Very cool article! It will certainly be interesting to see how we get around these hurdles. The most interesting one to me was definitely the lack of being able to electrically ground anything, we will definitely have to design newer electrical motors etc to get around that!
It wouldn't really impact devices, it would impact buildings.
(for household service, ground and neutral are bonded at the service panel, grounding is a safety issue, not something electrical devices depend on to function)
