With modern devices consuming less and less power and the efficiency of solar cells increasing, it was only a matter of time before the Solar Powered Keyboard made it’s way into consumer’s hands. And here it is. Logitech has just introduced the K750 Wireless Solar Powered Keyboard. This thin keyboard requires no batteries and can last up to 3 months on a single charge. Great for your mancave marathon WoW winter hibernation session. The two solar panels at the top can be powered with even indoors, so you don’t have to sit poolside to use this (although you certainly could, why not?). Logitech includes a downloadable solar app that lets you measure the light levels and determine if you need to charge up your keyboard. The K750 sells for about $80 direct from Logitech.
