In the 1970's, inventor Edwin Gray developed an electric automobile engine that produced 80 horsepower and recharged its own batteries. It ran on what he called "cold electricity." This amazing technology remained shrouded in mystery until September 2000. This three-part video is the complete technical lecture given by Dr. Lindemann at that time. In it, he explains exactly how Ed Gray's system works, how he produced "cold electricity" and how that relates to Nikola Tesla's earlier discovery of "Radiant Energy". Using 50 slides of articles, patents, photos, and circuit diagrams, Dr. Lindemann documents his research, until the method is fully revealed. Now you can understand one of the most powerful Free Energy methods ever discovered.
