• Resumen

  • The article profiles inventor and engineer Nikola Tesla, the creator of the alternating-current system. Throughout his career, Tesla strove to find the perfect principle on which to base a revolutionary invention. Having identified a grand concept, he was willing to patent and demonstrate it, but he often left it to others to carry out the down-and-dirty work of engineering a moneymaking product. Sadly, as his career progressed, the famous inventor found it increasingly difficult to convince prospective backers to help with the messy process of commercialization. Tesla mustered the energy in March 1886 to file a patent application for a thermomagnetic motor--a novel device powered by heating and cooling magnets. By September 1887 Tesla discovered that he could produce a rotating magnetic field by feeding two separate alternating currents into pairs of coils set on opposite sides of the stator. Searching for a way to create an arc light for use on alternating-current networks, Tesla now found a new fundamental ideal on which to focus: high-frequency electrical phenomena. The inventor investigated this grand concept for the next 15 years. INSET: Overview/Nikola Tesla.
