First problem seems to be it's deafening.

Looks like a DELCO spark plug that's been on the market for a decade or so.

Would adding these generators to the wheel wells be beneficial?




And what is an initial good design for the rear of the car?

the benefit would come from the all-body sensor package that would feed real-time data to the CPU, to calculate generator participation from the terra-byte software package necessary to control and modulate operations. The actual generators would b the easy part. And the entire surface of the vehicle would be involved, as we're in subsonic flow where a change in one location translates to a change everywhere else.

It would have to 'travel', fore and aft, around on the body, as the apparent wind spectra could be constantly changing orientation.

wickerbills need to move from their optimal location?

So wickerbills have to cover the whole envelope? Like dimples?

There wouldn't be any optimal location. That could vary by the mile, depending on weather.
You could do something for zero yaw, but it would be defeated as soon as the wind came up or changed direction, or the car changed direction.

It's been quiet on the ionic thruster front, but here's this:

Designing A Self Propelling Ionic Thrust Wing

Even if it's not enough thrust for a flying wing, surely a Coanda nozzle (similar to Jetoptera's design) grafted onto the aft of an Aptera would be possible.
