Guest guest Posted March 30, 2006 Report Share Posted March 30, 2006 Hi , solar panels charge a battery and it holds a charge that lasts thought the night. Think of the adding machines that have no batteries. They even work with overhead lights indoors. Think of those lights that folks have around their garden that shine all night, because they were charged during the day. You generally aren't wearing the implant 24 hours a day anyway. Besides, when it's night time here, it's daytime somewhere else, right? The original How would you hear at night...? ;-) NZ Quote Link to comment Share on other sites More sharing options...
