Bilkj\u00f8ring fikk et helt nytt uttrykk da nederlandske studenter brukte romfartsteknologi til \u00e5 bygge Nuna, den ultimate bilen for det 21.st<\/sup> \u00e5rhundre.<\/p>\n<\/div>\n

Nuna kom p\u00e5 f\u00f8rsteplass i World Solar Challenge 2001, et 3 010 km langt l\u00f8p tvers over Australia for solcelledrevne biler. Den satte fire verdensrekorder og fullf\u00f8rte l\u00f8pet p\u00e5 32 timer og 39 minutter med en gjennomsnittsfart p\u00e5 91 km\/t. Deretter vant den l\u00f8pet igjen i 2003 \u2013 og knuste nok en gang alle rekorder.<\/p>\n

Den str\u00f8mlinjeformede maskinen hadde mange fordeler. Det ytre skallet var utformet for \u00e5 redusere luftmotstanden og var laget av romalderplast for \u00e5 gj\u00f8re den lett, men likevel sterk. Hoveddelen var laget av karbonfiber forsterket med Kevlar, et materiale som brukes i satellitter.<\/p>\n

Bilens overflate var dekket av sv\u00e6rt effektive solceller av galliumarsenid, som opprinnelig ble utviklet for satellitter som ESAs m\u00e5neutforsker SMART-1. Nuna hadde ogs\u00e5 med seg sm\u00e5 enheter som sikret maksimal ytelse fra batteriet og solcellene, selv n\u00e5r bilen sto i skyggen eller det var overskyet. Slike enheter brukes p\u00e5 mange satellitter, for eksempel ESAs kometjeger Rosetta.<\/p>","protected":false},"excerpt":{"rendered":"
