dcblogs writes "The U.S. Dept. of Energy has set a goal to develop battery and energy storage technologies that are five times more powerful and five times cheaper within five years. DOE is creating a new center at Argonne National Laboratory, at a cost of $120 million over five years, that's intended to reproduce development environments that were successfully used by Bell Laboratories and World War II's Manhattan Project. 'When you had to deliver the goods very, very quickly, you needed to put the best scientists next to the best engineers across disciplines to get very focused,' said U.S. Energy Secretary Stephen Chu, on Friday. The Joint Center for Energy Storage Research isn't designed to seek incremental improvements in existing technologies. This technology hub, according to DOE's solicitation (PDF), 'should foster new energy storage designs that begin with a "clean sheet of paper" — overcoming current manufacturing limitations through innovation to reduce complexity and cost.' Other research labs, universities and private companies are participating in the effort."

gbrumfiel writes "The Curiosity rover will soon start rolling, and when it does, it will be running on gas from a Russian weapons plant. Slate has the story of how the plutonium-238 that powers the rover came from Mayak, a Soviet-era bomb factory. Mayak made the fuel through reprocessing, a chemical process used to make nuclear warheads that also polluted the surrounding environment. After the cold war ended, the Russians sold the spare Pu-238 to NASA, which put some of it into Curiosity. Now, the Russian supply is running low and NASA hopes to restart Pu-238 production on U.S. soil (They're planning on making less of a mess this time)." One interesting way of dealing with nuclear waste: reprocess fuel a few times, extracting Pu-238 and friends (those pesky "have to keep waste sealed forever to prevent hyper-squirrels in the year 3,001,000 from being irradiated" elements) and launching an army of deep space probes. But then there's the waste stream from reprocessing...

An anonymous reader writes "A Wall Street Journal columnist recently got his hand on a power meter and decided to write about his findings, the resulting article being discussed here on Slashdot. That author concluded that gadgets are getting a bad rap, and are relatively insignificant power consumers in the grand scheme of things. A rebuttal has appeared, arguing that not only are modern electronics significant power consumers already, while everything else is becoming more efficient, home electronics seem to be getting worse. This echoes the Department of Energy's assertion that 'Electricity consumption for home electronics, particularly for color TVs and computer equipment, is also forecast to grow significantly over the next two decades.' Are gadgets unfairly maligned, or getting an unearned pardon?"

deblau writes "On July 27, scientists at the National Nuclear Security Administration's Nevada Test Site said they generated a current equal to about four times all the electrical current on Earth. During the few millionths of a second that it operated, the 650-ton Atlas pulsed-power generator discharged about 19 million amps of current through an aluminum cylindrical shell about the size of a tuna can. Official news release is available from the DOE (PDF)."

jonerik writes "According to this article from the Associated Press, the US government is this week permitting the public a rare glimpse of its high-security Y-12 nuclear weapons plant as part of Oak Ridge, Tennessee's annual Secret City Festival, which is being held this coming weekend. Although the plant is still associated with ongoing nuclear weapons work, members of the public will be permitted to see parts of the facility associated with its work on the Manhattan Project's 'Little Boy' bomb, which was dropped on the Japanese city of Hiroshima on August 6th, 1945. The facility produced the uranium-235 which was used in the device using 1,152 massive calutrons across nine separate buildings in 1944 and 1945. 'Don't you know the people in Knoxville wondered what in the world was going on out here,' Department of Energy guide Ray Smith said on Monday. 'All this material was coming in, truckload after truckload, and nothing ever left.'"

Lecutis writes "National Nuclear Security Administration (NNSA) Administrator Linton F. Brooks announced that on March 23, 2005, a supercomputer developed through the Advanced Simulation and Computing program for NNSAs Stockpile Stewardship efforts has performed 135.3 trillion floating point operations per second (teraFLOP/s) on the industry standard LINPACK benchmark, making it the fastest supercomputer in the world."

thhamm writes "The DOE Report on Cold Fusion (mentioned here too) is out. Take a look at it on the DOE Website. Well, looks like there is nothing really new since Pons & Fleischmann in 1989, because "While significant progress has been made in the sophistication of calorimeters since the review of this subject in 1989, the conclusions reached by the reviewers today are similar to those found in the 1989 review.""

drjzzz writes "Federal Computer Week reports that the National Nuclear Security Administration of the US Department of Energy is paying about $3 million of a $6.8 million collaboration between Silicon Graphics and the Universities of Maryland and Wisconsin to develop an open-source version of SpeedShop, SGI's performance analysis tools. This will redress what a SGI engineer characterizes as scarce analysis software for Linux. A "Pro" version will also be developed and sold by SGI. Maybe even those of us without access to ASCI White can tweak our boxen to do 3D simulations of complete nuclear detonations, NNSA's main interest. Now that's what I call homeland security and real respect for the spirit of the second amendment."

