"Tesla's transformer in full activity produced twelve million volts and a frequency of one hundred thousand oscillations per second. The flame like discharges measured sixty-five feet across. From the outside antenna these sparks could be seen from a distance of ten miles. The high frequencies and high voltage electricity does not pose a danger to human health because there is no penetration of skin and deep tissue and no interference with the electrical activity of the heart and brain."
