The U.S. Patent for Invisible Rays

In 1949, the U.S. government issued a patent for a machine claimed to detect invisible energy emanations from physical materials. The device functioned without standard electronics, relying instead on radionics.

Thomas Galen Hieronymus invented this device to measure hypothetical energy fields he believed were emitted by all matter. While mainstream science rejects the existence of these emanations, the patent office still granted legal protection for the invention. It remains a fascinating example of how pseudoscience can occasionally cross into the official bureaucratic record. The machine is often cited today as a landmark curiosity in the history of fringe technology.
