Anyway, random thought.
Random thoughts is probably why I posted the original link.

Euro 2-pin AC power is the same as USA, just the pins are round and the voltage is double.

That grid of prong sockets on the 15 hole power bar could be adapted to work with flat prong North American plugs. The AC feed apparently runs in a diamond pattern under the sockets, so each hole has the four surrounding pins powered by the opposite side of the AC. Plugs cannot be plugged in on an angle, only north-south or east-west.

Flat prong USA style AC plugs are such a poor design, alas, but I expect we are stuck with it until the end of time.
