The Hanford Vit Plant in Washington state, a $17 billion federal facility for treating and immobilizing radioactive waste, is now on track to begin "glassifying" low-activity nuclear waste as soon as 2022, reports IEEE Spectrum. This is "a year ahead of a court-mandated deadline." From the report: Still, an air of uncertainty surrounds the project. The U.S. Department of Energy (DOE) has proposed reclassifying some of the nation's radioactive waste as less dangerous, and it's unclear how that could affect the Hanford facility's long-term prospects. Hanford houses about 212 million liters of high-level waste, the leftovers of the U.S. nuclear weapons program.

However, higher-level waste has a longer timeline. Separate pretreatment and vitrification facilities aren't slated for commissioning until 2033. All parts of the Vit Plant are legally required to begin fully operating by 2036, under a consent decree between Washington, Oregon, and the federal government. The DOE hasn't said whether, or how, its proposal to reclassify nuclear waste would affect existing plans at Hanford if adopted. The agency is not making any decisions on the classification or disposal of any particular waste stream at this time, a DOE official said by email. [...] Though current law defines high-level radioactive waste as the sludge that results from processing highly radioactive nuclear fuel, the DOE is considering slapping a new, potentially less expensive label on it if it can meet the radioactive concentration limits for Class C low-level radioactive waste. Reclassifying nuclear waste would allow the federal government to sidestep decades of cleanup work, saving it billions of dollars. The relabeling might even enable the DOE to bypass costly vitrification and instead contain tank waste by covering it with concrete-like grout, as the agency does at other decommissioned nuclear sites. Officials and citizens in Washington and Oregon oppose this method for Hanford, "citing the risk of long-term soil and groundwater contamination and the challenges of moving and storing voluminous grout blocks," reports IEEE Spectrum. "Earlier federal studies found that grout 'actually performed the worst of all the supplemental treatment options considered.' (A 2017 report to Congress, however, suggested both vitrification and grout could effectively treat Hanford's low-activity waste.)"

An anonymous reader quotes a report from Ars Technica: An energy development group has been working for years to put together Ohio's first offshore wind project. That might sound odd for a state so far from the sea, but the benefits of offshore wind (strong, consistent gusts and relative proximity to major population centers) translate to wind turbines that are placed in freshwater, too. Consequently, an area eight miles off Ohio's Lake Erie coastline is slated to see six new 3.45 megawatt (MW) turbines as part of a 20.7MW pilot installation. On Thursday, the Department of Energy (DOE) issued an Environmental Assessment stating that proceeding with the plan would not cause any "impact to the human environment." In an additional finding published by the DOE this week, the department added that it did not believe that the offshore wind project would cause significant damage to migratory birds, either. Finally, the DOE proposed an unspecified amount of funding for the project, which will be the first freshwater offshore wind project in the US and one of the first offshore wind projects overall. The Lake Erie Energy Department Corporation (LEEDCo) and Norwegian investor Fred Olsen Renewables (FOR) will be developing the "Icebreaker" project, as the turbine installation has been called. "Interestingly, the turbines will be secured to the lake using a 'Mono Bucket' foundation, with a suction-based design that's similar to what's been used on offshore oil-drilling platforms in the North Sea," reports Ars. "The design, LEEDCo says, uses 'the best and lowest-cost technology for sites 25 meters and less.'"

"French train-building company Alstom built two hydrogen-powered trains and delivered them to Germany last weekend, where they'll zoom along a 62-mile stretch of track that runs from the northern cities of Cuxhaven, Bremerhaven, Bremervorde, and Buxtehude," reports Ars Technica. "The new trains replace their diesel-powered counterparts and are the first of their kind, but they are likely not the last. Alstom is contracted to deliver 14 more hydrogen-powered trains, called Coradia iLint trains, before 2021." From the report: The trains are an initial step toward lowering Germany's transportation-related emissions, a sector that has been intractable for policy makers in the country. But hydrogen fuel faces some chicken-and-egg-type problems. Namely, hydrogen is difficult to store, and making it a truly zero-emissions source of fuel requires renewable electricity to perform water electrolysis. The more common option for creating hydrogen fuel involves natural gas reforming, which is not a carbon-neutral process.

