Lagrange Point

Our oceans and waterways are our largest carbon sinks and they're overflowing with CO2. Too much CO2 in our waterways can cause tremendous local damage, but there may be ways to clean that up. Using a cyclic process without messy membranes you can get water to release the CO2 captured inside. Extracting excess CO2 from oceans could be possible with only some clever chemistry cells with no waste byproducts. Now that you've got CO2 out of the ocean, what are you going to do with it? Make it work for you. Carbon sequestration can be more useful than just pumping it into the ground. With the right techniques you can use excess CO2 to improve construction materials.  Seoni Kim, Michael Nitzsche, Simon B Rufer, Jack R. Lake, Kripa Kiran Varanasi, T.
