Dutch scientists develop kite power system with enough juice for 10 homes
Sure, the Netherlands might be known for its windmills, but a group of scientists at the Delft University of Technology is aiming to harness the wind in a different way: by using kites to generate electricity. A recent test generated 10 kilowatts, or enough juice to power 10 homes, and the plan is to eventually send an array of kites called the Laddermill up to 30,000 feet in order to generate nearly 10 megawatts of power. Of course, that’s all in the future — for now, we’ve just got two dudes, a kite, and a pretty dry video after the break.

Not that anyone could really dance around the facts of the matter at this point, but in an email to Apple employees sent today, apparently Steve said, “It was a mistake to launch MobileMe at the same time as iPhone 3G, iPhone 2.0 software and the App Store. We all had more than enough to do, and MobileMe could have been delayed without consequence.” Apple exec Eddie Cue appears to taking the much maligned service under his wing (as well as the App Store, adding to his original gig as VP of iTunes), hopefully making good on the other bit in El Jobso’s email where he resets Apple’s call to action on .Mac’s replacement: “The MobileMe launch clearly demonstrates that we have more to learn about Internet services. And learn we will. The vision of MobileMe is both exciting and ambitious, and we will press on to make it a service we are all proud of by the end of this year.” We’ll see about that!
We don’t take much stock in Digitimes rumors, but the negative chatter about NVIDIA just keeps getting louder — in addition to that nasty defective GPU situation, word is that problems with the nForce line might lead the company to exit the chipset business entirely. According the Inquirer, mobos based on the high-end 790i line have already been pulled by several manufacturers, including Foxconn and Gigabyte, and apparently NVIDIA is asking motherboard makers if it should stay in the chipset game at all and getting lukewarm reactions. Of course, NVIDIA was talking about taking Intel head-on just a few short months ago, so it would be backing down pretty hard if it went back to just making GPUs — not to mention that SLI would essentially die without mobo support and platform initiatives like Tegra would lose tons of momentum. We seriously doubt that the situation is that dire, but right now NVIDIA needs to come out and take control of this mess — where are all the trash-talking execs now?
It looks like a team of UC Berkeley researchers led by mechanical engineering professor Xiang Zhang (pictured) have found a way to squeeze light into tighter spaces than ever though possible, which they say could lead to breakthroughs in the fields of optical communications, miniature lasers, and optical computers. The key to this new technique, it seems, is the use of a “hybrid” optical fiber consisting of a very thin semiconductor wire placed close to a smooth sheet of silver, which effectively acts as a capacitor that traps the light waves in the gap between the wire and the metal sheet and lets it slip though spaces as tiny as 10 nanometers (or more than 100 times thinner than current optical fibers). That’s apparently as opposed to previous attempts that relied on surface plasmonics, in which light binds to electrons and allows it to travel along the surface of metal, which only proved effective over short distances. While all of this is still in the theoretical stage, the researchers seem to think they’re on to something big, with research associate Rupert Olten saying that this new development “means we can potentially do some things we have never done before.
