Gas chamber Gas chamber A gas chamber is an apparatus for killing humans or other animals with gas, consisting of a sealed chamber into which a poisonous or asphyxiant gas is introduced. The most commonly used poisonous agent is hydrogen cyanide; carbon dioxide and carbon monoxide have also been used. Gas chambers were used as a method of execution for condemned prisoners in the United States beginning in the 1920s and continue to be a legal execution method in three states. During the Holocaust, large-scale gas chambers designed for mass killing were used by Nazi Germany as part of their genocide program.
John Deere Gator John Deere Gator Gators are used mainly on farms and sometimes in the military, but most people refer to them as farmers' vehicles. They can be ordered with specific off-road features. In 1992, the vehicle replaced the three- or five-wheel John Deere AMTs, introduced in 1987. The Gator vehicles use small but powerful 341 cc (0.341 L) four-stroke engines found in lawn mowers, or an optional diesel engine that is also found in some Deere mowers and utility tractors. They use a continuously variable transmission employing a belt and a conical pulley system. Thus, they require no clutch or gear
