The electromagnetic signals picked up by a Naystar receiver are surprisingly wispy and tenuous. Their energy density is roughly equivalent to the illumination from the brake light of a Lincoln Town Car seen by another driver 1,500 miles away. Stand on the observation deck of the Chicago Sears Tower, looking toward the western sky, and your face will be bathed by a comparable amount of energy from a 15-watt Christmas tree bulb clipped to the Nativity scene in San Francisco on the Pacific Coast.
