Wave generator supplies US electrical grid for the first time
A prototype wave generator called Azura is supplying grid power to Hawaii, the first time such a feat has been officially verified, according to the US Department of Energy (DoE). Though it can only produce 20 kilowatts, the DoE said that similar devices could eventually provide large amounts of clean power to coastal cities. The project is co-sponsored by the US Navy and was developed by an Oregon-based company called Northwest Energy Innovations (NWEI). It's located at the Navy's Wave Energy Test Site in Kaneohe Bay in Oahu, at a depth of about 30 meters (100 feet).
IBM's new computers may change how we process big data
IBM HQ. INT. DAY. An oppressive curtain of rain beats down against the window of this small meeting room in IBM's New York HQ. Two IBM scientists are engaging in excited conversation with a representative from the DEPARTMENT OF ENERGY while a third IBM employee sits at one end, removed from the action, chewing their pen and staring out of the window. DOE REPRESENTATIVE: What do you mean $300 million won't get me the two supercomputers I need? SCIENTIST #1: You're generating too much data. There isn't enough bandwidth for it all to go through. DOE REPRESENTATIVE: I don't understand. You're the supercomputer company, make it happen!
Researchers create algorithms that could help lithium-ion batteries charge two times faster
Researchers at the University of California San Diego have devised new algorithms that could cut lithium-ion battery charge times in half, help cells run more efficiently and potentially cut production costs by 25 percent. Rather than tracking battery behavior and health with the traditional technique of monitoring current and voltage, the team's mathematical models estimate where lithium ions are within cells for more precise data. With the added insight, the team can more accurately gauge battery longevity and control charging efficiency. The group was awarded $415,000 from the Department of Energy's ARPA-E research arm to further develop the algorithm and accompanying tech with automotive firm Bosch and battery manufacturer Cobasys, which both received the remainder of a $4 million grant. Wondering if the solution will ever find its way out of the lab? According to co-lead researcher Scott Moura, it'll see practical use: "This technology is going into products that people will actually use." Update: UC San Diego reached out to let us know that they were awarded $415,000 (not $460,000 as previously noted) out of a grant totaling $4 million (not $9.6 million), split between Bosch and Cobasys. We've updated the post and the press release below to reflect the correct figures.
Microbial music: Using sound to represent data from the deep blue sea
Science and music, many would say opposite sides of the same coin. Unless you're DOE biologist Peter Larsen at the Argonne National Laboratory, who would probably argue your legal tender has been double-headed all along. While Larsen is more likely to be studying the intricacies of microbes than Miles Davis, his latest work puts the two of them closer than ever before. Faced with the task of studying vast amounts of microbial data gathered from the English Channel, the biologist explored alternative ways of making sense of it all. While he could have made a spiffy set of charts, Larsen claims that there are certain parameters, like sunlight and temperature, that give the data a structure that lends itself to musical representation. While classical music might seem the typical choice, due to the irregular nature of the data, the result is more free-form jazz, yet still surprisingly musical. If you were wondering if there is something particularly groovy about the microbes in the English Channel, there isn't. Larsen and his colleagues used a similar idea in previous work looking at the relationship between a plant and a fungus. This isn't the first time data has been "sonified," but these processes that might initially seem to have no relation to music, rhythm and melody, actually highlight the patterns in natural phenomena.

US launches first commercial tidal power project this summer, Maine to reap moon's gravitational benefits
Solar may be the green energy source that's been hogging the headlines lately, but there are other fossil-fuel free ways that can help meet society's electrical needs. One of these is tidal power, and the US is set to start harnessing the ocean's electricity-generating potential this summer with the TidGen Cobscook Bay project -- the first such commercial project in the States. Located just off the coast of Eastport, Maine, turbines will be placed in 50-100 feet deep water to take advantage of the 100 billion tons of water that flow in and out of Cobscook Bay each day. When the project goes live, it'll feed into the public power grid and generate enough juice to power between 75 and 100 homes, and the plan is to eventually install enough turbines to generate 3MW of power -- which should cover the needs of over 1,000 homes and businesses. There's more info, plus plenty of political self-congratulation in the source below.
