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.

Paul Liao, chief technology officer of Panasonic North America, shows off the company's flash-memory camcorder. The 2MB of flash built into the camera can take about 40 minutes of video. Price is about $1,199. The Japanese giant, a minor player in cameras in North America now, will make a big push in the U.S. this year. A big selling point, says Liao, will be the camera's image stabilization, designed to greatly reduce image jitter. The camera weighs about 7 ounces.
