The stability and maneuverability of these things requires that they be
controllable rapidly, which can be done with an electric motor. It would
be interesting to see an analysis of putting a motor/generator on the
thing, with some batteries for load balancing (is that the right term?),
Zero auto rotation capacity with that design.. you likely notice his panic
when he climbed to about 20 ft altitude for a moment...
Propeller blade tip turbulence losses on that design have to account for
gigantic energy loss. The inclusion of a simple duct around each propeller

Yes, computer control is what makes these things

There are some quadcopter drones which have computer control of

Possibly, but even today's electric aircraft carry two people for an hour.
This one carries one for 10 minutes. However, the cost is WAY less than the
commercial aircraft. I'm more interested in an electric Cri-Cri myself . . .
