Yes the inability to go to the nearest WallyWorld and buy a 240V 4kW
cooker/microwave/whatever is a big problem. European appliance could be
got, but I'd worry about anything with a motor (50 Hz), clock (do their
electronic clocks operate off the line frequency like some in the US?),
microwaves (don't they use frequency-dependent constant voltage
transformers?).


I don't know if microwave ovens still use ferroresonant transformer
supplies. I'd heard that they'd moved to switchers but have not
worked on any with same. It would make sense: good transformer iron
& copper ain't cheap... and a switcher would also save shipping weight.

And yes, the clock would run fast.
