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.