The advantages of hydrogen fuel cells are that -- unlike battery-powered vehicles -- refueling a hydrogen-powered vehicle is just as fast as a vehicle powered by fossil fuels. No sitting around and charging overnight is required. Trains tend not to be battery-powered when they're electric, however, because they're so heavy. Electric train systems tend to use catenary systems, with electrified cables providing electricity to the train. But over long distances, setting up an external electricity source can be expensive. Both trains have a reported range of 1,000km (621 miles) and can reach top speeds of 140km/h (87mph). Cost is unknown, although Alstom's press release says that Lower Saxony, the German state where the trains will run, supported the purchase of the 14 additional trains with $94.5 million.

An anonymous reader quotes a report from Ars Technica: According to reports from Bloomberg and E&E News, the Trump Administration has been exploring another way to help coal and nuclear generators: the Defense Production Act of 1950. The Act was passed under President Truman. Motivated by the Korean War, it allows the president broad authority to boost U.S. industries that are considered a priority for national security. On Thursday, E&E News cited sources that said "an interagency process is underway" at the White House to examine possible application of the act to the energy industry. The goal would be to give some form of preference to coal and nuclear plants that are struggling to compete with cheap natural gas.

If the DOE decides not to invoke Section 202(c), the president may turn to the Defense Production Act. According to a 2014 summary report (PDF) from the Congressional Research Service (CRS), the act would allow the president to "demand priority for defense-related products," "provide incentives to develop, modernize, and expand defense productive capacity," and establish "a voluntary reserve of trained private sector executives available for emergency federal employment," among other powers. (Some even more permissive applications of the Act were terminated in 1957.) Using the Act to protect coal and nuclear facilities would almost certainly be more controversial, as the link between national defense and keeping uneconomic coal generators running is not well-established. The Administration could apply the Act to "provide or guarantee loans to industry" for material-specific deliveries and production. "The president may also authorize the purchase of 'industrial items or technologies for installation in government or private industrial facilities,'" reports Ars.

Orome1 shares a report from Help Net Security: Today, the Department of Energy (DOE) is announcing awards of up to $50 million to DOE's National Laboratories to support early stage research and development of next-generation tools and technologies to further improve the resilience of the Nation's critical energy infrastructure, including the electric grid and oil and natural gas infrastructure. The electricity system must continue to evolve to address a variety of challenges and opportunities such as severe weather and the cyber threat, a changing mix of types of electric generation, the ability for consumers to participate in electricity markets, the growth of the Internet of Things, and the aging of the electricity infrastructure. The seven Resilient Distribution Systems projects awarded through DOE's Grid Modernization Laboratory Consortium (GMLC) will develop and validate innovative approaches to enhance the resilience of distribution systems -- including microgrids -- with high penetration of clean distributed energy resources (DER) and emerging grid technologies at regional scale. The project results are expected to deliver credible information on technical and economic viability of the solutions. The projects will also demonstrate viability to key stakeholders who are ultimately responsible for approving and investing in grid modernization activities. In addition, the Department of Energy "is also announcing 20 cybersecurity projects that will enhance the reliability and resilience of the Nation's electric grid and oil and natural gas infrastructure through innovative, scalable, and cost-effective research and development of cybersecurity solutions."

New submitter joshtops shares a report from Scientific American: As NASA makes plans to one day send humans to Mars, one of the key technical gaps the agency is working to fill is how to provide enough power on the Red Planet's surface for fuel production, habitats and other equipment. One option: small nuclear fission reactors, which work by splitting uranium atoms to generate heat, which is then converted into electric power. NASA's technology development branch has been funding a project called Kilopower for three years, with the aim of demonstrating the system at the Nevada National Security Site near Las Vegas. Testing is due to start in September and end in January 2018. The last time NASA tested a fission reactor was during the 1960s' Systems for Nuclear Auxiliary Power, or SNAP, which developed two types of nuclear power systems. The first system -- radioisotope thermoelectric generators, or RTGs -- taps heat released from the natural decay of a radioactive element, such as plutonium. RTGs have powered dozens of space probes over the years, including the Curiosity rover currently exploring Mars. The second technology developed under SNAP was an atom-splitting fission reactor. SNAP-10A was the first -- and so far, only -- U.S. nuclear power plant to operate in space. Launched on April 3, 1965, SNAP-10A operated for 43 days, producing 500 watts of electrical power, before an unrelated equipment failure ended the demonstration. The spacecraft remains in Earth orbit.

