  Clothing that could power your iPod - Telegraph 

  http://www.telegraph.co.uk/earth/main.jhtml?view=DETAILS&grid=&xml=/earth/2008/02/13/scipower113.xml

  The ultimate in power dressing has been devised by scientists: fibres built using nanotechnology that can generate electricity when they are twisted, bent and moved. Knee-brace gizmo to generate electricity ... Self-cleaning wool and silk developed using nanotechnology Fabrics woven from the power-packing fibres could convert fleeting movements of tents, curtains and clothes into electricity and follow in the footsteps of other energy scavenging devices coupled to the movement of the knee and to footsteps, heartbeats, and breezes. The American team that created the fabrics estimates that a square metre of material made this way could theoretically generate up to 80 thousandths of a watt, potentially enough to power personal electronics, from an MP3 player to a GPS. Developed by Prof. Zhong Lin Wang of Georgia Tech in Atlanta, the fibres are coated with zinc oxide "nanowires" - which look like brushes at a level of around a nanometre (billionth of a metre) - that generate electricity by the   [More...] [Less...]

  Broadband: Wired or wireless for the enterprise? 

  http://www.computerweekly.com/Articles/2007/11/27/228319/broadband-wired-or-wireless-for-the-enterprise.htm

  Author: Steve Broadhead Posted: 14:02 27 Nov 2007 Weighing up the benefits of alternative broadband infrastructures There has been much written over the past few years about broadband technologies. Whether ... wired or wireless, there never seems to be a lack of noise coming from would-be world-changing suppliers when it comes to broadband technology delivery. On the wired front we had the copper versus fibre argument. Fibre can do the job but it is still very expensive. Copper moved from just ADSL to Metro Ethernet (which became Carrier Ethernet) and suddenly running multi-megabit connections into offices over copper is not an issue. At the same time, the wireless brigade moved out of the local area network and away from all the proprietary (and often bizarre) mobile wireless technologies used by the likes of the emergency services and announced technologies such as Wimax on the extended wireless Lan, and 3G (and beyond) for mobile. And now we have talk of convergence between Wimax and mo   [More...] [Less...]
