    As the sustainable Juggernaut of fuel cell vehicles (FCV) powers ever forward, a group of scientists are cooking up ways to make the alternative energy source more durable and even cheaper. By combining graphene -- think pencil lead -- and indium tin oxide (ITO) nanoparticles, the team produced a catalytic material that is both stronger and more chemically active than the usual catalytic combo. Fuel cells typically use a chemical catalyst like platinum, sitting atop a base of black carbon or metal oxides, to break down oxygen and hydrogen gases, creating water in the process -- thing is, carbon is easily eroded by the resulting water, and metal oxides, while more stable, are less conductive. Using graphene -- which because of its porousness erodes less quickly -- in combination with the stable ITO and platinum nanoparticles, researchers have created what could be referred to as a super fuel cell -- a stronger, longer lasting, and potentially cheaper version of the alternative energy source. Unfortunately, without enough hydrogen filling stations, these super fuel cells won't come to anyone's rescue anytime soon.

    The President revealed his 2012 budget proposal today, including $853 million for nuclear energy research -- which includes development of "mini-nukes," or small, modular reactors that can be shipped and deployed relatively quickly, and built relatively cheaply (up to $2 billion, as opposed to the $10 billion price tag of your traditional reactor). But don't get excited -- you won't likely be able to get your own backyard reactor just yet. For the time being, they're to be placed in existing large-scale labs like the Oak Ridge National Laboratory in Tennessee. It is hoped that the reactors will bring a 28 percent reduction of the Energy Department's carbon footprint by 2020.

  • IBM's Mira supercomputer does ten petaflops with ease, inches us closer to exascale-class computing

    Say hello to the Blue Gene/Q, or if you're looking for something a bit less intimidating, "Mira." That's IBM's latest and greatest concoction, a ten-petaflop supercomputer capable of running programs at ten quadrillion calculations a second. Hard to say who'd win between Mira and Watson, of course, but there's absolutely no question who'd come out on top if Mira were pitted against her predecessor Intrepid (hint: Mira's 20x faster). To put this all in perspective, IBM's chiming in with this: "If every man, woman and child in the United States performed one calculation each second, it would take them almost a year to do as many calculations as Mira will do in one second." Mira's next stop is at the US Department of Energy's Argonne National Laboratory, where it'll be used to tackle 16 projects in particular that were drawn from a pool of proposals to gain access to her capabilities. We're told that these include a range of initiatives -- from reducing energy inefficiencies in transportation and developing advanced engine designs to spurring advances in energy technologies -- and in time, it could lead to exascale-class computers "that will be faster than petascale-class computers by a factor of a thousand." And here we are getting excited about a 5GHz Core i7.

  • Aptera: no production vehicles until we get funding, from the government or elsewhere

    Ah, funding. So necessary, yet so tedious to get. Aptera -- an automotive startup that has warmed our hearts with its eco-friendly, three-wheeled prototypes -- has been seeking government funding to take things "next level" ever since 2008. After being laughed out of the building at first, the company reapplied and managed to get its 2e certified as a "car" by the US Department of Energy. Unfortunately, miles (and miles) or red tape have held Aptera back ever since, and even today, they're still waiting to see if Uncle Sam will be shelling out to further their initiatives. Rather than putting its head down and realizing it's no GM, the company has pushed out a newsletter explaining the current situation. Essentially, it's dead-set on holding out for more funding -- be it from the DoE's coffers or elsewhere -- in order to maintain quality and keep the per-unit costs down to a reasonable level. According to Aptera: "We would obviously love to accelerate the process, but the government has to make sure they complete their comprehensive evaluation and we have to let the process run its course." Bummer.

  • Shell Oil pulls the plug on its last algae biodiesel research project

    Algae biodiesel has looked so promising (as in 100 times more fuel than corn or soy) that the U.S. Department of Energy gave $9 million to Cellana, a joint research venture between Shell Oil and HR Biopetroleum, specifically to look into the alternative energy source's prospects. It seems, however, that those prospects were no longer attractive to Shell, which has announced it will no longer pursue algae biodiesel, because it feels it doesn't have sufficient commercial viability. Partner HR Biopetroleum has stated it cannot continue the project on its own as Shell pursues other biofuel initiatives with other companies.

    Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green. This week at Inhabitat, we were thankful to be able to witness the long-awaited unveiling of the futuristic solar-powered Masdar Institute in Abu Dhabi, and we also heard the exciting news that scientists are developing a project that could have us using the Sahara desert to supply 50% of the world's energy by 2050. We were also dazzled by the dynamic "dancing" facade of the Kiefer Technic showroom and this towering greenery-lined pyramid caught our eye with its modern take on ancient Mayan architecture. The world of green tech had a lot to be grateful for too as the U.S. Department of Energy announced that it would award $19 million to modernize the national grid and green transportation saw the first flight powered by jatropha-based biofuel. On a lighter note, this solar-powered wheelchair and its designer prepared to embark on a 200 mile journey to showcase its capabilities. For those of you on the hunt for Cyber Monday deals, don't forget to check out our Green Gadget Gift Guide with our picks for the hottest eco-friendly tech out there. We also spotted this ingenious wood speaker system that amplifies music using the properties of the material it's made of and needs no electricity at all.

  • Melting silicon 'in reverse' can help purify it, result in cheaper electronics

    Just our favorite combination of news: a mind-bending innovation that can have a very practical impact on our daily tech consumption. MIT scientists have found that silicon -- when combined in the right dosage with other metals -- can actually be made to melt by reducing its temperature. Typically, you'd require 1,414 degrees of Celsius heat to liquidize solid silicon, but the intermixed variant discussed here need only reach 900 degrees before its slow cooling process starts turning it gooey. The great advantage to this discovery is that because the impurities tend to separate off into the liquid part, there's now a practicable way to filter them out, meaning that things like solar cells won't require the same high grade of silicon purity for their construction -- which in turn might lead to us being able to afford them one day. Of course, that's getting way too far ahead of ourselves, as the research is still ongoing, but good news is good news no matter the timescale.

  • DoE forecasts far cheaper, lighter, longer-lasting EV batteries by 2015

    Dippin' in a Tesla is an expensive proposition, as we're sure you're well aware, but the US Department of Energy seems certain the cost of electric vehicles -- or at least their all-important rechargeable batteries -- will come down to reasonable levels. The government estimates a stack of cells good for 100 miles will drop to $10,000 by the end of 2015, and that 40-mile batteries for PHEVs will sink to $4,000 in the same timeframe -- both around one-third of what the containers presently cost. On the physical front, portly packages of Li-ion presently weigh 333kg (about 734 pounds) per 100 miles of range, but are expected to slim down to 222kg (489 pounds) by 2015, and shed weight precipitously in following years. Like any weather forecast, the figures are subject to the prevailing wind, but it's looking like average Americans may one day have use for all those free charging stations.

  • Coulomb partners with Ford, Chevy, Smart to deliver 4,600 free EV charging stations in US

    Looks like Australia and Poland were just the beginning: Coulomb Technologies is looking to roll out nearly 5,000 electric vehicle charging stations in the US, effective immediately. If one of those cherry-red push pins is pointed at your neighborhood, you'll likely see the stations popping up at local businesses soon, and if you're looking to purchase a Chevy Volt, Tesla-powered Smart or one of Ford's two new EVs, you can even qualify to have a free station installed in your home. Partially paid for by a $15 million grant from the Department of Energy, the ChargePoint America program won't necessarily give you free electricity to go with it -- that "charge" in ChargePoint has a double meaning, after all -- but we're happy to see the zero-emissions future is finally on a roll. PR after the break.

  • EnergyStar program certifies 'gasoline-powered alarm,' other imaginary abominations

    It'd be pretty difficult for you to reach Engadget without having seen the EnergyStar logo on something along your way here. Whether it was as part of your motherboard's bootup sequence or on the box of your new TFT monitor, EnergyStar certification has become a de facto standard for most electronics being manufactured nowadays. What you might not have known -- but probably could have guessed -- is that the process for obtaining that sticker is far from bulletproof. The American Government Accountability Office has recently done a bit of spy work by putting forward imaginary products and false claims to the validating authority, and regrettably found its bogus items "mostly approved without a challenge." The auditors' conclusion was that the program is "highly vulnerable to fraud," and the stuff they've had certified would seem to corroborate that verdict. Hit up the Times article for the full story of governmental incompetence while the Department of Energy -- the body responsible for running the program -- tries to get its act straightened out.

