Solar panels light up Yosemite National Park, don't spoil your view
Normally we like to keep our technology and nature reasonably separate, but like peanut butter and chocolate, some combinations turn out better than you'd think. In the latest in a long line of projects funded by the American Recovery and Reinvestment Act, Yosemite National Park has installed over 2,800 solar panels in the El Portal maintenance complex, neatly hidden from the all seeing eyes of the public. The plenitude of photovoltaic plates will produce about 800,000 kWh per year, saving the park $50,000 annually on its power bill and scoring it $700,000 in rebates from PG&E over the next 5 years. The 5.8 million dollar system cuts the park's reliance on carbon fuels by 12 percent, and is now the largest grid-connected solar energy system in the National Park Service. Press release junkies can hit the break for the official announcement; solar fanatics looking for a better view should check out KCRA's coverage in the links below.
Inhabitat's Week in Green: IKEA's massive solar array, climate-controlled clothing and ultra-green yachts
The summer sun supercharged green technology this week as Inhabitat reported that IKEA flipped the switch on a massive 65,000 square foot solar array and designer Markus Kayser unveiled an awesome self-sufficient solar-powered laser cutter. We also spotted a clever off-grid Tropicana billboard that is juiced by oranges, and we learned about a new piezoelectric film that could lead to laptops powered by typing. Energy-generating architecture also made headlines as SMIT announced plans to roll out their Solar Ivy system on several buildings and one designer unveiled plans for a green energy island large enough to power Copenhagen. Green transportation also reached for the sky this week as the sun-powered Solar Impulse airplane made its public debut at the Paris Air Show and EADS unveiled plans for an innovative all-electric commercial aircraft. Efficient autos also hit the streets as the Nissan Leaf became the first electric car to tackle Pike's Peak, and we learned that Porsche is working on a new breed of cars that are able to drive themselves. If pedal-powered transportation is more your speed you won't want to miss this beautiful kinetic energy-storing Potenza vehicle, and we were wowed by the solar panel-clad Emax Excalibur hybrid yacht. In other news, we shined a light on green consumer electronics this week as we brought you a lunar LED light modeled after the moon and Peter Rojas explained how wasteful it is to keep gadgets chargers plugged in as part of our Ask a Tech Geek column. We also shared a low-tech tablet that's perfect for kids, and we showcased a new type of climate-controlled clothing that beats the summer heat. Finally, we were excited to see Sprint launch a contest where you can recycle your old cell to score a Vespa scooter and an eco smartphone, and we brought you seven sustainable designs for a greener Fourth of July.
Quantum dots could coat the world in nano-sized solar panels
We've long believed in the mystical power of quantum dots, so it makes perfect sense to us that one day they'll be used to fully harness the Sun God's rays and thereby save the planet. The nano-particles turn light into electricity, and could potentially be manufactured cheaply and abundantly enough to coat surfaces in current-generating paint. The main obstacle to this has so far been efficiency: the clever little dots just don't work very hard. However, scientists at the University of Toronto now claim to have discovered a fix. Instead of using a single layer of particles, which can only harvest one meager wavelength from the full gamut of solar light, they added a second coat on top and configured it to be sensitive to an additional part of the spectrum. By adding third and fourth layers, the researchers hope to achieve a commercially viable efficiency of 10-percent within the next five years. We humbly call on Ra to be pleased with their efforts.
Europe's first solar powered train tunnel goes live on Belgian high-speed line (video)
The train ride from Paris to Amsterdam may not be the most scenic of European railway routes, but it's the only one capable of harnessing the awesome power of the Sun -- for two miles, at least. Yesterday, engineers in Belgium officially switched on Europe's first solar-powered train tunnel, spanning a 2.1-mile stretch of the rail line connecting the City of Lights to Mokum. The installation's 16,000 solar panels will be used to provide 50 percent of the energy needed to power nearby Antwerp Central Station and to provide extra juice for both high-speed and traditional trains. Originally developed to help protect travelers from falling trees in an ancient forest, the project is expected to produce up to 3.3MWh 3,300 megawatts hours per year, while decreasing annual CO2 emissions by about 2,400 tons. Speed past the break for some aerial footage of the artery, along with a brief PR from Enfinity -- the Belgian renewable energy company that helped bring it to life. Update: According to the AFP, the tunnel will produce 3,300 megawatts hours per year.
