Bluetooth headsets is something you either love or loathe, and I believe that there is no real middle ground here. After all, you don't see people carrying a Bluetooth headset around but not using it, do you? While the higher end ones like the Aliph Jawbone are priced slightly out of the reach of most folks who are currently running a tight ship, it is nice to see that the mid-range market still has plenty of choices to choose from. By choices, I mean in terms of branding as there is very little to differentiate one from the other in terms of technology and design. The SolarVoice i908 Bluetooth headset takes a slightly different route as its name implies, and you can read more about it right after the jump.

Green technology has long been hailed to be the next big thing, and in a recent edition of the TIME magazine, it has singled out how California has been a hotbed for new and emerging technologies for a long time now, with green being the main theme way before the rest of the world caught on. Having said that, with more and more people carrying additional gadgets and gizmos with them wherever they go, making sure all of those will remain charged to the maximum can be quite a task, not to mention packing in their respective chargers into your suitcase whenever you want to head out of the country. Portable multi-device chargers are handy, but those themselves will need to remain juiced up as well in order to function at its best. Enter i.Tech's SolarCharger 906, where it not only holds a 1,260mAh capacity, but comes with a decently sized solar panel on one side to absorb the sun's rays, transforming it into electricity which is stored in the internal battery for future use.

Check out the new range of solar bags from Mascotte Industrial Associates of Hong Kong, where it will rely on DSSC (Dye-Sensitized Solar Cells) technology to make sure that your bag is able to store converted solar power in its internal battery so that you can later juice up thirsty gadgets at your very own time. Our own experience tells us that such solar panels aren't exactly that effective, and you'd do best with a power outlet nearby. Still, some sunlight is always better than none, right?

The Sun Drive keychain is very different from most other keychains since this model sports a USB solar charger that allows you to juice up a range of USB-powered devices on-the-go. Even though it is small in size, it is still able to offer up to 35 hours of juice for most portable devices, or roughly the equivalent of 100 minutes of talk time on your cellphone. Apart from that, it can carry vital information within thanks to a choice of 2GB, 4GB, 8GB and 16GB capacity within. Prices start from a surprisingly affordable $23 a pop.

The recent World Solar Challenge saw the Japanese team emerge as winners, upsetting the pecking order that was once dominated by 4-time Dutch champs. They took top spot by making it past the finish line of the 1,864-mile solar car race that was held across Australia, completing the gruelling journey in 29 hours and 49 minutes even on a flat tire, giving it an impressive average speed of around 63mph.

Solar seems to be as much the in thing these days as with multitouch displays, and the Neuber Energy Sun Bag carries just one of those. It will feature a huge solar cell on the front flap which will help soak up the sun's rays during the day and turn it into something useful, making it capable of juicing up tiny handheld devices of up to 5 volts. Perfect for customization buffs, the Neuber Energy Sun-Bag will have a choice of 37 colors in addition to optional custom printing. It has been priced at $150 with no word on availability just yet.

iPod docks are dime a dozen, but how many of them are actually green and good for the environment? The Reverb solar-powered iPod dock from Regen is one of them, where it is capable of offering up to a dozen hours of continuous playback on a full charge. Charging is much slower compared to plugging it into a power outlet of course, where it will take 20 hours of outdoor sun to hit a full charge while indoor sun will take up double the length of time. For those who crank up the volume on a frequent basis, the Reverb will last for a mere 4.5 hours. Features include a stylish 35" iPod tower, a backlit LCD display and an integrated photovoltaic panel. It won't come cheap though, retailing for $2,299 but at least after the apocalypse, you can still tune in to your iPod when there is no power supplied through the grid.

Mitsubishi Chemical will harness the power of the sun by using solar cells to power its air conditioning system in trucks so that fuel consumption and carbon dioxide emissions can be reduced in an effort to keep the earth as green as possible for our next generation. This 10-ton prototype truck will come with two types of solar cells which allows it to achieve a maximum output of 900 watts. Its storage battery enables it to see action regardless of whether it is rainy or cloudy, and calculations have shown that should all of the 1.4 million existing trucks in Japan were replaced by this model, CO2 emissions might eventually be reduced by 1.65 million tons per year!

Sharp Japan recently announced that they managed to roll out a solar cell that will boast the world’s highest conversion efficiency of 35.8% which is a marked improvement over its predecessor that touched just 31.5%. This model is a compound solar cell, where at least two elements form photo-absorption layers to help achieve that magical number. Meant for use on space satellites and numerous special equipment, Sharp aims to commercialize this triple-junction compound solar cell within 3 years' time. Good luck, guys!

The Zegna Ecotech Solar Jacket is a long time in coming - after all, who doesn't want to wear a stylish jacket that not only keeps the chills out, it is also capable of absorbing the sun's rays and turn it into electricity to juice up your many gadgets that tend to travel with you? Made from recycled plastic for that added touch of green, you will find solar panels dotting the upper sleeves. Bear in mind these solar panels can be detached for easy cleaning and making you look more normal.

Check out the reNEW Solar Battery Charger concept that does come across as some sort of decorative frame which hangs out on your window through the use of a suction cup, where it will sit pretty on any table. When you take a closer look at it, you will realize that this is a solar charger for rechargeable batteries, so hopefully neat designs such as these will help move more people's hearts and wallets to lean towards the green side of things. All you need to do is slide batteries down the back of the frame straight into the protective charging pouch and you're good to go. Too bad this is but a concept at this point in time.

Vienna-based design studio Vandasye has come up with a solar-powered clock prototype that well, basically tells the current time at a glance, being powered by solar energy - guess there is no need to change that pesky AA battery once every year or so, eh? Not too sure just how many batteries this will save in the long run, but it is nice to see solar powered devices gaining traction in mainstream consciousness.

LG has unveiled an e-book reader that boasts a solar cell to help it stay juiced up whenever possible, with the solar cell measuring 10cm in width and length to fit the 6" display e-book. Measuring 0.7mm in thickness while tipping the scales at 20 grams, the solar cell is thinner than a credit card while weighing like a fountain pen. Currently, the energy conversion efficiency rate of this product stands at around 9.6% - making exposure to sunlight for around four to five hours garnering another day's worth of running time for the battery without having to have it go through additional charging.
