Scientists have produced superheated gas exceeding temperatures of 2 billion degrees Kelvin, or 3.6 billion degrees Fahrenheit.
This is hotter than the interior of our Sun, which is about 15 million degrees Kelvin, and also hotter than any previous temperature ever achieved on Earth, they say.
They don't know how they did it.
One thing that puzzles scientists is that the high temperature was achieved after the plasma’s ions should have been losing energy and cooling. Also, when the high temperature was achieved, the Z machine was releasing more energy than was originally put in, something that usually occurs only in nuclear reactions.
The Z Machine is now able to propel small plates at 34 kilometers a second, faster than the 30 kilometers per second that Earth travels through space in its orbit about the Sun. That’s 50 times faster than a rifle bullet, and three times the velocity needed to escape Earth’s gravitational field.
The ultra-tiny aluminum plates, just 850 microns thick, are accelerated at 1010 g. One g is the force of Earth’s gravity. Doing so without vaporizing the plates was possible because of the finer control now achievable of the magnetic field pulse that drives the flight.
Z’s hurled plates strike a target after traveling only five millimeters, or less than a quarter-inch. The impact generates a shock wave -- in some cases, reaching 15 million times atmospheric pressure -- that passes through the target material. The waves are so powerful that they turn solids into liquids, liquids into gases, and gases into plasmas in the same way that heat melts ice to water or boils water into steam.

forgive my ignorance, but how in the hell do they shield themselves from and effectively measure such heats? wouldn't that break down any known material within 100 yards?
The instantaneous energy generated by the device is, of course, freaking huge [a scientific term]. The average energy, i.e. when averaged over the repetition rate of the experiment is not very much at all.

Other than the fact your headline is totally erroneous, this is a nice article. A better story though is available at:

First, the radiated x-ray output was as much as four times the expected kinetic energy input.

netbound, would you agree that Technological growth is growing at an exponential rate now?

Growth is definitely exponential, but the exponents are probably not whole numbers--considered on a year to year basis, just decimal increases as yet. Getting faster all the time though and it's exciting as hell to watch.

I would also like to take this time to say that I believe that there is a current nano fad which places improper assumptions on the advancement (current assesment) of technology. Truthfully, I wouldn't mind seeing the nano fad collapse in favor of a return to science.

But we must be careful as to what technology is increasing. Technology increasing exponentially means almost nothing to me, it could be military hardware/software meant to help the CIA kill another thousand people which is increasing. Nothing I am interested in.
