Cercet\u0103torii exploreaz\u0103 o metod\u0103 radical\u0103 de a genera electricitate din energia solar\u0103 chiar \u0219i dup\u0103 apus, scrie CNN<\/a><\/span>.<\/p>\n

Cunoscut\u0103 drept \u201eenergia solar\u0103 nocturn\u0103\u201d, aceast\u0103 tehnologie ar putea alimenta sateli\u021bii \u00een perioadele de \u00eentuneric, reduc\u00e2nd dependen\u021ba de baterii.<\/p>\n

Transformarea c\u0103ldurii \u00een electricitate dup\u0103 apus<\/h2>\n

Oamenii de \u0219tiin\u021b\u0103 de la Universitatea din New South Wales dezvolt\u0103 dispozitive care func\u021bioneaz\u0103 ca panouri solare inverse.<\/p>\n

\u00cen loc s\u0103 absoarb\u0103 lumina soarelui, acestea produc electricitate prin emiterea radia\u021biei infraro\u0219ii eliberate de P\u0103m\u00e2nt pe timpul nop\u021bii.<\/p>\n

Procesul se bazeaz\u0103 pe un dispozitiv semiconductor numit diod\u0103 termoradiativ\u0103, capabil s\u0103 transforme radia\u021bia infraro\u0219ie \u00een electricitate.<\/p>\n

Pe parcursul zilei, P\u0103m\u00e2ntul absoarbe energia solar\u0103, care este eliberat\u0103 ulterior sub form\u0103 de c\u0103ldur\u0103 dup\u0103 apus.<\/p>\n

Dioda converte\u0219te aceast\u0103 radia\u021bie infraro\u0219ie emis\u0103 \u00een energie electric\u0103.<\/p>\n

Cercet\u0103torii spun c\u0103, de\u0219i ideea se bazeaz\u0103 pe studii anterioare, aceasta reprezint\u0103 prima demonstra\u021bie direct\u0103 a producerii de electricitate utilizabil\u0103 cu ajutorul unui astfel de dispozitiv.<\/p>\n

Putere redus\u0103, poten\u021bial mare \u00een spa\u021biu<\/h2>\n

\u00cen prezent, diodele termoradiative genereaz\u0103 mult mai pu\u021bin\u0103 energie dec\u00e2t panourile solare conven\u021bionale.<\/p>\n

Pe P\u0103m\u00e2nt, eficien\u021ba lor este limitat\u0103 de atmosfer\u0103, care re\u021bine c\u0103ldura \u0219i reduce diferen\u021ba de temperatur\u0103 necesar\u0103 func\u021bion\u0103rii.<\/p>\n

Chiar \u0219i \u00een condi\u021bii optime, cantitatea de energie produs\u0103 r\u0103m\u00e2ne modest\u0103.<\/p>\n

Totu\u0219i, cercet\u0103torii cred c\u0103 adev\u0103ratul poten\u021bial al tehnologiei se afl\u0103 \u00een spa\u021biu.<\/p>\n

F\u0103r\u0103 atmosfer\u0103, sateli\u021bii pot radia c\u0103ldura \u00een medii extrem de reci, cre\u00e2nd condi\u021bii ideale pentru acest tip de generare a energiei.<\/p>\n

\u00cen orbita joas\u0103 a P\u0103m\u00e2ntului, sateli\u021bii alterneaz\u0103 la fiecare 90 de minute \u00eentre lumin\u0103 \u0219i \u00eentuneric, ceea ce face energia solar\u0103 nocturn\u0103 deosebit de util\u0103.<\/p>\n

Dincolo de orbita terestr\u0103 \u0219i misiunile viitoare<\/h2>\n

Cercet\u0103tori de la NASA analizeaz\u0103, la r\u00e2ndul lor, utilizarea diodelor termoradiative \u00een misiuni spa\u021biale \u00eendep\u0103rtate.<\/p>\n

\u00cen aceste contexte, tehnologia ar putea \u00eenlocui generatoarele termoelectrice voluminoase \u0219i costisitoare bazate pe materiale radioactive.<\/p>\n

De\u0219i exist\u0103 \u00eenc\u0103 provoc\u0103ri, inclusiv rezisten\u021ba la temperaturi ridicate, studiile sugereaz\u0103 c\u0103 progrese semnificative sunt posibile \u00een urm\u0103torul deceniu.<\/p>\n

Echipa de la UNSW preg\u0103te\u0219te teste experimentale \u0219i lucreaz\u0103 la materiale mai eficiente.<\/p>\n

Cu finan\u021bare \u0219i dezvoltare continu\u0103, exper\u021bii spun c\u0103 energia solar\u0103 nocturn\u0103 ar putea deveni o solu\u021bie practic\u0103 pentru sistemele satelitare ale viitorului.<\/p>\n","protected":false},"excerpt":{"rendered":"
