Comment Re:Costs? (Score 4, Funny) 73

Given that feathers are much less dense than water, everything else being equal it would cost more to get the feathers there since they enclosure required to contain them would be larger than the enclosure required to contain water.

Things not being equal, feathers are far more compressible than water so you could perhaps increase their density substantially.

You don't specify what condition you want the feathers in. It might be possible to just glue them to the outside of the craft, in which case there are no associated container requirements whereas the water must still be contained. In this case it's going to cost more to get the water there.

On the other hand, if the water was already in orbit it would be as ice, in which case you might be able to just glue a chunk of that to the outside of the craft.

If we're gluing random chunks of stuff to the outside of spaceships, it's probably going to come down to how much friction each material causes and what loss of material each substance would undergo due to space friction.

Submission + - Incandescent Bulbs Return to the Cutting Edge (nytimes.com)

lee1 writes: "A law in the US that is due to take effect in 2012 mandates such tough efficiency standards for lightbulbs that it has been assumed, until recently, that it would kill off the incandescent bulb. Instead, the law has become a case study of the way government regulation can inspire technical innovation. For example, new incandescent technology from Philips, that seals the traditional filament inside a small capsule (that itself is contained within the familiar bulb). The capsule has a coating that reflects heat back to the filament, where it is partially converted to light. The sophisticated ($5.00) bulbs are about 30% more efficient than the old-fashioned ($0.25) kind, and should last about three times as long. So they are less economical than compact fluorescents, but should emit a more pleasing spectrum, not contain mercury, and, one supposes, present the utility company with a more desirable power factor."

Submission + - SPAM: Physical reality of string theory demonstrated

FiReaNGeL writes: "String theory has come under fire in recent years. Promises have been made that have not been lived up to. Leiden theoretical physicists have now for the first time used string theory to describe a physical phenomenon. Their discovery has been reported in Science Express. 'This is superb. I have never experienced such euphoria.' Jan Zaanen makes no attempt to hide his enthusiasm. Together with Mihailo Cubrovic and Koenraad Schalm, he has successfully managed to shed light on a previously unexplained natural phenomeon using the mathematics of string theory: the quantum-critical state of electrons. This special state occurs in a material just before it becomes super-conductive at high temperature. Zaanen describes the quantum-critical state as a 'quantum soup', whereby the electrons form a collective independent of distances, where the electrons exhibit the same behaviour at small quantum mechanical scale or at macroscopic human scale."

Submission + - Planet-forming Disk Discovered Orbiting Twin Suns (takefreetime.com) 1

slreboy writes: "Astronomers have announced that a sequence of images collected with the Smithsonian's Submillimeter Array (SMA) clearly reveals the presence of a rotating molecular disk orbiting the young binary star system V4046 Sagittarii. The SMA images provide an unusually vivid snapshot of the process of formation of giant planets, comets, and Pluto-like bodies. The results also confirm that such objects may just as easily form around double stars as around single stars like our Sun..."

Comment Re:What if we take away too much wind? (Score 4, Informative) 867

The original article was suggesting that there is so much wind around that wind power is a viable power generation method, not that this should actually be done. There's problems with every method of power generation - they all remove energy from the environment.

Maybe with all the deforestation going on there's now too much wind? Maybe we need some way of slowing it down.

You have a really valuable argument that people should spend a lot of time worrying about. It's a real shame that most people won't see it, since it's posted anonymously. Wind is essentially created by heat from the sun. Using all these wind turbines will obviously make the sun go out.

That would be a real problem.

AvantGo created an incredibly powerful, platform independant web browser that was years ahead of it's time. It had features that still aren't in many of the browsers available for hand helds (HTML 4.0 compliance for one). The only downfall was that it converted the DOM into a proprietary storage format and never implemented the ability for the device to read raw HTML. AvantGo management steadfastly refused to allow on device conversion of HTML because they wanted to sell licenses for their server to do the conversion from HTML to the proprietary format.

Sybase apparently bought them for their huge customer base, and never cared about the technology at all - allowing the massive lead to disappear.

Now it's just stomping on the bits.

Plastic and Fuel That Grow On Trees 188

Tim Hanlon writes "Biofuels continue to lead the field in the search for a renewable, environmentally friendly replacement for crude oil. Besides its use in the transport industry, crude oil is also used to produce conventional plastics and chemical products such as fertilizers and solvents. Now chemists have learned how to convert plant biomass directly into a chemical building block that can be used to produce not only fuel, but also plastics, polyester, and industrial chemicals, cheaply and efficiently."

Submission + - Investigators replicate Nokia 1100 banking hack (thestandard.com)

Ian Lamont writes: "Investigators have duplicated an online banking hack using a 2003-era Nokia mobile phone. Authorities had been aware for some time that European gangs were interested in buying the phone, and were finally able to confirm why: It can be used to access victims' bank accounts using "special software written by hackers." The hack apparently works by letting criminals reprogram the phones to use someone else's phone number and receive their SMS messages, including mTANs (mobile transaction authentication numbers) from European banks. However, the only phones that work are 1100 handsets (pictures) made in a certain factory. Nokia had claimed last month it had no idea why criminals were paying thousands of euros to buy the old handsets."

US Federal Government Launches Data.gov 109

Elastic Vapor writes "I'm happy to announce that the US Federal Government earlier today launched the new Data.Gov website. The primary goal of Data.Gov is to improve access to Federal data and expand creative use of those data beyond the walls of government by encouraging innovative ideas (e.g., web applications). Data.gov strives to make government more transparent and is committed to creating an unprecedented level of openness in Government. The openness derived from Data.gov will strengthen the Nation's democracy and promote efficiency and effectiveness in Government." I hope the data reported will be impartially selected, honestly gathered, clearly explained, and perfectly accurate. Perhaps they could start with inspiration from the Concord Coalition's National Debt Counter.

The first plausible use for the plug computer is to attach one of these gizmos to a USB hard drive. Voila, you've got a network server. Cloud Engines, a startup, has in fact built a $99 plug computer called Pogoplug, that will let you share the files on your hard drive, not only in your home but also anywhere on the Internet.

Submission + - Voyager Clue Points to Origin of the Axis of Evil (technologyreview.com)

KentuckyFC writes: "Cosmologists have been scratching their heads over the discovery of a pattern imprinted on the cosmic microwave background, the radiation left over from the Big Bang. This pattern, the so-called Axis of Evil, just shouldn't be there. Now an independent researcher from Canada says the pattern may be caused by the boundary between the Solar System and interstellar space where there is a sharp change in pressure, temperature and density of ions in space. Known as the termination shock, astronomers had thought this boundary was spherical. But last year, data from the Voyager spacecraft which have crossed the boundary, showed it was asymmetric. The new thinking is that the termination shock acts like a giant lens, refracting light that passes through it. Any distortion of the lens ought to show up as a kind of imprinted pattern on an otherwise random image. But the real eye-opener is that as the shape of the termination shock changes (as the Solar Wind varies, for example), so too should the pattern in the microwave background. And there is tentative evidence that this is happening too (abstract)."
