Za ustrezno delovanje pa mora biti ravno obratno, pi\u0161e na spletni strani nizozemske neprofitne organizacije The Ocean Cleanup.<\/p>\n<h2>Sistem \u0161e ne deluje dovolj u\u010dinkovito<\/h2>\n<p>Sistem bi lahko upo\u010dasnjevalo nihanje obeh koncev dveh 600 metrov dolgih plasti\u010dnih cevi, ki sta postavljeni v obliki \u010drke U. Do nihanja prihaja zaradi sile vetra. To nihanje pa ima pri gibanju sistema ravno nasprotni u\u010dinek kot veter. Poleg tega je mo\u017eno \u0161e, da to nihanje ustvarja rahlo valovanje, kar odna\u0161a plastiko.<\/p>\n<p>V preteklih testiranjih tega niso predvideli, tako da tudi niso imeli takoj\u0161nje re\u0161itve. Odlo\u010dili so se, da bodo hitrost sistema pove\u010dali tako, da bodo razpon postavitve raz\u0161irili za med 60 in 70 metrov. S tem se bo namre\u010d pove\u010dala povr\u0161ina, ki je izpostavljena vetru in valovom, ki poganjata sistem. Z raz\u0161iritvijo pa se bo zmanj\u0161al tudi upor, ki ga povzro\u010data konca obeh cevi, saj ne bosta ve\u010d naravnost v smeri gibanja sistema.<\/p>\n<p>Razpon bodo raz\u0161irili v ve\u010d korakih, dokler ne bodo dosegli \u017eelenega u\u010dinka. Vendar pa bodo morali biti pri tem pazljivi, da ga ne bodo raz\u0161irili preve\u010d, saj bo to negativno vplivalo na zmo\u017enost sistema pri hitrem obra\u010danju, ko veter spremeni smer.<\/p>\n<p>Ladja s tem sistemom je iz pristani\u0161\u010da v San Franciscu odplula v za\u010detku septembra, pri \u010demer so jo najprej testirali na obmo\u010dju pribli\u017eno 350 navti\u010dnih milj zahodno od ameri\u0161ke obale. Nato se je odpravila proti plavajo\u010demu otoku plasti\u010dnih odpadkov, imenovanem tudi velika pacifi\u0161ka zaplata odpadkov, ki je pribli\u017eno 1300 navti\u010dnih milj zahodno od obale. Tam so sistem uspe\u0161no namestili sredi oktobra.<\/p>\n<p>Sistem je sestavljen iz dveh 600 metrov dolgih plasti\u010dnih cevi, napolnjenih z zrakom. Pod cevmi je ponjava, ki sega tri metre globoko. Na Tihi ocean so poslali prvega od skupno petih sistemov projekta The Ocean Cleanup.<\/p>\n<p>Otok odpadkov se razteza \u017ee na 1,6 milijona kvadratnih kilometrih in se \u0161e pove\u010duje. Znanstveniki so ugotovili, da je v oceanskem smeti\u0161\u010du ve\u010d kot 1800 milijard kosov plastike, ki ogro\u017eajo \u017eivljenje v morju.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Sistem za \u010di\u0161\u010denje plasti\u010dnih odpadkov v morju, ki so ga sredi oktobra uspe\u0161no namestili v Tihem oceanu, se soo\u010da s te\u017eavami.
