, Edwin R. Scott, Erich Graichen and others claimed to have invented it independently. In 1957, the National Inventors Council was still issuing lists of needed military inventions that included a death ray. While based in fiction, research into energy-based weapons inspired by past speculation has contributed to real-life weapons in use by modern militaries sometimes called a sort of "death ray", such as the

Tesla proposed that a nation could "destroy anything approaching within 200 miles... ndwill provide a wall of power" in order to "make any country, large or small, impregnable against armies, airplanes, and other means for attack". He claimed to have worked on the project since about 1900, and said that it drew power from the ionosphere, which he called "an invisible ball of energy surrounding Earth". He said that he had done this with the help of a 50-foot tesla coil. Antonio Longoria in 1934 claimed to have a death ray that could kill pigeons from four miles away and could kill a mouse enclosed in a "thick walled metal chamber". During
