Did Nikola Tesla believe that energy/elecrticity could be tapped from the air?
Yes he did. So Tesla was the first scientist to discover cosmic radiation, or “cosmic rays.” Not Victor Hess, like the internet will tell you. Tesla was 15 or 16 years ahead of Hess. He also understood them far better than Hess, and even our scientists today. But to answer your question, Tesla discovered that these cosmic rays shower down on us 24/7, and that they ionize the air, setting free many charges of ions and electrons. He invented and patented an apparatus that captures these charges in a condenser which was made to discharge through the circuit of his motor. He hoped to build a machine on a large scale but we all know he got blackballed by corporate interests. The important thing about Tesla’s invention is that this source of energy is unlimited–coming from our sun and all the stars in the universe, and could be tapped into anywhere on earth, night or day.
Thanks for the question! Hope I helped.
