water lines. Moreover, electric vehicles like golf carts are used to shuffle people, equipment, merchandise, and supplies around. Trash is emptied via the utilidors as well. Pneumatic tubes suck trash from the parks to a central location for collection. The Digital Animation Control System (DACS) is also housed in the Utilidors. DACS is the “nerve center” that controls the hundreds of Audio-A

2. A Brief of History of Ammonia Synthesis
In ancient times, ammonia was derived from organic material such as manure and urine. During the Middle Ages, alchemists produced a weak solution of ammonia in water by distilling the horns and hoofs of oxen. They called this ammonia solution "spirits of hartshorn." Later, more substantial amounts of ammo
