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?), sorta

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 would increase

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 . . . https://www.youtube.com/watch?v=rkEHIv1o7u8
