The challege of “Solar Impulse”:http://www.solarimpulse.com/en/hbsia/index.php?idContent=44&idIndex=19

To make an airplane take off and fly under its own power, both day and night, entirely propelled by solar energy, and in so doing, take a step nearer to perpetual flight, without fuel or pollution, is an unachievable objective, unless current technological limits can be pushed back. Never before has an aircraft been constructed with such large dimensions and yet remained so light, and never before has a system of propulsion been perfected to such a level of efficiency. The greatest hurdle before the round-the-world flight will be not only to make it fly at night, but also controlling such an innovative airplane in the air.

The history of exploration tells us that major discoveries have never been easy, nor won in advance. In its search for the extremes, both technological and symbolic, “Solar Impulse”:http://www.solarimpulse.com/en/hbsia/index.php?idContent=44&idIndex=19 has set out on the arduous and high-risk path that all pioneers tread. A path that will allow the exploitation of the immense potential of renewable energies. A path that will lead to the changes needed for better use of energy resources and greater respect for the environment. Will the solar aircraft be able to defy the long nights and fly without any fuel? Will the adventure be possible? Will the dream of perpetual flight become reality?

This is a truly inspiring project which I am sure will open new doors for greener ways of travel and thinking. I wish Bertrand Piccard, André Borschberg and their team the best of luck and look forward to supporting this project by posting events as they unfold.
