… observed in 1835, found its first application by 1852 as a lightning protector for telegraph lines. Under stress of a high voltage lightning strike, the coherer would short to ground, thus … thus decohering the chips after each received impulse from lightning strikes. It is now believed by Dr. James Corum …
… Tesla was elated. His next step was to actually produce lightning. As a Tesla biographer records: “Tesla's eyes … popped out of his head as he saw full-fledged bolts of lightning darting into the air, accompanied by a barrage of tremendous crashes of thunder. Those lightning bolts were now half again the length of the …