  • Fluidic Energy promises better, cheaper metal-air batteries, wins DoE grant

    It's not the only company working on metal-air batteries, but Scottsdale, Arizona-based Fluidic Energy may be in a better position to deliver on its promises than most, as it's just managed to snag a $5.13 million research grant from the US Department of Energy to further develop the "breakthrough" technology. While that word's thrown around quite a bit these, in the case, it may actually live up to the hype, considering that breakthrough in question would be a battery that's able to deliver eleven times the energy density of the best lithium-ion batteries for less than one-third of the cost. The key to that, it seems, is the battery's use of an ionic liquid as its electrolyte, which is described as a "wonder fluid" since it's able to last significantly longer than other fluids because drying out isn't a problem, and because it brings with it a significant boost in energy density. Of course, the company still apparently doesn't have an actual battery to back up its claims just yet, and it's not making any promises about when it might deliver one either.

  • Aptera 2e three-wheeler deemed a car by the DoE, eligible for funding

    For a time, it looked Aptera might be missing out on the US Department of Energy's funding bonanza for energy-efficient vehicles due to its car's three-wheeled nature, but it looks like President Obama has now had the final say on the matter, and signed legislation that makes both two-wheeled and three-wheeled vehicles eligible for the same funding as their four-wheeled counterparts. Of course, that doesn't yet mean that Aptera will actually receive any funding, and the legislation doesn't have anything to do with safety regulations, where the 2e is still classified as a motorcycle by the Department of Transportation. For its part, however, Aptera says that it'll be filing another application to meet the updated requirements, and it still insists that it'll hit "volume production" of the car sometime in 2010, and get it on the road for between $25,000 and $40,000.

  • Department of Energy lends Fisker $528.7 million for Karma and Project Nina

    Well, it seems like that sex-on-wheels advert has done its job. Fisker's development of the oh so desirable Karma PHEV and its lower-cost sibling, now known as Project Nina (inspired by Christopher Columbus' escape from the Old World, no less), has been given a significant boost by the US government. Henrik Fisker himself has been quoted as saying that once the conditional loan is in, "it wouldn't take long to get the lower-cost plug-in hybrid on the road." If the company carries over the aggressive styling from the luxury model, it might have a real winner on its hands, though -- we know -- it's got to be cheap enough first. While waiting for that $528.7 million to work its magic, you can gawk at the solar paneled roof on the Karma, to be found after the break.

  • Tesla, Ford, Nissan all receive electric car development loans from US government

    High five, Tesla fans -- everyone's favorite incredibly controversial electric car company has just been granted $465m in loans from the Department of Energy's Advanced Technology Vehicle Manufacturing program. The bulk of the money will go towards that postponed Model S factory, while the remaining $100m will be used to fund an electric powertrain manufacturing facility that will sell parts like motors and battery packs to other carmakers. Tesla wasn't the DOE's only big winner: Nissan received $1.6b (billion!) to build batteries and EVs in Tennessee and Ford received an undisclosed amount to build two upcoming electric cars, but since those companies have largely drama-free upper management that isn't constantly involved in lawsuits, it feels a little more routine. Still, it's an exciting time -- let's hope all these tax dollars turn into affordable, convenient electric transportation sooner rather than later.Update: A "congressional source" has told the AP that Ford's getting $5.9 billion, so yeah, the Oval's still the big dog.

  • Researchers create nanotube memory that can store data for a billion years

    Researchers at the Department of Energy's Lawrence Berkeley National Laboratory and UC Berkeley have developed an ultra-dense memory chip that is capable of storing data for up to a billion years (besting silicon chips by roughly... a billion years). Consisting of a crystalline iron nanoparticle shuttle encased within a multiwalled carbon nanotube, the device can be written to and read from using conventional voltages already available in digital electronics today. The research was led by Alex Zettl, who notes that current digital storage methods are capable of storing mass amounts of data, but last just decades, while, say, some books have managed to last nearly a thousand years, though the amount of data they contain is quite small. The new method, called shuttle memory, is based on the iron nanoparticle which can move back and forth within the hollow nanotu. Zettl believes that, while shuttle memory is years away from practical application, it could have a lot of archival applications in the future. There's a video after the break, hit the read link for more tiny details.[Via The Register]

