Autoilu sai aivan uuden ilmeen, kun hollantilaiset opiskelijat rakensivat avaruusteknologiaa hy\u00f6dynt\u00e4en Nunan, 21. vuosisadan huippuautonst<\/sup> vuosisata.<\/p>\n<\/div>\n

Nuna sijoittui ensimm\u00e4iseksi vuoden 2001 World Solar Challengessa, joka oli 3 010 km:n pituinen, koko Australian halki kulkeva aurinkovoimalla toimivien autojen kilpailu. Se rikkoi nelj\u00e4 maailmanenn\u00e4tyst\u00e4 ja ajoi kilpailun loppuun 32 tunnissa ja 39 minuutissa keskinopeudella 91 km\/h. Sen j\u00e4lkeen se voitti kilpailun uudelleen vuonna 2003 \u2013 j\u00e4lleen rikkoen kaikki enn\u00e4tykset.<\/p>\n

Aerodynaamisella koneella oli monia etuja. Ilmanvastusta v\u00e4hent\u00e4v\u00e4\u00e4n muotoon suunniteltu ulkokuori oli valmistettu avaruusteknologian mukaisista muoveista, jotta se olisi kevyt mutta silti kest\u00e4v\u00e4. Runko oli valmistettu hiilikuidusta, jota oli vahvistettu Kevlarilla, materiaalilla, jota k\u00e4ytet\u00e4\u00e4n satelliiteissa.<\/p>\n

Auton pinta oli peitetty eritt\u00e4in tehokkailla galliumarsenidipohjaisilla aurinkokennoilla, jotka oli alun perin kehitetty satelliiteille, kuten ESA:n SMART-1-kuututkimusluotaimelle. Nuna kuljetti mukanaan my\u00f6s pieni\u00e4 laitteita, jotka takasivat akun ja aurinkokennojen maksimaalisen tehon jopa silloin, kun auto oli varjossa tai s\u00e4\u00e4 oli pilvinen. N\u00e4it\u00e4 laitteita k\u00e4ytet\u00e4\u00e4n monissa satelliiteissa, kuten ESA:n Rosetta-komeettatutkimusluotaimessa.<\/p>","protected":false},"excerpt":{"rendered":"
