I just had a thought that just because it can be bypassed doesn't necessarily rule out the chance to delete the traditional alternator.
A standard alternator has to be built I assume for the worst-case instantaneous electrical load - t'internet says a F150 has a 130amp alternator, that's one of the bigger alt's I guess, but even so that's 4 times less than the peak on this 6kW device.
The thing is, at tickover the revs in an older car will drop down and can even stall if lots of amps are drawn from the alt. (modern cars ECU will ensure revs stay more level).
So the same principle can apply here if the turbogen is properly integrated.
Of course it's less efficient to increase the output of the engine for more exhaust pressure than it is for shaft power but if you look at the full cycle of driving it's a better deal because you now have extra electrical energy longterm.
