  • Patent number: 9581021
    Abstract: A system for extraction of volatiles from bodies in a vacuum. The volatile containing solid may be subsurface heated with microwave or RF energy subliming volatiles that are captured with a containment structure that directs the flow of the volatile through a cold trap for collecting and condensing the volatile. In one variation, a sample, or an entire body may be enveloped in a sealed container for extraction of volatiles that are then collected and condensed. In a further variation, a planetary surface area is covered and the perimeter sealed at the surface. The area is then heated from above to release volatiles that are then collected and condensed. To heat layers below the surface that contain high concentrations of volatiles, a hollow auger can gain access to the subsurface volatile and microwave or RF energy can be delivered down the hollow auger with a coax cable and vapor can escape through the hollow auger to a capture apparatus.
