Dear Dr. Tulaikova,

Where was the method tested?

(I mean the spraying of alkaline substances into clouds...)

Best regards!

There is only a model now, but I will be very glad for your approval and for further joint experiments with clouds. Please read the model and core calculations, I add in today as a full text to my monograph. And what do you think about real difficulties?

Well, the subjects is of interest, but I have to check out if there are available programs that support the performing of the experiments.

Actually, up to the present, the main method to reduce CO2 was the... planting of trees = increase of forested areas (in many countries there are these kinds of activities - related to the Kyoto Protocol -, most of them being endorsed by GEF/World Bank).

This model (with the spraying) seems to be a more technical one - in the field of environmental engineering.

One of the difficulties will probably be represented by the fact that most of the decision-makers will not accept a large-scale application of the method. At least not without a prior small-scale testing with (only) positive results.

Zsolt Török,

Please read the bottom of the full text in my book, where I add photos of the plants after purified rains.

Dear Tamara, I can see one limitation for your method. Right now, we should burn large amount of organic fuel to spread the chemicals in clouds. More, even distributed in small water droplets, KOH can be an ice condensation center, and will change significantly local and global weather. Maybe, it is more practicle to dissolve KOH in Ocean waters? In long-term model, all CO2 from air will react with such water.

Dear Alex, this method can be used in Russia only in the summer, of course, we have snow in the winter. Many ions remain in the plants , please see the full text in one of my books with photographs of these plants. These issues still need to study and simulate. In the surface waters of the ocean is held up more CO2 than in air above, because ocean water has pH=8.3, so the nature use the same method.

You may provide some experimental data by following physical and chemical processes in clouds (and precipitations) associated to Saharan dust transport. Very often, rains under the influence of Saharan dust show a pH much larger than the expected 5.8. In fcat, in additional to "acid rains" in Italy we are sometime also experiencing "alkaline rains"

Dear Dr. Ivo Allegrini, thanks, I will be very grateful for any data or reference for any real measuriments.

I calculated the speed of cloud re- condensation for steam to the droplet of alkaline solution, these graphics presented in our work. Also it is obviously from physical view, that hygroscopic alkaline droplets well collects water around, but we need only get the desired pH according to the parameters of cloud by calculations. But I fear anything else, and I hope for your advice also.

Can You specify the admixtures or processes in atmosphere, which can prevent for realization of the strong CO2 absorption for alkaline droplets?
