Panasonic fuel cell
Panasonic's prototype fuel cell can run a notebook for up to 20 hours. If the notebook operates at 13 watts or less, which is about average, the fuel cell powers the notebook. If draws more power than that, a battery helps run it. Panasonic says it has no plans to commercialize this fuel cell device just yet--it wants to shrink its case to fit flush with the notebook case. A version of the fuel cell might hit the market in 2007 or so.
A prototype of a phone from Philips Semiconductor that switches automatically from cellular to Wi-Fi. Phones containing the chips will come out later this year, and with them, consumers can possibly cut their bills, said Philips Semi CEO Frans Van Houten.
