Also read in, I believe Motor Trend, Mercedes Benz was also going to use a 42 volt system. And no, this was not dislexia. (24/42)
The higher the voltage, the less currect, therefore smaller wire.
Just think how large cross country wires would have to be if we transmitted 220 volts AC overhead.
5 to 6 feet in diameter still wouldn't cut it.
Ah yes, when Airstream goes to 42 volts DC, then the 6 volt battery believers will have to install 7 of them.
Good luck with that dream, and weight, and space.
