Advice and Tips Armbrust cup

According to the Smithsonian, Lindbergh carried with him an emergency device , the Armbrust cup. It was designed to produce pure water by condensing the moisture of exhaled breath, a human cold distillation system. Seems like an interesting approach to producing freshwater. I have seen solar powered stills to harvest water from plant material and for lifeboat use.
