The solar-powered experimental airplane Solar Impulse 2 made its maiden flight on Monday.

The solar-powered experimental airplane Solar Impulse 2 made its maiden flight on Monday.

The solar-powered aircraft took off at 5:36 AM CET, when the weather around the aerodrome was at its calmest, with pilot Markus Scherdel at the controls. The aircraft flew for two hours and 17 minutes, reaching an altitude of 1,670 m (5,500 ft) and a ground speed of 55.6 km/h (30 kt). According to Solar Impulse, the in-flight data indicates that the aircraft slated to make the first all-solar global circumnavigation flight performed to expectations.

The goal is to use this plane to fly around the world in 2015. Videos of the take off and landing below the fold. The plane gets off the ground very quickly, does not move very fast, and is balanced precariously on a single set of wheels in the center. If you look closely before takeoff, there are two guys literally holding the wings up at each end to balance it. They have to run with the plane for the first few seconds until it gets enough lift to balance on its own. The landing video shows both bicyclists and men racing to meet up with the wings to hold them up once the plane stops.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

 
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

    I guess I don’t get it. If the thing ran on atmospheric CO2, then THAT would be something. Should we be impressed w 30kt from 200 ft of solar panels?

    The thing that this aircraft is really good at is loitering at altitude with no engines, only solar panels and batteries, it charges the batteries during the day as well as providing current to the four motors and just runs off battery power when the sun stops shining, I believe the first aircraft is a two place design that stayed aloft for over 24 hours by getting to a high altitude and slowly losing altitude through the night, that is this aircrafts big trick.
