structure AND the data at the same time. You may restore the structure (by backing up your data tree in XML format), but the data embedded within the tree, well that’s gone. So restoring stuff is going to be impossible if you get the syntax wrong in your XML file. The only real benefit to me now is the ability to get a listing of the whole site structure using the Tree command and then forcing an update to any groups that are of the type RSS Feed. The update will be necessary if anyone adds files to a podcast being hosted on servers within our institution.

    I discovered or re-discovered a tool called Woolamaloo which was introduced to me during the Apple iTunes training. University of Illinois Champaign-Urbana created it to allow you to use a GUI to control the Web services from a desktop OS. This is good as I was at a loss to adapt the sample code into anything like a reliable generator of tokens to send to iTunes U web services. I couldn’t figure out what parts of the java example to comment out and recompile. Starting this Monday I’m going to put Woolmaloo through it’s paces. If I can force the RSS feeds to update on demand when somebody has a problem updating their Podcast feeds, I can at least speed things up. But I’m still very leery of deleting or merging any section. I will copy so I can make a course appear in more than one place without using the iTunes multi-click interface. But I will not delete or merge.

    And just today I also discovered there are Apple Automator scripts readily available that add a graphical layer on top of all the web services goodness. So now I can integrate a bunch of steps from uploading bunches of files, forcing RSS feeds to update to merging/rename whole sections all from Automator. I’m going to test it and se how good it really works.

  • Tablet device coming early next year

    True to form, Apple is keeping a tight lid on their Mac Tablet. But all rumors are pointing to a release early in 2010. The announcement of the device may come in September of this year at the point where new iPod products are announced. Other scuttle-butt indicates Verizon may be providing it’s Fourth Generation (4G) network for the new device so that it can stay connected to the Internet wherever Verizon cell phone towers are available. It will be interesting to see how the market might fracture between cell phone and tablet users. I would guess this whole project may turn into an Macintosh Cube experience where Jobs reach exceeded his grasp.

    This is how big the 10" tablet might be

    However, the past six months have reportedly seen the critical pieces fall into place. Jobs, who’s been overseeing the project from his home, office and hospital beds, has finally achieved that much-sought aura of satisfaction. He’s since cemented the device in the company’s 2010 roadmap, where it’s being positioned for a first quarter launch, according to people well-respected by AppleInsider for their striking accuracy in Apple’s internal affairs.

  • My love letter to Public Television

    The days I spent watching educational programs on PBS I think gave me an interesting way of seeing the world. And I am not alone:

    Exposure to Samuel Beckett, art-appreciation documentaries, “Masterpiece Theatre,” and grade Z film gave me the rudiments of an aesthetic education. And a good thing, too, because nobody in the local school system would have used the expression “aesthetic education,” or considered it worth offering.

    via Views: The Plug-In Syllabus – Inside Higher Ed

    Those were golden halcyon days watching the weird shows fly by. I remember seeing Firing Line briefly and Steve Allen’s program and Dick Cavett’s program. I’m not saying I ‘watched’ them, but I would see them in passing hoping to find a repeat of Sesame Street. My parents would watch Masterpiece Theatre religiously, which I hated because I wanted to watch what else was on Sunday nights. Usually it was NBC’s Police Story or some other violent, low-brow entertainment.

    Now all that old TV “content” can be recycled to the public airwaves of the Interwebs. All that was old is new again. Which means I should try tracking down all those old episodes of Omnibus that made the transition from BBC to PBS. Sometimes I think PBS and BBC should have formed up a single International Media conglomerate and shared more costs in preparation for the large scale media consolidation of the ’80s. And certainly they could have hedged their enterprises somewhat against the proliferation of Satellite and Cable TV networks.

    Oh, if I could  just get the BBC for several hours in the evening or even during the day. I would watch Emmerdale or Eastenders, I would even watch Tesco commercials. Doesn’t matter to me. Too much of what we watch locally on TV is a kind of bubble like prison, meant to reinforce, nay indoctrinate one in the predominant culture. And more choices hasn’t helped as the media owners don’t let the media flow freely cross international borders.

    Welcome to Internet U, via Video

    I was raised on the most successful initiatives from Public Television, or ETV as it was previously known (E standing for Educational of course). Sesame Street, 3-2-1 Contact, Mister Rogers’ Neighborhood, and Reading Rainbow were my bread and butter as a kid. And yet while those educational programs were major successes, television’s promise of bringing education and instruction to a wide audience was left largely unfulfilled in the United States. Proponents of educational TV faced the harsh realities of the large amounts of funding required to create and maintain television programing placed upon them. The need to satisfy the large …

    As a kid I watched PBS a lot. One reason being in the 1970s funding for PBS kids shows and educational programs was better than it is now. As kids we would watch hours of programming and then we would be rewarded, REWARDED with a fund-raising drive once a year. The reason I say rewarded is PBS went out of its way to entertain and bring in new viewers. They would air special programs especially for the fund-raising drive. I remember one year they aired Woodstock as the centerpiece of one year’s fund-raising campaign. That was the cool part, you never knew what they would pull out to reward us when they were asking for money. And what did we get in return?

    WGBH, the Boston superstation for PBS and WNET 13 in New York would crank out the jams. Some of it was experimental, some of it was just downright good. There was Sesame Street, Mr. Roger’s Neighborhood, Electric Company, Zoom and eventually 3-2-1 Contact. And even in school our teacher’s would fire up the TV in the days before the VCR to show us certain science programs different times of the week. Sometimes it would be a reading program, or a science program. At one point during the Carter Administration, all the kids were encouraged to learn the Metric System. So for about one year we watched  a program once a week to teach us the metric system. Turns out we didn’t go metric.

    After school was good too. We had a TV show produced by a “local” TV station in Sioux Falls, SD. It was hosted by the weatherman on KELO-TV. It was called Captain 11. I knew kids who had gone down to Sioux Falls and gotten on the TV show. And there was also a drawing for a prize on each episode. It was a giant plastic tootsie roll with tootsie roll lollipop candies inside. I never saw any of my friends on that show. But it wasn’t for lack of trying. I saw every Hanna-Barbera cartoon, and a few Our Gang short films along the way. Why I spent more time watching TV than I can even add up. It’s a lot that’s for sure.
