Buffalo Japan will soon be launching their solar-powered keyboard, the BSKBW01SB. Given that wireless keyboards can eat quite a few batteries in their lifetime, it saves on batteries going to landfill as well as some small energy costs. The solar panel is in the top right of the keyboard, and can be adjusted to any angle to get the optimal light from your environment.
The keyboard operates on a standard 2.4GHz frequency and has a range of up to 10 metres. The keyboard also features 17 hotkeys, so it might be useful to use with a media center pc. Initial release of this green gadget is in Japan for 13,775 Yen ($135), but I expect we’ll see it in the UK and US within a few months.
