1.21 Jigawatts!
Straight from Slashdot:
“On July 27, scientists at the National Nuclear Security Administration’s Nevada Test Site said they generated a current equal to about four times all the electrical current on Earth. During the few millionths of a second that it operated, the 650-ton Atlas pulsed-power generator discharged about 19 million amps of current through an aluminum cylindrical shell about the size of a tuna can. Official news release is available from the DOE (PDF).”
INSANE.
Maybe that is enough power for a flux capacitor to send a De Lorean back to November 5, 1955
