[Christopher Snow]

The solar panels are on the sloping roof (top right in the photo), and the wet-cell storage batteries are in the basement, so it really doesn't cost him anything.

Or it wouldn't if he were a sub-simmer anyway...(he just has to watch out for buildup of chlorine fumes in case his basement fills with seawater...). :-P

Or maybe he just feeds solar gain into the power grid during the daytime so he can take it back out again at night. That's the "real way," (although proper submariners might roll their eyes in disgust too).