Eton's Soulra XL solar-powered iPod boombox will cost $300, now ready for your pre-orders
Summer's nearly here, the sun shining bright -- wouldn't you like to share your tunes with friends while basking in the light? That's what Eton's counting on as it prepares to ship the Soulra XL, the solar-powered iPod boombox formerly known as the Soulra 2. As we discovered at CES in January, its set of eight speakers get pretty loud, and Eton claims it charges twice as fast as its predecessor (five hours) thanks to a sizable monocrystal solar panel, and lasts five hours on a charge. It'll juice your phone, too. All told, you'll be schlepping around seven pounds and paying $300 for the privilege of completely cordless mobile sound. Sound like a deal? You'll find Eton ready to shake your hand at our source link.
Nokero's solar-powered, rainproof N200 light bulb: brighter, stronger, more flexible
No one's going to be calling Nokero out for falling behind. Just a few short months after revealing its first commercial light bulb for developing nations, the outfit has now rolled out a second version, the predictably titled N200. This guy strikes a vastly different pose compared to the original, with the LED enclosure hanging on a swivel that enables it to be positioned in a way that would optimally catch light. When night falls, users can flip the light north to create a lantern. Nokero claims that this edition is just as rugged and rainproof as the original, but it's 60 percent brighter and lasts three times as long. A single NiMH battery is included, and that's what is rejuvenated by the sun -- once charged, it'll provide between 2.5 and 6 hours of light, depending on the mode. It's on sale now for $20 apiece (bulk prices are less), representing a modest $5 premium over the (still available) N100. Can't say the Yankees will be looking to decorate their outdoor patio with lighting right about now, but for the nomads trekking to Panama to escape Old Man Winter... well, you know what to do. Vid's after the break. [Images courtesy of Larry Bollig] %Gallery-107898%
Puma Phone review
So it's true, we're living in an age where people would shamelessly line up for certain electronics and luxurious fashion items. Why? Just because they can, and for that reason, some swanky outlets -- namely Christian Dior, Prada, Giorgio Armani, Dolce & Gabbana, and Versace -- have attempted to exploit our gadget lust by offering self-branded phones at extortionate prices. In the eyes of every-day consumers, there's really not much appeal in these soulless devices except for the logo and some extra bling, but apparently these two factors alone are enough to make some aficionados drool a river. On the other hand, Puma -- a less luxurious but naturally more accessible fashion brand -- has decided to do more than just slapping an OS skin onto its aptly-named Puma Phone. Priced at a comparably affordable £300 ($469), this Sagem-made featurephone packs a few unusual features such as a solar panel, a sports tracker, and even a virtual cougar named Dylan. Read on to find out if we could sense the Puma spirit in this device.%Gallery-99609%
HomeSun to install gratis solar panels on UK roofs, hope for reimbursement
As the story goes, the UK government is helping to subsidize the installation of solar panels on homes around the country, and HomeSun is hoping to make a name for itself by providing a bit of encouragement for those on the fence. Reportedly, the outfit will be providing and installing 2.5 kWh to 4 kWh systems -- which typically range between £11,000 and £15,000 -- for precisely nothing on abodes with "optimally sited and sized roofs." Post-install, HomeSun will receive government funds over 25 years, and at any point, customers can buy the system off on a straightline depreciation basis and start receiving the feed-in tariff themselves. Better still, those who don't meet the "free" qualifications can still get in on the goodness for a one-time fee of £500 and a £5/month maintenance charge. We'd suggest you apply quick, though -- the company will only be installing 100,000 systems over the next three years.
Uplink Audio Strap System offers solar power for runners on the run
Designer Adam Hammerman's concept -- the Uplink Audio Strap System -- is for all you sports enthusiasts that want to listen to tunes while running but don't want to be bothered with headphones. It can connect with a variety of different mobile devices, and boasts four ultrasound speakers, meaning that you can hear the music but nobody else can, so you're not disturbing the peace! For outdoorsy types, of course, it would be a much safer system for things like running, since you would still be able to hear the street noise around you, and the device would also have flexible solar panels which charge the speakers on the go. It's just a concept for now, but one we'd like to see in reality.
