Did you know that there are thirteen different versions of the electric socket? They are used in four different combinations of voltage and hertz. There are six billion people across two-hundred and fourteen countries that live within this mash of plugs and power levels. Our work is not complete.













I would be surprised if the entire world’s population live within reach of an electric socket, although a liberal interpretation of your post would conclude that simply living within a boundry covered by a wire carrying electricity would qualify, even though that boundry could be far from reach.
So, friends of Frank, how *do* you work this thing?
