500,000 RPM matchbox-sized gas turbine produces 100 watts

October 1, 2006 Researchers at the ETH Chair for Power Electronics have developed an electrical generator that spins at a world record 500,000 revolutions per minute (RPM) and scientists are hopeful they can achieve twice this speed to touch the magical million rpm. The matchbox-sized motor generates the equivalent of 100 watts, including the power electronics interface, and has an efficiency of close to 95 percent. Powered by a gas turbine, one tankful of fuel drives the generator for about 10 hours at peak 100 watt performance. These ultra small gas turbines could replace conventional batteries as a mobile power source and have a range of potential applications, from dentistry where ever smaller holes could be drilled with ever higher rotation speed through to energy supply for mobile applications, such as portable heart-lung machines or artificial hearts. The little motors could also be used in turbo compressors, which condense gas mixtures or air.

Play against Xbox360 gamer on PC in Vista

Microsoft Corp. co-founder Bill Gates on Tuesday announced a cross-platform gaming service that integrates games played on cell phones, Xbox 360 consoles and the upcoming Windows Vista operating system. The "Live Anywhere" service will be available as part of Windows Vista, Microsoft's next-generation PC operating system. The consumer version is scheduled for release early next year. "It means that you have one online community," Gates said in a news conference. "This platform can really unleash developers to do amazing new things." The system would extend the company's existing Xbox Live service for the Xbox 360 console into millions of Internet-enabled PCs and cellular phones. No pricing information on the new service was announced. In recent months, Microsoft has been pushing a number of online services that it hopes will boost revenue as markets for its traditional software become increasingly saturated. The company expects to make money off s...

Welcome to Google Checkout, that will be $3.14

From ZDNet The first time I looked up the domain " GDrive.com " it appeared that someone other than Google had it registered. A trip down memory lane takes us to my very first article that describes how I determined GDrive.com is in fact owned by Google, despite what it looks like on the surface. Well, by the same logic I have found that a brand new set of domains appearing to be registered to someone else were actually registered by Google on May 25th. The domains googlecheckout.net / org / info (.com is owned by someone else at the moment) have all been registered to a company called DNStination, Inc. Don't be fooled, the registrar is MarkMonitor — a company that prides itself on the protection of your corporate identity. There is no way they would let just anybody register a domain with "Google" in it — especially since Google is one of their clients. Then who is this DNStination, Inc. then? Googling the address of this "company" tell...

Hackers biting Apple

Hackers are increasingly focusing on Apple's Mac OS X, and the number of newly discovered vulnerabilities has surged. Such a switch could mean big implications for Apple's user base, which has traditionally not had to concern itself too much over security. It's been an impressively quiet year so far on the PC virus and worm front, and hackers seem to be focusing their attention elsewhere. One such area is Apple's Mac OS X. Once mostly ignored by malware developers, there appears to be a growing interest in this "alternative" OS. Details Have you noticed the dearth of serious PC virus and worm threats out there lately? Well, it isn't a figment of your imagination -- according to vnunet.com, viruses are no longer the top security threat . While serious attacks are still likely to emerge, the bottom has apparently fallen out of the PC antivirus market -- just as Microsoft begins a big push into the security market. One cause of this drop-off is solidif...
