presnejsie povedane vzniklo pri fuzii viac energie ako vyziaril laser. problemy:
1. efektivita lasera je << 100%
2. nepodarilo sa nic ziskat (to ani nebol ciel, ale skonvertovat na vyuzitelnu elektrinu aj cast uvolnenej energie je obrovsky problem)

cize sme este velmi daleko od rozumneho vyuzitia. a aj tak si myslim ze ITER je perspektivnejsi :)

..ITER began in 1985 as a Reagan – Gorbachev initiative with the equal participation of the Soviet Union, European Union (through EURATOM), the USA, and Japan through the 1988–1998 initial design phases.

znamena to, ze realne energia z fuzie < nez energia dodana na zacatie fuzie?
energia, ktoru ta fuzia vytvorila, by nedokazala sama zafinancovat jej zacatie?
porovnavaju len cisto izolovane hodnoty, energia fuzie vs energia vzniknuta na spicke laseroveho dela? vylucili energeticke naklady na nazhavenie dela atd. atd.?

ano
The input to the lasers is 422 MJ. The output is 1.8 MJ. So if the input/output was ~1.8 MJ, then the system as a whole is operating at about 0.4% of break even.

cize v podstate sa jedna o dokaz, ze fuziu mozno "vyrobit" ludskymi prostriedkami, ale treba to este doladit, nech output energy > input energy a teda nech ma fuzia vobec prakticky zmysel?

0000010100063533052119940735530107355598073556560735584807356474073564790735648407356497

Podla toho co je prakticky zmysel. Vodikova bomba je tiez fuzna :)
Zariadenie s kontrolovanou fuziou (ci uz laser, tokamak alebo co) a (stabilnym, prakticky vyuzitelnym) kladnym energetickym vysledkom aktualne myslim neexistuje, ale teoreticky mozne je, preto sa stavia ITER a pod.

parada, diky. pozrem si nejaky dokument o iteri

a este aby sa ta facilita mohla volat Ignition tak by tiez mala nejaka nastat, co sa vraj nedeje :)

tu je celkom fajn vysvetlenie: http://hardware.slashdot.org/comments.pl?sid=4311489&cid=45068225

hej uz som niekde cital ze ak nevyjde nevadi, aspon sa ziskaju poctive data na vyskum buducich bomb

..ICF is a jobs program for engineers who got scared as hell when the cold-war ended and started pimping their bomb-research machines to environmentalists who don't understand physics or economics.

dobra bomba nie je zla : )
