Use of Wind Power in Antiquity?

History Channel recently featured Dr. Maureen Clemmons who theorized that perhaps the ancient egyptians used kites to lift and transport stones and monuments in their construction of pyramids and obelisks. I find her theory intriguing since it implies that the symbols like the ankh and the scepter of horus could have been used to control a kite line and used as pick-axe respectively. If her theory is right, it interesting how hieroglyphic symbols perhaps associated with common tools in the ancient became associated with religious beliefs.
