This is the Sandia National Laboratories' Z machine discharging AFTER firing.It's basically a huge bank of capacitors, which all fire into a tiny cylinder of human hair sized wires.

It has an output power of about 290 trillion watts, which is for nanosecends, about 80 times the entire world's output of electricity.It has reached temps of 1.6 million°C(2.9 million°F), the surface temp of Sun is about 6000°C(11000°F).According to Sandia's website, it runs off "normal wall current".

It has also been used to propel a tiny plate of aluminum to over 76,000 MPH in less than a second, an acceleration of about 10 billion Gs.When the plate hits it's target, it produces a shockwave of about 217.5 million PSI.

There are plans for the X-1, a larger accelerator scheduled to follow Z, that should be able to produce more than 1,000 trillion watts of power, and temperatures of more than 3 million degrees.
