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.
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.
California raceway gets 1,600 solar panels, flaunts green track status
As far as sports go, the one where you drive cars around in circles several times is likely not one of the most energy efficient. With that in mind, it's nice to see locations like Northern California's Infineon Raceway working toward sustainability, announcing this week the installation of more than 1,600 solar panels. The panels, manufactured by Panasonic, will provide around 41-percent of the Infineon's energy usage. Also on its list of earth-friendly features: a solar-powered billboard and 3,000 sheep, which take care of a lot of the lawn mowing on the grounds and apparently aren't of the electric variety.
KDDI's biblio Leaf SP02 priced, due out Christmas Day in Japan (update)
E-readers are flooding the market these days, and KDDI has delivered its most recent offering just in time for the holiday season. Since the biblio Leaf SP02's specs were first released, battery life seems to have grown to 13,000 pages, with presumably a few extra thrown in courtesy of its solar array. The device utilizes KDDI's LISMO Book Store and its 20,000 titles to obtain content, and if that isn't enough reading material for you, the company claims that five times as many titles will be available by 2012. All this can be had on Christmas day -- if you're lucky enough to hail from the land of the rising sun, that is. Update: Details on the e-reader, much like the device itself, seem to have gotten lost in translation. As a few readers have pointed out -- and our own Engadget Japanese editor Ittousai confirms -- the SP02 has an "open" price of around ¥15,000 (about $180 in US currency), with 3G prices ranging from ¥525 per month for data on a two-year contract, or ¥1,575 without ($6.28 vs. $19, respectively).
Proposal would put a solar garden on the Brooklyn-Queens Expressway
If you've ever spent any time on New York City's finest roadway, the Brooklyn Queens Expressway, garden is not one of the first words that comes to mind. That could change on one particular strip in Brooklyn if a concept -- which you see above -- gets approved and built. The concept is part of a project calling for solutions to a trench that runs from Carroll Gardens to the Columbia Street Waterfront in Brooklyn. Starr Whitehouse Landscape architects floated three possible solutions for improving the stretch, which would cost between about $10 and $18 million, very cheap in comparison to other projects of this type. The Green Canopy proposal calls for a massive plant covered canopy with solar panels to stretch over top of the entire area making it self-sustaining and reducing noise in the area. Hit up the source to check out the other proposed projects.
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.
Toshiba's Charge Grid puts your solar panels to work, smartly charges your EV
Got a bunch of photovoltaic cells and a vehicle that requires electricity? Toshiba's thought up a process dubbed "Charge Grid" by which you can juice the latter efficiently. When the sun's out and the electrons are flowing, it doesn't pay to put them into the grid, so this system stores them in a rechargeable battery ready to rapidly charge your EV. For nighttime when the electricity rates are low, a bidirectional inverter lets you hop right back on the neighborhood grid, so your solar cells are put to good use and your car is always well fed. The company tells Tech-On commercialization of the system is still a few years away, so you've plenty of time to raze that roof antenna in favor of some photosynthesized electricity.
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.
Caption contest: solar suits, or the future of punishment for eco-abusers?
We get the impression that these guys are really just putting the pressure on "evil corporations" to stop grounding mountains in the everlasting search for coal, but it's not really the environmental activism that caught our attention here. Rather, it's the fact that we're 84.3 percent certain we saw these exact same characters in a Daft Punk video back in college. Seriously -- check the video out after the break and tell us we're loony. Josh T.: "Totally off the grid in regard to both power and girlfriends." Thomas: "And now Solar Sprockets, we dance!" Joe: "You have to go as far as Brussels to find a Devo tribute act worth its salt." Richard Lai: "In the future, humans won't need to eat." Paul: "Sure, they know how to capture the electricity, but do they know what to do with it?" Justin: "In the future, all bands will play the washboard." Laura: "Did anyone make a Beastie Boys joke yet?" Darren: "SABOTAGE." Richard Lawler: "This is not what Boston meant when they said I take what I find."
CoolerBot photographs nature, gets its power from it
If you're into real life bunny wabbits and other such wildlife, but not a fan of the cold, wet and windy outdoors, what do you do? We'd say just boot up the console and shoot you some pixelated peoples, but Steve Norris' idea might be just a tad more practical. He has authored the above mobile snap-station, which is equipped with an infrared video camera, a Nikon DSLR, and pairs of motors, 10Ah batteries, and solar panels. Power flows from the latter into the former to turn wildlife stalking into a pleasurable pastime for even the most indoorsy of folks. Video demonstration of the hardware after the break.
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.

Dell and Envision Solar refashion parking lot into clean energy farm, EV recharge station (video)
Dell has added a shiny new feather to its cap today with the announcement of a freshly completed Solar Grove renewable energy installation. The system is composed of 512 solar panels, which provide shelter for 56 cars, and are capable of harvesting 131,000 kWh of energy per year. This power will be primarily used in the adjacent Round Rock HQ, but CleanCharge stations will also be available should you wish to juice up your electric vehicle on Mother Nature's finest. No matter how much Dell might have splashed out to bring this integration together, we can't help but suspect that the smug satisfaction of getting free energy -- both in pecuniary and ecological terms -- must be priceless. Video awaits after the break.
