The Professor: GM's new old engine tech, moon mirrors, the dangers of space war debris
Filed under: Misc. Gadgets
The Professor rounds up a handful of interesting and informative gadget-related science stories from the week and presents them in an easily digestible liquid form.
Having trouble keeping your fingers, thumbs, or eyeballs on the pulse of modern science? Do you find yourself in the throes of panic due to misunderstandings in molecular goings-on? Did the latest aircar, split atom, or robotic insectoid go buzzing over your head before you had time to ready a response? Don't worry friends, The Professor is here to help. Though not an actual scientist, professor, or even a college graduate, he can help guide you through the cascading, complicated, and spasmodic visionary vistas of human invention and achievement as smoothly as a hot knife descending into softened butter.

GreenPix creates massive, self-sustaining LED display in China
Filed under: Displays
A company called GreenPix has created an astounding combination of sustainable technology and digital media virtuosity, dubbed the Zero Energy Media Wall. The system features the world's largest (so they claim) color LED display, powered completely by photovoltaic cells which are integrated into the glass curtain. During the day, the wall -- located on the Xicui entertainment complex in Beijing -- harvests solar energy, then expends the charge at night in a display of undulating colors. The system goes on display this month, but if you can't make it to China, you can watch a video of the work in action after the break.

Is FlipStart closing up shop?
Filed under: Handhelds, Laptops
Look, we're not saying that
FlipStart is
on the way out, but when your "store" page tells people that the stock of your device has been "sold out" and then directs them to a third-party retailer for accessories, things might not be looking so good.
[Thanks, Marke]

Modeling Supernovae With a Supercomputer
A team of scientists at the University of Chicago will be using 22 million processor-hours to simulate the physics of exploding stars. The team will make use of the Blue Gene/P supercomputer at Argonne National Laboratory to analyze four different scenarios for type Ia supernovae. Included in the link is a video simulation of a thermonuclear flame busting its way out of a white dwarf. The processing time was made possible by the Department of Energy's INCITE program. "Burning in a white dwarf can occur as a deflagration or as a detonation. 'Imagine a pool of gasoline and throw a match on it. That kind of burning across the pool of gasoline is a deflagration,' Jordan said. 'A detonation is simply if you were to light a stick of dynamite and allow it to explode.' In the Flash Center scenario, deflagration starts off-center of the star's core. The burning creates a hot bubble of less dense ash that pops out the side due to buoyancy, like a piece of Styrofoam submerged in water."

Bringing Surgical Robots Into the Mainsteam
The New York Times is running a story about how using robots to perform surgical operations has been transformed from a controversial dream to reality. Dr. Frederic Moll abandoned his residency for Silicon Valley and helped to revolutionize the industry. The lengthy article also discusses some of his innovations. We've discussed various robot-assisted medical procedures in the past. From the Times: "'I was struck by the size of the incision and injury created just to get inside the body,' Dr. Moll says. 'It felt antiquated.' He took the idea to his employer, Guidant, a medical device company. Guidant decided that robotic surgery was too futuristic and too risky, so Dr. Moll rounded up backers, resigned, and in 1995, founded Intuitive Surgical. The company prospered by proving that robots could deftly handle rigid surgical tools like scalpels and sewing needles through small incisions in a patient's skin."

Use BitTorrent To Verify, Clean Up Files
jweatherley writes "I found a new (for me at least) use for BitTorrent. I had been trying to download beta 4 of the iPhone SDK for the last few days. First I downloaded the 1.5GB file from Apple's site. The download completed, but the disk image would not verify. I tried to install it anyway, but it fell over on the gcc4.2 package. Many things are cheap in India, but bandwidth is not one of them. I can't just download files > 1GB without worrying about reaching my monthly cap, and there are Doctor Who episodes to be watched. Fortunately we have uncapped hours in the night, so I downloaded it again. md5sum confirmed that the disk image differed from the previous one, but it still wouldn't verify, and fell over on gcc4.2 once more. Damn." That's not the end of the story, though — read on for a quick description of how BitTorrent saved the day in jweatherley's case.

The Mac In the Gray Flannel Suit
oDDmON oUT points us to a BusinessWeek story about the increasing use of Apple products in the corporate sector. Many companies are finding that their employees are pushing for the transition more than Apple itself. Quoting: "While thousands of other companies scratch and claw for the tiniest sliver of the corporate computing market, Apple treats this vast market with utter indifference. After a series of failed offensives by the company in the 1980s and 1990s, Chief Executive Steve Jobs decided to focus squarely on consumers and education customers when he returned to Apple in 1997. As a result, the company doesn't have ranks of corporate salespeople or armies of repairmen waiting to respond every time a hard drive fails. He believes it's difficult for any company, including his, to be effective at satisfying both corporate buyers and consumers."

Dan Rutter Suggests Tossing Some Wi-Fi At the Neighbors
A few days ago, Dan Rutter (the Dan in "Dan's Data") published an interesting idea for extending the sort of philanthropic technical pranksterism that spawned throwies by applying the same approach to Wi-Fi. That means, looking what he hopes is not too far down the road, creating Wi-Fi repeaters that are cheap enough to deploy on the sly and frugal enough with power to run on solar power or cheaply replaceable batteries. But as he says, "If you've got a lot of spare money, a ladder and no respect for private property, though, you could already be stealthily deploying Open-Mesh or other such gadgets all over your neighbourhood." In some cities at least, you'd be hard pressed to ever avoid at least one available wireless access point, but that's not the experience for most people, most places -- which bears correction.

Taser International Wins Lawsuit to Change Cause of Death
I Don't Believe in Imaginary Property writes "Taser International recently started a legal campaign against medical examiners who claimed tasers contributed to the cause of death for several people. On Friday, an Ohio judge ruled in favor of the stun gun manufacturer (free registration may be required). While they do have a number of scientific studies on which they establish their claims, it's interesting that the alternate cause of death they champion — excited delirium — appears only in police reports on the deaths of difficult or drug-addled inmates, not in medical textbooks. Of course, that may change soon — Taser is funding and promoting research on the subject. Coroner reports such as the ones in this case contributed to the UN's opinion that taser use is torture."

Google Pulls Open Source CoreAVC Project Over DMCA Complaint
rippe77 writes "Google has taken down the open-source project CoreAVC for Linux due to a DMCA complaint. The CoreAVC codec is a commercial high-definition H.264 DirectShow filter for windows provided by CoreCodec Inc.. The CoreAVC for Linux project provided various patches for Linux applications (mplayer, MythTV, xine) to use these DirectShow decoder filters in Linux. The takedown is quite controversial, as the CoreAVC project did not provide any copyrighted material — only the means to use the DirectShow filters in Linux." (The takedown notice is not yet up at Chilling Effects, but Google's page has a link that will take you there when it is.)
