Factory-Built Nuclear Power, Coming To A Lab Near You
Posted in: green, research, science, Today's ChiliPrefab nuclear power plants might sound straight out of a 1950’s vision for the nuclear age, but the technology may be on its way to laboratories across the country. The New York Times is reporting that the Obama administration’s budget, which will be officially proposed tomorrow, includes funding for research into low-cost, modular nuclear plants that can be quickly assembled and shipped without the overhead of traditional designs. Designed to be deployed at first in large-scale national laboratories, like the Oak Ridge National Laboratory in Tennessee, the plants cost up to $2 billion, a small fraction of the $10 billion price of a typical nuclear reactor, but offer about 1/20th of the output. The use of these reactors is expected to help the Energy Department lower its carbon footprint by 28 percent before 2020.
In the long-term, this research is expected to yield the ability to mass-produce these power plants, assembly-line style, allowing them to replace existing coal plants already on the grid. According to the Times, this type of modular reactor saves utilities from the large start-up costs associated with building a traditional reactor, allowing for more options when it comes time to replace older, less environmentally-friendly plants. They also produce roughly the same amount of power as older coal plants from the middle of the century that are now nearing retirement.
The administration will likely be asking for $500 million over five years, which will pay for half of the design costs for two reactors.

Move Over Electronics: Atomtronics Offers New Possibilities
Posted in: laser, science, Today's ChiliElectronics? That’s so 20th century. Physicists at the Joint Quantum Institute have made a significant advancement in the field of atomtronics, using atoms in certain quantum states instead of electrons to build devices. According to an article published on ScienceNews.org, the field has already yielded a number of designs for the replacement of standard electronic components with atomtronic ones. Now, the physicists have created a ring-shaped condensate that they say could be used to create an extremely accurate rotation sensor. This isn’t the kind of thing you can expect to see in your next cell phone though; the process requires precise laser beams and a way to chill the condensate down to just a few billionths of a degree above absolute zero.
Despite the experimental nature of the field, this discovery marks an important achievement, as it’s the first time anyone has created a ring-shaped condensate. The tiny circle of gas only lasted for about 40 seconds, but that was long enough for the team to measure its frictionless spin, set to about one revolution per second. This isn’t quite the rotation sensor itself, but one could be built from it, using a barrier that would cause changes in current when rotated at certain speeds.
ScienceNews.org said the pioneers in the field hope that “atoms will prove to be more interesting than electrons.” When was the last time you heard about an electronic sensor that used near absolute zero temperatures and lasers to create a frictionless ring? I’d say atomtronics has already gotten to a pretty interesting level. Hopefully, there’ll be more to come.

Tomorrow marks the 202nd anniversary of Charles Darwin’s birth. The scientist, best known for introducing the concept of natural selection in his 1859 book, On the Origin of Species, led a fairly interesting life outside of his scientific work, as well. After the jump, check out some fascinating facts about the scientist you thought you knew.

Between this anniversary and the fact that next week mark’s the long awaited match between the company’ Watson computer and two of Jeopardy’s winningest champions, it’s a good time to reflect on some of the more important moments in mankind’s battle against technology.
IBM’s Mira supercomputer does ten petaflops with ease, inches us closer to exascale-class computing
Posted in: science, Today's Chili, usSay hello to the Blue Gene/Q, or if you’re looking for something a bit less intimidating, “Mira.” That’s IBM’s latest and greatest concoction, a ten-petaflop supercomputer capable of running programs at ten quadrillion calculations a second. Hard to say who’d win between Mira and Watson, of course, but there’s absolutely no question who’d come out on top if Mira were pitted against her predecessor Intrepid (hint: Mira’s 20x faster). To put this all in perspective, IBM‘s chiming in with this:
“If every man, woman and child in the United States performed one calculation each second, it would take them almost a year to do as many calculations as Mira will do in one second.”
Mira’s next stop is at the US Department of Energy’s Argonne National Laboratory, where it’ll be used to tackle 16 projects in particular that were drawn from a pool of proposals to gain access to her capabilities. We’re told that these include a range of initiatives — from reducing energy inefficiencies in transportation and developing advanced engine designs to spurring advances in energy technologies — and in time, it could lead to exascale-class computers “that will be faster than petascale-class computers by a factor of a thousand.” And here we are getting excited about a 5GHz Core i7.

How Jules Verne Invented NASA
Posted in: science, space, Space Tech, Today's Chili“A hundred years ago, Jules Verne wrote a book about a voyage to the Moon. His spaceship, Columbia, took off from Florida and landed in the Pacific Ocean after completing a trip to the Moon. It seems appropriate to us to share with you some of the reflections of the crew as the modern-day Columbia completes its rendezvous with the planet Earth and the same Pacific Ocean tomorrow.”
Those are the words Apollo 11 commander Neil Armstrong recited for an entranced public as his ship returned from its mission to the moon. Armstrong was right to mention Verne’s 1865 sci-fi classic. There are, in fact, some oddly prescient details in From the Earth to the Moon–even for an author so forward thinking as Verne.
Armstrong points out the similarities between its name and the name of the Apollo 11’s command module–that part’s actually only part right. The name of the space cannon used to launch the ship was the Columbiad, named for a real U.S. cannon that was used heavily in the war of 1812.
Verne estimated that the mission would have cost his day’s equivalent to $12.1 billion. Surprisingly spot on–the Apollo program up through Apollo 8 (the first manned vehicle to circumnavigate the moon) cost $14.4 billion. As with the book, that mission also a crew of three astronauts. Verne’s were named Ardan, Barbicane, and Nicholl–Apollo 8’s were Anders, Borman and Lovell.
The launch occurred 132 miles from the site of Verne’s prediction. As the above shot illustrates, the two ships also shared a number of physical properties.
The divers discovered 145 bottles of champagne and five bottles of beer on the ship. The beer has since been consumed by professional beer tasters. Said Annika Wilhelmson, an observing scientist, “They said that it did taste very old, which is no surprise, with some burnt notes. But it was quite acidic – which could mean there’s been some fermenting going on in the bottle and with time it’s become acid.”
The Technical Research Centre of Finland has since been commissioned to figure out exactly what the beer was made out of. Wilhemson again, “We’re going to try to see if we can find any living yeast or other microbial cells, because that would be very interesting with respect to reproducing the beer.”
One the recipe is discovered, the beer will be brewed again.
