If I move into very hypothetical areas, I could possibly see a move to
have residential areas supplied at 50v or less, under the elfen safety
banner. There would also be an advantage to choosing a lower frequency,
which would reduce transmission losses (around 12% at lower voltages).
The flicker effect of a lower frequency could be overcome by mandating
only high frequency fluorescents or all LED lighting.


That's going to be a big cable to my 3kW kettle and heater ;-)

There's something to be said for higher voltage = lower current and a
lower risk of fires.

25mm2 meter cables are bad enough - 125mm2 ??
