Abstract

A system and method for reducing global warming. The system can include a container having a body portion for retaining a quantity of alkaline metal hydroxide and collecting a precipitate. At least one inlet on the container can be utilized for introducing a volume of air containing CO₂ into the alkaline metal hydroxide, so that the CO₂ in the volume of air can react with the alkaline metal hydroxide to reduce the amount of CO₂ in the volume of air and to form a precipitate in the body portion of the container. At least one outlet on the container can be included for releasing the volume of air having reduced CO₂ content into the atmosphere. A pump can be included for injecting the volume of air containing CO₂ into the alkaline metal hydroxide under pressure.

Claims

1. A system for reducing global warming comprising:

a container having a body portion for retaining a quantity of alkaline metal hydroxide;

at least one inlet on the container for introducing a volume of air containing CO₂ into the alkaline metal hydroxide to allow the CO₂ in the volume of air to react with the alkaline metal hydroxide to reduce the amount of CO₂ in the volume of air and to form a precipitate in the body portion; and

at least one outlet on the container for releasing the volume of air having reduced CO₂ content into the atmosphere.

2. The system of claim 1, further comprising a filter having adsorbing material for filtering the volume of air containing CO₂ prior to introducing the volume of air containing CO₂ into the alkaline metal hydroxide to remove contaminant particles.

3. The system of claim 1, further comprising a pump for injecting the volume of air containing CO₂ into the alkaline metal hydroxide under pressure.

4. The system of claim 1, further comprising a dispersal mechanism for efficiently dispersing the volume of air containing CO₂ throughout the alkaline metal hydroxide.

5. The system of claim 1, further comprising at least one circulator or stirrer for maintaining the circulation and mixture uniformity of the alkaline metal hydroxide.

6. The system of claim 1, further comprising a monitor for monitoring pH levels of the alkaline metal hydroxide and providing notifications and alerts when the pH levels are not within predetermined threshold levels.

7. The system of claim 1, further comprising a vacuum for extracting the precipitate from the container.

8. The system of claim 1, wherein the container includes a hatch or valve for removing the precipitate from the container.

9. The system of claim 1, wherein the body portion of the container collects a precipitate.

10. The system of claim 1, wherein the alkaline metal hydroxide is calcium hydroxide.

11. The system of claim 1, wherein the alkaline metal hydroxide is sodium hydroxide.

12. The system of claim 1, wherein the alkaline metal hydroxide is magnesium hydroxide.

13. The system of claim 1, wherein the volume of air containing CO₂ is obtained from the atmosphere.

14. The system of claim 1, wherein the volume of air containing CO₂ is obtained from an industrial process that produces CO₂.

15. The system of claim 1, wherein the precipitate is calcium carbonate.

16. The system of claim 1, wherein the precipitate is sodium carbonate.

17. The system of claim 1, wherein the precipitate is magnesium carbonate.

18. A method of reducing global warming, the method comprising:

providing a container having a quantity of an alkaline metal hydroxide;

introducing a volume of air containing CO₂ into the alkaline metal hydroxide to allow the CO₂ in the volume of air to react with the alkaline metal hydroxide;

reducing the amount of CO₂ in the volume of air in the presence of the alkaline metal hydroxide; and

releasing air having reduced CO₂ content from the container into the atmosphere.

19. The method of claim 18, wherein reducing the amount of CO₂ in the volume of air includes forming a precipitate.

20. The method of claim 18, further comprising collecting a precipitate in the container.

21. The method of claim 18, further comprising filtering the volume of air containing CO₂ through a filter having adsorbing material prior to introducing the volume of air containing CO₂ into the alkaline metal hydroxide to remove contaminant particles.

22. The method of claim 18, further comprising monitoring the pH level of the alkaline metal hydroxide.

23. The method of claim 18, further comprising controlling precipitate production by adjusting the pH level of the alkaline metal hydroxide.

24. The method of claim 18, further comprising replenishing the quantity of alkaline metal hydroxide when the pH level of the alkaline metal hydroxide drops below a predetermined level.

25. The method of claim 18, further comprising extracting the precipitate from the container.

26. The method of claim 18, further comprising purifying the precipitate by treating the precipitate with additional amounts of CO₂.

27. The method of claim 18, wherein introducing a volume of air containing CO₂ includes injecting the volume of air into the alkaline metal hydroxide under pressure.

28. The method of claim 18, wherein introducing a volume of air containing CO₂ includes finely dispersing the volume of air throughout the alkaline metal hydroxide under pressure.

29. A method of reducing global warming, the method comprising:

providing a quantity of an alkaline metal hydroxide;

introducing a volume of air containing CO₂ into the alkaline metal hydroxide to allow the CO₂ in the volume of air to react with the alkaline metal hydroxide;

reducing the amount of CO₂ in the volume of air in the presence of the alkaline metal hydroxide; and

releasing air having reduced CO₂ content into the atmosphere.
