any latest news on chines fusion reactor?

10/20/2008 1:06 PM

About two years back a thread was posted by roger pink claiming that china has successfully conducted fusion reactor tests sustaining for 3seconds.

Does anybody have further update on it? Have they improved that 3second mark?

Regards

I don't know maybe CNpower knows, or has it become a pulse reactor?

I dont know as well. Its out of my depth.

I was told this news two years ago, we called it as artificial sun. wonderful future.

The builders are all youngers who are less than 40yds.

Cnpower,

You mean we should not take their claim seriously as they are younger.

No, you are wrong. absolutely wrong.

I m pround of them younger, because they are our chinese future and our pride.

They take any thing seriously, good experience has been made and promoted to international atomic energy colleagues to share their successful and datas.

the problem is the running charge of the set is very expensive high up to 3M dollars per month.

Hi Cn,

I know your forex is touching to USD 2000bn(not a tabloid news), $3MN/day is just about 1bn/year, USD 1bn/year investment for a neverending energy? its very cheep.

Thank you CN.

I wish if they would have fixed some Chinese device on it. Like European and American.

In my opinion if we want to concur the space. we need to start thinking on the philosophy of "one World one Nation".

Is that a Bangl tiger in your avatar? is lovely, but sometimes will be ferocious animal. if we would have dealt with them incorrectly or without careful.

so its impossible for the slogan "one world one nation", just like " one world on dream "

its only a utopia. however we endeavor to struggle for the goal in the world. we wish it could be.

So I prefer to say " peaceful world coloful dreams ". this is more realistic.

The rocket is going to launch off today sometimes I was told, we wish its successful in advance.

Yes Cn you identified it rightly.

Yes I know it's an impossible slogan. Just see the case of the Bengal tiger it is crying here for survival and many drug manufacturer in your country are importing its bones by illegal means for their drugs, and Govt is not putting any ban on it.

If we cannot save this beautiful animal together, what else can be expected?

I was astonished at your words, from where you heard such odd sound?

I didnt expect you dont concern about your lunar mission but turn to such topic. but you bark up the wrong tree.

you should condemn a few robbers in your country who killed that animal for higher profits.

Every year, our goverment sternly punish those smugglers. I took part in a conference where shown us the fruits of fighting with smuggle use new type detectors.

we also sell such machines. as well as luggage detectors.

most of people say that if your gverment would like to spend 1/10 money of launching rocket into your people, thousands of hundreds of your people will have more goood live.

Hi Cn,

I am so sorry if you feel hurt by my words, actually I forget that you belong to Nation,where Nation and regime are considered as two equals, Let me tell you that I have full regards to chines nation.

You talked about robbers (poachers) Yes they need to be condemned and for me they are international criminal.

I don't know about exact level of law enforcement in your country but if every news is not a tabloid for you then there is a room for improvements. At the same time I am sure that you will not deny to the fact that tiger bones are used in china for medical purpose.

Here in India there are many laws and some level of enforcement is available but I am sure it need to be improved and I never mind criticizing Indian regime's loose attitude on this matter.

Where I heard those sounds? Its just one of many links

you may either want to argue with or you hvnt been in the press and dont know how the reports act.

I can only tell you that no goverment in the world like smugglers. why? simple. reduce tax.

you may object your goverment finished the luanar mission, becauseyou may think it will expensie much and your people cannt get something good from it.

thats why you turn theme,

Hi Cn.

When we don't like the fact then we start calling it arguments, but just want to ask you two simple questions--

Do you think White Chinese Panda and Indian Tiger are two equally important animal for this globe? And if Yes

Then do you think that Chinese Govt has taken equally strong steps to save both?

My answer is no. What do you say?

As I know they have done very good job to save White panda.

So long it is the question of lunar mission I am happy with it and looking forward for new developments. But to be very open it could have done much before if our past governments would have not followed Soviet Union blindly.

Implicit in your question is an unstated assumption that a fusion reactor will be a continuous process.

I doubt that. To contain the T and P for fusion requires materials with higher tensile strength that is known to science.

Look at where we have achieved fusion reactions. The so called hydrogen bomb uses a shell arrangement. The outer shell is a mechanical casing, the next is a chemical explosion, the next is a fission explosion and that produces the T & P for the inner fusion explosion. Arguably, the pressure is created by the inertia and acceleration of inward rushing mass as it collapses. Inertial confinement does not need materials with high tensile strength, but I do not know of any alternative to a pulsed environment.

Other proven techniques involve pulsed magnetic fields where pressure is proportional to B^2/mu. When the current pulse that produces the magnetic field is carried in the plasma itself, sufficient P and T can be generated without mechanical confinement.

Work is progressing at Lawrence Livermore on the National ignition facility where photon pressure is planned to produce the compression pulse. I suspect that photon pressure arises from magnetic confinement by the coherent B-fields associated with laser photons.

To my limited understanding, I expect successful fusion technology will involve inertial confinement or magnetic confinement or a combination of the two.

I expect that periodic pulsing of terrestrial fusion reactions will be the first source of net energy yield fusion. I do not yet see a means for achieving continuous fusion on the surface of the earth.

WE should put lots of creative thought into a suitable geometry for a plasma current pattern that produces a self collapsing magtnetic field. Ball Lightning, anyone???

Hi,

Thanks for your comments,

I never stated that a fusion reaction can be only a continuous process, but if someone is aiming to solve the world power needs then this process has to continue for a reasonably longer period. That's why I asked about that 3second mark.

Theoretical explanation is all right. But what I was talking about is the update on someone's claims that they make two years back.

Although this claim was doubted at that time by many.

neednt doubt. because there were lots of foreigners who also took part in the experience.

only some stupid reports who wear out their coloful glasses could speak such words. in order that they could make money from readers pocket.

Are you interested in tabloids?

I was under the impression that the magnetic flux containment within the Tokamak would keep the plasma off the walls and allow known materials to withstand the heat.

I was told this design was prompted by so called the father of russia hydrogen bomb.

very good idea.

I have the same impression of the Tokamak concept.

The two big engineering problems, as I appreciate them, are both because of the Exremely high magnetic fields that are are required. Fields in the range of 100 Tesla or higher would be wonderful.

Last time I looked, the maximum fields produced in superconducting magnets are between 10 and 15 T. The largest in permanent magnets are between 1 and 2 T. These simply will not get the job done.

Higher currents can melt, vaporize and ionize atoms from solid conductors and superconductors. When such physical conductors melt, we are left with a plasma current sheath. Plasma currents suffer from instabilities and do not persist for long. An intuitive view of these instabilities can be obtained from the illustrations found at:

<http://www.netlib.org/utk/lsi/pcwLSI/text/node180.html>

There are, of course, reasonably reliable reports of ball lightning that persists for seconds. I have not found complete descriptions of the geometry for that phenomenon, but it may well be of extreme relevance to the pulsed fusion problem

One CHALLENGE is to design a means for creating and sustaining (for periods longer than a few microseconds) imploding magnetic fields that peak at B > 100T.

The IEEE sponsors meetings and papers under the heading MegaGauss. There you will find the continuing detailed engineering analysis and experimental efforts to achieve steady and pulsed magnetic fields capable of supporting pulsed fusion.

Although designed for use in MRI (magnetic resonance imaging), not nuclear fusion, maybe the 100 T magnet at Florida State University will inspire researchers:

Plasma Confinement sounds soo ridiculously hard, I don't blame people for taking a break on funding until they can figure this out, if at least theoretically.
