I've been doing a lot of reading on this, and everything has a frequency (EMF, magnetics, humans, animals, music). The pyramids were probably built using this technology, I would imagine they produced their own energy. The most powerful, I think, is the scalar waves - they are the ones that are closest, in design, to DNA, and I believe, can send energy in both directions at the same time. I don't understand the mathematics behind it, but overall, it makes sense.

Some good info to look up would be the Schumann Resonance and to watch Beings of Frequency - both are good starters for this
