Glowing walls made from graphene will make lamps redundant
Saturday, February 6th, 2010
Forget those compact fluorescent bulbs, or even fancy LED lighting. Scientists in Sweden and the USA say they have developed lighting panels using the wonder material graphene, which one day could make the basic lamp redundant.
The material can be fashioned into large energy efficient flexible sheets called LECs (light emitting electromechanical cells) that can cover an entire wall or ceiling, filling the room with an adjustable and even source of light. We've seen how OLED technology promises a similar approach to lighting, but the scientists say the graphene panels are much cheaper to produce, and don't contain the metal alloy indium tin oxide that makes OLED panels tricky to recycle.
No word on how long we'll need to wait before you can buy LEC panels at your local hardware store.

Back in September last year, Sunnyvale, California-based Advanced Micro Devices did what most of the industry was already prepared for, namely the introduction of its first series of graphics processing units with support for DirectX 11. The chip maker did so by announcing their fastest cards yet, the Radeon HD 5800 series, which als... (read more)
Some of the most interesting products we came across during our short visit at Sony's booth from IFA 2009 were the MDR-NC300D noise canceling earphones, recently released by the Japanese company (well, at least they were pretty recent at the time of our visit), which really managed to draw our attention for two reas...
