Ummmm they didn't try to create a fusion reaction...... Or get any energy out of the system at all...... In fact it is at about half the temperature it needs to be for fusion to work. The whole point of the research currently is to create a system for containing plasma heated to 100,000,000K. The plasma can't come into contact with the walls of the chamber because, either it is so low in mass the chamber instantly cools it, or is has enough mass to melt the chamber walls down.

Once they have a containment system that can run for extended periods of time, the current target is 1000 seconds, then they will look to trigger a fusion reaction inside the super heated plasma. At that point the plasma starts pumping out heat rather than needing it.

I kept reading that and I think something has gone wrong. 15 million K is much higher than absolute zero.... But if I am right about what you are getting at the temps achieved by the German and Chinese tests are higher than the core temperature of the sun. It is because they have to be. One thing that is missing from a fusion reactor that the Sun has is gravity. The sun gets to use a combination of extreme temp & extreme pressure, where as on earth all we get to use is the extreme temperature part.

Their currency is manipulated - as is the US currency it's called Quantative Easing.
They sell pet food that poisons pets. They sell baby formula that harms babies. - Private companies that have been prosecuted, there are heaps of US equivalents. Asbestos is one of the biggest.
  They have no respect for IP property. Why should they? They don't produce large amounts of IP so it makes sense for them to ignore IP law.
They're poisoning their environment such that you can't see across the street due to air pollution, and can't drink the water because of some mining company upstream. - No question it is bad currently, but again every developed economy went through the period of trashing their environment. Not saying it's right but it's pretty much pot meet kettle.
The news media is censored so that non of their citizens know any of this, except what they can see with their own 2 eyes. You haven't been there have you? Yes their media is censored but everyone knows your list.

It is the second Tokamak reactor that China has built and it has been around for about 10 years. There is no inherent reason to disbelieve them. They have come a long way from 20 years ago.

From what I have read China are claiming a significantly lower temperature than the recent German test, approx 30 million degrees K lower, but a much longer duration. The Germans also believe that their system will comfortably run for much longer, the recent operation was just a test so potentially we are seeing a point where engineering capabilities can produce the accuracy of design needed for tokamaks to work.

Comment Re:APorsche Self-Drive? (Score 1) 212

You are kidding right? If you buy a porsche you have decided to buy a drivers car over countless other more comfortable, more relaxed just as prestiges cars. If it is a case of wanting the brag factor and self drive you would buy a tourer shaped car like an Aston Martin Volante or an S series Mercedes.

If you stick self drive in a porsche you have pretty much lost 99% of its bragging rights.

Morning Guys,

ITWBennet is the sort of poster that I, and I believe a lot of crusty slashdot users, are not a fan of. He has no post history and doesn't participate on the site and appears to solely push articles from CSO Online. I know that you need to be putting content on to slashdot but I would rather things others on the site picked as interesting than to read press releases.

Comment Bring in experts (Score 1) 1829

I would love to see the return of the experts in the comments section. Once upon a time slashdot attracted them directly. Now not so much. To try and restore that I would love to see slashdot reach out to people in certain fields to comment on articles. They don't need to be famous people, for example an articulate Maths PhD would contribute so much to those discussions.

But I think slashdot would have to approach them as I really don't want another MDSolar nuclear bad sun good or StartsWithABang I'm talking crap article.

I guess you and I are going to have to agree to disagree on this one. I can see your logic, and I'm not arguing that software should follow the standards. I just don't agree with a computer shutting down without user action. It makes a couple of big assumptions about data being saved and also that the machine will boot back into windows without user interaction (mine doesn't).
