Munje koje tra\u017ee put najmanjeg otpora izme\u0111u oblaka i tla privu\u010de taj kanal pun nabijenih elektrona.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ideja o kori\u0161tenju lasera za\u0161tite od munja datira jo\u0161 iz 70-ih godina, ali do sada su znanstvenici nailazili na izazove u primjeni ove ideje u stvarnim uvjetima. Klju\u010dni problem bio je odr\u017eavanje kanala otvorenog dovoljno dugo kako bi privukao munje tijekom oluje.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Znanstvenici su razvili laserski sustav koji je mogao ispaljivati \u200b\u200bimpulse velike snage do 1000 puta u sekundi, \u010dime je znatno pove\u0107ana vjerojatnost za privla\u010denje munje. Na vrhu 2500 metara visoke planine S\u00e4ntis u \u0160vicarskoj postavili su ovu opremu kako bi je testirali.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/otpor.media\/wp-content\/uploads\/2023\/10\/munje-2-071023-1024x568.jpg\" alt=\"\" class=\"wp-image-41745\" \/><\/figure>\n\n\n\n<p class=\"has-luminous-vivid-orange-color has-text-color wp-block-paragraph\"><strong>Laseri su budu\u0107nost?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Kako bi uspje\u0161no testirali novu opremu, znanstvenici su je postavili na mjesto gdje se \u010desto javljaju munje. Laseri su se aktivirali kad god je bila najavljena grmljavinska oluja. Kona\u010dno su zabilje\u017eili prirodnu munju koja je pratila lasersku zraku prije nego \u0161to je pogodila ciljani toranj.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Iako gromobrani, izumljeni od strane Benjamina Franklina, ostaju naju\u010dinkovitiji na\u010din za\u0161tite od munja do visine njihove visine, njihova za\u0161tita ne dose\u017ee visoko u oblake. Nasuprot tome, laserski sustav mo\u017ee dose\u0107i visoko u oblake, pro\u0161iruju\u0107i radijus za\u0161tite od munje.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ovaj napredak otvara mogu\u0107nost da bi laseri jednog dana mogli postati klju\u010dna komponenta za\u0161tite od munja, posebno za visoke objekte koji nisu dovoljno za\u0161ti\u0107eni tradicionalnim gromobranima.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Unato\u010d zna\u010dajnom napretku, stru\u010dnjaci upozoravaju da \u0107e pro\u0107i najmanje deset godina prije nego \u0161to ovakva tehnologija bude dovoljno razvijena da postane dostupna na tr\u017ei\u0161tu. Me\u0111utim, ovaj uspjeh otvara obe\u0107avaju\u0107u perspektivu u borbi protiv opasnih munja i grmljavinskih oluja koje svake godine uzrokuju \u0161tetu i gubitke \u017eivota.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><a href=\"https:\/\/www.sciencealert.com\/for-the-first-time-scientists-have-bent-lightning\">Sciencealert.com<\/a><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Znanstvenici su postigli zna\u010dajan napredak u suzbijanju munja pomo\u0107u sna\u017enog laserskog zra\u010denja, otvaraju\u0107i potencijal za novu metodu za\u0161tite od opasnih grmljavinskih oluja.
