The University of California, San Diego reports that its nanoenginners created micromotors capable of removing carbon dioxide from water and turning it into calcium carbonate. The resulting solid material could be used to make bricks or artificial reefs. Currently the setback is the cost for propulsion of the micromotors.

In their experiments, nanoengineers demonstrated that the micromotors rapidly decarbonated water solutions that were saturated with carbon dioxide. Within five minutes, the micromotors removed 90 percent of the carbon dioxide from a solution of deionized water. The micromotors were just as effective in a sea water solution and removed 88 percent of the carbon dioxide in the same timeframe.
