Apple breaks ground on second solar farm for North Carolina data center
Last February, Apple came clean about its efforts to clean up the environment, detailing intentions to make its Maiden, NC data facility a greener place. That site, already home to one solar farm, is now set to host a second 20 megawatt photovoltaic array spanning 100 acres, a one-two power punch that'll jointly generate 84 million kWh annually. Combined with the company's in-development biofuel cell plant, scheduled for opening later this year, that theoretic yield should hit the 124 million kWh mark -- an amount sufficient to power nearly 11,000 households -- providing 60 percent of the center's electric demands. Still, that's not enough to adequately keep operations afloat, so for that very necessary, leftover 40 percent, the house that Jobs built plans to purchase similar clean energy from outside local sources. When all is finally up and running smoothly, the southern facility will earn the distinction of "most environmentally sound data center ever built." Or, at least until another well-heeled competitor comes along to contest that title. Now that's a friendly competition we can get behind.
Researchers use virus's rogue traits to create electricity from motion
Viruses are the swarming bullies of biology, but it turns out their alarming self-replication could one day power your iPod. We've seen them in batteries before, but researchers at Berkeley Labs have now coated electrodes with modified M13 bacteriophage, a harmless bacteria-eating virus, to create the first ever organic piezoelectric material -- which can convert force to electricity. The team explained that such a substance would be non-toxic, organize naturally into thin layers and self-regenerate, giving it a possible advantage over chemical options. In theory, by attaching a thin film of it to your shoes, power could be generated when walking, lending volts to the myriad electronics we pack around nowadays. To see a finger-powered video demo of our frequent-enemies making themselves useful for a change, stroll on past the break.
Study says wind turbines raise surrounding area temperature, but only at night
Who said the butterfly effect couldn't apply to renewable energy? Though wind farms are considered pretty green on the energy-generating spectrum, it looks like they, too, have an impact on the planet. According to a study published today in the journal Nature Climate Change, turbines can raise the local temperature -- albeit slightly. From 2003 to 2011, researchers monitored satellite data for west-central Texas, which is home to 2,350-plus turbines and four of the world's largest wind farms. In that decade, scientists observed a temperature increase of 0.72 degrees in wind farm regions compared to areas without turbines. That warming trend was especially marked at night, when the temperature difference between the ground and the air is highest. The temperature increase was also higher in winter; researchers say that these cooler, windier conditions cause turbines to generate more electricity and therefore create more heat. Since the study didn't find any change in daytime temperatures, it looks like we don't have to ring the global warming alarm just yet.
Helium-filled floating wind turbine, renewable energy with style
There's no doubting that the cause of renewable energy is a noble one. But, ethics aside, it also gives birth to the occasional technical marvel. Altaeros Energies, a company from Massachusetts (with MIT and Harvard blood in its veins) has created one such curiosity. The prototype is a wind-turbine that doesn't just languish on a hill-top, cutting a line in the horizon. No, this one has a helium-filled outer-section which allows it to deploy itself to 1,000 feet, where it can benefit from stronger, more consistent winds and gives nearly twice the power yields of its land bound brethren. That's all very nice, but we just thought it looked dang cool in action.
Delaware Ph.D. student hopes to solve energy woes with renewable hydrogen production
Hydrogen fuel is a fickle mistress. On one hand, it teases us with the promise of renewable energy and a cleaner tomorrow. On the other hand, it's most often produced with natural gas as the source -- hardly the clean break from fossil fuels that many had envisioned. Fortunately, there are other methods to harness this abundant element, and a doctoral student at the University of Delaware may have created a worthwhile process. Similar to previous research we've seen -- which relies on ceric oxide and energy from the sun -- Eric Koepf has designed a reactor that combines zinc oxide powder, solar rays and water to derive hydrogen as a storable energy source. Most intriguing, it's thought that the zinc oxide byproduct from the reaction will be reusable -- a potential gateway to sustainable energy. Koepf will spend the next six weeks in Zurich at the Swiss Federal Institute of Technology, where his reactor prototype will be put through its paces to determine its efficiency and effectiveness. If successful, his advisors envision that one day, we may see giant versions of Koepf's reactors producing hydrogen on an industrial scale. We certainly won't fault them for dreaming big.

