According to new analysis from Juniper Research, consumer demand for environmentally sustainable mobile phone handsets could see shipments reach 485 million units by 2014.

According to their report, Green Mobile Handsets & Applications: Strategies, Scenarios & Forecasts 2009-2014, even with an incremental attitude shift by consumers, numbers will still grow from a quarter of million shipments in 2009 to over 105 million by 2014.

Paul Ridden Writes: Not only does the Fit-PC 2.0 make claims to be the world's smallest fully functioning PC but also to be the greenest. I can't remember seeing anything smaller (and I've seen a LOT of PCs) so that's one claim that I can't argue with. The PC is 115mm by 101mm by 27mm, so if you've seen anything smaller that provides the same or similar specs, feel free to leave a comment!

The humble radiator quietly and anonymously sits against the walls of numerous homes throughout the UK. When we're cold it gives us heat. It requires little if any attention, it just sits there and provides us with efficient warmth when we need it - right?

Well, sort of. There is a secretive side to this familiar beast that can be quite wasteful and costs us money - the side I'm talking about faces the wall. But thanks to a simple innovation that sits on top of the radiator all this wasted heat can be drawn back into the room to get you feeling all toasty much quicker and allow you to turn down that power hungry thermostat, saving you money!

Festival season is just around the corner and the good old UK weather might not be the only thing that stops you having a good time. But if you're a green gadget lover like me, then taking your favourite tech with you to the next music festival might be a cause for some concern...

Gadgets need power and being a greenie you naturally need to make sure all your cool tools are powered up without harming the earth. Mobile phone giant Orange has recognised this need for eco-power and is offering the Power Pump as the charging solution of choice: created by energy experts Got Wind, the Power Pump will rely on some nifty legwork to ensure your mobile phone will always be charged and ready for action - whether it be for snaps, video, MP3s if there's no-one you want to see or even to contact your friends.

It's been a while since green gadgets have hit the headlines, but they're back with an eco-friendly bang as Sony Ericsson announce the launch to two new green phones, to be out later this year. They've gone back to basics with the handsets and have steered clear of solar panels and associated malarkey, and opted instead for recycled materials and environment friendly materials.

You like the idea of getting a green charger for your MP3 player or mobile phone and solar sounds good - but you live in the UK so bright sunshine is not something you can rely on. What to do? A company called Kinesis Industries is about to launch a product that may just have the answer!

Not only does the Kinesis K3 charger soak up the sun (when it's available) but it also features its very own wind turbine. It's a very portable 78 x 236 x 8mm and has LED indicators on the side to let you know just how much sun or wind has been turned into energy.

Back in the autumn, we had a lot of fun testing out the latest in home energy-monitoring gadgets; discovering the ugly truth of how much electricity we consume. I was quite impressed by how easy it was to monitor the data on my PC, but now these devices have joined the social media generation and will actually tweet the information direct to your twitter account!

Tweet-a-Watt integrates with the Kill-a-Watt (one of the top-selling energy monitoring gadget's that's now available to buy in the UK here) to bring you your meter readings updates wirelessly, via twitter. You can see a live account of how it works here, and in all honesty, some of the reports are a damn sight more interesting than 90% of the 'tweets' I receive on a daily basis! [Via Adafruit]

Electrolux are set to launch the world's most eco-friendly vacuum cleaner this April in the UK, due to retail at £159.99. Called the Electrolux Ultra Silencer Green, part of what makes this vacuum so green is the fact that it is partly made out of shredded cars.

The body is made with 55% recycled PP, which saves two litres of crude oil and 80 litres of water per vacuum. As well as being made out of recycled materials it is also 90% recyclable itself. Comparing this new model with a vacuum made out of virgin plastics, there is a 90% reduction in energy consumption during manufacturing.

