Wireless keyboards are great for keeping your desk clutter-free. But no one wants to make a trip to the store for a fresh pack of Energizers when their keyboard dies.

Enter: Logitech’s Wireless Solar Keyboard K750, now available in a Mac-compatible model.

Essentially, it’s your high school calculator revisited. Solar cells lining the top of the unit use ambient light — desk lamps, fluorescent ceiling bulbs, and even sunlight for the old-school types — to charge the keyboard. Once set up, it runs without interruption so long as there’s at least some illumination. On a full charge, the K750 can run for three months in complete darkness.

The keyboard has the standard OS X layout with shortcut keys, and each key cap is slightly concave for pleasant typing patter. Choose either all black, or Apple white, with the option of three candy colors to accent the solar panels.

Along with eliminating all of that earth-killing battery waste, the K750 is made without PVC and arrives in a fully recyclable box. Mother Gaia would be proud of you.
