In the article A dash of lime — a new twist that may cut CO2 levels back to pre-industrial levels they go into the details of removing CO2 from the air by adding lime to seawater. “Adding lime to seawater increases alkalinity, boosting seawater’s ability to absorb CO2 from air and reducing the tendency to release it back again. … The process of making lime generates CO2, but adding the lime to seawater absorbs almost twice as much CO2. The overall process is therefore ‘carbon negative’. ” There is a nice Open Source project Cquestrate.
So we have a problem of our own creation, a problem from introducing too much of one chemical into the environment. The solution might be to pour a different chemical into the sea to fix the problem. It could also be completely misguided.
I told a friend of mine, who is a chemist working with catalysts to produce new compounds, about the rare earth elements being exhausted by 2017. (See previous article) She asked me what the problem would be in creating new elements from other elements. She’s teaching me a lot about Chemistry, so I thought I’d look up her idea and examine it.
The process of changing one element into another is Transmutation, which comes from alchemy. It is actually possible, which we know from Nuclear Transmutation or Nucleosynthesis. From what I understand this is easier with radioactive elements, although you can correct me if I’m wrong.
