Nikola Tesla and several other scientists were into electric universe and catastrophism.

Longitudinal waves p waves are where the wave moves along with the medium.

Transverse wave/s wave is when the wave moving perpendicular to the medium. When you are using energy that's a transverse wave.

Megalithic sites converted p wave coming through the earth into s wave. The longitudinal waves are coming from certain angles(other megalithic sites)

Is it really coincidence that many sites are aligned? Giza, Machu Picchu, nazca, easter, Angkor, Mohenjo-Daro, Persepolis and 5 other sites are in the same line and this was probably the old equator of the earth. North pole was 250km south of Haarp research. There are even more coincidences such as some sites being at a Golden ratio with another(145 degree or 111.1 deg).

I need to write a book about it but in short there is a correlation with Earth's seismic properties and the ancient sites. Google search longitudinal and transverse wave shadow zone inner earth. There are shadow zone between 111 to 150 degrees.

How does a megalithic sites convert wave types? Well. It can. I think there are even plastic toys that demonstrate that transverse wave flowing horizontally will push a longitudinal wave vertically.

Now, read Judy wood where did the towers go. 9/11 was an energy weapon event.

Haarp isn't what you think. Yes Wallace Thornhill was right about ionosphere and earthquake but it's not Haarp firing energy weapon to the ionosphere. You are looking to far away when the answers are under your nose, sometimes beneath your feet. Haarp is a public research center with data. Their job is to analyze the wavetypes inside the earth. Just like Haarp Puerto Rico and exmouth naval radar station. Puerto Rico and Australia are antipodes of each other.

Why would there be a need of converting wave types? Because longitudinal wave can ricochet. Transverse wave usually don't. If a p wave sent from Giza hits ollantaytambo then it can create an echo and also go towards Mohenjo-Daro then later towards richat structure.

Does this mean Nikola Tesla was hundred percent right about the earth actually creating energy? Well that's bit difficult to say. I won't be surprised if the earth can generate a bit, specially if the waves are fired from north to south
