David,

You're not wrong.  In fact the very first major lighting installations was
done exactly this way.

William Armstrong built 'Cragside' in 1865/1866 which was powered by lakes
in the grounds - he used hydraulic power and hydroelectric power.  At first
he lit the gallery with arc lamps, but in 1880 he changed to incandescent
lamps to light the whole house. Armstrong was pals with Joseph Swan the
true inventor of the incandescent lamp.

ISTR that the house had about 85 lamps but the hydroelectric generator
could only power about 60 at any one time.  All the wiring went back to a
room where a butler switched circuits on and off as instructed via speaking
tubes (voice pipes) - the whole house was networked for comms as well.  I
suppose this was the first Node 0 for home automation.

Just when you think what you're doing is 'cutting edge' you find it's all
been done before and a long time ago at that !!!

Regards


Simon

I wouldn't be surprised if the first electric light installations had
all the power switches in the pantry because it would be quite clearly
the butler's job to turn them all on/off :-)
