Man-made Star to Unlock Cosmic Secrets

"When the world's most powerful laser facility flicks the switch on its first full-scale experiments later this month, a tiny star will be born on Earth."

The World's Biggest Laser Powers Up

Now complete, the National Ignition Facility could soon create controlled fusion using lasers.






The most energetic laser system in the world, designed to produce nuclear fusion--the same reaction that powers the sun--is up and running. Within two to three years, scientists expect to be creating fusion reactions that release more energy than it takes to produce them. If they're successful, it will be the first time this has been done in a controlled way--in a lab rather than a nuclear bomb, that is--and could eventually lead to fusion power plants.

The National Ignition Facility (NIF), at the U.S. Department of Energy's Lawrence Livermore National Laboratory (LLNL), comprises 192 lasers that fire simultaneously at precisely the same point in space: a sphere of fuel two millimeters in diameter. They are designed to deliver 1.8 megajoules of energy in a few billionths of a second. That's enough to compress the fuel to a speck 50 micrometers across and heat it up to three million degrees Celsius. The lasers, which were fired together for the first time last month, have so far produced pulses of 1.1 megajoules.

"Depending on how you count it, it's between 60 and 100 times more energetic than any laser system that's ever been built," says Edward Moses, the principle associate director for NIF and Photon Science at LLNL. Eventually, the fusion reactions produced by each pulse are expected to generate at least 10 times the energy delivered by the lasers, a significant net gain that could be useful for generating power.

The $3.5 billion facility, which has been in development for 15 years, was funded primarily as a way to better understand nuclear weapons, after a ban on testing in the 1990s. NIF will produce tiny thermonuclear explosions that give scientists insight into what happens when a nuclear bomb goes off. That data can, in turn, be used to verify computer simulations that help determine whether the United States' nuclear stockpile will continue to work as the weapons age. The data could also provide insight into the processes that power the sun and other stars, and answer other scientific questions. Finally, NIF could serve as a proof-of-concept design for a fusion power plant.

what if something goes wrong in this facility? it would also lead to a way too powerful explosion i guess..

Thank you very much for the topic merge.

mura nag star wars....naay death star..hehee

[15% Discount]

layo ra kaayo bro sa tinood mata na kai nag damgo raka..........

[bugztronic]

paita kon naa ni laing side effects after nila na mabuhat ng MAN MADE STAR

dili kaha na mo create ug CATASTROPHE unya muresulta na noon sa extension sa ato cilization?

Ok rama ng ila expirement as long as dili dre sa earth adto lang unta sa laing planets

This is only OUR HOME EARTH and WE ARE ONLY ""DOTS"" If things can HAPPEN.

[jerk1969]

mao sad..dili man jud ma 100% sure na safe jud ni sa ato EARTH..pero it could a great leap for us, mankind, na naa miniature version sa stars where ato ra ma studihan..kuyawa jud sa mga humans oi..hehehe

if the star dies black hole patay GG nata tanan
