Bilk\u00f8rsel fik et helt nyt udtryk, da hollandske studerende brugte rumteknologi til at bygge Nuna, den ultimative bil til det 21. \u00e5rhundredest<\/sup> \u00e5rhundrede.<\/p>\n<\/div>\n

Nuna vandt f\u00f8rstepladsen i World Solar Challenge 2001, et 3 010 km langt l\u00f8b p\u00e5 tv\u00e6rs af Australien for solcelledrevne biler. Den satte fire verdensrekorder og gennemf\u00f8rte l\u00f8bet p\u00e5 32 timer og 39 minutter med en gennemsnitshastighed p\u00e5 91 km\/t. Derefter vandt den l\u00f8bet igen i 2003 \u2013 og slog endnu en gang alle rekorder.<\/p>\n

Den str\u00f8mlinede maskine havde mange fordele. Den ydre skal var udformet med henblik p\u00e5 at mindske luftmodstanden og var fremstillet af rumalderplast for at sikre, at den var let og samtidig st\u00e6rk. Hovedkroppen var fremstillet af kulfiber forst\u00e6rket med Kevlar, et materiale, der anvendes i satellitter.<\/p>\n

Bilens overflade var d\u00e6kket af meget effektive solceller af galliumarsenid, som oprindeligt blev udviklet til satellitter som f.eks. ESA\u2019s m\u00e5neudforskningssonde SMART-1. Nuna var ogs\u00e5 udstyret med sm\u00e5 enheder, der sikrede maksimal ydelse fra batteriet og solcellerne, selv n\u00e5r bilen stod i skygge, eller vejret var overskyet. Disse enheder anvendes p\u00e5 mange satellitter, s\u00e5som ESA\u2019s kometj\u00e6ger Rosetta.<\/p>","protected":false},"excerpt":{"rendered":"
