Hidden RFID tags could mean end of bar-codes and lines at the checkout
Newly developed radio-frequency identification (RFID) technology could usher in the era of checkout line-free shopping. The inexpensive, printable transmitter can be invisibly embedded in packaging offering the possibility of customers walking a cartload of groceries or other goods past a scanner that would read all the items at once, total them up and charge the customer’s account while adjusting the store’s inventory. More advanced versions could even collect all the information about the contents of a store in an instant, letting a retailer know where every package is at any time. Read More
Board games aren’t necessarily bound to become obsolete - at least, not if researchers at Queen’s University in Ontario, Canada have anything to say about it. They will change, however. Queen’s Human Media Lab (HML) recently unveiled a prototype board game that uses traditional flat cardboard tiles (i.e: cards), but the images on those tiles are projected onto them by an overlooking digital projector. The images stay on the tiles as they’re moved around by the players, courtesy of an overlooking camera that tracks their movements. This means that the tiles could display moving video, that their display could change entirely depending on what’s happening in the game, or that it could be customized by the players. Monopoly night may never be the same. Read More
Next-generation TMOS displays closer to mass production
Uni-Pixel, a company based in Woodlands, Texas, has announced it is about to start mass production of a thin-film to be used in time-multiplexed optical shutter (TMOS) displays, a next-generation display technology that exploits retinal persistence in the human eye and promises significantly better performance than CRT, LCD and OLED displays with, among other things, great durability and dramatically improved energy efficiency.

E-readers are a welcome alternative to lugging around paper-bound tomes when on holiday, as they can store volumes of reading material in one handy, pocket-sized (well almost) device, and offer users the possibility of hours and hours of uninterrupted reading pleasure. That is, of course, until the battery runs out. LG Display has developed a solar cell capable of extending the battery life of an e-reader, possibly making the anxiety of a blank screen on the last page of that captivating thriller less likely.

In the face of legislation being enacted around the world, the future of the trusty incandescent light bulb has been looking dim. Ireland has banned the sale of incandescent bulbs, and the United States is set to phase them out by 2012. And it’s no wonder - the apple of Thomas Edison’s eye is something of an energy hog, especially when compared with modern bulbs such as compact fluorescent (CFL) bulbs and LED-based lights. But now a new technology from Deposition Sciences Inc of Santa Rosa, California, is promising a brighter future for the venerable incandescent. Read More
Scientists developing flexible, large area, cost-effective, reel-to-reel printable plastic solar cells have announced that trials have commenced which promise a new era of solar cells that are printed like money. These printable solar cells offer advantages over traditional solar technology because of the potential to mass produce the cells cheaply using polymer printing technology, a process which has already been used in banknotes in more than 20 countries.

Arizona is now home to the world’s largest solar array using Copper Indium Gallium diSelenide (CIGS) thin-film solar cells. The 750-kilowatt (kW) system, located at Global Solar’s manufacturing facility in Tuscon, is the first commercial-scale deployment of the company’s CIGS technology. Read More
Germany is again making news in the solar field with the announcement of the industry’s first ever Gen 8.5 (5.7 meter square) silicon thin film solar PV module at Signet Solar’s new factory near Dresden. The accomplishment at the company's 200,000 square foot production facility and is another step towards lowering the cost of renewable solar energy through thin film technology. Read More
May 15, 2008 Advancing a viable market for photovoltaic solar energy involves a balancing act between creating efficient solar cells and at the same time reducing the cost of the manufacturing process. Solar efficiency has been demonstrated to levels as high as 22% (a record set by SANYO last year), and although HelioVolt Corporation's latest announcements concern technology that is only delivering 12.2% conversion, the company has made great strides on the other side of the equation. Its proprietary FASST reactive transfer printing process has produced solar cells in a record setting six minutes, according to HelioVolt that's 10 to 100 times faster than current production of thin-film photovoltaics and could lead to manufacturing costs of less than $1 per watt.

September 6, 2007 Solar panel manufacturing is a costly process and is a major reason for solar electricity being so expensive to set up and maintain. In what it describes as a world first, Applied Materials has introduced an integrated production line for manufacturing solar modules using 5.7m² glass panels. The ultra-large substrates, sized at 2.2m x 2.6m ,are designed to achieve low production cost per watt and drive down the cost of solar electricity installations by around 20%. Read More
