Marconi developed long range wireless communications over the course of many years, building larger and larger towers and more powerful transmit stations until they finally collapsed by their own weight. He had miscalculated that radio transmissions had to be long wave high power. At the time it was not known what an electromagnetic wave even was. No one knew. Marconi did not believe radio waves traveled in straight lines. He thought they followed the curvature of the Earth. As it turned out in the end the waves are very short and require only very low power. By contrast ELF (long wave) communications at wavelength of 75 Hz requires one million watts of transmit power. This is what happens sometimes, when people assume something and take it to the extreme. Sound familiar?
