The term Radiant Energy is often misused, and has different meaning in different circles of electrical science. The modern term describes radiant energy as the energy carried in electromagnetic waves, across the entire electromagnetic spectrum, including light. It is most often used in the fields of radiometry, solar energy, heating, lighting, and communications. While this description is accurate, the material on our website is more concerned with the 'longitudinal' electric waves discovered by Nikola Tesla, which were the basis of his famous 'Wardenclyffe' experiment. The concept was later explored by T. Henry Moray and others, as a source of electric power for the masses that is not subject to the limitations (or the providers) of conventional 'transverse' electromagnetic power.
