Wireless keyboard has solar cells for charging

Wireless peripherals are nothing new, but Logitech has done something novel by introducing one that charges itself. The Wireless Solar Keyboard K750 has an array of solar cells that juices up the internal battery. These cells are capable of charging the unit under normal indoor lighting—no sunlight required. If you happen to be stranded in the dark, the K750 is said to last up to three months on a full charge.

The keyboard itself is a laptop-style unit that measures just a third of an inch thick. Logitech doesn't say what sort of mechanism backs the chiclet keys, but the caps look nicely contoured. Thankfully, the key caps don't appear to be saddled with the same glossy finish as the rest of the keyboard.

Wireless connectivity is handled by a 2.4GHz radio, and signals are encrypted with a 128-bit AES algorithm to prevent snoopers from logging your passwords and other sensitive information. Bluetooth would've been nice, although support is hardly widespread in modern desktops, which have no shortage of USB ports for a wireless receiver. The K750 is set to appear on store shelves this month with a suggested retail price of $80.

Tip: You can use the A/Z keys to walk threads.
