Physicists Build Bigger 'Bottles' of Antimatter to Unlock Nature's Secrets

If this turns out to be workable technology, I'd call it a game-changing thing on a major scale. The fact that they promise commericial production within a few months sure shows chutzpa if it's a hoax!

Right now, converters are made out of silicon and can be 85 percent to 90 percent efficient, i.e., 85 percent of the AC power that gets injected into them comes out as DC power. The rest gets converted into waste heat.
Transphorm can boost that figure to the upper-90-percent range.

Read the comments.
The one comment I took notice of was the comment about the heat loss during switching time.Another was concerned with the truth of the statement that silicon has topped out in efficiency to around 90%. The commenter disagreed, and I tend to disagree also. What is missing here is no talk shows up about efficiency vs operating range. Converters are at their best when running near max output, and so many users of power supplies think bigger is better (in output power) without considering that fact. A 600W supply running at 500W will be, all other things equal, more efficient than a 1000W supply running at 500W.
OK, this is slightly off topic and potentially controversial but I've been getting increasingly hacked off at the shrill media reporting about Japan's nuclear situation. It is definitely Not a Good Thing, but even if it develops into a worst case scenario the amount of people who might die eventually is absolutely miniscule, especially when compared to the tsunami itself. Most news reports have glaring errors that are obvious to a layman...
Well, Chernobyl was even smaller; only one reactor, yet it influence was felt over a large area in Europe.There are 5 in Japan with serious problems, including the spent rod storage problems.
I don't watch the major news any more. If you want to get a better handle on it sites like firedoglake and such are good alternatives. Be advised that the subject is quite technical and difficult even for engineers who are not involved in nuclear power. The implications go way beyond whether those reactors make it or not.
The implication is this:
The default condition of all loss of power is not viable. You cannot lose all power safely with the kinds of reactors which are involved here. No fail safe at all. It's fail at your peril.
If fusion could be harnessed, we would be a lot closer to a fail safe power source of the dimensions perceived for first world needs.
good article!
i like this:
The technology could also be used to transmit data at greater rates than conventional light or radio transmissions. But developing transmitters and receivers for both applications will be difficult, Sergienko says. "The science is known but in practice it's very difficult to do," he says.
translation: the **iaa are afraid of teenagers copying lady gaga songs, so they'll bottleneck this so it never sees the light of day.
If you want to see what the problem entails see if you can find a discussion of the Elitzur-Vaidman bomb testing problem. Don't actually have to test bimbos, but it makes for a bit of edge of your seat reading! It deals with quantum entanglement.
If not on line, find a copy of Penrose: "Shadows of the Mind" starting on p239 ; Sect.5.2
There is also a section titled "Puzzling Election" sect 8.5. de ja vu all over again, and this book was published 1994!
Actually, no. But that is the outcome. Answers from the "Science Genie" is almost always conditional. The answers are not complete and unassailable. They are more like "Yes but..." and when you investigate the but, well hopefully, you don't become the butt of a joke!
(See Cold Fusion)
Most answers come with additional paths that would not have been visible had the question not been formally investigated. Witness FermiLab and the LHC. FermiLab was not likely to answer all the "paths" and a larger more powerful machine is needed. Later, then a larger and more powerful...will be needed.
Eventually the size of the machine needed will be as large as the universe with an equivalent energy in the order of magnitude which existed at the moment of the "Big Bang"( if that is actually what happened!). Did that actually happen? Well, we need a machine larger than the universe and more powerful...YIKES!
An excellent example of the previous post:

And here's the information about the finding presented earlier by FermiLab posted on April 07 2011

Sounds great, but you just KNOW they're going to end up with images that look like this:

The weather this year and it's causes...Global weirding!

Sounds like it's because of the weather! Cycles of warming and cooling have been going on for a very long time now - far before man, as we know him, walked the Earth.
In the 1970's many predicted a "New Ice Age," but then we had a warming cyble, so the blame was put on "Global Warming," and attributed to man, just as that impending "Ice Age" was, decades before.
When it was discovered that for much of the Earth, trends were showing slightly declining temps, the PR firms had to go to work. "Climate Change" was decided upon, as that could explain anything. To paraphrase a research meteorologist, who had predicted the tornados in both CA and across the Midwest and South, with uncanny accuracy, "if cottage cheese were rain from the sky, it would be attributed to Climate Change."
To me, it's just weather.

Going back about 20 years, there were some similar "effects" done with time-lapse. I wish that I could cite the publication, but think that it might have been Popular Photography, with many participants with strobes, road flares, and similar, and one of their "exercises" was a sailboat in a river, illuminated along the path. That was all with stills, and not video, but there were strong similarities.
Thanks for that link,

PS - Speaking of "links," O Winston Link did some interesting shots, with multiple flash (before what we know as "strobes"), on some of his railroad images. Some could be seen as "time lapse," but then some would be called "painting with light."
