In a promotional stunt, Panasonic attached a little robot to a rope and had it climb the rope…up the Grand Canyon wall.
Robot Evolta kept climbing and climbing — up a rope dangling from the cliff for nearly seven hours on a pair of AA batteries that Panasonic is billing as the world’s longest lasting. The vertical climb was 1,740 ft (about 500-metera) and took exactly 6 hours 40 minutes.
Guinness World Records certified Evolta earlier in the year as “the longest-lasting AA alkaline battery cell,” based on testing under guidelines set by the industry’s International Electrotechnical Commission this year.
Yeah, I think climbing the Grand Canyon or some very tall structure makes for a great measure of power available from a battery and that it can keep going and going and going…I’d love to see some competition like this between Duracell, Energizer and Panasonic; how cool would that be?