An anonymous reader quotes a report from Yahoo: Scientists at Oak Ridge National Laboratory in Tennessee have developed a dryer that could make doing laundry much quicker. Called the ultrasonic dryer, it's expected to be up to five times more energy efficient than most conventional dryers and able dry a large load of clothes in about half the time. Instead of using heat the way most dryers do, the ultrasonic dryer relies on high-frequency vibrations. Devices called green transducers convert electricity into vibrations, shaking the water from clothes. The scientists say that this method will allow a medium load of laundry to dry in 20 minutes, which is significantly less time than the average 50 minutes it takes in many heat-based machines. The drying technology also leaves less lint behind than normal dryers do, since the majority of lint is created when the hot air stream blows tiny fibers off of clothing. Drying clothes without heat also reduces the chance that their colors will fade. While the ultrasonic dryer has been in development for the past couple of years, the U.S. Department of Energy explains in a published video that it has recently been "developed into a full-scale press dryer and clothes dryer drum -- setting the stage for it to one day go to market through partners like General Electric Appliances."

Solar energy now accounts for 43% of the workers in the U.S. power-generating industry, surpassing the 22% from all workers in the coal, oil, and gas industries combined, according to new figures from the Department of Energy. Slashdot reader Lucas123 writes: In 2016, the solar workforce in the U.S. increased by 25% to 374,000 employees, compared to 187,117 electrical generation jobs in the coal, gas and oil industries... [N]et power generation from coal sources declined by 53% between 2006 and September 2016; electricity generation from natural gas increased by 33%; and solar grew by over 5,000% -- from 508,000 megawatt hours (MWh) to just over 28 million MWh.
Solar industry created jobs at a rate 20 times faster than the national average, according to the Energy Department, while 102,000 more workers also joined the wind turbine industry last year, a 32% increase. In fact, 93% of the new power in America is now coming from solar, natural gas, and wind -- but it's building out new solar-generating capacity that's causing much of the workforce increases, according to the Energy Department. "The majority of U.S. electrical generation continues to come from fossil fuels," their report points out, adding that the latest projections show that will still be true in the year 2040.

"The world's next energy revolution is probably no more than five or ten years away," reports The Telegraph. "Cutting-edge research into cheap and clean forms of electricity storage is moving so fast that we may never again need to build 20th Century power plants in this country..." Slashdot reader mdsolar quotes their article: The US Energy Department is funding 75 projects developing electricity storage, mobilizing teams of scientists at Harvard, MIT, Stanford, and the elite Lawrence Livermore and Oak Ridge labs in a bid for what it calls the "Holy Grail" of energy policy. You can track what they are doing at the Advanced Research Projects Agency-Energy (ARPA-E). There are plans for hydrogen bromide, or zinc-air batteries, or storage in molten glass, or next-generation flywheels, many claiming "drastic improvements" that can slash storage costs by 80pc to 90pc and reach the magical figure of $100 per kilowatt hour in relatively short order.

"Storage is a huge deal," says Ernest Moniz, the U,S. Energy Secretary and himself a nuclear physicist. He is now confident that the U.S. grid and power system will be completely "decarbonized" by the middle of the century.
One energy consultant predicts the energy storage market will be worth $90 billion in 2025 -- 100 times larger than it is today.

mdsolar writes: The Department of Energy is formally launching its initiative aimed at establishing a disposal site for spent nuclear fuel. The department said Monday that it is accepting input on the disposal plan, which centers on finding at least one place to store spent fuel, with the consent of the local community. Officials are also planning forums throughout 2016 to inform a more concrete plan for establishing a disposal site. It's a key step toward rolling out what the Obama administration thinks is the best way forward for nuclear waste disposal. It stands in stark contrast to the proposed Yucca Mountain nuclear waste repository in Nevada, which was designated by Congress to be the country's main waste site, but which the Obama administration canceled amid strong local and state opposition to it.

