This week, the Energy Department's digital team has been focusing on the rivalry between two of history's most important energy-related engineers: Thomas Edison and Nikola Tesla. Edison and Tesla's developments in electric power generation and distribution made possible many later breakthroughs. This 1951 photo shows a simple string of four 100-watt light bulbs powered by the first useful electricity ever produced by nuclear power, generated on December 20, 1951, by Argonne's Experimental Breeder Reactor 1. | Photo courtesy of Argonne National Laboratory.
