IMPULSO SOLAR - Avião movido a energia solar faz voo noturno

O avião experimental Solar Impulse HB-SIA, se tornou  a primeira aeronave tripulada que funciona apenas com energia solar a fazer um voo superior a 24 horas, incluindo o período noturno.
O voo durou 26 horas. As asas leves, de fibra de carbono, dominam a aeronave: é lá que estão as 12 mil células fotovoltaicas, que absorvem a energia do Sol, que é convertida em energia, armazenada em pilhas de lítio, semelhantes às dos automóveis elétricos. Essa energia tem de ser gerida pelo piloto durante a noite, até voltar o Sol, planando e aproveitando as correntes - como um inseto que se deixa levar no vento.

  2. Muito bom esse trabalho para se usar energia limpa.Ainda se está engatinhando mas,quem viver verá.
    O voo do protótipo aí,me lembrou o 14bis... e,acho que é assim mesmo que será visto no futuro,como vemos e até rimos dos "apetrechos" de um século atrás.

  3. Hey I know this is off topic but I was wondering if you knew of any widgets I
    could add to my blog that automatically tweet my newest
    twitter updates. I've been looking for a plug-in like this for quite some time and was hoping maybe you would have some experience with something like this. Please let me know if you run into anything. I truly enjoy reading your blog and I look forward to your new updates.
