Sure, there are plenty of solar powered chargers to charge your gadgets, but few are as sexy or as versatile as the forthcoming Regen ReNu. The solar panel is used along with one of several optional bases. These include an iPod/iPhone dock, a sound dock with it’s own speakers, and an LED desk lamp.

The built in battery constantly stores juice even when your iPod isn’t docked, so that the ReNu can then transfer the charge into your device. It can even pull power from a wall socket if you don’t have light in your space.

Safaricom out of Kenya has rolled out its latest solar-powered cellphone dubbed the Simu ya Solar. The handset was constructed using recycled materials, while an integrated solar panel makes sure that your phone always have some spare juice.

This one is great for users who are in rural areas where electricity is hard to find and sunlight is plentiful. Another benefit for those users is that even if they do have access to electricity, they will save money by letting the sun do it’s thing rather than charging it and wasting resources.

The ideal phone would never have to be plugged in or at least would need to be plugged in only rarely. The reality today is that high-end devices like the iPhone burn lots of battery power and require almost daily charging to remain usable.

A company called MotionTouch has announced a new charger for the iPhone that is eco-friendly and charges by light. The device has a solar cell on the back of the sleeve that can gather power from some ambient lighting and from the sun.

If you enjoy carrying your speakers around with you, check out these Devotec Solar Sound Bluetooth Speakers. They come with a pair of 2W drivers, Bluetooth and AVRCP support, along with a 3.5mm jack and a 1,500mAh battery that should provide up to 8 hours on a single charge.

Don’t worry, you won’t be a complete slave to the sun. If you choose not to invest the 12 to 24 hours it will take to charge via solar, you can power it up via USB for 4 hours or so.

Solar powered e-ink displays are finally here. Neoluxiim recently showed them off for use in point-of-sale advertising. So all of your future e-ink ads will be in color for a more rich impulse purchase to be made by you.

While all ads are annoying, it’s nice to know that those energy-wasting flatscreen kiosks are on the way out. In the future you’ll still be annoyed by the ads, but you can at least rest assured that they will be greener.

Batteries? The Mobile Script Phone doesn’t need no stinkin’ batteries. It’s a concept device that features Internet browsing, working on-the-go, games and communications. All the stuff you already enjoy, just better. Plus no batteries.

The device has a few touchscreen displays, one in the standard format, the other is a flexible OLED display that can stiffen when a low voltage charge goes through it, to give you added viewing area.

Here’s a unique 4-port USB hub with the ability to juice up almost any compatible USB device. It even comes with a whole bunch of USB connectors to handle virtually anything you throw at it. Having a solar powered USB hub is awesome because you won’t add a single cent to your power bill thanks to that solar panel in the middle.

On cloudy days you can always hook it up to your car’s cigarette lighter outlet as an alternative power source. Only $20 and it’s a useful device. It’s like the K3 generator, without a windmill.

Samsung has announced it’s first solar powered GSM cellphone, the Crest E1107. It’s for eco-friendly, budget conscious types who want to harness the power of the sun. Supposedly, the Crest can generate enough power for 5-10 minutes of talk time with one hour of sun exposure.

I don’t know about you, but I associate the name Crest with toothpaste, so I’m a tad disappointed that this thing can’t power your spin-brush too. It has some basic additional features like an FM radio, MP3 ringers, fake call feature to avoid unwanted calls. Even a flashlight. Yet nothing to brush your teeth.

This 6 in 1 solar kit can be built into a dog, boat, car, plane (static and moving), and even a windmill. Looks like a great way to learn a bit about robotics and solar energy. Only £13.00, which is odd because I don’t think they get much sun in the UK, so not very much play time with this thing.

Still, rain or shine, you get a bunch of variety in one kit. Six robots are better than one. Buy a few kits and soon you’ll have a solar robot army.

This pair of headphones is clearly from the future. No doubt sent here to protect young John Connor’s ears and keep him listening to his tunes in style, so that he can one day be a kick-ass leader. At least, that’s what I’m guessing judging by how awesome they look. This is the Q-Sound headphone concept from Shepeleff Stephen and the design is simply amazing.

It looks great and also uses solar technology. That’s a solar panel running across the headband, where it will always catch the sun. The Q-Sound, being a concept, would also take calls or plug into a 3.5mm jack if you need it to.

Sometimes you can’t see where you are going, while driving. This might be due to alcohol, snow or even fog. Most likely alcohol. These Solar Driveway Markers sure would come in handy so you don’t end up parking in your living room.

They’re 1 meter tall, stick into the ground and are recharged by the sun so that they may blink red for 8 hours. That way when you come home you’ll know where or where not to park. Buy a whole bunch and put on a light show, or use it to actually confuse people, then sit back and watch the comedy.

Want some batteries that you can put out in the sun and power up? Knut Karlsen constructed his very own solar rechargeable batteries that soak up the sun’s rays and convert them into power. If you want to try your hand at making some, he has documented the DIY project to create the prototype SunCat battery. If you can get your hands on some flexible solar cells.

Knut has some connections at the Institute for Energy Technology, so it wasn’t a problem for him. Basically Knut attached the solar cells to old rechargeable NiMH batteries and used contacts from an old camera to connect the negative pole to the photo voltaic cells. And just like that you have batteries that can sit out in the sun and store up energy.

Can’t seem to get enough sun for your gadgets? If only that great big fiery ball in the sky would stay still. It would make it so much easier for you to harness those rays. That ain’t gonna happen, but here’s the next best thing.

The Solar ChumAlong solar tracking system is a solar charging panel that automatically tracks the sun just like those expensive arrays you see in movies. But this one is portable and lightweight, so you can always have power. The solar panel is always facing the sun so you’ll always be able to juice up your gadgets.

Numbers are an enemy to all. They force us to do endless calculations throughout our daily lives, and miscalculations. Numbers are everywhere. You can’t avoid them. By the time you have begun counting, they have already won. Because there will always a higher number then you can count.

Calculators are our only hope of staying sane as we constantly wage war with math. This one is slim yet stylish and solar-powered. And Credit Card sized. Having one the size and shape of a standard credit card will go a long way in helping you sort out this mathematical universe. No more miscalculating! Only $6.

Energizer’s Solar Recharger looks like an odd device. It looks like it could be an iPod battery extender, a AA charger or even a Solar adapter. And it actually is all of the above. Mainly, it’s a battery charger for standard rechargeable AA and AAA batteries and is primarily powered by an AC jack that’s assisted by a flip-out solar panel. The USB port can power your connected gadget and the Solar Charger will act as an extended battery for almost any USB-powered device, like your iPod for instance.

The beauty of this device is that through the use of cheap rechargeable batteries, Energizer sell it for just $50, with 2 AAs included. Some other features include weatherproofing and a rotating solar panel.
