4 green tech gadgets you should consider buying

We could all be a little greener in our lives. For one thing, going green often saves you money (in the long run, if not the short), and of course, it helps protect the environment. While generally speaking the tech world might be obsessed with power and performance, these days energy efficiency and green credentials are definitely a consideration for many.

So we thought we’d round up four neat green tech gadgets you might not be aware of – one a keyboard, one a mouse, and a couple of other novel inventions which could make your computer study a better place.

Plastic keyboards will one day fill the Earth, but the iZen keyboard won't be among them. The original eco-friendly Bluetooth keyboard, the iZen is handmade out of 92 per cent bamboo. It's renewable, recyclable, and portable, making it a great option for iPad users on the go. The iZen keyboard is wireless and works with any Bluetooth-enabled device – not just the iPad. It has a rechargeable lithium-ion battery and charges with a USB 2.0 cable. The bamboo is coated with wax, which protects it from absorbing water and the oils from your fingers. And it looks very different, and very cool (see the image at the top of this article).

Taking a socially conscious spin on tech, LittleSun aims to improve the quality of life of those who don't have direct access to electricity. Many of these people rely on fuels like kerosene to light their homes.

The LittleSun solar-powered lantern is made up of a 60mm x 60mm single cell mono-crystalline solar module that needs four hours of sunlight to supply five hours of LED light. The lantern provides 10 times more light at one-tenth of the cost of the average wick-based lantern. It's also very versatile and safer than a flame; it can be hung on the wall or from the ceiling, placed on a desk, affixed to a bicycle, or even attached to clothing.

It's also dustproof, plus it’s water, UV, and heat-resistant.

This clever little power plug extension strip (with 7 plugs) will sense when you switch your PC off, and automatically turn off the other peripherals connected to your machine such as speakers, monitor, printer and so forth. Or it can save you energy in the living room, and turn off all your other AV gear when you switch the TV off. Clever, eh? And it’s surge protected, too.

Wireless computer mice are great, but their dead batteries take a toll on the Earth. Fortunately, we have the Genius DX-Eco, a wireless battery-free mouse. The DX-Eco's electric double-layer ultracapacitor requires a quick three-minute charge each day and will last up to 100,000 charges. The mouse has a bidirectional 2.4GHz connection, allowing you to work about 50 feet away from your computer. It also operates on a variety of surfaces, including dusted glass, marble, carpet, and even a sofa.
