It never occurred to me that in an power outage emergency there might be a way to power your home through a fully charged electric car...Till just reading that it's now possible. "Electric vehicles can now power your home for three days...some automakers are now promising anyone with an EV: An enormous home battery on wheels that can reverse the flow of electricity to power the entire home through the main electric panel." - and people have jerry rigged it too, already... as per Washington Post
