That was very long but very very interesting. Full of facts.

Thanks for that, Bill.

Pretty well all of that info is available[1] over the internet
(wikipedia is a good starting point for those interested in such
technicalities[1]). Indeed, until I checked out 'my facts', I hadn't
quite realised just how serious an issue there was in drawing power via
the commutator/brush gear - at least half of each of those old Edison
100v dynamos you see archive pictures of are just to accommodate the
several banks of commutators/brush sets required to draw their designed
amperage.

[1] Blimey! I managed to spell "technicalities" correctly first go, yet
still managed to misspell "available". :-( :-)
