The Great Pyramid of Giza is one of the best examples of ancient energy machines. It was a Tesla-like power plant created thousands of years ago. It was a huge ancient structure that was capable of using the Earth’s natural properties in order to create or produce a great amount of energy. This energy is believed to have been used by the ancient Egyptians and other cultures such as the ancient Maya and other cultures around the globe for millennia. This theory, however, has been firmly rejected by mainstream researchers.Did you know? The stone blocks used in the inner parts of the Great Pyramid were made from limestone, which contains small amounts of crystals and metals which are believed to be two important properties that allowed maximum power transmission. Furthermore, the shafts built inside the Great pyramid were made of granite which is a slightly radioactive substance permitting the ionization of the air inside the air shafts of the Great Pyramid; similar characteristics can be found in a conductive insulating cable.
