A friend was without power for a few days. His wife has a beautifully decorated yard with a whole bunch of those small lights that rim the yard and come on at night to light up the place. During the day, the tiny solar panels on the lights charge up the batteries in order for the lights to run all night. During the power outage, he went out in the evening, snapped the lights off of their bases, and placed them all over his home, lighting up the house (when everyone else was in the dark) just like they had never lost power. In the morning he replaced them so they could re charge then in the evening, he went out and got them again for use in the house. Good idea!
