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.

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).

I don’t know what it is about flashlights and kids. My daughter has every toy a 4-year-old could want and as is the way of the world, she would rather play with a box or my flashlight than all the toys in her room. That means that every time I need my flashlight I have to search her room for it and when I find it, the batteries are usually dead.

A new green flashlight called the Hybrid Solar Light uses solar cells to keep the battery charged. The battery is able to store energy for a claimed three years. Light output from Hybrid solar Light is not that strong at 40 lumens, but it will work in a blackout or to look under the couch for your remote. Water resistance to 80 feet is promised as well.

Helios was clearly inspired by the Jurassic era, when dinosaurs ruled the Earth. Helios is a concept design for an off-road electric solar-powered vehicle. When you take a break from your off-roading and stop the vehicle, the car will spread its “wings” which are made of photovolatic panels, in order to capture the sun’s rays and charge up the battery.

You’ve seen the concept in nature, where some animals have stretchable skin that absorb heat and light. A lizard might stop on a rock to take a breather and as he does, he opens up his extra skin and recharges. Same thing here. The Helios Concept won the Best Use of Technology at the Interior Motives Design Awards 2008. Pretty awesome.

This is one of a small fleet of GPS and cameraphone equipped bicycles that Flickr has deployed in select cities around the world. It’s purple, solar powered, pedal powered, GPS powered and it probably needs a little basket with a bow to complete the girl’s bike look. The bikes have handlebar-mounted cameraphones (Nokia N95s, based on the metadata in the Flickr photos) that will snap a shot every 60 seconds while the bike is in motion. Then the photos get uploaded with the geodata, to a special Flickr account.

I have no idea what the purpose is, other then publicity. I suppose they could partner with Nokia etc and start selling these bikes. They are likely to be a nice collectible in a few years, so if you have one keep it safe. And try not to get into too much trouble snapping pics of drug dealers and uploading them.

The Spark Lamp concept by Beverly Ng is an LED lamp that you can flip over during the day to recharge itself using solar power. It’s designed to educate the owner about their power consumption. The lamp sports integrated WiFi which wirelessly keeps track of you home’s power usage. When you turn the lamp on, it will change colors and flash to tell you what your home’s power consumption is.

It’s no accident that it looks like a houseplant as a metaphor for how plants are powered by sunlight through photosynthesis. The Spark Lamp was created in reaction to the Swedish’s government response to the energy crisis. In Sweden, future homes will have smart meters that will give real-time feedback to homeowners on the internet. But data on a website is not all that engaging so the Spark lamp was developed to enhance the experience.

Air conditioners are not usually solar powered because they use so much power you would need a large surface area of solar panels to keep it going. What’s interesting here is that the GreenCore 10200 solves this problem by using a battery pack that it recharges continuously throughout the day. (It can also be charged directly from the wall)

The GreenCore comes with a configuration that will not be enough power to run the air conditioner completely on it’s own, but what it will do is save you some serious money on your next power bill by doing it’s part and it can be combined with other solar panels to supply its complete power needs. The technology looks pretty promising and can be used in a variety of ways.

This one was conceived as a green and portable commuter transport. What we have here is a fold-up bike that runs on solar power obviously. The name says it all. Power is stored in a battery that you can use at night, and you can even power your other gadgets, like your iPod.

It looks kinda cool in bike form, but when you fold it up it resembles an alien egg that appears to be sending signals to it’s home world. In fact it’s not sending signals, but it’s pointed upward so that it can track the sun’s movements in order to maximize the power it’s sucking down. Even so, it’s still creepy. One day it might get it in it’s head that you belong in that egg so it will keep you there as it points toward the sun, warming you in your egg, so that you can hatch out as a new lifeform.

The iPhone 3G does a whole lot more than its predecessor, and that means that the battery is going to drain much faster. All of those cool new apps will also suck up the juice. The iPhone 3G Solar Charging Case will offer some protection for your iPhone 3G and also has a built-in solar panel that will collect the sun’s rays and turn them into electricity.

Power is stored in a 1,500mAh battery that will give your phone a full charge. Recharge time is about 3 hours. It may not be the most beautiful of iPhone cases, but it’s a good option for those who are thinking green with their gadgets. The price is $54, while the sun’s rays are free.

Buffalo introduced their new BSKBW01SB solar powered wireless keyboard. It features a small and adjustable solar panel just above the number pad so you can better capture the sun’s sweet nectar. Maybe there’s only one tiny ray hitting your cubicle, if you get the right angle, you have power baby!

It also runs on batteries just in case you live in Alaska. It’s got 17 hot keys, does it’s thing in the 2.4 Ghz frequency and will give you a range of 10 meters. The keyboard will go on sale in Japan by mid July at a price of $135. You may be saving power, but not money.
