A compact, chemical-free way to remove carbon dioxide from the air inside deep-sea vehicles and other human habitats is being developed by researchers from the University of Bath in the United Kingdom and Duke University in the United States.

The system uses a column of seawater and Dixon rings—fine wire mesh folded into a ring about 3 mm (about 0.1 inch) in size.

With this “compact gas scrubbing” system, chemicals would no longer be needed, and the time spent underwater could be extended, say the researchers.
