A 42V DC? shock could be pretty bad. The new Toyota Prius uses 273V for
the
traction motor, but that is very local to the hybrid system. Maybe a low
voltage higher frequency AC system might be a solution as someone
suggested
earlier in the thread. Conversion efficiencies are pretty good these
days
with more advanced controllers. Then individual components could step up
the
voltage and convert to higher DC voltages as needed.


I've worked on a lot of 48 Volt systems and it is more like an unpleasant
tingle than a bad shock.

Higher voltage means thinner wiring, cutting weight.

I meant if things got wet, it could be quite a tingle. Considering the
highly litigous public in this country, I can see the lawsuits if poeple got
even slightly "hurt". Agree about the copper savings. I grew up with 240VAC
power and that is something you don't fool around with. I have also had
shocks from the flyback transformer in TVs and ignition systems in cars, but
those are likely to get you physically hurt (uncontrolled muscle reaction)
than the shock itself.