Kristine Lofgren writes: The SURE HOUSE, designed and built by the Stevens Institute of Technology, was announced today as the winner of the 2015 Solar Decathlon. The uber-efficient house exceeds Passive House standards and uses less than 10-percent of the energy that a standard house consumes. But beyond solar-powered efficiency, the house is also designed to be open and breezy when the weather is good, but when a hurricane strikes, the house can be locked tight against the onslaught. In fact, it's so tough that it can act as a solar powered community center for an area hit by a natural disaster. Congratulations to the SURE HOUSE team! The team's website has some additional pictures, as well as more explanation of their design decisions.

They detail new technology that can reach higher into the sky to capture more energy and more powerful turbines to generate more gigawatts. These new turbines are 110-140 meters tall, with blades 60 meters long. The Energy Department forecasts strong, steady growth of wind power across the country, both on land and off shore.

Right now, wind provides the nation with about 4.5 percent of its power. But an in-depth DOE report (PDF) released yesterday forecasts that number will rise to 10 percent by 2020—then 20 percent by 2030, and 35 percent by 2050.

HughPickens.com writes The LA Times reports that Los Alamos National Security, the contractor managing the nuclear weapons laboratory at Los Alamos, NM has been slapped with a $57-million reduction in its fees for 2014, largely due to a costly nuclear waste accident in which a 55-gallon drum packaged with plutonium waste from bomb production erupted after being placed in a 2,150-foot underground dump in the eastern New Mexico desert. Casks filled with 3.2 million cubic feet of deadly radioactive wastes remain buried at the crippled plant and the huge facility was rendered useless. The exact causes of the chemical reaction are still under investigation, but Energy Department officials say a packaging error at Los Alamos caused a reaction inside the drum. The radioactive material went airborne, contaminating a ventilation shaft that went to the surface giving low-level doses of radiation to 21 workers. According to a DOE report, the disaster at WIPP is rooted in careless contractors and lack of DOE oversight (PDF). "The accident was a horrific comedy of errors," says James Conca, a scientific advisor and expert on the WIPP. "This was the flagship of the Energy Department, the most successful program it had. The ramifications of this are going to be huge. Heads will roll."

The accident is likely to cause at least an 18-month shutdown and possibly a closure that could last several years. Waste shipments have already backed up at nuclear cleanup projects across the country, which even before the accident were years behind schedule. According to the Times, the cost of the accident, including likely delays in cleanup projects across the nation, will approach $1 billion. But some nuclear weapons scientists say the fine is an overreaction. "It was a mistake by an individual — a terrible mistake — and Washington now wants to punish a lot of people," says Conca. "The amount of radiation that was released was trivial. As long as you don't lick the walls, you can't get any radiation down there. Why are we treating this like Fukushima?"

The modern electronics industry relies on inputs and supply chains, both material and technological, and none of them are easy to bypass. These include, besides expertise and manufacturing facilities, the actual materials that go into electronic components. Some of them are as common as silicon; rare earth minerals, not so much. One story linked from Slashdot a few years back predicted that then-known supplies would be exhausted by 2017, though such predictions of scarcity are notoriously hard to get right, as people (and prices) adjust to changes in supply. There's no denying that there's been a crunch on rare earths, though, over the last several years. The minerals themselves aren't necessarily rare in an absolute sense, but they're expensive to extract. The most economically viable deposits are found in China, and rising prices for them as exports to the U.S., the EU, and Japan have raised political hackles. At the same time, those rising prices have spurred exploration and reexamination of known deposits off the coast of Japan, in the midwestern U.S., and elsewhere.

Alex King is director of the Critical Materials Institute, a part of the U.S. Department of Energy's Ames Laboratory. CMI is heavily involved in making rare earth minerals slightly less rare by means of supercomputer analysis; researchers there are approaching the ongoing crunch by looking both for substitute materials for things like gallium, indium, and tantalum, and easier ways of separating out the individual rare earths (a difficult process). One team there is working with "ligands – molecules that attach with a specific rare-earth – that allow metallurgists to extract elements with minimal contamination from surrounding minerals" to simplify the extraction process. We'll be talking with King soon; what questions would you like to see posed? (This 18-minute TED talk from King is worth watching first, as is this Q&A.)

