Solar Impulse; The Solar Airplane Flight 2015 (Around The Earth)

I am not certain if in 1999, when Bertrand circled the earth in a balloon, he was setting stage for the Solar Impulse feat or simply it was his Impulse to go Solar! What might have happened in that travel to make him think of a fuel-less flight machine? Whatever the case, it is a project worth emulating! He says, "The pioneer is not always the one who succeeds, but rather the one who is not scared of failing." I believe in his words.
We are here today because of daring men and women, people who went forth to do what they believed in. The common thing about our pioneers is that they go forth to achieve feats for the good of others. The greatest benefits for their pioneering works have gone to others more than themselves. We cannot therefore pretend that the pioneers are the sole beneficiaries of their efforts, we all desire good lives but we all don't have the ability or the know how to change for the better! In 2015, Solar Impulse will be crawling through space at may be 70 KPH.
Perhaps in 2, 060 AD, there will be a solar plane that will be hurtling through space at supersonic speed. Perhaps in 2, 200 AD, there will be solar planes that carry over 300 passengers. Perhaps in 2, 300 AD there will be a human colony in Mars and shuttles can be made to Mars and back on solar powered space vehicles. True, we are not there yet, but I believe that discoveries in physics, chemistry and mathematics are not yet entirely exhausted.
We must remember that there was a time in history that it was impossible to claim that the world went round the sun. You would be considered a heretic then if you dared to say that the world was flat, not round.
