Single strands of hair strung randomly around a grid? This cannot possibly be an effective approach. But there's an even easier way to prove it's a hoax -- human hair is not an electrical conductor, and doesn't produce electricity under sunlight. (This takes about fifteen seconds to test for yourself with a multimeter.)
