Initially puzzled by what 'energy' creates the crop circles and being sceptical of hoaxers claims, I decided to visit some crop circles in person to see if I could detect any anomalies. Back in 1990 I had discovered that crop circle sites could possibly exhibit some kind of effect on electronic circuits, and have been investigating this phenomenon ever since.
My earliest research involved experiments based around a home-made gizmo which seemed to indicate a difference between 'genuine' crop circles and man-made or naturally flattened crop. It was almost as if what was making the crop circles was draining the localised area of all electromagnetic energy, or 'earthing' the area. This was indicated by a complete lack of electrical energy being detected on the gizmo.