NVIDIA scores $12.4 million contract from the DOE to help FastForward exascale computing
Sick and tired of waiting around for some exascale computing? So's the Department of Energy. The agency has offered up a $12.4 million contract to NVIDIA as part of its FastForward program, an attempt help speed up exascale development. The chipmaker will be using the two-year contract to help develop architecture for an exascale computer that operates at a "reasonable power level," in order to "advance the frontiers of science." Possible implications for exascale computing include the study of climate change, development of efficient engines, the search for disease cures, according to NVIDIA -- not to mention "reasons of national security and economic competitiveness."
With federal loans blocked, Fisker halts work on Project Nina, lays off 66 workers
Fisker Automotive's bumpy 2011 appears to have given way to an even rockier 2012. A little more than a month after recalling 239 of its Karma plug-ins, Fisker has now stopped working on its second electric vehicle, following the US government's decision to suspend its federal loans. The manufacturer confirmed the news in an email yesterday, adding that a total of 66 workers in Delaware and California have been laid off, as a result. In 2009, the Department of Energy provided Fisker with $528.7 million in federal loans, but according to spokesman Roger Ormisher, access to those funds have been blocked since May. The money was supposed to be used to launch the Karma and Fisker's second, US-manufactured EV, known as the Nina. The Karma began rolling out to market in July, but did so well behind schedule, spurring the DOE to suspend its loan."Our loan guarantees have strict conditions in place to protect taxpayers," Department spokesman Damien LaVera explained in an email to Bloomberg. "The department only allows the loan to be disbursed as the company meets certain milestones and demonstrates results." Thus far, Fisker has drawn on only $193 million of federal funds and is looking to renegotiate the terms of the loan, in the hopes of accessing the remaining $336 million. The DOE, however, is still under intense scrutiny because of September's Solyndra debacle, so it's difficult to say what a renegotiated deal would look like. The manufacturer, for its part, says it's taking no risks, telling GigaOM that it "continues to pursue alternative funding sources." In the meantime, it'll continue to focus on the Karma for 2012, and hopes to revive Project Nina at a later date.
X-ray laser bakes solid plasma from aluminum foil, brings us closer to nuclear fusion
Nuclear fusion, like flying cars, is one of those transparent, dangling carrots that've been stymying the scientific community and tickling our collective noses for decades. But recent research out of the Department of Energy's SLAC National Accelerator Laboratory might help us inch a few baby steps closer to that Jetsonian future. The experiment, conducted by a group of Oxford University scientists, utilized the DOE's Linac Coherent Light Source -- an X-ray laser capable of pulsing "more than a billion times brighter" than current synchrotron sources -- to transmute a piece of aluminum foil heated to 3.6 million degrees Fahrenheit (or 2 million degrees Celsius) into a cube of solid plasma. So, why go to such lengths to fry a tiny piece of metal at that extreme temperature? Simple: to replicate conditions found within stars and planets. Alright, so it's not that easy and we're still a ways off from actually duping celestial bodies, but the findings could help advance theories in the field and eventually unlock the powers of the Sun. Until that fateful day arrives, however, we'll just have to let these pedigreed pyros continue to play with their high-tech toys.
Cheap electronic skin edges us closer to cyberpunk future
Researchers working for the Department of Energy's Berkeley Lab have figured out how to create relatively inexpensive "electronic skin" comprising carbon nanotubes enriched with semiconductors. Their process involves an enriched single walled carbon nanotube (SWNT) solution embedded in a honeycomb pattern of hexagonal holes to make it more flexible and stretchable - it's so limber, they wrapped it around a baseball, as you can see in the photo above. Combined with inkjet printing of electrical contacts, the technology paves the way for making flexible, wearable computers and a host of other cool things that William Gibson and other cyberpunk authors thought of back in the 1980s: smart bandages, flexible solar cells and electronic skin that can sense touch. Bring on the Zeiss eye implants and neural interface jacks!
Aptera fresh out of greenbacks, closes up shop
Bummer for fans of teardrop shaped three-wheelers, as your favorite chariot, Aptera's 2e, will never see the light of day. Despite getting the ball rolling on a $150 million loan from the DOE, subsequent funding and time just weren't on the startup's side. An unfortunate prognosis, as CEO Paul Wilbur revealed the company had been working on a $30,000 mid-sized sedan that would have touted 190 miles of electrical range. He's still adamant the company had "never been closer" to realizing its vision, but hopes someone else can carry on Aptera's torch. Those nuggets and more await in what is possibly the company's final tell-all after the break.
