Today I read about sending sound through light (in this case a laser beam) and on the other end they were using a small solar panel one would remove from a garden light or something similar. The solar panel was connected to an input jack on a receiver. So I began to wonder, although I haven't yet tried it... what would happen if I hooked up a solar panel to a receiver outside? Could I possibly pick up stray communications floating around in the sunlight? Has anyone here tried that and if so, what were the results?
