That's 1,000 times more than the entire rest of the United States was using at the time. It is the highest-energy laser shot ever fired in real life, although some fictional lasers have exceeded the record. The NIF's ultimate goal is to induce nuclear fusion in a highly compressed pellet of hydrogen, which will be held at the target point of the laser beams. The fusion reaction will generate energy, so we'll earn back our 500 terawatts with interest.[/quote] [url]http://www.popsci.com/technology/article/2012-07/national-ignition-facility-cranks-laser-record-500-trillion-watts[/url] damn
Wow that's pretty awesome
Now make it a gun god damn it.
[I]pew pew [/I][editline]asda[/editline] whats with the robot guy in the comments trying to make this political....

MUAHAHAHA

Im more interested in the [Quote]The fusion reaction will generate energy, so we'll earn back our 500 terawatts with interest.[/quote] Spending money to make money, except with energy.
That gives me an idea. I'm going to write a very short story where a laser fires infinity watts. Then I'll have the world record for largest fictional laser ever fired.
Whenever I see 'scientists X' in the news section I get excited Science is amazing
its not really one laser if its 192 separate lasers is it.

I don't care much about the laser more than I care about what is is trying to accomplish. I think this project is quite interesting.
Where do you source 500 terawatts from!?
[QUOTE=winsanity;36796132]Where do you source 500 terawatts from!?[/QUOTE] I don't know but I'm sure glad I don't have to pay the US energy bill.
[QUOTE]The fusion reaction will generate energy, so we'll earn back our 500 terawatts with interest.[/QUOTE] I like where this is going.
The lasers are only powered for a fraction of a second iirc so it isn't insanely high I remember reading something about this

[QUOTE=BlazeFresh;36796007]its not really one laser if its 192 separate lasers is it.[/QUOTE] I believe they just mean 192 emitters which point at the same target, and as they are probably close together it is just one 'fat' laser, with the power of 192 smaller ones.
The National Ignition Facility is basically the coolest name for a facility ever "So you work at the National Ignition Facility?" "Yeah" "What do you guys do over there?" "Light shit on fire"

[URL="http://en.wikipedia.org/wiki/Joule#Kilojoule"]they're not gonna destroy the power grid any time soon[/URL]
[QUOTE=Sam Za Nemesis;36795981][media]http://www.youtube.com/watch?v=KIuYY6YckVg[/media][/QUOTE] holy shit you can buy it for 1.1K
[QUOTE=winsanity;36796132]Where do you source 500 terawatts from!?[/QUOTE] given that it's about 1500 joules an AC outlet and a motherfucker of a capacitor will do I suppose [editline]16th July 2012[/editline] [QUOTE=BlazeFresh;36796007]its not really one laser if its 192 separate lasers is it.[/QUOTE] ... each of which is 5.2 times as powerful as the entire rest of the united states for a fraction of a second. Still pretty impressive sounding.
[QUOTE=Sam Za Nemesis;36795981][media]http://www.youtube.com/watch?v=KIuYY6YckVg[/media][/QUOTE] I wonder what would happen if you aimed it at your hand
So what would happen to different materials or people if they stood in front of the tip?
[QUOTE=winsanity;36796132]Where do you source 500 terawatts from!?[/QUOTE] The 500 terawatts were stored in a lot of capacitors
[QUOTE=Thom12255;36797044]So what would happen to different materials or people if they stood in front of the tip?[/QUOTE] Just going to assume something like what happened to [url=http://en.wikipedia.org/wiki/Anatoli_Bugorski]Anatoli Bugorski[/url]
[QUOTE=Sam Za Nemesis;36795981][media]http://www.youtube.com/watch?v=KIuYY6YckVg[/media][/QUOTE] What happens if you shoot somebody with that thing?
[QUOTE=Saza;36796201]The lasers are only powered for a fraction of a second iirc so it isn't insanely high I remember reading something about this[/QUOTE]Something like a millionth of a second iirc, so the power used isn't anywhere near the total US power consumption, it just would be if it had lasted a full second.
