Just pump air into ponds of algae/kelp or grow Azolla on the surface. Feed it with fertilizer runoff that's otherwise thrown into the rivers, seas, oceans. No need to build expensive solutions to remove CO2 from the atmosphere.
- snaptravisty 7y agothat sounds like an expensive solution. I can't napkin math any of this since I don't know how much CO2 you could extract along with the other engineering and logistical problems: * which areas are suitable * how much energy is required * how much area of land is required. I hesitate to give credibility to any answer that starts with 'just... [do this thing]'. If you have any references I'd be curious to learn more
