Tesla is often seen in pictures where he sits in his laboratory surrounded in lighting bolts that originate from his towering Tesla coils. It was here he noticed that after they were energized, there was a fresh smell called ozone that was created when the ultraviolet light of the electrical streamers merged with the oxygen in the air. This led him to create a portable device to generate ozone on demand. He discovered that it killed viruses and bacteria not only in his laboratory but also on the surface of and inside his own body.
Tesla and many other doctors believed he had successfully found ways to neutralize disease, bacteria and the harmful EMF radiation using frequencies far outside what was used for home power transmission. Tesla’s ‘High Frequency Apparatus” became popular in private clinics where the patient was placed in a round cage and then energized which resulted in a blue corona discharge over the entire patient.
He eventually incorporated the Tesla Ozone Company with the aid of another $200,000 to produce machines for sale to private doctors, public hospitals and eventually the general public. Portable hand held devices became known as the violet ray. Tesla found that he could ozonate olive oil and sold it to doctors to treat a wide variety of skin conditions.
