IN SEARCH OF NIKOLA TESLA there are electrical effects arising from shock waves in the earth's crust. Earthquakes, volcanoes and the daily movement of fault lines produce mechanical pressure waves which travel around the earth. As they pass through certain rock formations, electromagnetic fields are created which then travel across the earth. So Tesla was perfectly correct; the earth is alive with the electrical movement of storms, weather changes and the movement of its rocky crust. It so happens that most of these signals are of extremely low frequency and are, therefore, called by the name 'ELFs'. Anyone who has heard a marching band in the far distance will realize that the bass notes carry farthest. The same thing applies to electromagnetic radiation and waves of extremely low frequency can travel right around the earth. The ELFs from weather fronts vibrate at around a hundred cycles per second to one cycle every ten seconds, far lower than the millions of cycles per second used in short wave radio broadcasts. The interference signals from Riga were in the high-frequency spectrum but occurred in pulses or bursts of about nine per second. The lower the frequency of a radio wave the longer is its wavelength. When it comes to waves which oscillate at just a few cycles per second, the wavelengths are about the same size as the earth itself. A wave which fits exactly around the earth sets up a powerful resonance. Tesla proposed to pump energy from his magnifying transmitter at just this frequency, called the Schumann resonance. What do ELFS and Schumann resonances have to do with the human brain and mood-changing beams? There is no simple answer but I think that I can attempt a little speculation. Life evolved on earth in the midst of this electrical ebb and flow. It began with complex molecules, then single-celled organisms and finally the profusion of animal and plant life that covers the planet today. Life is a self-regulating electrochemical process which is both sensitive to its outer environment and at the same time able to stabilize internal fluctuations. It is not improbable that living things developed a special sensitivity to external electrical fields wherever there was an advantage to be gained. The simple organisms respond to external fields in the laboratory and 127