Apple touts solar array at North Carolina Data Center
Apple has updated its Apple and the Environment web page with information about the huge new data center in Maiden, North Carolina. This US$1 billion, 500,000 square foot facility is the home of Siri and part of the backbone of iCloud. Not only has the facility already earned a LEED (Leadership in Energy and Environmental Design) Platinum certification, but the company has plans to power the facility primarily with renewable energy. According to Apple, the LEED Platinum certification from the U.S. Green Building Council is unique -- "We know of no other data center of comparable size that has achieved this level of LEED certification." As for the renewable energy plans, Apple notes that they have "major projects under way to achieve this." Those projects include building the largest end user-owned solar array and non-utility fuel cell installation in the U.S. Last October, Apple received the OK from Catawba County officials to reshape 171 acres of land adjacent to the data center in preparation for installation of the photovoltaic solar array. The Maiden data center won't be the first Apple facility to use renewable energy: The Apple Facility Report for 2011 notes that company sites in Elk Grove, California, Cork, Ireland, and Austin, Texas use 100 percent renewable energy resources. Apple also added biogas-powered fuel cells at the Cupertino campus in late 2010 to reduce carbon emissions.
Two US startups break solar efficiency records, aim to light up your life
Two US startups are breaking solar efficiency records in their quest to bring clean, cost-effective, eco-friendly energy to a power grid near you. Alta Devices, based in Santa Clara, CA, has achieved a 23.5 percent efficiency rating with its standard solar panel, while Semprius, a Durham, NC company, has achieved a rating of 33.9 percent with its concentrated photovoltaic offering -- besting the previous records of 22.9 percent and 33 percent, respectively. Interestingly enough, both outfits chose to utilize a new material to construct their sun-sopping cells: gallium arsenide. The material, while more expensive, is better suited for absorbing the sun's energy, especially when compared to silicon, the cheaper element typically used. Alta and Semprius are looking to proliferate solar power by further refining the technology, making its price per kilowatt equivalent to that of fossil fuels without the use of government subsides. Here comes the sun...

Scientists create first solar cell with over 100 percent quantum efficiency
Researchers over at the National Renewable Energy Lab have reportedly made the first solar cell with an external quantum efficiency over 100 percent. Quantum efficiency relates to the number of electrons-per-second flowing in a solar cell circuit, divided by the number of photons from the energy entering. The NREL team recorded an efficiency topping out at 114 percent, by creating the first working multiple exciton generation (MEG) cell. Using MEG, a single high energy photon can produce more than one electron-hole pair per absorbed photon. The extra efficiency comes from quantum dots 'harvesting' energy that would otherwise be lost as heat. The cell itself uses anti-reflection coating on a transparent conductor, layered with zinc oxide, lead selenide, and gold. NREL scientist Arthur J. Nozik predicted as far back as 2001 that MEG would do the job, but it's taken until now for the concept to leap over from theory. The hope is, of course, that this will lead to more competitively priced solar power, fueling the transport of the future.

NTT DoCoMo to power cellphone towers with renewable energy, tenderness
When they're not busy carving handsets out of teak (or rockin' out with their pupils), the folks over at NTT DoCoMo apparently focus their efforts on saving the environment. Next year, the Japanese provider will begin outfitting its expansive cellphone tower network with ten "green transmission stations," to be powered by an artillery of biofuels, wind and solar energy. This kind of infrastructure would obviously bring a smile to the face of ol' Mama Nature, but it could also help mitigate the adverse effects of power outages and elfin insurgents. And for that, we should all be grateful.
Strawberry Tree brings free, solar-powered charging to Belgrade's BlackBerrys, more (video)
Dead battery in Belgrade? Head to the city's Obrenovac district, where a group of students has developed the world's first public charging station powered entirely by solar energy. Known as the Strawberry Tree, the structure's 16 ports support a variety of handhelds, allowing pedestrians to juice up their cell phones in just ten to 15 minutes, at no charge. Its built-in batteries can also store up to a month's worth of back-up energy, enabling the station to hum along at night, or even during Serbia's less sunny seasons. In the first 40 days following its November launch, the Strawberry Tree logged some 10,000 charging sessions -- or about ten charges per hour. Creator Miloš Milisavljevic was just 17 years old when he came up with the idea, and now, at the ripe old age of 22, is looking to plant new stations across other Serbian cities, through his Strawberry Energy NGO. He says these installations won't generate much revenue from consumers, but that's not really the idea: "Energy from the sun is free, and it would be unethical to charge people to use the Strawberry Tree...We are trying to inspire young people to think about the source of the energy they use, and behave and act responsibly." You can check out the Strawberry Tree in the video below, or find out more about Milisavljevic's ideal-driven endeavors in the full PR.
