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)."

    In operation, the 650-node Slashdot news-for-nerds generator successfully discharged nearly 19 million hits of HTTP requests through the NNSA Nevada Site Office News webpage, or PDF, on a server about the size and shape of a tuna can. The requests caused the server to implode at extreme speeds, with unrivaled symmetry, precision, and reproducibility.

      That would require about 64 volts of potential across the target at the stated current, at a resistance of 3.3 micro-ohms of resistance in the target.

      Given the "few millionths of a second" duration, the total energy would be about a kilo-joule to ten kilo-joules - about the same as the chemical energy in a single gumdrop (there's a new /unit for you!)

    "about four times all the electrical power on Earth"
    Wouldn't that be all of the OTHER power on Earth? After all, this test was conducted on Earth, making even this discharge a subset of the "all the electrical power on Earth," but I digress. It's really amazing, though, to think this was pulse through a tuna-can sized hunk of aluminum. You'd think it melt. Tuna...melt....I really should stop.

    I think tuna can be cooked with far less power.

    Tuna can be cooked with much less power, but unforunately by slow cooking it you lose a lot of the natural flavoring. That's why this, the preferred solution by most gourmet chefs, cooks the tuna in a few millionths of a second.