  • Sprint nabs $7.3M grant for hydrogen fuel cells at cell sites

    The US Department of Energy is feeling generous with some $41.9 million worth of cold, hard cash in a round of grants aimed at advancing fuel cell tech, and Sprint ended up scoring some $7.3 million of it -- the only carrier to do so. Carriers and hydrogen fuel cells don't seem like a natural fit at first, but it turns out that backup power at cell sites is kind of a big deal, and fuel cells are a perfect fit for a reliable, long-running, zero-emission solution. Interestingly, Sprint has been really into this for a while now -- it's their third awarded grant, and it turns out that they've had fuel cells deployed at sites since way back in 2005 (and they've even got 12 patents under their belt to prove it). Most current sites offer up to 15 hours of power in the event of an emergency using low-pressure hydrogen tanks, and the carrier says that it'll use the latest cash infusion to work with its partners to boost that up to 72 hours. Probably worse ways for the government to spend $7.3 million, when you think about it (say, on no-bid contracts for surplus eraser heads for Number 2 pencils, for instance).

  • US Department of Energy pours $30 million into plug-in hybrids

    While some automakers are already promising to have plug-in hybrids on the road by 2010, the US Department of Energy is now pouring some cash into a slightly less ambitious joint effort with Ford, General Motors, and General Electric, which would see plug-ins capable of driving 40 miles on a single charge roll out by 2014. Under the new effort, General Motors will be tasked with improving lithium-Ion battery packs and charging systems, and integrating them into its own research with a test fleet by 2011, while Ford will be aiming to speed up the mass-production of plug-in hybrids, as well as improve its batteries and build prototype vehicles. Rounding things out, General Electric will be partnering with Chrysler to develop a dual-battery system, which promises to let vehicles travel 40 miles on a charge. All of that is still subject to appropriations by Congress, however, and the aforementioned companies would obviously be pouring in a good chunk of change themselves, as a mere $30 million isn't exactly quite enough to shake up the auto sector these days.

    This summer, teams of college students have amassed on their school campuses to create solar-only, off-the-grid, self-powered homes, which will eventually compete in Washington D.C. for the Department of Energy's 2007 Solar Decathlon. To build the houses, students are limited to currently available, off-the-shelf technologies, and must also focus on design, comfort, and market viability. The groups will move their eco-friendly homes to the National Mall in D.C., where the "solar village" of houses will be open for touring by the general public, and will be scored by judges for architecture, engineering, and energy balance, amongst others. The whole shebang is sponsored by heavy-hitters like Sprint and BP, but it's unclear whether the winning team receives prizes beyond the knowledge that their solar home crushed the others in head-to-head combat.[Via CNET]

  • IBM pushing vertical stacking in next wave of supercomputers

    Next-generation cooling technology isn't the only thing IBM's R&D crew is spending time with, as the chip giant has recently made plans to hit up "vertical stacking technology" in order to make the next wave of supercomputers really crank. Supposedly, "laying chips vertically -- as opposed to side by side -- reduces the distance data has to travel by 1,000 times, making the chips faster and more efficient." The new format will place chips directly atop one another and connect them with "tungsten filled pipes etched through the silicon," which will subsequently eliminate the need for wires and increase the speed at which data can flow. The questionably-dubbed "3D chips" will reportedly operate around 40-percent more efficiently than existing renditions, and considering that Intel is purportedly cooking up a similar agenda in their own labs, that "end of 2007" release date is quite likely to be accurate.

  • Solar cell breakthrough: 40% efficiency achieved

    If that silly Hummer O2 concept vehicle we just saw didn't sate your appetite for environmental friendliness, try this on for size: researchers at Boeing-Spectrolab have just succeeded in building a multi-junction solar cell that achieves an incredible 40.7% efficiency, or -- to the best of our knowledge -- about twice that of the reigning champ in this space. To put this Department of Energy-backed breakthrough in perspective, it was less than two months ago that Silicon Valley-based SunPower announced a 22% efficient cell, and even that model was claimed to produce 50% more power over a given space than previous iterations. In case you're unfamiliar with multi-junction cells -- no shame in that game -- they can best be described as being composed of several layers, with each slice capturing only a portion of the solar spectrum; this method of optical concentration is what has allowed cells to surpass the 12% to 18% efficiency barrier faced by most traditional modules. In conclusion, while this is certainly an encouraging development, we remain somewhat skeptical about its potential for real-world implementation: once Big Oil gets wind of this new tech, it will likely "disappear" just as quickly as that guy who invented a car that runs on water, man.[Via Slashdot]
