One of my favorite tech toys growing up was my solar powered Casio calculator. Remember writing somewhat cryptic upside alphanumeric messages to classmates? Well, even if you're too young to remember antiquated "mobile" tech like solar calculators, you may appreciate this distant cousin, the Logitech Wireless Solar Keyboard K760, designed to work wirelessly with your computer, over to your tablet, and even with your smartphone...
Similar in size to Apple's compact wireless keyboard, Logitech's Wireless Solar Keyboard K760 adds just a little more height to accomodate for an array of solar panels much like my beloved memory of jr. high calculation devices. This is great for anyone who would like to forgo the continual battery replacement schedule inherent with wireless battery powered peripherals.
And unlike some of Logitech's accessories, the Bluetooth enabled Wireless Solar Keyboard K760 was designed specifically to work with OS X and iOS devices (being Bluetooth, it should work fine with Windows machines and Android devices too): Command, Brightness, Volume and Eject keys are included matching Apple's usual graphic design language.
Logitech advertises the K760 can charge using lamp light or natural light, and once fully charged, the keyboard won't need to bask in any light for another 3 months. Impressive!
Currently available for preorder for $79.99.