Inhabitat's Week in Green: street-legal Tron lightcycles, electronic eyeglasses, and the American Solar Challenge
Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us. This week Inhabitat saw solar-powered vehicles blaze trails around the globe as the University of Michigan's sleek pod car crossed the finish line to win the American Solar Challenge. We also watched the Solar Impulse gear up for its first eagerly anticipated night flight -- a pivotal undertaking as the sun-powered plane prepares to circle the earth. In other clean transportation news, and we were stunned to see a set of street-legal electric Tron lightcycles pop up on eBay. The field of renewable energy also heated up this week as researchers revealed an innovative tri-layered solar panel that's capable of catching the full spectrum of the sun's rays. Wind power made waves as well as Principle Power unveiled a new ultra-sturdy ocean platform that's able to support the world's tallest wind turbines. Finally, we saw the light this week as Illumitex unveiled the world's first square LED bulb, which they claim is cheaper, more efficient and more practical than typical round bulbs. We also peered at an innovative new type of electronic eyeglasses that can change your prescription with the push of a button. And for all you shutterbugs looking to share your vision with the world, you won't want to miss this handy solar camera strap that ensures you'll never miss a shot.
Apple patents subsurface solar cells for media players
Patently Apple has revealed that Apple continues to explore solar power options for recharging its portables, including iPhones and iPads. The latest patent information is intriguing: rather than slapping a solar panel on the back of the device, Apple wants to embed the solar cells below the display. Essentially, there'd be no way to tell from the outside that the solar cells are even present. According to Patently Apple, the design of the next-gen iPhone prototype is suitable for this design, and if the backside of the case is glass or ceramic, Apple could put a double-sided solar cell in the device, potentially doubling the amount of charge it receives from the sun. The idea of solar power in an iPhone is interesting. I have a Solio charger for mine, and it's great for keeping my iPhone charged on long hikes. I'm skeptical about the utility of having solar cells built into the iPhone itself though, because how often are people going to leave their iPhones sitting unperturbed in direct sunlight for several hours? Perhaps this will be more geared toward prolonging battery life by a small amount rather than being marketed as a full-fledged charging solution. I can see Apple selling this solution as a way to get an extra hour or two of life out of your iPhone every day, but using the sun as the iPhone's only power source will be more difficult, particularly if you live somewhere that doesn't get a whole lot of sunlight. The concept is fascinating at any rate, and may be something we see in the 2011 models of Apple's portables. [Via 9to5Mac]
Quickertek selling solar panel for iPad
Back at Macworld, I checked out a company on the show floor that made solar (photovoltaic) panels. I was hoping to see a panel for sale ready to charge the iPhone, because an easy-to-use panel at a reasonable price would have probably had me opening my wallet on the spot. Unfortunately, they only made custom-designed panels, and nothing mass market (or in my price range), so I was disappointed. But this one might be what I was looking for: Quickertek, makers of all sorts of Mac-related accessories, has adapted its MacBook "Apple Juicz" solar panel to the iPad. This provides 10 watts of sun-based power (reportedly the same as the regular iPad charger) to your magical and revolutionary device. I don't have an iPad yet, and the price of the Apple Juicz (US$250) is still a little steep for me, even though it's probably cheap for what it is. But I am always in favor of using solar technology, and if you're doing something like camping in the middle of nowhere and using your iPad or MacBook a lot, this might be a workable solution. If nothing else, at least we're getting closer. Someday, photovoltaic panels will be so good at grabbing light and batteries will be so good at storing the generated power that all you'll need to do to charge your iPad is go read outside in the sun for a bit.

Casio's solar-powered Pathfinder watch plays the green card twice
Plotting their latest spread of watches this spring, Casio executives decided it was time to "go green." Some poor schmuck in R&D took them at their word. Thankfully for mother nature, the Casio Pathfinder PRG110C-3 is more than meets the eye; the watch -- suited for argonauts needing an altimeter, barometer, thermometer and digital compass -- also has a miniature solar cell built into its face to automatically recharge the battery. Though Casio's claim that this last will cut down on the three billion batteries Americans trash each year seems a little reaching -- watch batteries last a lot longer than a AA -- the timepiece does help the planet some merely by being packaged in recyclables. The $250 device will be available exclusively from Amazon, and yeah, the color you see here is the color you'll get.
Researchers shows off self-contained, 9mm solar power system
Advances in solar power aren't always the most immediately exciting sort of developments (a more efficient solar panel still looks like a solar panel), but this new solar power system developed at the University of Michigan certainly won't have any trouble turning a few heads. Not only is it 1,000 times smaller than any comparable commercial counterpart (just 9 cubic millimeters), but its processor, solar cells, and battery are all self-contained, and the researchers say it would be be able to operate "nearly perpetually" if not for the battery eventually giving out after "many years." What's more, they say the system could also be adapted to be powered by movement or heat instead of light, which means that it could eventually power medical implants in addition to a whole range of other devices. No word on when that might happen, but the inventors are already busily working to commercialize the device. Extreme close-up after the break.