Chevy Volt under 'formal safety investigation' by NHTSA due to post-crash fire concerns
The Chevy Volt's lithium-ion battery may be great for a lot of things -- like low gasoline-dependency, for instance -- but when it comes to government regulated crash tests, it's proving to be a fiery problem. As the story goes, back in May, the National Highway Traffic Safety Administration put a Volt through standard side-impact crash testing, and in doing so, "the vehicle's battery was damaged and the coolant line was ruptured." The big issue? The car went up in flames multiple weeks later, seemingly as direct result. That event prompted the NHTSA to further study the safety of the batts in the period after a crash, which culminated in more tests performed just over a week ago to find out if they would prove volatile again -- simply put, they did. The group recently explained that it's "concerned that damage to the Volt's batteries as part of three tests that are explicitly designed to replicate real-world crash scenarios have resulted in fire." Because of this development, the NHTSA (with assistance from the Department of Defense, Department of Energy and General Motors itself) has officially launched a formal investigation into the Volt to ensure that its current battery implementation isn't a safety defect. Despite the announcement, the agency notes that of all the Volts currently zipping along the streets, there has yet to be a to be a similar incident out on the open road. The NHTSA further clarified that there's not yet any reason for current owners to worry, so long as they haven't been in an accident with their vehicle. Overall, GM describes the whole investigation as "procedural" at this point, stating that both GM has been working with the NHTSA for over six months on a "broader program designed to induce battery failure after extreme situations." Seems a bit late at this point, but in any event, you'll find full details in the press releases from both parties just past the break.
New nanotube battery technology leads to blisteringly fast recharges, improved safety features
Some day, your restroom break may be enough time to charge your [insert nifty gadget here] halfway. A group of researchers at the Department of Energy's Argonne National Laboratory has discovered that nanotubes composed of titanium dioxide can switch their phase as a battery is cycled, gradually boosting their operational capacity. The upshot: laboratory tests showed that new batteries produced with this material could be rejuvenated to 50 percent of their maximum charge in less than 30 seconds. This was accomplished by replacing conventional graphite anodes with titanium nanotube andodes. Following the experiment, lead researcher Tijana Rajh and her colleagues noted that as the battery cycled through several charges and discharges, its internal structure began to orient itself in a way that dramatically improved the battery's performance. Furthermore, using anodes composed of titanium dioxide instead of graphite could improve the reliability and safety of lithium-ion batteries and help avoid scenarios in which the lithium can deposit on the graphite anodes, causing a dangerous chain reaction known as "thermal runaway." Copious amounts of related technobabble can be found in the links below, and there's a video just past the break, too.
Philips wins DOE's $10 million L Prize for 60W incandescent killer
Put your pig-tail light bulb aversions aside, because Philips has just won the DOE's $10 million L Prize Competition for the creation of a decidedly non-curlicue 60W equivalent LED lighting solution. The company was named the first winner in the 60W replacement bulb category at a Washington DC event, yesterday. It's taken three years to find a winner that could meet the high standards set forth by the DOE, specifically "ensuring that performance, quality, lifetime, cost, and availability meet expectations for widespread adoption and mass manufacturing." Requirements further stipulated that the 60W incandescent killer use less than 10 watts of power, and provide energy savings of 83 percent. If Americans replaced all of their 60W incandescents with Philips' little winner, the DOE estimates savings of $3.9 billion in a single year. The bulb is expected to hit shelves as soon as early 2012. Full PR after the break.
142 electric vehicle charging stations head to Massachusetts, Nantucket and MV not included
Things are lookin' up in New England -- particularly for those who crisscross Yawkey Way with an electric vehicle. A grand total of 142 EV charging stations are slated to hit The Bay State in the coming months, with 25 communities across the commonwealth to get gifted. Boston reports that the majority of 'em will be in "common commuter or traveler spots," places like downtown parking garages, MBTA lots, shopping malls, etc. The bulk of the boxes will be part of the ChargePoint network, and we're told that the rates for recharging will be set by "municipalities on public land and by property owners on private land," depending on where each box is planted. So, is the charging station rollout between NY and MA the new Yankees vs. Red Sox? Nah, but a techie can dream.
