It’s quite shit already

Wild vs domesticated

And somehow it will run on thin air

Here in Italy most houses used to have contacts allowing max 3kW, but nowadays it’s more common to have 4.5kW (with smart utility meters which allow 30% over current for 3 hours).
Still have to be careful if you’re running a washing machine or something like that, but it’s doable.

Of course old houses may have insufficiently-sized wires, and that’s another can of worms.
