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."
