Hi David,

Automotive alternators do not have the output voltage determined by
windings but by the drive applied to the rotor windings through the
regulator...up to the physical capacity limits of the hardware used.
Automotive alternators have been used for welding and for powering tools
like electric drill motors for years. If you want to consider a 50 volt
application you can buy a 'replacement' alternator designed for use with
an external regulator and then make your own regulator.

I would not recommend driving very far on just the battery in any
electronically controlled, fuel injected car. The auto industry has
considered a move to 42 volt systems to help with the huge electric load
in these cars. Maybe they can be convinced to go all the way to 48 volts
(really 50).
