Logitech has unveiled the K750, a solar-powered wireless keyboard.

According to Pocket-lint, the keyboard features two solar panels and can be charged from either the Sun or an indoor lamp. Logitech says the solar panels on the 7mm thick keyboard will last for 15 years, and it's five times more energy efficient than other keyboards from the peripherals manufacturer.

The K750 uses Logitech's Unify wireless 2.4GHz system, which supports up to six devices at once, to connect to a PC. The company also claims internal batteries mean the keyboard can be used for up to three months in the dark.

"You don't always have light. You cannot have a keyboard that stops working," vice president of product marketing, Denis Pavillard, told Pocket-Lint.

A free desktop app that measures the energy left in the keyboard and the light level of the surroundings can be downloaded from Logitech's website. The keyboard's green credentials are further enhanced by the fact all of the packaging is recyclable.

The K750 will cost €79 and is currently available from Logitech's website. It will be made available on the high-street early next year, although Logitech has yet to reveal the UK pricing.
