Legit Reviews posted a review on the Logitech K750 Wireless Solar Keyboard

Going green is the thing to do these days. Not only does it save space, it saves the environment. Logitech is at the forefront of this push for a greener world with the release of their new Solar Keyboard the K750 Wireless Solar Keyboard. Yes, you heard right - solar. As in, no more batteries.

Quote: "With a lot of companies these days finding themselves with the task of making their businesses a lot "Greener," naturally Logitech would be one of those companies that would be at the forefront. So, why not design and produce a "Green" keyboard? Well Logitech has, but they have gone way above and beyond the usual recycled packaging, or the recycled paper used for the user manual. All of what I have just mentioned has been done; as a matter of fact, there isn't even a user manual as they have just gone ahead and printed the user manual on the inside of the box that the keyboard comes in. But if that doesn't impress you, then what I am about to say should. Oh yes, my friends; they have eliminated the need for batteries. Logitech has designed and manufactured the K750 Wireless SOLAR Keyboard (PN 920-002912). Gone are the days of buying and replacing batteries in your wireless keyboard. Also gone are a lot of the used batteries that end up in our landfills. The Logitech K750 Wireless Solar Keyboard is the first solar powered keyboard on the market today...
