Capturing Solar Power With Antennae
necro81 writes "Researchers at the University of Missouri and the Idaho National Laboratory have demonstrated a new method of capturing solar power. Rather than using semiconductors to capture photons of sunlight, they fabricated small coiled antennae (several um square) that resonate with the wave nature of light. The antennae are tuned towards midrange infrared light (5-10 um), which is abundant on our cozy-warm Earth — even at night. They also demonstrated a way to imprint these coils on a substrate, like how CDs or vinyl records are produced, but could be scaled to roll-to-roll mass production. The usual caveat applies: it may be 5-10 years until this could hit the market." -
Slashback: ASIMO History, CSIRO WiFi, Net Neutrality
Slashback tonight brings some corrections, clarifications, and updates to previous Slashdot stories, including a short history of Honda's ASIMO. Also, Intel bows out of the embedded processor market, Microsoft's USB giveaway fizzles, CSIRO gets close to a WiFi win, lawmakers target MySpace again, and the New York Times weighs in on net neutrality. Read on for details.A Short history of Honda's ASIMO. Ant writes to tell us that Honda has posted a short overview of the evolution leading up to the ASIMO. The history showcases the progress Honda has made in robotics over the last 20 years. It contains drawings, photographs, specifications, and other information about each prototype.
Intel bows out of the embedded processor market. markrages writes "Embedded.com is reporting Intel is withdrawing from the embedded processor market. From the article: 'The company will stop producing the 8051, 251, 8096/196, 188/186, i960, all versions of the 386 (including the 386EX) and 486.'" The product change notification is also available from Intel's site.
Microsoft USB giveaway fizzles. An anonymous reader writes "If you thought you could get something for nothing from Microsoft. Think again. NetworkWorld is reporting that Microsoft is backing down from the free USB drive marketing promotion they launched last February."
CSIRO close to WiFi win. Trapped Database Adm writes "Australian IT reports that Leonard Davis of the U.S. District Court for the eastern district of Texas issued a Markman opinion, providing 'strong support for CSIRO's position in its patent infringement test case.'" From the article: "The CSIRO claims its patent relates to several wireless standards, and the technology covered by its patent is a standard feature of most notebook computers and many other devices. Many technology companies are refusing to pay up, however."
Lawmakers target MySpace again. ardyng writes "It appears Congressman Michael G. Fitzpatrick,(R-Penn) has introduced a bill to the U.S. House of Representatives that would ban minors from accessing social networking websites such as Myspace, as well as any site that 'allows users to create web pages or profiles that provide information about themselves and are available to other users; and offers a mechanism for communication with other users, such as a forum, chat room, email, or instant messenger. The Bill, H.R. 5319, also known as the 'Deleting Online Predators Act of 2006', is still in its infancy, but in its current form, would forbid libraries from allowing access to such sites as well." (That description would also include the site you're reading now.)
New York Times weighs in on net neutrality. KarmaOverDogma writes "The New York Times' Adam Cohen provides an argument in favor of neutrality on the World Wide Web. Cohen succinctly provides a brief history of the World Wide Web, its creator Tim Berners-Lee's vision of how it should operate, why he designed that way, and the forces moving to create a tiered pricing system of access. From stifling creativity and competition to free speech and innovation, Cohen shows why strange bedfellows have come to favor enforcing the 'Democratic Ethic' of the internet by Legislation."

Senate Candidate Wants to Ban Polling
Masker writes "This is just too funny. Alan Keyes, the Republican candidate for Senate in Illinois, who is running against Democrat Barack Obama, wants to ban political polling for 'a certain period' before the election, since such polls are 'manipulative and degrading and damaging to our political system.' Could his opinion be influenced by a recent poll that shows Keyes trails by 45 percentage points behind Obama?" Could be. But it could also be influenced by the fact that polls are often wrong; they influence how people vote (people are less likely to vote for someone who "doesn't have a chance"), and polls get reported on more than issues, which can't be good for anyone except the pollsters and whoever happens to be leading the polls. -
Hiring Artists for Open Source Projects?
MikeFM asks: "What is the best way for an Open Source developer to hire artists to provide graphics, music, and other artwork for Open Source projects? I need to hire such people and I'm not sure where to go or how best to spell out the terms of the contract so that it's okay to release the works for hire as Open Source. I'm willing to pay but can't afford to pay a lot. It seems to me that providing artwork for an Open Source project sounds like great exposure to art students and artists still early in their career but how do I find these people? I've posted ads in the local schools and art stores.. what else can I do?" -
Ken Brown Responds to His Critics
An anonymous reader writes "Yes, I know it's getting boring by now, but the truth must be told... the latest Unix celebrity to come forward and criticise Ken Brown/ADTI is Unix pioneer Dennis Ritchie. The gist is that Brown is claiming an 'extensive interview' with Ritchie but this was actually limited to a single email exchange and a follow-up call from one of Brown's lackeys checking one or two facts." Reader markrages writes "Ken Brown (of the Alexis de Tocqueville Institution) replies to his critics. Dr. Tanenbaum is an 'animated, but tense individual about the topic of rights and attribution'. The GNU/Linux naming issue also makes an appearance." -
Anti-Frostidigitation: Heatpipe Gloves
Hettinga writes "A little casemod couture this morning, courtesy of Hongbin Ma, a professor of Mechanical and Aerospace Engineering at the University of Missouri. He has developed heatpipe-driven gloves which pump therms from your toasty upper arm down to those aforementioned frosty digits. 'Each glove contains five small heat pipes, one for each finger, that are about 14 inches long and 1 mm x 2 mm in the cross section. Each pipe consists of three sections: an evaporating section, which is attached to the upper arm area; an adiabatic section, which is between the finger area and the arm area; and the condensing section, which is attached to the finger area.' Coming soon to a half-pipe near you..." -

Rise of the Triad Source Code Released
Woody writes "3DRealms gave us an early Christmas present this year: they've released the complete Rise of the Triad source code in memory of William Scarboro, one of the game programmers who died earlier this year. The source is being released under the GPL, so everyone should be happy. If you ever played ROTT, you might remember that under all of the silliness and gore there was an incredible deathmatch and capture-the-flag element. Discussions are currently starting in the 3DRealms forums. Thanks, 3DRealms!" -
Experiment This Weekend To Measure Speed Of Gravity
An anonymous reader writes: "Is gravity an instantaneous phenomenon, as we were taught in high school, or is its speed, like all other Einsteinian phenomena, bounded by the speed of light? A radical new experiment, proposed by Sergei Kopeikin, and involving the Very Long Baseline Array, is set to occur this weekend, and results should be known within about two weeks." -
Northern Lights Not So Northern
Several readers have written with news of an unusual display of the Aurora Borealis, among them Georgie Porgie, who writes: "Crawl away from those terminals and step out side for a view of the norther lights... I am in Columbia, Missouri, USA Approx 39.9 N latitude and I am looking at the northern lights... Hope the networks are up tommorow... See what causes the lights at http://www.spaceweather.com/" fjordboy points to this excellent noaa.gov link, too.
