The big (special order) Peugot and BMW models use them now - called Internal
Starter Generator - runs on 42 Volt (!) - creates a very bad magnet field if
the cables are not close together (touching) and need a special power controll
(shut off controller) due accident problems - creates a light bow if the cable
brokes by an accident which brings every kind of gas fume (or fuel) to an
agressive burn/fire reaction...
See ya
