19 million Amps

deblau writes "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)."

    I did the math for everyone... it works out to One point twenty one jiga-watts, Marty!

    Um....unless things have changed in the 25+ years since I took a college physics class, we measure POWER in WATTS, and CURRENT in AMPS. So the number you quoted in AMPS that you claims is eqaual to four times the POWER in amps doesn't make any sense. Of course, that never stopped our /. Editors before!

    Where did they do this experiment--Mars?

  4. 11? by ryanvm · · Score: 5, Funny

    I'll bet this amp goes to 11.

    From later in TFA: "During the few milionths of a second that it operates, Atlas generates electrical energy roughly four times the Earth's entire energy production."

    This is almost technically right except for "Atlas generates"... Atlas is only a huge capacitor bank, it does not magically "generate" energy, it only stores existing energy.

    Now, if worldwide production is something like 25GW and the pulse lasts 10us, we have 25GW * 4 * 10us = 1MJ, a balievable finite quantity.

  6. 19 million Amperes is chicken feed by Anonymous Coward · · Score: 5, Informative

    My home electric stove+oven has 2x 50A circuit breakers; my electric water heater, 2x 40A; my electric clothes dryer, 2x 30A (all 230V service in US). There are at least 15 million houses in the US with similar electrical service. Some industrial plating baths use 6000 Amperes at less than 3V. So 19 million amps is a serious underestimate of the current being used in the world.
