Light Without Heat (Mar. 24, 1893)

Light without heat, the production of which has been the object of much work by scientists, is said to have been at last obtained by Nikola Tesla, a man of independent fortune and brilliant mind and who was for some time associated with Edison. The halls of the Royal Society of London and of the Franklin Institute of Philadelphia have been illuminated by means of the light radiated from bare copper wires in the open air carrying the so-called Tesla currents. The wires were not hot, but they radiated from their surface light and sent from one to another bands and streamers of the mysterious light which we see in the aurora borealis. Mr. Tesla is an Austrian, and is the son of a priest of the Greek church. He is about 30 years old and has devoted much time to the study of alternating currents of electricity. His recent lectures in St. Louis attracted crowds to hear him tell of the wonderful things he expects to accomplish.
