That is insane i wonder what will come of this. It could mean engines that work at more than 100% efficiency!

This is fascinating but like everyone else it's hard to get your head around the fundamental importance of what they've discovered after one reading of an article in yahoo.news.

I'll need to go through it again,take my time and try to absorb it properly because after the initial read it seems like a genuine breakthrough that could change our understanding and lead to technology that probably hasn't been thought possible in practical terms up to now.

Like I said,I want to reread it again because I'm not sure exactly if I've read and understood it properly but it does seem to suggest certain laws of physics are breakable that was thought couldnt be broken,notably entropy !!!

Does that mean the laws of thermodynamics are maybe more fluid than was believed ??

Have I read something in it that it isn't actually saying,have I just got the wrong end of the stick.

i'm not too sure but it sounds like it'll fascinating to find out.

Could this allow advances with super conductors too ??

If energy flows from a particle with negative temperature to pretty much anything, that ought to be a positive feedback loop.

The more energy that flows from it, the more negative its temperature ought to go, absorbing energy from everything around it, eventually dropping other particles nearby below 0K, which will also start doing this.

A sort of thermal black hole. Unless the article writer just got the details wrong, which I could believe.
