Under 5 for H2/O2. From Len Cormier a couple of decades back.

“Sanctuary…sanctuary…THE BELLS!”

The designer is Semimodo-son of Quasimodo…brother of Paramodo.
But stay away from that pervert- Bimodo!

Need new blade design! https://youtu.be/BCGvIqvDE7c Too damn loud! This thing has to be operating way over 110 decibels.

I do however like the Surefly more traditional gas-powered generator system feeding the electric motors as the battery technology is better understood and nailed down. https://youtu.be/elhiaxMiRuY

IMO the way to safety and certification for these new modes of transportation will be battery-based system with a light weight mini turbine powered generator backup / hybrid setup. (I would never buy a pure electric / battery powered auto)

Joby appears to be the system that is ahead in this field: https://youtu.be/gzG5-3NxeO8

I like the overhead wing design, and the specially designed blades put out about 64 decibels during operation. These new systems if they are to be used in the manner as they are being proposed in the urban environment must be relatively quiet, safe and reliable.

I await to see if the mini turbine generator back up hybrid system will be proposed and adapted to lock up the technology for the FAA and the business model.
