Nikola Tesla (pronounced Teshlah) [invented] the Tesla induction motor which made alternating current practical, and the Tesla transformer which steps up oscillating currents to high potentials. Last week was Dr. Tesla's 75th birthday. To Nikola Tesla, all the world's a power house. For 40 years he has been reasoning, calculating and arguing that the earth has a definite electrical resonance. All that men need do to have unlimited power at their command, and that power without the necessity of transmission wires, would be to generate electricity in tune with the earth's. Only possible drawbacks would be the vast expense of installation ... and anyone could tap the current. There could be no financial control of electricity. In Colorado in 1899, Tesla built a huge induction coil by which he generated and, he says, sent out wireless waves the same year Marconi established wireless communication. Tesla claims priority, because he conceived his system six years earlier, in 1893. The theoretical path of Tesla's waves were through the earth, not through the air as Hertzian waves go. [Tesla has commented] I think that nothing can be more important than interplanetary communication. It will certainly come some day, and the certitude that there are other human beings in the universe, working, suffering, struggling, like ourselves, will produce a magic effect on mankind and will form the foundation of a universal brotherhood that will last as long as humanity itself." Dr. Tesla migrated to the U. S. in 1884 to work for Thomas Alva Edison, whom he soon quit. His naturalization papers he keeps in a safety box, his scientific medals and degrees in old trunks and cupboards.
