Rust
Rust is an iron oxide, a usually reddish-brown oxide formed by the reaction of iron and oxygen in the catalytic presence of water or air moisture. Rust consists of hydrous iron(III) oxides (Fe2O3·nH2O) and iron(III) oxide-hydroxide (FeO(OH), Fe(OH)3), and is typically associated with the corrosion of refined iron. Given sufficient time, any iron mass, in the presence of water and oxygen, could eventually convert entirely to rust. Surface rust is commonly flaky and friable, and provides no passivational protection to the underlying iron, unlike the formation of patina on copper surfaces. ''Rusting'' is the common term for corrosion of elemental iron and its alloys such as steel. Many other metals undergo similar corrosion, but the resulting oxides are not commonly called "rust". Several forms of rust are distinguishable both visually and by spectroscopy, and form under different circumstances. Other forms of rust include the result of reactions between iron and chloride ...

Thunderbolt Siren
The Thunderbolt is a discontinued mechanical outdoor warning siren made by Federal Signal Corporation. It has a very recognizable design, being a unidirectional siren with a large yellow (or other color based on buyer's choice) exponential horn. History The Thunderbolt siren was developed between 1949 and 1952. It was the first "supercharged" siren, which uses a supercharger to force air into the rotor, greatly increasing the siren's volume. In the 1980s, when civil defense fell into disuse, thunderbolts across the United States were repurposed for nuclear and storm warning siren systems. During the Gulf War, Federal sent a number of modified Thunderbolt 1003s to Kuwait to warn its citizens of an air raid. These were the system 7000 series and were only found in Kuwait. Later, Kuwait's sirens were all replaced with Federal Signal Modulators. One system 7000 is on display next to a Federal Signal Modulator at the Kuwait General Administration of Civil Defense. in Kuwait City, Kuw ...
