"ENERGY: Technology cutting final land-line links"
What with the Bluetooth headset crowd wandering the streets talking to the air, you might have thought the final tether to land lines had already been cut. You would be wrong. At least two vital functions have yet to be loosed: network routers, which must always be on and thus cannot be battery-powered, and the chargers for all those batteries powering the world's wireless network nodes, cell phones and laptops. Now developers and researchers are getting out the wire cutters. With half a dozen companies already touting battery-powered mesh networks as replacements for dedicated, wired routers in industrial and field environments, observers predict the technology will work its way into the mainstream. And researchers at the Massachusetts Institute of Technology are perfecting a technology that they say could recharge batteries wirelessly--and perhaps eliminate batteries altogether--by harnessing omnidirectional wireless power beacons
