There's a power plant in the basement

“The New Yorker Hotel was the most advanced hotel in the world technologically when it was built,” says Kinney. It’s 1 million square feet above ground and 200,000 square feet below ground. The Institute of Electrical and Electrical Engineers (IEEE) named the New Yorker Hotel an IEEE Milestone in Electrical Engineering and Computing for having the “largest (DC) generating plant in the United States” when it was built. It was also one of the first cogeneration power plants in the world. There are only a little over one hundred IEEE milestone sites in the world, and the New Yorker Hotel joins the ranks of places like Niagara Falls and Bell Laboratories."

"The power plant was installed in 1929 and had enough capacity to provide electrical power for a city of 35,000 people. As such, the hotel remained completely off the power grid for thirty years. High pressure boilers made 180 pound steam, sending it over to a massive eightl cylinder diesel locomotive steam engine that powered the direct current electric generators. Exhaust steam was used for heating and other activities within the building, providing the cogeneration part of the plant. Down in the basement, you can still see the motors, over 200 of them, and a sixty-foot long switchboard, which Kinney refers to as the “Frankenstein board.”

Even though JP Morgan abandoned Tesla in his time of need. The US Goverment did not. It swooped in and helped him rebuild Wardenclyffe and provided unlimited funding.

The problem:
ELIHU THOMSON and N. TESLA, later also R. A. FESSENDEN, made early use of this arrangement for the purpose of continuously exciting the natural oscillations of a condenser circuit by means of direct current. It is highly improbable that either THOMSON or TESLA succeeded in actually obtaining undamped oscillations of such frequency and energy as come into question for radio-telegraphy. THOMSON'S spark gap (the arc) had solid metallic electrodes in air at atmospheric pressure; with such electrodes, however, and potentials of not much more than 1000 volts, it is hardly possible to obtain undamped oscillations atTESLA made some use of carbon electrodes, which are far more apt to make the production of undamped oscillations feasible; but even if he obtained undamped oscillations, their frequency cannot have been very high, as even his highest discharge frequency gave an audible tone.

The solution:
This problem was first solved by POULSEN.loa He soon showed that the arrangement of Fig. 244 would give undamped oscillations at radio-frequencies and sufficient energy, if modified as follows:
1. The gap (or arc, F, Fig. 244) is placed in hydrogen or a gas containing hydrogen. .
2. The positive electrode of the gap (or arc) is of copper, preferablycooled by circulating water, retaining carbon only for the negative electrode. .
3. A magnetic field is caused to act upon the arc (magnetic blow-out).Furthermore, in order to improve the regularity of the oscillations, which is of great practical importance, we should add another requirement, viz., .
4. One of the electrodes (the carbon) is slowly revolved about its axis.

“This is, essentially, a circuit of very high self-inductance and small resistance. The electromagnetic radiations being reduced to an insignificant quantity, and proper conditions of resonance maintained, the circuit acts like an immense pendulum, storing indefinitely the energy of the primary exciting impulses and impressing upon the earth uniform harmonic oscillations of great intensity.”

So they were acting as charging stations when there were lightning storms

They used on the outer side of the pyramid granite that was less friable than limestone but still conductible.

Below the granite laid limestone which is more conductive than granite, used for inside walls conductivity.

Basalt was used on the floors for heating the feet 🦶 lol

The water systems helped make the stones more conductive because of their porous characteristics.

From: Christopher Dunn. “The Giza Power Plant.”

The King's Chamber's granite beams resonated at a fundamental frequency and the entire structure of the chamber reinforced this frequency by producing dominant frequencies that created an F-sharp chord. Not surprisingly, the F-sharp chord is believed to be in harmony with the Earth.

It was discovered that the floor of the King's Chamber does not sit on solid rock. Not only is the entire granite complex surrounded by massive limestone walls with a space between the granite and the limestone, the floor itself sits on what is characterized as "corrugated" rock (see Figure 38). Acoustical analysis of the floor of the King's Chamber (by Danley) revealed that the flooring blocks are not sitting on solid masonry. There are pockets beneath the floor that indicate that the support for the floor is "corrugated" like an egg carton, with the flooring sitting on nodes. In addition, the walls of the chamber do not sit on the granite floor, but are supported from the outside and sunk five inches below floor level. The entire complex is freestanding from the limestone masonry, has minimal damping of the floor, and is thus free to vibrate at peak efficiency.

“The granite complex inside the Great Pyramid, therefore, is poised ready to convert vibrations from the Earth into electricity. What is lacking is a sufficient amount of energy to drive the beams and activate the piezoelectric properties within them.

They had determined that they needed to tap into the vibrations of the Earth over a larger area inside the pyramid and deliver that energy to the power center—the King's Chamber—thereby substantially increasing the amplitude of the oscillations of the granite.

The Great Pyramid can be seen as a huge musical instrument with each element designed to enhance the performance of the other.
As the Earth's vibration flowed through the Great Pyramid, the resonators converted the vibrational energy to airborne sound.

This sound was then focused into the granite resonating cavity at sufficient amplitude to drive the granite ceiling beams to oscillation. These beams, in turn, compelled the beams above them to resonate in harmonic sympathy. Thus, with the input of sound and the maximization of resonance, the entire granite complex, in effect, became a vibrating mass of energy.”
