Submission + - Hubble accuracy surpassed by earthbound telescope (arizona.edu)

randuev writes: High-speed adaptive optics system helped Large Binocular Telescope (on earth) to beat accuracy of Hubble Telescope (space) observations.

"A special sensor detects atmospheric distortions in real time and controls the mirror to adjust its position to compensate, effectively canceling out the blurring. The mirror can make adjustments every one-thousandth of a second, with accuracy to better than ten nanometers (a nanometer is one millionth the size of a millimeter)."

Now, that's what I call real-time. This nifty trick multiplied Strehl ratio (optical quality) of LBT by about 80 times to unprecedented Rayleigh limit. Hope we'll see more space around us in higher resolution on Google Sky.


Submission + - Terawatt Research defies free energy stereotype (examiner.com)

An anonymous reader writes: This overunity magnet motor company, Terawatt Research, LLC of Irvine, California, is opposite the typical "free energy" image. They are low on fluff, have never been in the mainstream press; and they are and high on evidence, including test results from TÜV and UL. Both data plots clearly show performance frequency ranges in which much more energy is produced from the system than what is required to drive the system – at least three-fold. They say they are "harnessing the energy of intermolecular fluctuations." Back in September of 2006 the inventor said in essence that "The basic premise of the technology is that nature seeks symmetry and balance. The symmetry has inner stability. A temporary imbalance imposed wants to return to balance. This force can be harnessed for output energy." On their home page they say: "We developed a technology that allows this oscillation to be permanently harnessed." As another contradiction to typical free energy companies, one of their strategic advisors — not suppressors — served as former director of the CIA and of the FBI. Another contrast is their plush digs in Irvine, Calafornia; compared to a garage, which is the typical free energy inventor's laboratory.

Submission + - Reverse-engineering the Netherlands dyke system (www.nrc.nl)

vikingpower writes: "Built in reaction upon a major flood that killed 1800 in the '50s of the last century, the Dutch system of dykes, sluices, surge barriers and dams has been dubbed "one of the seven wonders of the modern world" by the American Society of Engineers. Now, there are proposals to use the system differently, e.g. as tidal power plants by punching holes in them. Any civil engineer will probably be mouth-watering when thinking of the mega-projects this could give rise to."

Submission + - The predictioneer: Using games to see the future (predictioneersgame.com)

parallel_prankster writes: Bruce Bueno de Mesquita is a professor of politics at New York University and a senior fellow at the Hoover Institution at Stanford University in California. In his new book, The Predictioneer (The Predictioneer's Game in the US), he describes a computer model based on game theory which — and others — claim can predict the future with remarkable accuracy. The primary website link also has a game page where he provides an online version of the game and information on how to play.
"Over the past 30 years, Bueno de Mesquita has made thousands of predictions about hundreds of issues from geopolitics to personal problems. Overall, he claims, his hit rate is about 90 per cent. So how does he do it? What more, the CIA seems to be using this model to predict the outcome of political situations around the world!!". The original article from NewScientist (semi-walled, may need to register) is here: http://www.newscientist.com/article/mg20527520.500-the-predictioneer-using-games-to-see-the-future.html?page=1


Submission + - Laser And Nanoparticle Engine To Reduce Emissions (motorauthority.com)

thecarchik writes: So, how, exactly, does one take low-energy lasers, nanoparticles and fuel and come up with a lean, green machine? The answer is suprisingly simple, if you don't dig too deep. Tiny particles called "functionalized fullerenes" help fuel to burn at lower ignition energies, meaning a lower-power ignition source can be used. That's where the low-power laser comes in. Not much more powerful than a typical laser pointer, the laser sets off the fullerenes, which then ignite the fuel--but because they're nanoparticles and distributed throughout the fuel, they help to make for more complete combustion, improving the overall thermal efficiency of the engine. The sum total of the equation? Less fuel for the same power output.

Submission + - Izumi says run-of-river turbine cheaper than grid (examiner.com) 1

An anonymous reader writes: A Slovenian turbine-generator called the SP River Pump that is designed to work in relatively slow and shallow moving water supposedly could not only provide clean energy but at a price point many times cheaper than the cheapest grid power presently available. You have to admit that the design is eligantly simple and sound. But could it deliver on the inventor's claim that it could be produced for as much as seven times cheaper than grid power?

Submission + - Noble Gas engine a finalist for prestigious award (examiner.com)

An anonymous reader writes: PlasmERG Inc., who is developing a noble gas plasma expansion motor that could revolutionize the renewable energy industry with clean, cheap, and reliable power has been selected as a top five finalist among the "Most Promising Renewable Energy Technologies" category for EE Times' prestigious Annual Creativity in Electronics (ACE) Awards, with media sponsorship by IEEE Spectrum. Is it really possible to run an engine on inert noble gas?

Submission + - Programmer blamed for St.George Bank data leak (itnews.com.au)

schliz writes: St.George Bank in Australia has mailed the details of up to 42,000 account holders to other customers. The error was blamed on a programmer at business process outsourcing company Salmat, who "manually intervened" when a file was found to be corrupted during the automated process. Disciplinary action is expected to be taken.
