Yes, I understand the doubler is a usual method. I was making this point for
amusement purposes. As you guessed, I was using "rest of the world" in an

I'd argue that I would be far happier? clasping my hand around a storage cap
fed via a switched inductor and diode quadrupler than a cap charged directly
via a diode from a transformer powered via a power station. The impedances
are a -lot- higher

Yes, they do seem (even more so) as fearless as some automobile drivers. The
crazy auto driver though will kill lots of other people in pursuance of
their own vain stupidity. The lone electrical experimenters fortunately only
top themselves. This is true Darwinian natural selection at work.
