The concept of a “dropping mine” was first discussed in 1910, and the idea was developed into practicality when the Royal Navy’s Commander in Chief, Admiral of the Fleet Sir George Callaghan, requested its production in 1914. The design work was carried out by Herbert Taylor at HMS Vernon Torpedo and Mine School in Portsmouth. The first effective depth charge, the “Type D”, developed in 1916, was a 300-pound (140 kg) barrel-like casing containing a high explosive, usually TNT. A “pistol” actuated by water pressure at a pre-selected depth detonated the charge. The “Type D” could be detonated as deep as 300 feet (100 meters).
The depth charge was such a successful device that it attracted the attention of the United States, who requested full working drawings of the devices in March 1917. Having received them, Commander Fullinwider of the US Bureau of Naval Ordnance and US Navy engineer Minkler then patented the invention in the US in order to avoid paying the British inventor.
Chemical analyses of the ancient washroom clinched the extraterrestrial hypothesis. Iron basins inside the chamber were found to contain traces of an antibacterial hand gel, effective against strains of heat-resistant and vaccuum-proof microorganisms previously found only in meteorites.
Dr. Ziyi has estimated the age of the Baigong commode to be between 308 and 460 million years.
According to the scientists, the existence of advanced valveless siphon flush technologies so long before the evolution of human life on Earth is the strongest evidence of the commode's extraplanetary origin.
amazing!