Five years ago today, we mentioned here what was characterized as "The Great Ethanol Scam." According to the central story in that post, the ethanol in gasoline was (or would be) "destroying engines in large numbers," and the only real winners with a rise in the use of ethanol as a gasoline supplement would be auto mechanics. An increasing number of cars are officially cleared for use with E15 (15 percent ethanol), and a growing number of E85 vehicles are in the wild now, too, though apparently many of their owners don't realize that their cars can burn a mixture that's mostly ethanol. When I can, I fill my car with no-ethanol gas, but that's not very easy to find (farmer's co-ops are one handy source), so most of my driving over the past decade has been with E10 fuel. I seem to get better mileage with all-gas, but the circumstances haven't been controlled enough to make a good comparison. What has your experience been? Have you experienced ethanol-related car problems, or were the predictions overblown?

Daniel_Stuckey writes "With funding from the Bill and Melinda Gates Foundation's Reinvent the Toilet challenge, [a] team has developed a toilet that uses concentrated solar power to scorch and disinfect human waste, turning feces into a useful byproduct called biochar ... a sanitary charcoal material that is good for soils and agriculture. By converting solid waste to biochar (liquid waste is diverted elsewhere, as it's easier to deal with), the toilet thus allows for sanitary waste disposal without huge infrastructure investments. The toilet itself, called the Sol-Char, is a fascinating bit of engineering. In order to sanitize waste without the help of massive treatment facilities, Linden's team instead designed the toilet to scorch waste in a chamber heated by fiber optic cables that pipe in heat from solar collectors on the toilet's roof. 'A solar concentrator has all this light focused in on one centimeter. It'd be fine if we could bring everyone's fecal waste up to that one point, like burning it with a magnifying glass,' Linden said. 'But that's not practical, so we were thinking of other ways to concentrate that light.'"

An anonymous reader writes "Today Steven Chu, U.S. Secretary of Energy, released a letter indicating he won't continue to hold the job for President Obama's second term. He'll continue until the ARPA-E Summit at the end of February, and then perhaps a bit longer until a replacement is found. MIT's Technology Review sums up his contributions thus: 'Under his leadership, the U.S. Department of Energy has changed the way it does energy research and development. He leaves behind new research organizations that are intently focused on solving specific energy problems, particularly the Advanced Research Projects Agency for Energy as well as several Innovation Hubs. The latter were modeled closely on Chu's experience working at the legendary Bell labs, where researchers solving basic problems rubbed shoulders with engineers who knew how to build things. At one Innovation Hub, for example, researchers who are inventing new materials that can absorb sunlight or split water are working together with engineers who are building prototypes that could use those materials to generate fuel from sunlight. Chu also brought an intense focus on addressing climate change through technical innovation, speaking clearly and optimistically about the potential for breakthroughs to change what's possible.'"

theodp writes "On September 13, 2010, President Obama called A123 Systems from the Oval Office to congratulate them on opening the nation's first manufacturing facility to mass-produce electric vehicle batteries, which the White House noted was made possible by a $249 million Recovery Act grant the company received the prior August. 'When folks lift up their hoods on the cars of the future,' the President said, 'I want them to see engines and batteries that are stamped: Made in America. And that's what you guys are helping to make happen.' But on Saturday, the assets of A123 Systems were auctioned off to the Wanxiang Group, a large Chinese auto parts maker. Wanxiang agreed to pay $256 million for A123's automotive and commercial operations, including its three factories in the United States. Forbes reports that A123's stock, which closed at 7 cents a share on Friday, is now worthless."

Lasrick writes "Private security contractors strike again, this time at the Y-12 National Security Complex. A nun, a gardener, and a housepainter cut through three security fences to find themselves 20 feet away from highly dangerous nuclear material. And of course, only one guard has been fired (the one who arguably acted the bravest and did the right thing). A Department of Energy report (PDF) on the incident found 'troubling displays of ineptitude in responding to alarms, failures to maintain critical 2 security equipment, over reliance on compensatory measures, misunderstanding of security protocols, poor communications, and weaknesses in contract and resource management.' The contractors have been put on notice, (PDF), but they still have the contracts."

