Utah Researchers Throw Cold Water On Rosy OLED Efficiency Rates [Dim Bulb]
The issue lies with the theoretical efficiency ceiling assigned to OLEDs in a 2001 paper published in Nature. That paper suggested OLEDs would eventually be capable of converting 41 to 63% of electricity passed through them into light. The current ceiling for OLEDs is 25% efficiency, and that is where the most recent research out of Utah says it will probably stay.
In the end, all this talk of percentages and efficiency might be moot, especially considering OLEDs main purpose will be to replace LCD screens, not illuminate rooms or serve as the running lights on an Audi A5. OLEDs are also a superior light source for flexible materials, so there's that, too. They just won't be lighting up any kitchens or anything like that anytime soon.
To summarize, the future appears bright—for both LEDs and OLEDs. To each their own, we suppose. [NewsWise via CrunchGear]
Does one reach for a camera or a can of RAID when the Lexus Nuaero concept pulls into the driveway? Sure Jon Rådbrink's design looks incredibly cool, fast and futuristic; but then again I've also spent the last few minutes looking over my shoulder to see if Sigourney Weaver was about to burst from the wall in a load lifter to do battle with it in my office. As it turns out, there's a lot more to this design than just looks, and Rådbrink believes the car's "low weight and large presence" will be the way premium cars could be manufactured in the future. Oh, and it's loaded with tech, too.
The kicker is that this 14.5-ft. car is designed with lightweight materials meant to increase mileage and efficiency. How light is light? Try roughly the same weight as the diminutive SMART fortwo. "I believe that this design paradox of low weight and large presence could be the way we'll define premium in the future," Rådbrink said. Just don't forget the futuristic airbags if this ever makes it into production. [
A release date and price has been set for UMPC contender Gigabyte's MID M528, a diminutive portable computer with a slide out keyboard, according to the folks over at UMPC Portal. A product page on Gigabyte's site put the cost at $689 and availability on Sept. 17. The page then disappeared, but not before intrepid internet surfers could get a nice screen grab.
AC manufacturer Greencore has come up with a long-awaited solution to 
Fujitsu Siemens looks like it's about ready to launch the svelte Amilo Mini. According to IDG News, the company has announced a press event for August 28 at the IFA show in Berlin, and the signs and portents indicate a big reveal could happen at that time. The specs don't really differentiate the Amilo Mini from the plethora of other ultra portable notebooks hitting the market these days, but it does boast changeable face plates (brown, black, pink, and red). Cost is expected to fall between $600-800. [
The Buenos Aires government would have done the late Owen Lars proud with their newly installed $5 million Intelligent Monitoring Towers. Designed to collect information about the city's air and noise quality, we can easily see these 42 towers being at home 
When the program is fully functional by the end of 2008, city officials expect to have a complete map of the environmental quality of the city. They'll use that info to influence bus routes and improve overall quality of life for citizens. No word yet on whether that will require any power converters from Tosche Station. [