Bomb-sniffing crystals may save us from nuclear Armageddon, tea leaves agree
Worried that a nuclear attack might wipe out all of American civilization? You needn't be, because the scientific community's crystal ball says crystal balls may save humanity. Last week, the Department of Energy awarded a $900,000 grant to Fisk University and Wake Forest, where researchers have been busy exploring the counter-terrorist capabilities of strontium iodide crystals. Once laced with europium, these crystals can do a remarkably good job of picking up on and analyzing radiation, as the team from Fisk and other national laboratories recently discovered. Cost remains the most imposing barrier to deploying the materials at airports or national borders, though soothsaying scientists claim it's only a matter of time before they develop a way to produce greater crystalline quantities at an affordable price. The only thing Miss Cleo sees is a glistening press release, in your very near, post-break future.
Shell opens America's first pipelined hydrogen-fueling station in Southern California
Residents of SoCal's Torrance should consider themselves lucky, as they're now living in America's first-ever city to have a pipelined hydrogen-fueling station. You can thank Shell and Toyota for picking up this government-funded green project. Sure, while the few other hydrogen stations still rely on delivery by supply truck (presumably running on diesel, ironically), this nevertheless marks a new milestone for our squeaky clean fuel, and it's only a matter of time before more stations get piped up to Air Products' hydrogen plants. If there's any indication of a time frame, Wired reminds us that 2015 should see the arrival of many new mass-market hydrogen cars from Toyota, Honda, and Mercedes-Benz. Not long to go now, fellow tree huggers.
Google helps electric car owners find battery charges, peace of mind
The biggest challenge of owning an electric vehicle aside from having to awkwardly pal around with Ed Begley Jr. all of the time? Finding a place to charge it, of course. The ever-green folks at Google have teamed up with the US Department of Energy and more than 80 companies to form the GeoEVSE Forum, an organization aimed at bringing diverse electric car resources under a single umbrella. Looking for one of those elusive Best Buy charging stations? Use the Google Maps database, helmed by the DOE, which currently offers some 600 alternative fueling stations, including electric charging, hydrogen, and natural gas. Now if only it could help us find a good deal on a Tesla.
TALON robot gets declawed, helps Japan sniff out radiation (video)
Robotics experts at the Department of Energy's Idaho National Laboratory just taught an old war machine some new tricks, namely radiation detection -- a timely acquisition of knowledge, for sure. Swapping out rocket launchers and machine guns for a suite of radiological sensors, digital cameras, and a GPS device, this modified TALON will be used to map the radiation levels (and create a visual output) surrounding the Fukushima nuclear power plant. The newly modified TALON landed in Japan just last week, joining an existing team of robot helpers already in use in the disaster area, including two additional TALONs equipped with sensors that can identify more than 7500 environmental hazards. Guns for Geiger counters seems like a good trade to us; check the video up top to watch the 'bot try out its treads. [Thanks, John]
AT&T and Verizon join National Clear Fleet Program, thumb their noses at petrol
Thought the Prez was just kidding about those alternative fuel initiatives? Think again. Just hours after stating that the US government fleet would be 100 percent alternative fuel, hybrid, or electric vehicles by 2015, Obama has announced the National Clean Fleets Partnership, an initiative of the Department's Clean Cities program. It's a rather unique public-private partnership, and it'll be assisting large companies to "reduce diesel and gasoline use in their fleets by incorporating electric vehicles, alternative fuels, and fuel-saving measures into their operations." A handful of Charter members have made themselves known, with AT&T, Verizon, FedEx, Pepsi-Co and UPS all committed to deploying over 20,000 advanced technology vehicles in the years to come -- an effort that should save over seven million gallons of fuel per year. Ma Bell in particular will be replacing over 15,000 rides with 7,000 hybrids and 8,000 compressed natural gas vehicles during the next decade, while Verizon looks to use a raft of cars (er, vans) that rely on biodiesel and ethanol. Whether or not such a program leads to the installation of more EV charging stations remains to be seen, but if it's good enough for Brown, surely it'll be good enough for your future Tesla. Vid's after the break, kiddos.