Nuclear fusion power is the process of fusing light nuclei together to release energy, and ultimately, to put electricity on the grid. Today, we have six researchers from MIT's Plasma Science and Fusion Center here to answer your questions about fusion power, tokamaks, and public support and funding in the U.S. for this research. The Obama Administration's budget request for fiscal year 2013 is paying for the U.S. share of ITER construction out of the domestic program, starting with the closure of the MIT fusion lab. The interviewees are ready to answer technical and policy questions, so don't be shy! And, as always, please break unrelated questions into separate posts. Read on for information about the researchers who will answer your questions. Dr. Martin Greenwald is a Senior Scientist and Associate Director of the MIT Plasma Science and Fusion Center. His experimental work focuses on turbulence and transport, density limits, and pellet fueling of magnetically confined plasmas. More recently, Dr. Greenwald has been heavily involved with data management, computation, simulation, networks, and remote collaborations for fusion research.

Professor Ian Hutchinson is interested in plasma control in tokamaks, as well as spatially resolved measurements of the radiated power coming from the plasma. He is the author of the standard fusion textbook Principles of Plasma Diagnostics. Prof. Hutchinson also works on particle-in-cell simulations of astrophysical and laboratory plasmas.

Assistant Professor Anne White researches turbulence phenomena on the Alcator C-Mod tokamak, developing new diagnostics to resolve the small fluctuations which cause energy and particles to leak out. She is the recent recipient of the U.S. Department of Energy Early Career Award.

Professor Dennis Whyte pursues research into plasma–material interactions; that is, the way the hot plasma in a magnetic fusion reactor interacts with the surrounding solid materials walls. His team is also developing novel diagnostics for fusion nuclear science, which is critical as fusion reactors start producing power (and neutrons) over long periods of time.

Nathan Howard and Geoff Olynyk are Ph.D students on the Alcator C-Mod project. Nathan, who is in the final year of his studies, studies turbulent transport phenomena experimentally and through simulation. Geoff, in his fourth year, is working on disruption mitigation, which is a way to quickly and safely shut a tokamak plasma down in a few thousandths of a second.

Hugh Pickens writes "Brian Wingfield writes in Bloomberg that the Blue Ribbon Commission on America's Nuclear Future has sent a draft report to Energy Secretary Steven Chu recommending that US communities should be encouraged to vie for becoming a federal nuclear-waste site as a way to end a decades-long dilemma over disposing of spent radioactive fuel and says this 'consent-based' approach will help cut costs and end delays caused when the federal government picks a site over the objections of local residents, 'This means encouraging communities to volunteer (PDF) to be considered to host a new nuclear-waste management facility,' says the commission. Chu named the panelists after Obama canceled plans to build a permanent repository at Nevada's Yucca Mountain after the Yucca site was opposed by politicians from the state. 'The United States has traveled nearly 25 years down the current path only to come to a point where continuing to rely on the same approach seems destined to bring further controversy, litigation, and protracted delay,' says the report. The Blue Ribbon Commission cited as a 'success' the US Waste Isolation Pilot Plant near Carlsbad, New Mexico, which has accepted and disposed of some defense-related nuclear waste for more than a decade demonstrating that that 'nuclear wastes can be transported safely over long distances and placed securely in a deep, mined repository.' With the right incentives, 'there will be a great deal of support' for a waste site near the New Mexico facility, says former Senator Pete Domenici."

Reader Dr.Who notes that an Australian research team using IBM's Blue Gene/P supercomputer has calculated the sixty-trillionth binary digit of Pi-squared, a task which took several months of processing. Snipping from the article, the Dr. writes: "'A value of Pi to 40 digits would be more than enough to compute the circumference of the Milky Way galaxy to an error less than the size of a proton.' The article goes on to cite use of computationally complex algorithms to detect errors in computer hardware. The article references a blog which has more background. Disclaimers: I attended graduate school at U.C. Berkeley. I am presently employed by a software company that sells an infrastructure product named PI."

coondoggie writes "The US government today took a bold step toward perhaps finally getting some offshore wind energy development going with $50 million in investment money and the promise of renewed effort to develop the energy source. The plan focuses on overcoming three key challenges (PDF) that have made offshore wind energy practically non-existent in the US: the relatively high cost of offshore wind energy; technical challenges surrounding installation, operations, and grid interconnection; and the lack of site data and experience with project permitting processes."

