If the heights of Physics are of interest to you, you will have a grand time here:

An essential ket to this website is the notion that the Lorentz transform, while it made Maxwell's equations usable to a broad base of people, oversimplified things and eliminated components that, had they not been eliminated, would make our present EM theory a very different thing from what it is now.
The present theory does not present a mechanism for a circuit to couple with the Heaviside energy component, only the Poynting energy. This is a great concern as the Heaviside component is orders of magnitude greater than the Poynting energy and, if we could couple a circuit to the Heaviside energy... Well, you can see where that kind of thing would lead.
Anyway, go play; there are many really cool things to read -- a few "Coast to Coast AM" kind of topics, but don't miss the gems in between.
Sorry, but that pot looks cracked. There is no such thing as free energy. Period.
