Aswan (horse) Egyptian," Aswan's maternal great-great grandsire, Sotamm, was a horse whose pedigree traced entirely to the horses purchased by Wilfrid and Lady Anne Blunt from the stud of Ali Pasha Sherif and imported to England. Sotamm was foaled in England and then sold to the Egyptian government by Lady Wentworth of the Crabbet Arabian Stud. In a near-similar manner, Sotamm's grandsire Mesaoud, imported from Egypt by the Blunts, also sold to Russia and stood at the Tersk Stud when it was privately owned by Count Sergei Aleksandrovich Stroganov and his brother-in-law Prince Aleksandr Grigorievich Shcherbatov.

Hydropower policy in the United States of 90% efficiency. More importantly, Francis's mathematical and graphical calculation methods advanced turbine design and engineering and allowed confident design of high efficiency turbines to exactly match a site's flow conditions. In the 1870s and deriving from uses in the mining industry, the high efficiency Pelton wheel impulse turbine was developed to use hydropower under very different flow and pressure conditions. Advances in dam design also progressed, with the completion of Old Aswan Dam being considered a milestone of engineering over nature. At the time of its construction, nothing of such scale had ever been attempted: it also became one
