Chinese-Made Turbines To Fill U.S. Wind Farm


From The Wall Street Journal:

A Chinese wind-turbine company, with financing help from Beijing, has struck a deal to be the exclusive supplier to one of the largest wind-farm developments in the U.S., a sign of how Chinese firms are aggressively capitalizing on America's clean-energy push.

The 36,000-acre development in West Texas would receive $1.5 billion in financing through Export-Import Bank of China. Shenyang Power Group, a five-month-old alliance, would supply the project with 240 of its 2.5-megawatt wind turbines, among the biggest made in the world.

20 Things You Didn't Know About... Sugar


From Discover Magazine:

We eat it, we love it, and it may have been a chemical precursor to life on Earth.

1 The average American eats 61 pounds of refined sugar each year, including 25 pounds of candy. Halloween accounts for at least two pounds of that.

2 Trick: Sugar may give you wrinkles via a process called glycation, in which excess blood sugar binds to collagen in the skin, making it less elastic.

3 Or treat: Cutting back on sugar may help your skin retain its flexibility. So actually, no treats.

Is The Nuclear Material At Los Alamos Safe From An Earthquake?

From Scientific American:

Los Alamos National Laboratory conducts much of the nation's nuclear security research, and a new study has found that the plutonium facility may not be equipped to safely ride out an earthquake.

The lab, situated about 56 kilometers outside of Santa Fe, N.M., has long been known to be on a fault line, and builders have installed substantial fire safety measures. But recent planning for a new structure revealed that the fault could move much more than previously assumed, revealing a crack in the lab's safety plans, the Los Angeles Times reported.

ICANN Approves Non-Latin Domain Names

From CNET News:

The organization responsible for managing the assignment of domain names and IP addresses has approved a new plan to allow non-Latin characters in Web extensions.

Known as Internationalized Domain Names (IDNs), the system is designed to globalize the Net so regions around the world can use their own local alphabet characters to surf in cyberspace, the Internet Corporation for Assigned Names and Numbers, or ICANN, said Friday.

Calling IDNs the "biggest technical change" to the Internet since its birth 40 years ago, ICANN unanimously approved the plan on the final day of its six-day conference in Seoul.

How To Stop A Teapot Dribbling

Photo: No drips: At last, a way to take the mess out of making a cuppa

From The Telegraph:

Britain's tea lovers are raising a cup to scientists after they worked out how to stop a teapot dribbling.

A team of fluid dynamics experts have after exhaustive research concluded that the problem is a phenomenon known as the "hydro-capillary effect".

And the answer is to deploy a "superhydrophobic" material. In other words you could put butter down the spout.

They have deduced that at low pouring speeds tea starts to stick to the inside of the spout, causing the flow to momentarily stop and then start again – in other words to dribble.

From Live Science:

A husband and wife team of paleontologists has discovered a newfound species of armored dinosaur that lived 112 million years ago in what is now Montana.

The duo, Bill and Kris Parsons of the Buffalo Museum of Science in New York, spotted the dinosaur's skull on the surface of a hillside in Montana in 1997. Over the next few years, they retrieved more of the now nearly complete skull along with skin plates, rib fragments, a vertebra and a possible limb bone from the dinosaur species.

Testing Cheap Wind Power

The turbine’s developer, Cedar Park, TX-based Viryd Technologies, claims that its use of mechanical instead of digital power regulation will cut manufacturing costs by 20 percent and boost power output.

From Technology Review:

A continuously variable transmission could lead to cheaper wind power--if it is rugged enough.

Federal stimulus funds awarded to a wind-energy research consortium led by Illinois Institute of Technology will accelerate testing of small wind turbines that could point the way towards more efficient utility-scale machines. The eight-kilowatt turbines, the product of Cedar Park, TX-based Viryd Technologies, use a mechanical approach--continuously variable transmission (CVT) technology--to convert fluctuating wind speeds into the precise stream of alternating current required by power grids. If it can replace the pricey power electronics that regulate power in most turbines today, the same technology could cut the cost of wind-power generation at any scale.

Hubble Captures Sparkling ‘Jewel Box’ Star Cluster


From Wired Science:

This stunning image of the Kappis Crucis Cluster, nicknamed the “Jewel Box,” was one of the last gifts from a retiring camera on the Hubble Space Telescope.

Just before NASA brought the Wide Field Planetary Camera 2 back to Earth in mid-2009, it snapped this photo of the core of the NGC 4755 star cluster, the first comprehensive image of an open galactic cluster taken in multiple wavelengths. Using seven different filters, Hubble captured the Jewel Box cluster in far ultraviolet to near-infrared light. The different colors of the stars — from pale blue to bright ruby red — result from their differing intensities at various ultraviolet wavelengths.

5 Frightening (But True) Space Stories

The First Seven Astronauts

From Discover Magazine:

There's nothing like a good horror story in space*. I grew up watching Sigourney Weaver outsmart xenomorphs in her underwear and subsequently spent a little too much time reading the likes of Stephen King's "I am the Doorway," H.P. Lovecraft's "In the Walls of Eryx" and John Steakley's "Armor."

As a result, it's hard for me to read about space exploration without thinking of about its darker possibilities -- and I don't just mean aliens and distant Hell worlds. Leaving Earth's atmosphere is a dangerous endeavor and, major tragedies aside, there have been a number of smaller terrifying, grotesque and absurd episodes to come out of it. So if you'll allow me to serve as your cosmic Crypt Keeper for a few minutes, I thought I'd run though a few of the ones that get under my skin.
