Saturnite Atomspheric Emitter

The Saturnite Atomspheric Emitter is a device invented by the Think Tank of the Big Empty. Designed prior to the Great War, it would've been used to emit the toxin known as the Cloud over the atmosphere in China, wiping out whole populations with little danger to American soldiers. Unfortunately, the Think Tank failed to realize that the emitter worked too well, and could pump out enough gas to eventually cover the entire planet.
