No technology has been invented that doesn't have costs and tradeoffs. Technology that deacidifies the oceans will have other costs, other externalities that we cannot predict now. Determining how we want to deal with those costs/tradeoffs is a social problem, not a technical problem. Technical know-how can only inform us about the what tradeoffs are available, it can't tell us what we prefer.
- adastra22 2y agoThe ion pumps enabled by the technology we are working on won’t have external effects. They basically just filter out certain small molecules from the ocean into crystal storage.

- adastra22 2y agoCO2 wouldn’t be pulled out of the ocean. You’d have to liquify it from air in a different process. The molecular pumps are used to extract dissolved ions or solutes from sea water and only act as fast as diffusion.