'Solar' really seems to be the buzzword in green tech at the moment, so I was interested to see that batteries are the latest electrical essential to get their own panels. 'Suncat' batteries (so-called because you charge them by leaving them to bask in the sun, like a sleepy cat) are still in embrionic form at the moment, and not available in the shops. But the good news is you can make your own, following instructions on DIY boff Knut Karlsen's blog.

You'll need to be able to source some photo voltaic cells to make your Suncats, but a quick glance at the tutorial suggests that's the hardest part of the job. [Via Treehugger, Shiny Shiny]

You may have heard the good news that cries of 'has anyone got a charger for a Nokia/Sony/Samsung?' etc will soon be a thing of the past, as the tech world has finally produced what seems to any non-geek to be the most obviously useful gadget ever: a charger that works on any phone.

But even better is the news that this super-charger will be greener, too. According to the Telegraph, the new universal chargers will consume half as much energy when on standby as today's charging cables, and will be supported by the majority of mobile phones by 2012.

Mobile phones companies are falling over themselves to get greener, and hot on the heels of Samsung's solar powered handset comes another model making use of daylight-powered technology: Chinese manufacturer ZTE has just released its Coral-200 Solar handset, billing itself as a saviour for emerging markets where electricity is scant, or not readily available.

Unlike the rather slick-looking Blue Earth, however, the Coral is a rather bog standard and decidedly old-fashioned looking candy bar design, with the solar panels on the rear. But again this is completely justified, as I can't imagine eco-friendly mobile owners wanting their phones to resemble and pack all the battery guzzling software and features that come hand in hand with a lot of the standard phones on offer these days (and if they do, they'll be waiting quite a while before that's even considered a possibility).

Understandably, news of a solar powered touchscreen phone from Samsung was met with high levels of scepticism. But it's not April Fools Day - it's not even close, so why was my initial reaction that someone is yanking our chain? I'll tell you why. It's because, let's face it, an energy efficient, solar powered touchscreen phone sounds just a little bit far fetched, don't you think?

But scepticism aside, it appears Samsung's eco friendly phones, dubbed Blue Earth, is real and being green is at the top of its agenda. For a start, they'll be no charging via an AC outlet for this bad boy, oh no. Just like the process of photosynthesis, this phone requires sunlight via the solar panels on the back. And apparently, it'll generate enough juice to call anytime anywhere - which is an ambiguous statement to say the least! Is this after only8 a few hours of sunlight exposure, or days?

If you're a car owner who spends the occasional painful moment contemplating your pride and joy's impact on the environment, then a new GPS system called Econav is being billed as a great way of assuaging your guilt. The idea behind it is that you're purchasing a premium looking satnav, equipped with the usual features such as GPS, gear change indicators, speed indicators and traffic alerts, but you're also getting their customised Econav technology built in.

And what does that mean exactly? Well the idea is that it will help save you money on fuel and cut your carbon emissions, and it does this by analyzing various route options and giving you an eco-related readout of the potential cost to yourself and the environment.

If you've ever shared space with someone with a hairdryer habit, you'll probably already be painfully aware of how much juice these things get through.They're notorious for over-heating and shorting out electricity circuits too, so if they could only invent one that wasn't so power-hungry that would be a good thing for all concerned.

Babyliss claim to have done just that with their new 'eco' hairdryer, which uses around half the electricity of a standard model. Most dryers use around 95 per cent energy for heat and 5 per cent for air flow, but this model uses a new type of motor that optimises air flow. In other words, it boosts the least energy-intensive way of drying your hair. £19.95 from Ethical Superstore

With comments such as 'sounds like a jumbo jet taking off' versus 'I'd never buy a regular kettle again', Hippyshopper readers were somewhat divided on the Tefal Quick cup: is it technically a kettle or not? Does it matter that the water doesn't actually boil? Never has a kitchen appliance stirred up so much passion.

But the Quick Cup certainly has its fans, and with its ability to produce a cup of Joe in three seconds flat, its energy-saving graces are not to be sniffed at. And now, you can get a smarter, more streamlined looking model for your eco kitchen.
