Evolta climbs Grand Canyon -- On May 24, a 17-centimeter tall, 130-gram Panasonic Evolta battery mascot robot scaled a 500-meter cliff at the Grand Canyon in a publicity stunt to showcase the endurance of the Evolta AA alkaline battery, which the Guinness Book of World Records recently recognized as the longest-lasting of its kind. Powered by a pair of Evoltas, the robot hoisted itself up a 530-meter length of rope suspended next to the cliff, reaching the top after a grueling 6 hours and 45 minutes.