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.
Google's search for future profit targets the Sun, not just the cloud
These humble-looking contraptions were revealed in a Google patent application for a "heliostat control system" that automatically adjusts solar thermal mirrors to their optimal energy-harvesting angle. A camera and computer are housed in the central tower that receives heat from the mirrors, and together they detect when a heliostat is misaligned and then correct it using actuators. Sound like a strange distraction for an Internet company? Google thinks not. It's already invested $168 million in the world's largest solar tower in the Mojave Desert as part of its effort to both reduce its own massive electricity bill and diversify its business. It's also currently hiring three new technical staff to make this happen. Interested?
Solar Impulse completes first solar-powered international flight, Captain Piccard returns to earth
We're big fans of charming, ungainly Solar Impulse, and of Captain Bertrand Piccard and Andre Borschberg's quest to circumnavigate the globe in a solar-powered plane. In case you missed the live stream: the Swiss flier just got a little closer to that goal by completing its first international flight, taking off near Berne, Switzerland and landing in Brussels, Belgium, just under 13 hours later. That's half the flight time of an earlier test, in which the craft's 200-foot wingspan, covered with 12,000 photovoltaic solar cells, kept it aloft for 26 hours. Of course, a controlled test flight is one thing -- making solar-powered flight commercially viable means proving your plane can successfully navigate busy airspace. To see Solar Impulse come in for a smooth landing, peep the video after the break.
Newly discovered properties of light promise better solar batteries, really great tans
Are you tired of waking up to the same old semiconductor-based solar array? Do you yearn for a change? We know you do and, thanks again to the wonder and mystery of magnetic fields (they're not just for stopping speech anymore), there's a new day dawning. University of Michigan scientists were shooting lasers at glass, as they do, and made a remarkable discovery: light passing through a non-conductive surface like glass generates impressive magnetic effects – up to 100 million times greater than expected. The resulting magnetic force could replace the electric effect exploited by current technology, paving the way for "optical batteries." Though different from the Wysips transparent photovoltaic cell, the technology could have similar applications and may render obsolete those massive solar farms. No need to worry, though -- your stylish solar backpack is as fly as it ever was.
MIT professor touts first 'practical' artificial leaf, signs deal with Tata to show up real plants
A professor at MIT claims to have Mother Nature beat at her own game. Dr. Daniel Nocera says his invention is ten times more efficient at photosynthesis than a real-life leaf, and could help to bring affordable alternative energy to developing countries. Described as an "advanced solar cell the size of a poker card," the device is made of silicon, electronics, and inexpensive catalysts made of nickel and cobalt. When placed in a gallon of water under direct sunlight, the catalysts break the H2O down into hydrogen and oxygen gases, which are then stored in a fuel cell -- the energy produced is apparently enough to power a single house for a day. Of course, this isn't the first time we've seen scientists try to one-up nature, in fact, we've seen solar-powered leaves before, but this thing actually looks poised for the mass market -- Nocera signed a deal with Tata in October. Full PR after the break.
New York City turns to sewers for energy solutions
Listen up New Yorkers, those hot nuts you just swallowed could be used to light the signs on Broadway. Okay, so that's a stretch, but the city's Department of Environmental Protection (DEP) just issued a plan to turn the stuff you flush, along with rest of its wastewater, into renewable energy. New York City produces about 1.3 billion gallons of wastewater daily, yielding 1,200 tons of biosolids that can be harvested to procure methane -- already accounting for 20 percent of the city's energy -- and butanol, a clean gasoline alternative. The plan, which also includes wind and solar projects, aims to use gas, converted by large digesters, to "power wastewater operations, meet on-site heat and electricity needs, and, where feasible, sell excess energy to the market." As the DEP points out, the plan isn't far fetched -- we've seen a couple of solutions for turning human excrement into usable energy, and a project already under way in Greenpoint is estimated to procure enough methane over the next year to heat 2,500 homes. Now, if that doesn't give you a newfound respect for the porcelain throne, we don't know what will.