LG GD510 Pop's solar panel add-on finally ships
Considering the LG Pop's milquetoast specs, the best thing going for it has to be its trick solar rear that's capable of injecting three minutes of talk time for every eleven minutes of sunshine you pour into it. Problem is, the panel was an accessory that didn't ship in the box -- you had to buy it separately, and back at the Pop's launch, it wasn't available. That's all been cleared up now with news out of LG's German press office that the panel's available for a stout €34.90 (about $49) on top of the phone's €169 ($236) sticker -- pricey, perhaps, but you figure you'll make it up in power savings over the course of a few years' use. Over the long term, all phones should have these suckers built in just for kicks, so let's hope LG's setting a precedent here.
Inside Sharp's new LCD factory, we can see our next HDTV from here
The path back to LCD leadership for Sharp begins at its just opened Sakai City manufacturing facility. Being a 10th generation facility means it can roll out more and bigger displays, producing six 60-inch LCDs from each glass substrate, 60% more than older 8g facilities. Check out the pics for a peek at where 72,000 substrates per month will be made, delivering those slim LED backlit televisions getting so much love, along with solar panels (also being installed on the roofs for that extra green vibe that's in vogue these days) and a few of the more than 100,000 energy efficient LEDs lighting the factory itself. Whether your closest HDTV purchase is a turkey fueled memory from last weekend or yet to come, bargain hunters and AV fans alike can appreciate an eyeful of the robots and testing equipment slicing, dicing and stamping screens headed for shelves nearby, whether bearing an Aquos brand or any number of other nameplates.
Regen's ReNu solar panel system in the flesh
While great in concept, solar powered gadgets just never seem to be very practical at the end of the day. Regen's tweak on the formula might help a little, by stuffing a battery into the solar panel itself, meaning you don't have to keep your iPod plugged in for a painfully long trickle charge or juggle multiple elements to make it work (there's a USB plug on the side). ReNu also has batteries in its various docking accessories as well, all of which can be charged by the ReNu panel or by AC power. It's not going to turn the emerging market on its head, and at $199 for the ReNu unit by itself it's not cheap either, but it seems like a logical direction for sun-fueled devices -- and looks pretty cool doing it.
ReNu solar panels announced for iPhone charger, sound dock, LED desk lamp
Sure, we've been frustrated by solar-powered iPhone chargers and amused by the irony of solar-powered lamps in the past, but that doesn't mean we're not looking forward to the day when we can meet our gadgets power needs without relying on fossil fuels. That's why we're pleased to note that a company called ReNu has just announced a solar panel that can be used to charge your iPhone or iPod, power the device's sound dock, or even keep your desk light shining sans mains power. Featuring a modular design, the panel can dispatched to your window to soak up the rays for 10 or 20 hours (depending on the amount of sunlight it receives) and then returned to your dock for about nine hours of music playback, recharge your iPhone (twice!), or provide about four hours of light with the LED desk lamp. Of course, most people are going to hang this thing in the window once, forget about it, and then spend the next several years powering their devices with the included AC adapter -- but at least they're trying, right? Available for pre-order now, the ReNu solar panel ($199) and the Renu panel / iPod dock combo ($249) both ship in February 2010, while the Side Light desk lamp ($89) ships in next March, and the Sound Dock ($149) should see the light of day sometime in April.

TDK unveils fashionable, colorful solar chargers (video)
Solar power is something we've seen touted in every big tech trade show for as long as we can remember, but it's taken until recently to make it a bit easier on the eyes. Enter TDK's design-, color-, and sun-enhanced chargers, found hanging out under a hard light in the back of the company's CEATEC booth casually powering a fan. It's definitely a step up from dark paneling, so how long until we see this applied to some stylish mobile phones, eh world? Video after the break. %Gallery-74891%
Samsung's E1107 with built in solar panel gets a thorough shakedown
Sure, a cellphone made out of 80 percent recycled materials might be considered pretty environmentally friendly, but a cellphone with a built-in solar panel? Now that's something with the potential to make Al Gore cry. Enter the Samsung E11077. It's solar panel-equipped back cover comes in at 1.2-mm thin, and is said to revive a dead battery after just 15 minutes in the sun. Besides the FM radio and flashlight features, the only other noteworthy addition is an "Eco" profile, that essentially just changes screen brightness and shuts the Bluetooth off. If you're interested, the cost of entry is a reasonable $59, but you'll probably have to find an importer, as we don't expect this tree hugger to land stateside any time soon. [Thanks, Vadik]
