While you do want your GPS available whenever you want it, ultimately you don't want it that often. Not only that, but parts of it are able to rest even when you do want it. So it's only logical that a Solar Powered GPS should come out. Sporting a 26 hour battery life from full charge, naturally it's recharging itself somewhere from eight to twelve hours a day. Accurate to within 3.8 meters and sporting Bluetooth, at only 105g you can take it anywhere (even places it can't take you). [GT]
