Sony unveils hand-powered digital camera

clipped from www.brisbanetimes.com.au Sony has unveiled a prototype digital camera shaped like a pizza cutter with a wheel that can be turned to generate enough power to take pictures. The "Twirl N' Take" camera generates enough electricity for one snap if the the wheel is moved for some 15 seconds, according to a Sony official. A digital camera similar to those used in mobile phones is installed in a handle attached to the wheel, which is equipped with a power-generating device, she said. Moving the wheel and taking pictures would appeal to children but the company has no immediate plan to commercialise it, she said. As the camera has no screen monitor, users must connect the device to a computer to see their pictures. The camera is the latest addition to Sony's "odo" line of hand-powered prototypes aimed at raising environmental awareness.
