schliz writes "Researchers behind the world's largest quantum encrypted network said the technology could secure business networks inside six years. The prototype Quantum Key Distribution network was built by the Secure Communication Based On Quantum Cryptography (SECOQC) group last year. It is described in a journal paper published by the Institute of Physics this week, which includes details on how it is based on the trusted-repeater paradigm."
cheezitmike writes "Researchers at Oregon State University are testing a new type of wave-energy converter to generate electricity from ocean waves: 'Even when the ocean seems calm, swells are moving water up and down sufficiently to generate electricity. ... For decades the challenge has been to build a device that can withstand monster waves and gale-force winds, not to mention corrosive saltwater, seaweed, floating debris and curious marine mammals. ... In the most recent prototypes, a thick coil of copper wire is inside the first component, which is anchored to the seafloor. The second component is a magnet attached to a float that moves up and down freely with the waves. As the magnet is heaved by the waves, its magnetic field moves along the stationary coil of copper wire. This motion induces a current in the wire — electricity.'" Meanwhile, researchers at Stanford are working to design "turbine kites" that operate at 30,000 feet, where air currents flow much faster than they do close to the ground. Ken Caldeira, a Standford associate professor, said, "If you tapped into 1% of the power in high-altitude winds, that would be enough to continuously power all civilization."
Half-pint HAL tips news of UK prosecution lawyers who are instructing police to study information on Wikipedia when preparing to give expert testimony in court. "Mike Finn, a weaponry specialist and expert witness in more than 100 cases, told industry magazine Police Review: 'There was one case in a Midlands force where police officers asked me to write a report about a martial art weapon. The material they gave me had been printed out from Wikipedia. The officer in charge told me he was advised by the CPS to use the website to find out about the weapon and he was about to present it in court. I looked at the information and some of it had substance and some of it was completely made up.' Mr. Finn, a former Metropolitan Police and City of London officer and Home Office adviser, added that he has heard of at least three other cases where officers from around the country have been advised by the CPS to look up evidence on Wikipedia."
