    Two vids about an electric airplane from our own Bjorn Nyland. Very cool look at the future. Thanks Bjorn.

    Just 21 kWh battery, and after a 15 min flight the plane has only consumed 15% or around 3 kWh. Incredible.

    This is not new... the Pipistrel has been around for awhile... I used to work for Siemens and this was a long term project for them...

    New to him... yes..

    Not to the aviation world...

    It's the Pipistrel Alpha Electro. I'd seen/read about it before.

    Pretty efficient given the cruising speed.

    It shows both how much planes need a battery density increase, and how much they'd benefit from one.
    Consider what would happen to this plane with double the density: 2 1/2 hour flight at light load (remember that it has a half hour reserve), or, more likely, over an hour range if built to support a bit more passenger load, which would make it much more flexible as a trainer.

    There's a racing group that wants to begin an electric race series in 2020.

    There are of course various companies working on other electric plane projects.

    All about the batteries.

    A fully electric 300+mph racing plane. note: counter rotating props.

    That was an amazing video.

    I was wondering if it makes sense to have two motors , one for each of those counter rotating props, or just have one big motor and have a gear that counter rotates one of the props.

    I am sure the team would have weighed in that and choose two motors.

    If you watch the video, they explain how dual props work and how they are powered and why.

    I am not questioning the need to have dual props.

    Go back and read my post again.

    better control, less gears, perhaps
    could just be simpler
    redundancy - one goes bad you got the other.
