We’re not looking at keyboards every day but every once in a while we find something interesting. Here’s a keyboard from Japan. Not only is it wireless but it’s also powered by light. Just above the numeric keypad there’s an adjustable solar panel. Simply move it around to make the most of your light source. It will power up your keyboard immediately replacing those usual batteries. Sure you can run it on batteries too, but why not use the Sun’s energy instead?

Besides the regular keys you get a bunch of hotkeys for media and Internet applications. Now you will be able to simply write your emails and documents on this wireless keyboard while using the light in the room to charge it.

This 2.4GHz wireless device is available for $120. A good price since you will be saving quite a lot on batteries from now on. Just make sure you’re not working in the shadows.
