Since I literally just changed the batteries on my own wireless keyboard earlier this week, it occurred to me that more of you might want to know about the Logitech Wireless Solar Keyboard K750, which was introduced late in 2010.

Retail-priced at just under $80, the keyboard uses solar power -- actually any form of light -- to keep itself charged up. The company said that it can go for up to three months in darkness without being charged. A solar app provides the information you need about charge levels and such.

The keyboard is about one-third inch thick, and it is made out of PVC-free materials, further enhancing its green technology credentials. It includes 2.4 gigahertz wireless, along with 128-bit AES encryption, as well as a unifying receiver that you can use to connect up to six Logitech mice or keyboards. Another thing to note: the product carries a three-year hardware warranty.

Sadly, if you are Macintosh user like me, you're out of luck: The keyboard requires either Windows Vista or Windows 7.

  • Cool.

    I use a wireless keyboard and they are very thrifty with batteries, but who wouldn't want a keyboard that you *never* need to worry about batteries at all?

    Besides, this falls into real "magic" territory. The keyboard just works. I assume the rechargeable batteries will fail over time, but by the time they do you'll probably want a new keyboard anyway...

    Very very cool.

    This is very cool, but as a gamer I need a wired system for the most precision and lag free experience. G9x mouse + G19 Keyboard are the way to go baby. But this is a seriously cool KB.

      @Bates_ Unless you're playing games that require Just Frame input to be effective (and are actually good enough to pull it off), you'll be fine with a wireless keyboard/mouse. Granted those G series mice and keyboards have way more gaming advantages than a simply wired connection.

      I have one of these. It works very well for games. Indeed, I'm really startled at how well it works, in general.

      For gaming, there is no inherent reason why wired is better than wireless. The PC Bios polls the keyboard and mouse buffers anyway -- whether it does that by wired or wireless means is irrelevant because it is the polling rate that matters.

      Traditionally, wireless keyboards and mice had lower polling rates, probably to lower battery use. Moreover, the signals themselves take a little processing, and slower CPU's would take longer to do that.

      There may still be slight differences, but they are going away rapidly as newer tech permits higher polling rates and faster processing.

    Only thing that would make it better is a matching mouse that was solar and/or a usb plug to use it a solar charger for other devices when you are not typing on it.
