And magnetic charges aren't?

Tell me, can you make a continuous (i.e. DC) electrostatic charge =
without oscillating components?  Can you make a continuous =
electromagnetic charge without parts oscillating (homopolar aside)?

I thought not :)

No, RFI has nothing to do with it.

All electrostatic generators require charge transfer, e.g. brushes, =
spark gaps, etc.  These act in the same manner as a commutator.

A Wimshurst machine generates DC from a rotor without a commutator.

Ah, but it has brushes.  If it didn't need commutation, it wouldn't need =
a segmented rotor either -- same purpose.

As far as I know, the homopolar generator is the ONLY generator with a =
rotating construction, contiguous rotor and DC output.

It's trivial to make DC from a linear motor (cf. railgun), of course, =
but reality doesn't allow you infinite rails or magnets.

There is **no** commutation (as Jim stated) and no polarity change.  Brushes
do not make commutation.
It generates a DC charge.

Here, I'll make it a little easier for you to look it up.
