El mundo del autom\u00f3vil adquiri\u00f3 una nueva dimensi\u00f3n cuando unos estudiantes holandeses utilizaron tecnolog\u00eda espacial para construir \u00abNuna\u00bb, el coche definitivo para el siglo XXI.st<\/sup> siglo.<\/p>\n<\/div>\n

Nuna acab\u00f3 primero en la competici\u00f3n 2001 World Solar Challenge, una carrera de 3.010 km a trav\u00e9s de Australia para coches alimentados por energ\u00eda solar. El Nuna rompi\u00f3 cuatro r\u00e9cords mundiales, finalizando la carrera en 32 horas 39 minutos a una velocidad promedio de 91 km\/h. Posteriormente volvi\u00f3 a ganar esa misma carrera en 2003, pulverizando nuevamente todos los r\u00e9cords.<\/p>\n

Era una m\u00e1quina estilizada y con muchas ventajas. Se hab\u00eda dise\u00f1ado para reducir la resistencia al aire y la cubierta exterior era de pl\u00e1sticos de la era espacial, para restarle peso y a\u00f1adirle resistencia. La carrocer\u00eda era de fibra de carbono reforzada con Kevlar, un material utilizado en los sat\u00e9lites.<\/p>\n

La superficie del coche estaba recubierta de c\u00e9lulas solares de arseniuro de galio muy eficientes, desarrolladas inicialmente para sat\u00e9lites como el explorador lunar SMART-1 de la ESA. El Nuna tambi\u00e9n llevaba peque\u00f1os dispositivos que garantizaban el m\u00e1ximo rendimiento de su bater\u00eda y de las c\u00e9lulas solares, incluso cuando el coche se encontraba a la sombra o el tiempo estaba nublado. Estos dispositivos se utilizan en muchos sat\u00e9lites, como la sonda Rosetta de la ESA, destinada a la exploraci\u00f3n de cometas.<\/p>","protected":false},"excerpt":{"rendered":"
