Edward F. Malkowski is an American writer who coined the phrase ‘Civilisation X’ to describe a prehistoric ‘Greater Mediterranean civilisation’(i)* exemplified by pre-dynastic Egypt. His earlier Before the Pharaohs  was soon followed by Ancient Egypt 39,000 BCE . Although he refers to Atlantis(a), he is somewhat ambivalent regarding its existence [657.284].
However, Malkowski is thoroughly fascinated by the Giza monuments, particularly the Great Pyramid(c), regarding which, he follows the ideas of Edward Kunkel(d) and John Cadman(e), who proposed that the Great Pyramid functioned as a water pump. However, Malkowski believes that such a pump had an additional function, namely, to generate compression waves that in turn would cause the pyramid’s granite beams to vibrate. Then, “with shafts leading to the Great Pyramid’s exterior, the ‘singing’ granite would project its sound into the atmosphere. This, in turn, would create an electrical field in the atmosphere according to physics research.” (f) This gentle electrical field would have been used to generate plant growth in the surrounding land. Why it would be necessary to build such a huge ‘machine’ to promote growth on land that is renowned for its annually renewed fertility with the flooding of the Nile, completely eludes me.
>Nevertheless, the idea that the ancient Egyptians had some degree of electrical knowledge has been put forward from time to time a recent example of which has been proposed by an engineer, Andrew Hall, who offers his evidence for claiming that the ancient Egyptians had used electricity in an illustrated article(j) and a YouTube video (h). However interesting his ideas are, they are still based on speculation and a subjective interpretation of Egyptian hieroglyphs and wall paintings.<
Malkowski’s theory that the pyramids were used to promote agricultural fertility brings to mind the ideas expressed by the American scientist Philip Callahan, who has suggested that the electromagnetic properties of the round towers of Ireland “provide large-scale benefits for agriculture just as the small scale round towers have been demonstrated to be beneficial for potted plants”! However, Callahan’s claims go much further with his belief that “the pyramids, both Egyptian and Central American, were huge antigravity structures for levitating the priests. The pyramid acted like a huge “enlarger-type” condensing lens which concentrated the cosmic energy into the hollow resonant stone tower, which in turn was filled with the IR-paramagnetic, organic breath of chanting priests.” (g)
Malkowski has also written an interesting paper on Ice Age theories, which ends on a note of personal scepticism regarding currently accepted ideas(b).
