The problem with wireless keyboards is that the batteries eventually go flat, but Logitech has announced a new model that charges itself using solar energy.
Available from January, the Logitech Wireless Solar Keyboard K750 has integrated solar panels to charge its batteries whenever there is light available.
The device charges up even from artificial light sources such as lamps, and stays charged for at least three months even in total darkness, according to the firm.
"The keyboard is still the best input device for typing emails and IMs, updating your Facebook page or posting responses to your favourite blogs, and the Logitech K750 is the next big innovation in keyboard technology," said Logitech vice president of product marketing Denis Pavillard.
Logitech also plans to release a free-to-download Solar App that shows how much charge is left in the batteries, and whether the keyboard is receiving a sufficient amount of light for charging.
The keyboard uses Logitech's Unifying receiver, a tiny USB wireless module that fits into a USB port of a laptop or desktop and is small and discreet enough to be left connected at all times, according to the firm.
The Unifying receiver is common across many Logitech wireless keyboards and mice, and each module supports up to six devices.
The Logitech Wireless Solar Keyboard K750 is expected to cost £69.99 and is compatible with PCs running Windows XP, Windows Vista and Windows 7.
