    People who create things like this amaze me. Awesome.

    It's 30 MPH of fragile.....Good luck. Needs calm still air......

    I did get to see this fly at Sun n Fun. Goes good and it was windy the whole week.
    No problem.....

    I had lunch with one of the pilots a few weeks ago. They are really doing some amazing things with this technology.

    From the site. Interesting power saving ideas.

    "During the day, the pilot slowly ascends to a higher altitude in thinner atmosphere to avoid turbulence and cloud formations. Interestingly, the solar generators also convert more energy at altitude. Sun radiation is partly absorbed by Earth´s atmosphere before reaching the ground. The higher Solar Impulse is climbing, the more sun power is available and can be stored in the batteries. In fact, for the highest possible solar power generation, HB-SIA should be in outer space; but that’s a little too far for the time being.
    As the sun begins to set on the horizon, solar power obviously decreases. Once the available solar power is not sufficient to support level flight anymore, the pilot reduces the motors and initiates a gentle descent (about 0,4 m/s) to a low night loitering altitude of 1000-1500m meters. Out of its maximum altitude of 28000ft (8000m), the prototype can glide for 4-5 hours consuming almost no electric energy. When the lowest altitude is reached, usually long after sunset, the motors, now powered by the batteries, are used to maintain a level flight at 25 knots until the morning. As the breathtaking tones of the sun on the horizon start filling the sky with warmth, the aircraft can once again begin its ascent, and the cycle begins."

    awesome...
    They've been flying this for a while now. nice to see them pushing it forward though.
    Now all they need to do is master the act of mid-air refueling...of the pilot.

    While it is "cool" I think a glider could do most of this. Longest recorded flight for a glider is over 15hours and 2500km with no engine. A glider can also fly in normal conditions not these almost unrealistic calm days.

    Kind of hard for a glider to takeoff on its own, and won't make it through the night.


    Drove 4 hours round trip for the chance to look at it this evening and talk to people from the project. It was disappointing that there was very little turnout to see history in the making.

    The technology was amazing. Got to hold a piece of a rib structure. Carbon fiber with a bit of foam. Incredibly light.

    I'm hoping to ride up to see it while it's in St. Louis. The itinerary used to "St. Louis or Nashville."

    When it gets there? :evil


    Cool but, I think it does more to highlights the limitations of solar tech and electric aircraft than anything else.

    Make sure you find the link to the Eventbrite reservation system to get tickets to visit. It's a little tough to find on the website.

    I think we may try to go back up to see the departure for Dallas. They're planning on Friday or Saturday if the weather continues to be favorable.
