I wonder how research is doing to concentrate CO2 from the PPM amounts we have "in regular air" There are at least two low-hanging fruits that make it "easier"

There are at least two low-hanging fruits that make it "easier": CO2 is heavier than other important gases and mildly polar.
- magicalhippo 6y agoPlant lots of trees or similar, then burn them for electricity and capture the CO2 from the smoke. Compared to a lot of the other proposals out there it almost sounds plausible.

- marcusverus 6y agoWhy not just do a partial burn and reduce the remainder to charcoal? It would be much cheaper, require no chemicals, and the end product is pure carbon, which would be easier to store. You could literally dump it in a pile and deal with it later.
- idiotsecant 6y agoMaking charcoal is not energy-positive and still only results in about 50% carbon capture, best case scenario. Burning it in a biomass plant with good carbon capture does better and displaces carbon-emitting generation processes at the same time. As an added bonus biomass plants are excellent 'baseload' type plants, a feature that wind, solar, etc are missing without expensive storage and complex management schemes.
