Bilk\u00f6rningen fick en helt ny dimension n\u00e4r nederl\u00e4ndska studenter anv\u00e4nde rymdteknik f\u00f6r att bygga Nuna, den ultimata bilen f\u00f6r 21st<\/sup> \u00e5rhundradet.<\/p>\n<\/div>\n

Nuna kom p\u00e5 f\u00f6rsta plats i World Solar Challenge 2001, ett 3 010 km l\u00e5ngt lopp tv\u00e4rs \u00f6ver Australien f\u00f6r solcellsdrivna bilar. Den slog fyra v\u00e4rldsrekord och avslutade loppet p\u00e5 32 timmar och 39 minuter med en genomsnittshastighet p\u00e5 91 km\/h. D\u00e4refter vann den loppet igen 2003 \u2013 och slog \u00e5terigen alla rekord.<\/p>\n

Den str\u00f6mlinjeformade maskinen hade m\u00e5nga f\u00f6rdelar. Det yttre h\u00f6ljet, som var utformat f\u00f6r att minska luftmotst\u00e5ndet, var tillverkat av rymdteknisk plast f\u00f6r att g\u00f6ra den b\u00e5de l\u00e4tt och stark. Huvuddelen bestod av kolfiber f\u00f6rst\u00e4rkt med Kevlar, ett material som anv\u00e4nds i satelliter.<\/p>\n

Bilens yta var t\u00e4ckt av mycket effektiva solceller av galliumarsenid, som ursprungligen utvecklades f\u00f6r satelliter som ESA:s m\u00e5nsond SMART-1. Nuna var \u00e4ven utrustad med sm\u00e5 enheter som s\u00e4kerst\u00e4llde maximal effekt fr\u00e5n batteriet och solcellerna, \u00e4ven n\u00e4r bilen befann sig i skuggan eller vid molnigt v\u00e4der. Dessa enheter anv\u00e4nds p\u00e5 m\u00e5nga satelliter, till exempel ESA:s kometj\u00e4gare Rosetta.<\/p>","protected":false},"excerpt":{"rendered":"
