The other day, I was reading an invention that captures CO2 from air directly and collecting it. Then, they would sell it to Coca-Cola to make soft-drinks. It is simple but not yet economical as they pointed out, and this is their challenge.
Today, I saw another article about scientists looking to “enhance” plants to capture more carbon by making its roots deeper in the soil and keeping the CO2 in the soil for hundreds of years.
By joining these two ideas, it will give you a new solution, which is putting CO2 in the soil to make plants grow bigger. We all know that CO2 is the food of plants that makes them grow. Therefore, putting CO2 in the soil is good. Of course, you cannot directly put CO2 to the soil without mixing it with something. Water is a good candidate. By mixing CO2 to water produces carbonated water, just like soft-drinks (It’s not advisable to use consumer soft-drinks of course).
According to University of Colorado Boulder, that plants given carbonated water makes it grow taller by 170%.
