Massive electric current tested in US
Aljazeera

The test was part of an operation to test US nuclear capability

Scientists at the Nevada Test Site have said they generated a current equal to roughly four times all the electrical power on Earth.

The current, which created pressures in materials millions of times greater than normal, was part of an experiment to better understand nuclear weapons.

The experiment was conducted on Wednesday at the test site's Atlas Pulsed Power Facility by scientists from Los Alamos National Laboratory in New Mexico, along with staff from the test site and contractor Bechtel Nevada.

19 million amps

During the few millionths of a second that it operated, the 650-ton Atlas pulsed-power generator discharged nearly 19 million amps of current through an aluminum cylindrical shell about the size of a tuna can, the National Nuclear Security Administration said.

Atlas, which works as a giant power multiplier, was designed as part of an Energy Department programme to determine the readiness of the nation's nuclear stockpile without underground testing.

It was built at Los Alamos and recently moved to the Nevada Test Site, a proving ground just north of Las Vegas

And ANOTHER one I missed!

Now I know I've been preoccupied evenings re-reading Harry Potter, but I do read the news every morning and afternoon...at least that which catches my eye and interest. This one would have qualified in both areas!

Guess I'll have to start scanning Aljazeera earlier in the day! <>g

I've got a buddy that works at the Site; gonna have to call him and ask if he worked this one (although I'm sure I'll get the standard answer: "I'm not at liberty to comment on that").

Current equal to power. I'd like to see them perform a "units analysis" on this equation...

Again LOL. Yesterday, our local radio station announced that TECO energy had set an alltime summer demand record of (ta da) 9 megawatt hours. Seems endemic that the media confuses energy, power, voltage, current, etc.

Given that Nevada is part of "the Earth," they generated power equal to roughly four times the power they generated plus all other power on the Earth. Right?

They meant four times the power generated in "regular" power systems on Earth.. excluding their brief experiment which does not count as part of our normal power supply system.

How did they generate 4 times more current than actually exists?

I would love to see what happened to the 'tuna can'. Usually such currents change the shape of the 'wire'.

See http://www.texspec.com/crushed_coin.htm for example.

The guy makes quarters smaller than a dime and sells them for nine bucks. Is that deflation or inflation?

Being as to how the average power plant is probably 500mw/hr and their unit auxillary usage is 20+/mw/hr somebody is off a few decimals.

I was thinking the same thing. I want to know the voltage drop.

BTW, in the good old days when the USA actually developed new technology and used experiments to perfect it rather than computer simulations, I worked with a group who tested reentry materials, primarily for the MX missile system reentry vehicle but also the space shuttle leading edge surfaces. We used to fire a 10 mega Watt arc gun at the target. It was an air plasma jet fired into a supersonic evacuation stream. The target was placed in the path, instrumented with calorimeters and we set up high speed cameras to record data.

The noise, the shock wave, the plasma jet was real cool, even if it only lasted for about five seconds at a time. The problem was twofold, generating a reservoir of low pressure tanks (giant vacuum system) large enough to maintain a supersonic evacuation stream with a two foot opening, and storing enough power to maintain a 10 mega Watt power delivery. There were several thousand deep cycle batteries cabled together in both series and parallel to supply the power with the cables coming out of the buss being internally water cooled. They were like fire hoses.

Facilities like that are few and far between these days.

energy, power, voltage, current

For a reporter, those are synonyms. Varying terms to use at random when writing articles about 'electricity'. These are the kind of people who, when you tell them you are in the sciences, say, "Oh, I always hated that stuff."

Cute, but no substitute for regular underground testing.

I assume they are comparing the peak power to the average power used in the world....Which is like comparing the peak power of your hammer to the average power of your neighborhood grid....Meaningless.

Wait a minute. Power is 'watts' or 'joules/second'. Energy is 'watt seconds or hours'. That's power x time. The unit mw/hr would read 'milliwatts per hour', which is not correct at all. The joule is the unit for energy. A joule/s is a watt.

Electrical generating plants are usually rated in 'megawatts' or 'MW' with a capital M. This is power. Power is only the time RATE at which electical energy is produced/used. You don't buy 'power', you buy 'energy'. Energy is measured in watts times time, or 'watt hours'. This is sometimes written as 'watt-hours' but then some folks think the dash is a minus sign, which it isn't.

A 100 Watt light bulb isn't more 'powerful' than a 60 watt bulb. Things can't 'have' power. They can only 'use' energy at higher or lower rates. 100 Watts means the bulb uses energy at the rate of 100 joules per second. Every second it is on, it uses 100 joules. In one hour, it uses 360 000 joules of energy.

Wait a minute again! 'Peak' implies a rate rather than a total. (Just as 'peak speed' would be measured in 'miles/hour'. Total distance would be speed times time, which gives 'distance'.)

If they wanted to say 'power' they should use 'megawatts'. If they want to say 'energy' they should use 'megawatt hours'. It sounds as if they were talking about power since they mentioned a peak value. This means people were using energy a the highest RATE for the day. They should have said 'megawatts', the proper unit for power, not 'megawatt hours'.

From this reference:

Atlas consists of high voltage capacitor banks that discharge electrical energy into a system of parallel plate transmission lines. Large electrical currents flowing through the plates produce an intense magnetic field, applying a huge pressure pulse into a cylindrical liner and target containing materials of interest. Atlas acts as a giant power amplifier, using energy that accumulates slowly at 480 volts and is stored in the machine's capacitor banks for sudden release into the liner and target. As the electrical current surges through Atlas, it accelerates materials to velocities well in excess of that required to escape Earth's gravity (as high as 22,000 miles per hour), and generates pressures equivalent to millions of times that of Earth's atmosphere. During the few millionths of a second that it is operating at full performance, the tremendous electrical output of Atlas is approximately three to four times that of the world's total electric power production (4 trillion watts)!

LANL and Sandia have been doing this sort of thing for years. Huge currents are pushed through a rounded conductor, and in the process vaporize it. The magnetic field produced by the current drives the plasma radially into a target. The collisions with the target produce considerable radiation. These are device simulators.
