Re:I'd not trust the authors too much.
You could take the plasma out the tokamak and run it through one of these, but what would be the point of generating a hot plasma just to run it through a machine which returns some of the energy you put in?
Well, you'd do that in pulsed power generators, or with waste plasma, which, as I said, may not be applicable to tokamaks - but if I understand it correctly, it would be applicable to this device, if it were actually capable of net power output, which I doubt. I'm surprised you haven't heard about MHD generators. I thought they were quite commonplace in certain applications. The Soviets were using them for geophysical research in distant areas, when they needed high currents and MW levels of power output for short periods. Between being compact enough to fit onto a truck, having something like ~1kWe/kg, and having the ability to start and stop within hundreds of milliseconds, the devices were apparently more suitable for that application than anything else I'm aware of.

Probably Wrong but Clearly Falsifiable
Even though this is probably wrong, just based on the sheer number of prior failures
...Okay, so I'm going to agree with you that it's probably wrong. After reading the paper once last night in a sort of sleepy state, it's certainly a novel way of massaging each 3-Sat problem into an expanded space of memory (compact triplets structures) and then reducing this to solve the problem (all within polynomial time).
So the great thing about this paper is that it's short, it's not theoretical (which is a double-edged sword)/has been implemented (in Java, no less) and it's incredibly falsifiable. I'm not intelligent enough to poke holes in his proofs for this work but people can apply the code to DIMACS formatted problems to their heart's content and if they find one that produces the wrong answer then this is falsified.
I hope we find someone capable of commenting on the proof involving the transformation of the problem from compact triplets formula to compact triplets structure and the hyperstructures presented in the paper. If this is legit, the 3-Sat problem is one that more complex problems are reduced to in order to show that said complex problems are NP-complete. And that's something that's been proved by the Cook-Levin theorem and given in the classic Computers and Intractability: A Guide to the Theory of NP-Completeness by Garey and Johnson.
Refreshingly tangible implementation, if I may say so myself! -
Re:See also: China, Russia....Look at the bottom of that page:
Source: Science and Life, Tatiana Zimin
It is nowhere to be found under the "Press Service Announcements" menu. It's found under "News Archive", on page 384. The "News Archive" seems to be a list of articles in the news mentioning NAS, not announcements from NAS itself.
What articles on the site are critical of AGW? The ones automatically gathered from news sources rather than announcements from NAS itself?

Re:See also: China, Russia....
I tried to find sources in English. If you want a definite Russian one, then here is an article, while not originating from Russian Academy of Sciences, is published on its official website. The first sentence of the article, translated, reads:
"Conclusions about the main cause of global warming made by IPCC do not match the official position of the Russian Academy of Sciences on this issue."
and later on in the text:
"... scientists of the Russian Academy of Sciences, who believe that the present warming has natural character".
As for positions of individual scientists, they differ a lot. If you run search on that website (in Russian, naturally), you'll see that about half of the articles and works speak of AGW (and then usually of consequences, and how to mitigate them), and the other half is critical of AGW. The latter aren't fringe, but high-ranked scienties recognized by Academy awards etc.

Re:China prefers PinkThe Boston Globe
Wikipedia: Red Square, Origin and Name, which says it means both "red" and "beautiful" although the latter is an archaic meaning of the word.
says specifically that "krasny" has lost the meaning "beautiful" over time and the meanign has been applied to red only
Diary of a Russian Wife: Colors in Russian
Moscow Life states the word means "beautiful" in Old Russian and only took on the exclusive meaning "red" in modern times.
The synopsis for the book "Red in Russian Art" tells us that in earlier Russian, the two words carry the same meaning, and that red is still understood to symbolize beauty.
NY Times travel section
This page states that recently as the fifteenth century "red" and "beautiful" were always both exactly the same word. It has its own list of references, too.
This Russian site states specifically:Red Square is located just outside the Kremlin, along it's Eastern wall. In the late 15th Century, people came to this square, called Torg or Market Square, to purchase food, livestock, or other wares. By the late 16th Century, it was renamed Trinity Square, and served as the main entrance to the Kremlin. It got the name Krasnaya Ploschad (Red Square) in 17th Century. In this sense Krasnaya (Red) means beautiful. The Pokrovsky (St. Basil's the Blessed) Cathedral, the Lenin's Mausoleum and the State History Museum are located on Red Square.
Hotel-Rates.com page for Maxima Irbis hotel in Moscow
This sites for a bell foundry in Russia states "Krasny" means "red", and "red" means "beautiful".
Photo tour of Moscow, in which the phrase "Red Square (meaning beautiful square in Russian)" is written.
Another tourist of Moscow reports, "Our first stop is St Basil's Cathedral at the end of Red Square. In Russian, it is Krasne square meaning red or beautiful."
Russian traditional costume seller says, "The word "krasnoye" meaning "red" became identified in the people's minds with "prekrasno-ye" meaning "beautiful". Moscow's most beautiful central square is called "Krasnaya Ploshchad" (Red Square)."
You may notice that Red Square isn't really red...it is paved with black and grey stones. In the Russian language, "Krasny"("red") also meant "beautiful", so "Krasnaya Ploschad" can also be translated as "Beautiful Square". The translation "Red Square" which is now used, was established in the 20th century.
talks about the modern link that still exists between "red" and "beauty"
Eduard Shevardnadze relays to the US State Department Chief of Protocol that krasny can mean "beautiful" as well as "red" -- in 1987.

This problem has been already studied in detail
A prominent russian mathematician A.T. Fomenko from Moscow State University has already proposed and applied the method in question. His goal was to reveal hidden relations in the global history. The "citation index" of certain words would signal some important event like a battle or a outstanding personality. By connecting this words and the dates assigned to them in the ancient texts one could find new relations or use it as experimental evidence for historical theories.
There are couple books of him even in English that are a great fun to read even for non-scientists. Check an abriged version of one of them.
Here is the title of his fundamental work published:
Empirico-Statistical Methods of the Analysis of the Narrative Numerical Material & the Applications of the Problem of Dating
ISBN: 0792326059 - Hardcover - List Price: $266.50
Publisher: Kluwer Academic Publishers - Published Date: 01/01/1994

I doubt it, at least that Rus.Ac.Sc involved
As a former employee of the Russian Academy Sciences (RAS) I strongly doubt that now it is capable of carrying out of anything like this attack. After the collapse of the Soviet Union RAS is in extremely poor condition with most capable people gone either abroad or to commercial companies. Younger people do not join RAS because of very poor working conditions and low wages. It is hard to find anybody younger that 30 there. The monthly salary at RAS is something about US$100 that even in Russia is almost nothing for a computer professional. In fact, I am just waiting when Russian government will openly admit that it does not see any need for science and technology and will close RAS bringing suffering of its employees to the end. And another issue is that very few people in the West understand what RAS is (or was), and RAS name taken alone always leads to some overexpectations. The only thing that RAS has now is its past.
Of course, there is a chance that may be some script kiddy has gotten stuck in RAS but it is quite slim, IMHO. Also in many cases RAS poses simply as an ISP (e.g. domain relarn.ru) that is used by some private and government organization. Some descendants of the Soviet KGB are certainly experienced and capable of cyber attacks.