coondoggie writes "The White House has outlined a wide-ranging plan for putting one million of what it calls 'advanced technology vehicles' on the road by 2015. Most observers would say that is a good start, but is it reasonably doable? The next White House budget will include a number of investments and enticements to make the goal achievable in theory. Of course, not all of the provisions are likely to make the cut."

coondoggie writes "The Department of Energy wants to kick up the research and development of offshore wind projects as it looks to achieve its goal of producing 20% of the country's electricity from wind farms by 2030. The DOE Wind Program is looking to focus on what it calls specific advanced technology, gigawatt-scale demonstration projects that can be carried out by partnerships with a wide range of eligible organizations and stimulate cost-effective offshore wind energy deployment in coastal and Great Lakes regions of the country. The agency is also looking for more research that can help address market barriers in order to facilitate deployment and reduce technical challenges facing the entire industry, as well as technology that will reduce cost of offshore wind energy through innovation and testing."

coondoggie writes "The US Department of Energy this week opened an online portal where the public can get all the technical details it can stomach about the BP oil disaster in the Gulf. The DoE site offers online access to schematics, pressure tests, diagnostic results and other data about the malfunctioning blowout preventer and other problems in the ongoing mess. This comes alongside news that the US Coast Guard has issued a call for better specialized technology to help it respond to the ever-widening spill. The Coast Guard is looking for all manner of technology, such as advanced wireless sensors to help it track the movement and amount of oil in the Gulf, or devices that could help to contain and control the underwater leak." Reader freddled points out a story at the Guardian that illustrates how the location of an oil leak is frequently the primary factor in its perceived importance.

An anonymous reader writes "'The blind will see again,' could be the motto of the Artificial Retina Project, which is getting ready to implant a 60-pixel artificial retina chip into 10 blind patients later this year. 60-pixels doesn't sound like much, but the 1st gen artificial retina brought tears to the eyes of its six recipients, who claim they can now count large objects with just 16-pixels. If all goes well, a 200-pixel retina will be ready in three years; the chip used is of a 1.2-micron CMOS process, with both power and video supplied wirelessly." (And this is sponsored by the Department of Energy for what reason?)

erikaaboe notes that the US Department of Energy has announced a competition to develop efficient solid-state lighting technology. The "L Prize" program will allocate as much as $20 million in cash prizes for innovations to replace the common light bulb. Further details are available at the L Prize website. From the press release: "Lighting products meeting the competition requirements would consume just 17% of the energy used by most incandescent lamps in use today. The plan also includes a rigorous evaluation process, including testing of proposed products by independent laboratories (conducted through DOE's CALiPER test program), as well as field evaluations by DOE and utility partners to assess products in real world conditions. Four major California utilities ... have signed a Memorandum of Understanding with DOE, agreeing to work cooperatively to promote high-efficiency solid-state lighting technologies."

Fysiks Wurks found on the U.S. Department of Energy website news of a breakthrough in solar energy efficiency. From the article: "...with DOE funding, a concentrator solar cell produced by Boeing-Spectrolab has recently achieved a world-record conversion efficiency of 40.7 percent, establishing a new milestone in sunlight-to-electricity performance." A page linked from Wikipedia's article on solar energy calculates the land area that would need to be covered by solar collectors at 8% efficiency to meet the world's energy needs (using 2003 figures). At 40% efficiency, it looks like a square 265 miles on a side in the American southwest would do it.

This is building off of work already done in Scotland (and elsewhere). San Francisco, New York and other areas are considering trial installations of the technology. It is interesting to note (table 1 in the report) that the energy density (kW/m^2) that can be achieved is much higher than wind or solar. In addition, harnessing 24% of available wave energy near the US at 50% efficiency is equal to all of the hydropower currently generated in the US (~7% of total electricity production). On a separate note, in the Office of Energy Efficiency and Renewable Energy's $1.2B 2006 budget the Department of Energy is closing out the Hydropower Technologies Program. Maybe that's why this technology is missing from our National Energy Policy?" Until it reaches maturity, though, U.S. readers can pay for other forms of green energy.