Ckwop writes "The Daily Telegraph is reporting that Amec, the company that cleaned up Ground Zero, have developed a new process for storing nuclear waste that lasts two hundred thousand years - far longer than any radioactivity will last. The process works by mixing eighty percent soil with twenty percent waste and then heating the mixture to three thousand degrees centigrade. When the mixture cools it forms into a glass harder than concrete. While this is not the first waste process of this type it is the first to be cost effective and produces a glass much harder than previous methods. " We'll see if we still need a ten mile field of spikes I guess. A pilot facility is being built in Washington State.

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...

VernonNemitz asks: "Back in 1984 a patent was granted for silicon chip micro rectennas, which would convert visible photons into electricity in the same way that ordinary rectennas convert microwaves into electricity, at perhaps 70% or greater efficiency. Nobody could make such solar cells back in 1984, but we certainly can today, with sizes of antennas that would capture everything from infrared to the edges of UV -- and the patent has expired. So, where are they?" Currently the most popular type of solar technology is photovoltaics, however PV technology only has an efficiency of about 7-17%. With the potential gains claimed by the technology in the cited patent, has anyone even tried to build one of these units to see if it can live up to the given promise, or at least prove to be a technology than we should be exploring?

HobbySpacer writes: "The BBC reports that waste CO2 from methane extraction in the North Sea has been succesfully pumped back into the pourous sandstone beneath the ocean for the past 6 years without any signs of leaking. Carbon sequestration techniques like this are looking increasingly practical. CO2 is being pumped back into depleted oil fields, where it also helps extract remaining oil deposits, and into coalseams. The ocean is the biggest natural bank of CO2 but tests of ocean sequestration in Hawaii and Norway have been blocked by environmentalists who hate this kind of quick fix approach to the CO2 problem. But with developing countries like India and China certain to rely on their large coal reserves, sequestration may be the only realistic approach to reducing their CO2 output. An Economist article discusses currently available steam reformation technology that could allow a coal plant to output power and neatly separated CO2 and hydrogen. The non-polluting hydrogen is then available for cars with fuel cells while the CO2 is stuffed away."

!splut writes "Fusion fans out there will be interested to know that an experimental French fusion reactor has set a new duration record of 210 seconds. Most fusion reactor research works (or tries to) by containing and compressing a quantity of plasma via an electomagnetic field in a toroidial chamber. Fusion energy could potentially provide a a clean, efficient, and virtually inexhaustible source of energy, but fusion reactoins have proven difficult to contain and control, so this is a significant achievement."

scottennis writes "Yahoo is carrying a story about Iceland's plan to wean itself from fossil fuels. The article states that Iceland is giving itself 30-40 years to kick the oil habit completely. Of course some researchers estimate that in 30-40 years we won't have much of a choice."

In what must be a dream come true for some, Nevada has approved a License Plate commemorating the Test Site and the connections Nevada enjoys with Nuclear weapons in the United States. The Associated Press article on the subject notes that a lot of people are up in arms about the new design, as Nevada is embroiled in controversy over the Yucca Mountain nuclear waste storage facility. The license features an atom. a mushroom cloud as the background and the equation E=mc² on the plate. I was unable to find a picture of the plate on the web (I saw it in my morning paper). I'm sure a picture must be on the web somewhere. I'll leave it to slashdotters to suggest the best personalized lettering for the plate. My entry: DUKNCVR?

jhiv writes: "The National Nuclear Security Administration (NNSA) reports that 'Los Alamos and Lawrence Livermore national laboratories have completed the first full-system three-dimensional simulations of a nuclear weapon's explosion'. The simulations are two of the largest computer simulations ever attempted, each taking weeks to complete on the ASCI White supercomputer. The Los Alamos team used the ASCI Blue Mountain supercomputer to visualize the results. Additional coverage can be found in this story in the Albuquerque Journal."

Steve Hamlin writes "A researcher at Lawrence Berkeley National Laboratory, and his colleague at the Center for Advanced Computation at Reed College, have taken a major step toward answering the age-old question of whether the digits of pi and other math constants are "random." In addition, a simple formula discovered makes it possible to calculate the Nth binary digit of Pi without computing any of the first N-1 digits, and do the computation with very little computing power.

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?

The U.S Department of Energy will launch a project called "Pathforward" this month. The project aims to build a 30 terraflop supercomputer by the year 2001. The U.S DOE will buy 2 IBM PowerPC-based supercomputers with 4096 processors in late '98 or early '99 and will buy a second 3 terraflop based computer from Cray Research Inc. later that year.

Hewlett-Packard is the main contractor in charge of designing externalconnect links so that the computers may be clustered efficiently (more than 6.4GB/sec, minimal latency)

When do I get one? =)
