For sure, Steven - and 6 volts DC is an engineering challenge as well.
As I understand it, when VW abandoned 6v in the mid-1960s, they almost
went with a 24v system instead of 12v. If they had done this, they
would have saved much production cost on copper.
- In its Prius gas-electric hybrid automobile, Toyota uses 200vDC.
Now we're talking some real QRO-mobile.
