V jednoduchosti by sa dal cel\u00fd syst\u00e9m op\u00edsa\u0165 tak \u017ee cez tenk\u00fa vrstvu hrdze pretek\u00e1 slan\u00e1 voda a je to. Ak by si niekto myslel \u017ee sa jedn\u00e1 o \u010fal\u0161\u00ed chemick\u00fd zdroj energie tak ho budeme musie\u0165 opravi\u0165. Preto\u017ee v tomto pr\u00edpade sa sk\u00f4r bav\u00edme o elektrokinetickej v\u00fdrobe elektriny. Je to z toho d\u00f4vodu \u017ee tu nep\u00f4sobia chemick\u00e9 reakcie v klasickom slova zmysle ale u\u017e spomenut\u00e9 kinetick\u00e9. Tento princ\u00edp v\u00fdroby elektriny nie je ni\u010d\u00edm nov\u00fdm. U\u017e d\u00e1vno bol pozorovan\u00fd podobn\u00fd pr\u00edpad pri pou\u017eit\u00ed graf\u00e9mu. Jeho \u00fa\u010dinnos\u0165 bolo len okolo 30% , \u010do je vzh\u013eadom k jeho cene ve\u013emi neekonomick\u00e9.\u00a0 Len pre porovnanie tak najv\u00fdkonnej\u0161ie sol\u00e1rne panely dok\u00e1\u017eu za optim\u00e1lnych podmienok dosahova\u0165 \u00fa\u010dinnos\u0165 20% a tak je jasn\u00e9 \u017ee tento nov\u00fd sp\u00f4sob v\u00fdroby energie si u\u017e n\u00e1jde svojich priaznivcov.\u00a0S\u00edce to mohlo znie\u0165 na prv\u00e9 po\u010dutie \u017ee je to \u00faplne jednoduch\u00e9. Skuto\u010dnos\u0165 je e\u0161te st\u00e1le vzdialen\u00e1 re\u00e1lnemu nasadeniu. Preto\u017ee aby to mohlo re\u00e1lne cel\u00e9 fungova\u0165. Mus\u00edme dosiahnu\u0165 tenk\u00fa zoxidovan\u00fa vrstvu \u017eeleza \u201ehrdzu\u201c. Cez ktor\u00fa bude slan\u00e1 voda preteka\u0165. Dosiahneme to takzvane fyzik\u00e1lnym princ\u00edpom\u00a0 naparovania. \u010ci\u017ee vytvor\u00edme tenk\u00fa vrstvu po\u017eadovan\u00e9ho zoxidovan\u00e9ho \u017eeleza a n\u00e1sledne to cele cez neho pre\u017eenieme. Pod\u013ea v\u00fdpo\u010dtov vedcov vrstva o sile 10 manometrov dok\u00e1\u017ee vyprodukova\u0165 nieko\u013eko milivoltov elektriny. To zasa nie je ni\u010d moc. Ale ak by cel\u00fd tento syst\u00e9m mal u\u017e rozlohu aspo\u0148 10 metrov. Bolo my mo\u017en\u00e9 bez v\u00e4\u010d\u0161\u00edch probl\u00e9mov z\u00e1sobova\u0165 priemern\u00fa dom\u00e1cnos\u0165 a to je u\u017e celkom zauj\u00edmav\u00e9 aj z komer\u010dn\u00e9ho h\u013eadiska. A tak uvid\u00edme \u010di sa n\u00e1jde niekto kto si na to tr\u00fafne alebo nie.                                                                                                                                                                                                                                                                                                                                                                                        4.1\/5 - (7 votes)        "},{"@context":"https:\/\/schema.org\/","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Vedci dok\u00e1zali vyrobi\u0165 elektrinu za pomoci hrdze","item":"https:\/\/www.rohau.sk\/vedci-dokazali-vyrobit-elektrinu-za-pomoci-hrdze\/#breadcrumbitem"}]}]
