Two billion kelvins at Z-machine

Janice Granhardt has pointed out a press release that is two days old and arguably much more serious and potentially far-reaching than the news about "sonofusion" we described yesterday.

In fact, if their projects work out right and some good amount of engineering work is added, the news from their lab may become more important than the news from ITER or other big fusion experimental projects.

The Z-machine at Sandia National Laboratory in Albuquerque, New Mexico - see the picture and click it - was able to heat up their plasma to two billions Kelvin degrees (translation for European readers: two milliards Celsius degrees) which is hotter than the stars. The success published as an article in the February 24th issue of Physical Review Letters (volume 96, No. 7) that most of us no longer read may open a way to build small and cheap power plants. On the theoretical side, they may have mimicked the superhot solar flares.




The lab argues that they have spent 14 months by spectroscopic tests and successful computer simulations by John Apruzese et al. The energy emitted in the form of X-rays exceeded the input kinetic energy by a factor of four, they argue.

Read stories at news.google.com although most of the news are probably just reductions of their own press release that you obtain by click the picture above. Or try to read the PRL article linked above.

  1. One does not ignore the process of what the "new geometries" might imply.

    Just as we are taken to what the new Physics might have been looked at? Quantum gravity, needed analogies for us to push perspective, and make these geometries inclusive.

    An example would be to have all geometries recogized in this process, but you would have needed a basis in which to compare this.

    What would this consistent model be? :)
