That's really cool.  Only 300ft needed to takeoff and land is amazing.

I wonder if using the engine to power a generator is more efficient than using it to directly power a propeller.  Certainly augmenting this with some batteries makes it even more efficient.

I'm also guessing that using the props to provide some lift airflow does require a tradeoff in the form of slightly reduced speed, but I could be wrong about that.

Anyway, this is a really cool concept.

From the website:

The turbogenerator is sized for cruise, the battery boosts power for takeoff and landing. This way the turbogenerator can be small and always operates at its most efficient operating point. Operators can charge the battery in flight via the turbogenerator, or charge them on the ground.

A lot of the blown-wing is as a result of directing airflow at the large flaps. Once flaps are stowed its ultra efficient.

Can land and takeoff at 35 knots.

Incredible STOL capability!
