Lumea automobilelor a c\u0103p\u0103tat o cu totul alt\u0103 fa\u021b\u0103 atunci c\u00e2nd ni\u0219te studen\u021bi olandezi au folosit tehnologia spa\u021bial\u0103 pentru a construi Nuna, ma\u0219ina ideal\u0103 pentru secolul 21st<\/sup> secol.<\/p>\n<\/div>\n

Nuna a terminat pe primul loc \u00een cadrul World Solar Challenge din 2001, o curs\u0103 de 3 010 km care traverseaz\u0103 Australia, destinat\u0103 ma\u0219inilor alimentate cu energie solar\u0103. A dobor\u00e2t patru recorduri mondiale, termin\u00e2nd cursa \u00een 32 de ore \u0219i 39 de minute, cu o vitez\u0103 medie de 91 km\/h. Apoi a c\u00e2\u0219tigat din nou cursa \u00een 2003 \u2013 dobor\u00e2nd \u00eenc\u0103 o dat\u0103 toate recordurile.<\/p>\n

Ma\u0219ina cu design aerodinamic prezenta numeroase avantaje. Conceput\u0103 pentru a reduce rezisten\u021ba la aer, carcas\u0103 exterioar\u0103 era realizat\u0103 din materiale plastice de ultim\u0103 genera\u021bie, pentru a asigura o greutate redus\u0103, dar \u0219i o rezisten\u021b\u0103 ridicat\u0103. Corpul principal era fabricat din fibr\u0103 de carbon \u00eent\u0103rit\u0103 cu Kevlar, un material utilizat la construc\u021bia sateli\u021bilor.<\/p>\n

Suprafa\u021ba ma\u0219inii era acoperit\u0103 cu celule solare foarte eficiente din arseniur\u0103 de galiu, dezvoltate ini\u021bial pentru sateli\u021bi precum sonda lunar\u0103 SMART-1 a ESA. Nuna era echipat\u0103, de asemenea, cu dispozitive mici care asigurau o putere maxim\u0103 a bateriei \u0219i a celulelor solare, chiar \u0219i atunci c\u00e2nd ma\u0219ina se afla la umbr\u0103 sau c\u00e2nd cerul era \u00eennorat. Aceste dispozitive sunt utilizate pe numero\u0219i sateli\u021bi, cum ar fi sonda Rosetta a ESA, destinat\u0103 explor\u0103rii cometei.<\/p>","protected":false},"excerpt":{"rendered":"
