If your lab is haunted, you can call an engineer instead of a psychic. Even celebrity medium James Van Praagh seems to think so. Though he claims also to be ”clairsentient,” able to intuit messages from ”the beyond,” Van Praagh says that even those not so gifted can sense spiritual entities with the help of a little technology. His new best seller, Ghosts Among Us: Uncovering the Truth About the Other Side (HarperCollins, 2008), offers a list of electromagnetic field readers, Geiger counters, digital video and audio recorders, thermometers, infrared thermal scanners, and audio amplifiers. ”These devices,” he says, ”pick up temperature drops and spikes in electromagnetic charges that often signify the presence of ghosts.” Talk about spectral efficiency!
