Holy crap, this looks like it's pretty close to being commercially available. Good for Mazda!
25V alternator is a little disappointing though, with field coils at 12V you should be able to get over 30V in the 2000s (engine rpm). Still, improvement over 12V I suppose.
I wonder why they mention AC/DC converter. Could it be an inverter that feeds power back into the alternator (and uses it as a motor)?