Spy der Mann writes "A Physics Today article entitled The Hydrogen Economy explores the possibility of using hydrogen as an energy source. The article explores the current methods, limitations, and the need for more research. For those wanting to point out the Hindenburg incident, the article doesn't talk about gaseous hydrogen only, but also about hydrogen fuel cells. My favorite quote: 'The natural world began forming its own hydrogen economy 3 billion years ago, when it developed photosynthesis to convert CO2, water, and sunlight into hydrogen and oxygen'. Interesting read for eco-fans."

Shakrai writes "In what will probably be the last we hear of this subject CNN is carrying a story that states what we already suspected: the August blackout was preventable. One of the more interesting observations from this article is that this task force will remain active for the next year to push for their changes and improvements to be adopted. Does anyone think any change will come of this? If you lived in the Northeast US or Canada what were your memories of the August Blackout?" The full report is available at reports.energy.gov.

tttonyyy writes "The US Department of Energy sounded a full scale alert after machines were compromised at the Fermi National Accelerator Laboratory, according to this BBC article. It turns out that the hacker was a student using the machines to download and store music and movies."

will writes "The North American Electric Reliability Council has released four documents concerning the August 14th power outage power outage in the North East. The blackout investigation homepage lists all NERC's documents relating to this event. Press coverage is at The Washington Post, CNN, and CBS News. The take home message: FirstEnergy did it. The are, of course, denying it." The report is also available at reports.energy.gov. Reader stinkydog writes "According to Yahoo News part of the blame for the big fizzle of 2003 lies with a failing SCADA system, GE's XA/21 power management system. 'Not only did the software that controls audible and visual alarms stop working at 2:14 p.m. EDT, but about a half hour later, two servers supporting the emergency system failed, too.' According to the product specs, it is a Unix system with X Windows."

Earlier this week, Energy Secretary Spence Abraham laid out the Office of Science's 20-year plan for building and upgrading the U.S.'s "Big Science" facilities. Twenty-eight programs got the nod, in all. The top priorities -- fusion, and a massive supercomputer. Other goals on the wish list include studying dark energy, high-speed atomic-scale imaging with an electron laser, and fulfilling several particle-physics dreams, including a collider to rival CERN's LHC. Here's the press release and the full list (PDF). Your grandchildren may write school papers on the discoveries these tools will make...

WannabePhysicist writes "Energy secretary Spencer Abraham announced at the Princeton Plasma Fusion Laboratory that the U.S. will join ITER , the international plasma fusion reactor effort. They're currently planning a tokamak (doughnut) design, and have some pretty optimistic energy production predictions for 2014. As many of us in science know, estimated times are usually off by a factor of two, and then sometimes and order of magnitude -- but hopefully they'll get it to work. Many people push this as the cleanest form of energy, but fusion reactors will most likely contain deuterium, tritium, and lithium (tritium's not exactly water) The deuterium and tritium fuse, giving off an alpha (4He nucleus), a neutron, and some energy. This energy causes more reactions (the controlled fusion part). The neutrons hit a 6Li blanket (surrounding the chamber) which then produces more tritium for burning."

An anonymous reader writes "You might have laid Ethernet through some pretty aggressive environments, but how about through a 4-inch diameter steel pipe immersed in electrically conductive mud at pressures up to 1000 atmospheres, temperatures up to 150 deg C, and with vibrational accelerations of hundreds of g? The Department of Energy has announced the invention of a system to allow data transmission up to 1 Mbit/s along drillpipe. That might not sound too fast, but the current technology uses some pretty neat electromechanical engineering to get ... 10 bits per second (on a good day). This will revolutionize the oil industry's ability to see where its wells are going and steer them into pockets of oil."

Deglr6328 writes: "The U.S. Department of Energy's Fossil Energy site has a story about using lasers to drill through rock at 10 to 100 times as fast as conventional rock boring technologies. One of the lasers tested was the 2.2 megawatt M.I.R.A.C.L., which was originally designed in 1985 for the star wars program. A cool video clip of its test firing can be found at the GTI page here. It looks like we'll be stuck with fossil fuels like oil and natural gas for some time, so we might as well do it James Bond style!" Sounds more like Real Genius style to me. Who brought the popcorn?
