Christopher Dunn is an engineer and a machinist who has studied the Great Pyramid extensively. Mr. Dunn has concluded that the Great Pyramid was a power plant that generated electromagnetic energy.
The King's Chamber is composed of granite that contains 50% quartz. The King's Chamber has the same resonating frequency as the resonating frequency of the Earth.
The Great Pyramid was a large acoustical device.
As a huge crystal structure, the Great Pyramid converted the Earth's vibration energies to microwave radiation.
This technology may be used to solve present day clean energy needs.