DIY Solar Flyer motorcycle tearing around Phoenix, Arizona
Phoenix area resident and motorcycle enthusiast Richard Gryzch got tired of gassing up his bike all the time, and he decided to do something about it. Rather than getting a fancy electric motorcycle, he modded one for himself -- making an electric bike that is seemingly covered in solar panels. The motorcycle uses no gas, goes up to about 90 miles per hour and has a range of around 50 miles. There are very few details about the inner workings of the bike, so we're loathe to say it's 100 percent solar, but Richard does plan on extending his bike's range of 300 miles. Hit the read link to watch an extremely tiny video of Richard and his bike.
DS Lite solar panel mod lets you leave the PSU at home
If you've got some 60 x 60 solar panels, a few diodes, some scotch tape, and a little time on your hands, you may never need to plug in your DS ever again. According to "dark sponge," a poster over at Instructables, you can convert the Lite into a solar-powered wonder that will obviate the need for your standard PSU, and make your green leaning friends, er... green with envy. The mod involves slapping panels on both the bottom and top of the device which -- when wired in parallel -- get 6 volts of power at 80 mA, which is apparently perfect for a trickle charge. The only downside is you'll have to leave the device face down for a bit, and it's advised to keep it out of the sun all day. Still, it's an excellent mod that doesn't seem too difficult to execute, and ends up saving hassle and energy... and who can knock that? [Via SlashGear]
Next-gen Prius now official, uses solar panels to keep car cool
The very shoe-like 2010 Toyota Prius has made its official debut at this week's Detroit Auto Show. The company estimates it'll have a 50 MPG rating -- up from 46 MPG in the previous model -- and there's a bigger, 1.8-liter four-cylinder engine for improved highway mileage. In addition to Power and Eco driving modes, EV Drive will let you run on battery alone for about a mile, which if nothing else should provide a little extra push for getting to the gas station when you've held off for too long. One of the coolest (literally) new features is the optional solar panels in the moonroof that will generate power for circulating air and keeping the interior temperature from going too high. If that's not enough, there's a remote-controlled A/C system that can run on battery alone and lets you set the temperature before you get in. Check out the read link for more specs and the full press release.
Inexpensive solar panels nearly ready for commercialization
We've been inching closer to low(er) cost solar panels (for the mainstream public to enjoy) for some time now, and apparently, AVA Solar Inc. is just about ready to start cranking out units that "will cost less than $1-per watt by the end of next year." The technology was reportedly developed by Colorado State University's Professor W.S. Sampath, and production is slated to begin soon in a "200-megawatt factory" that could employ some 500 individuals. Of note, it was said that the "cost to the consumer could be as low as $2 per watt," but even that figure purportedly rings up at about half the cost of current options.[Via Slashdot, image courtesy of CSU]
Pink solar cells provide green power on the cheap
The race to build a cheaper solar cell continues to produce results, as researchers at Ohio State have developed a nanotech solar cell with a unique pink color that they say will one day be able to produce as much power as traditional silicon cells for a quarter of the cost. The dye-sensitive solar cells, or DSSCs, get their pink color from a mixture of ruthenium and either titanium or zinc oxide particles that absorb sunlight, while nanowires link the particles to provide power transfer. So far the team have gotten the cells to produce half as much power as traditional cells, but the next step is to start using nanowire "trees" to improve efficiency to equal or surpass those levels. No word on when we'll see this tech hit the market, but surely the prospect of a hot pink solar Cadillac isn't too far off.[Photo is of an unrelated DSSC concept from New Zealand]
Sharp solar panel system installed at AT&T Park
While you were busy watching Vladimir Guerrero take home the Home Run Derby crown two nights ago (not to mention the All-Star game last night), you may not have been aware that AT&T Park was feeding uber-clean energy back into the grid serving PG&E's customers throughout northern and central California. Sure enough, the home of the San Francisco Giants is now also home to 590 Sharp solar panels located in three separate areas of the stadium, which combine to generate some 120-kilowatts of electricity. The size of the entire array is reportedly "equivalent to approximately 40 residential solar systems," and while this system won't conjure up as much power as the CIS Solar Tower, it will certainly make good use of the ballpark during the off-season.[Via EETimes image courtesy of MatrixCS]
New Zealand peeps imitate plants to do solar on the cheap
Obviously, scientists didn't exactly originate the idea of harvesting energy from the sun when they started slapping together solar cells -- plants have been up on this whole photosynthesis mojo for a good long while. Now some researchers at Massey University in New Zealand have developed a range of synthetic dyes from organic compounds that closely mimic the light harvesting that goes on in nature. Other scientists have been pursuing similar solar techniques, but there's a major difficulty in getting the dyes to pass the energy on for actual use. After 10 years of research, the Massey scientists claim to have "the most efficient porphyrin dye in the world." Benefits of the dyes over traditional silicon-based solar panels include the ability to operate in low light, 10x cheaper production, and flexible application -- starting with canvassing roofs, walls and windows, but eventually moving on to wearable items that can charge your electronics stash. A working prototype for "real applications" should be ready in a couple years.[Via The Raw Feed]
