Hello, I am just curious on the physics of how electrical energy is
transmitted wirelessly.  Is it like the propagation of
electromagnetic radiation like radio transmission or is it not waves
at all?  Are there any sites out there that would be helpful towards
this inquiry?  It would be great to figure out how Tesla coils do
what they do, thanks for the help!

Hi Langer,

Two coils very close to each other can couple capacitively. Tesla showed in experiments that energy can be conducted through a partially evacuated tube (~150 mmHg) and speculated that with antennas 10-15 miles high, transmission by conduction would be possible. All other transmission to date is by electromagnetic radiation (radio waves). There are, however, thousands of pages of speculation and foolishness on the internet. Much of it by those who reject all physics of the last hundred years and insist on the existence of the "lumeniferous aether", longitudinal wave propagation, inter dimensional phasing, UFOs, gov't conspiracies, Bigfoot, and Elvis' return. Although there has been much often vocal opinion to the contrary, Fact is no one has yet been able to demonstrate in a reproducible manner any other forms of transmission, or any observed phenomena that can't be adequately explained by standard EM theory. To quote an anonymous Native American of the last century "Much wind. Much dust. No rain."
