The KYE Systems SlimStar 820 Solargizer is a 2.4GHz wireless laser desktop mouse and keyboard with a twist. Instead of batteries, the keyboard, which was launched at CES 2007, has a small solar panel embedded just above the keypad for its power requirements.
The ergonomic mouse uses batteries and special power saving features to conserve energy usage. The keyboard has a USB cable charger and batteries should the sun set early, averting any potential power shortages.
The SlimStar 820 Solargizer has 17 function keys, an effective 10 meter range from the wireless USB dongle, adjustable DPI resolution for gaming, and several hard and soft power saving features. The keyboard will retail for $129 USD.
