while not the time of The Great Pyramid, the inventions and ideas of Ktesibios and later Heron Alexandrinus... (one conceived the idea of and the latter built the first steam turbine. all in the latter BCs and baby ADs)... ideas and inventions eventually developed and applied in the mid 1700's to fuel a little thing called the Industrial Revolution... and knowing we still use steam to generate power today.... wood... coal... petroleum... nuclear.....
well, you get the idea.
