When Nikola Tesla applied acoustic principles in his experiments, the results were outstanding. It led to many of his inventions including the Tesla Coil, which forms the basis for the circuits used in televisions and computers, and to wireless transmission, which became radio. It was these same principles of resonance, vibration, frequency, harmonics, and tuning that he was applying to tap into and harness the natural energy of the earth, which he called the ‘aether’, or the ‘wheelwork of nature’. He believed it formed the underlying structure of the universe, flowing through the space between the stars and within the tiny particles that make up matter.
At the turn of the last century Tesla discovered the earth has a resonant frequency and that multiples of this frequency, known as ‘harmonics’ or ‘standing waves’ could be created between the earth and the upper atmosphere by lightning. This led him to use one of his inventions – a large Tesla coil – as an instrument to generate standing waves so that at the right frequency the earth would respond to the transmitter’s vibrations.
