Another idea for reducing CO2 in the atmosphere; again, I think, looking fanciful – helps get publicity for researchers’ projects, ao maybe good for grant money, but doubt this will save us all (in fairness, not touted as great cure).

The technology, invented by Kurt Zen House, a PhD candidate at Harvard’s Department of Earth and Planetary Sciences, and co-workers, involves electrochemically removing hydrochloric acid from the ocean, neutralizing it by reaction with silicate rocks and returning it to the sea. By increasing ocean alkalinity, the process would enhance the absorption of atmospheric CO2. Over time, the CO2 would mix throughout the ocean and eventually precipitate as calcium carbonate in ocean sediments.
