Solar-powered gadgets are nothing new. But a solar powered home theater system? It’s appropriately named the “Guiltless Green Home Theater” and was manufactured from scratch by Home Theater Specialists of America (HTSA). It’s the first of its kind and has some surprising specs.

For one thing it will give you up to 19 hours of video and audio playback even if the sun isn’t shining that day. They didn’t sacrifice quality either, with a Sharp projector, a 100″ Stewart Filmscreen, six SpeakerCraft in-wall speakers, an Integra AV receiver, Monster Cable wiring, Lutron lighting, and Universal Remote Control.

Scosche just launched a new solar powered gadget in the Solchat Bluetooth Speaker Phone. It’s designed to be used in your car, and features a built in lithium ion rechargeable battery and a solar panel so you can charge it up it in your car’s windshield.

In addition to being able to be charged by the suns rays, it also can be recharged via USB or via a car adaptor. It’s available now for $99.99.

We could probably all stand to get a little greener in our everyday lives. Portable and compact solar panels like these make it pretty easy, since large panels are expensive and not suited for the home. These are especially great for apartment dwellers looking to get greener.

Veranda Solar is working on these solar panels that would sunbath outside of apartment windows, gathering rays that will power your stuff inside. No word yet on how much power you can expect to get from them, but the price is estimated to be from $400 to $600.

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.

A few days ago we introduced you to Samsung’s Blue Earth, their solar powered touchscreen phone. Well, if you like your mobile phones eco-friendly, here’s another choice.

The ZTE Coral 200 Eco Phone is from Digicel, a Jamaican Mobile Carrier. It’s an entry level candy-bar style phone with a solar panel on the back which charges the phone up when the battery gets low. There aren’t a lot of features, but it does have a color display. It should be available by June of this year.

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.

Samsung’s upcoming Blue Earth smartphone is a little different. In front you’ll find a touch screen, while the entire back takes advantage of the space with a solar panel. If you can believe Samsung, they are claiming that the panel produces enough electricity to place a call any time you need to.

We’ll believe that one when we see it, but as far as eco-phones go, this one is interesting. Keeping energy in mind, the phone includes an Eco Mode, which adjusts screen brightness and deactivates Bluetooth. Not only that, but most of the phone is made from recycled water bottles. Both the handset, and it’s charger are free from harmful substances.

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.

Here’s a concept that not only makes your back yard look all high tech, but it will also harness the sun’s rays to power your life. The Solar Tree offers a realistic solution to existing structures. Even a small backyard will have room for one of these. It provides it’s own shade, so that’s a plus on a hot day.

While you are staying cool beneath, the swing-out panels are absorbing the sun’s energy and converting it into electricity that you can use. When night comes, just fold it back. It even has you covered if you decide to move as it’s easy to bring it with you.

Whether you live the life of James Bond or Lara Croft, you may occasionally find yourself underwater, scuba diving. From Swiss company Uemis comes this computer with colored OLED display. The Uemis Zurich diver assistant supports 10.000:1 contrast ratio in a colored display, has intuitive menu control, and 5-way navigation with three non-slip slide controls.

The scuba driver assistant can be connected to a PC via USB and the myUemis can also be synchronized in a similar manner. It also has a tank pressure sensor which transmits the tank pressure to the SDA uemis Zurich. The wristbands are available in three different sizes, in case you have an odd wrist.

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.

One thing that Bluetooth handsfree kits have in common is that you need to replace batteries or charge them. That can be tedious, especially if you live in a state where hands free kits are required and yours goes dead while driving.

A company called Iqua has a new Bluetooth handsfree kit that promises to provide unlimited talk time called the Iqua VizorSUN. The device gets power from a solar panel on the back of the gadget. In optimal light conditions, the maker says it will work indefinitely.

The Float-a-Pet collar is a good idea. For one thing it keeps your pet safe, for another it’s fun to see pet heads floating down Main Street during a flood. Win/win. It’s an inflating floating emergency collar with a flashing light so you can locate your pet even in the dark.

Sure, dogs can swim, but that doesn’t mean they don’t get tired, just like us. It may not be such a great idea that the flashing light is powered by solar. Probably not the best way to power something that is made for emergency nighttime situations. But with this thing, at least your pet has a chance to become one of many floating heads in a flood situation.

An iPhone with integrated solar cells may be quite a ways off, so in the meantime Solar Arcadia’s solar-powered cases are your best option. The cases are available in SideFlip and Leather Flip models and offer a bit of extra protection for your handset.

They feature a solar panel so that your phone can enjoy at least a few more minutes of life while you’re out in the sunlight. Each case is constructed from ABS sheepskin and comes in a trio of colors. Red, white or black (The Leather Flip is only available in black).
