With a two chamber system humans can pull CO2 out of the atmosphere in mass. Why are people, humans, overthinking this climate change thing.
The first chamber is pressurized to 65 PSI using atmospheric gases. Within this chamber is a cooling mechanism such as a heat pump that cools the ambient temperature to 40 degrees Fahrenheit. When this cooling and condensing happens water will naturally condense and become liquid. This liquid is waste and can be purified for drinking or discarded. The remaining gaseous solution is used as a feeder solution for chamber two.
Chamber two uses a compressor that ‘turns on’ when the internal pressure falls below 80 PSI and ‘turns off’ when the internal pressure reaches 92 PSI. A sister pressure valve ‘opens’ when the internal pressure reaches 92 PSI and ‘closes’ when the internal pressure reaches 79 PSI. A cooling mechanism maintains and internal ambient temperature of 60 degrees Fahrenheit. As the gaseous solution enters chamber 2 is cooled and condensed CO2 (and potentially some additional water) condenses into an aqueous solution. As the valve releases pressure the gaseous solution that is low in CO2 is released into the atmosphere and replenished with CO2 rich atmospheric gases.
When the height of liquid CO2 in chamber 2 reaches a predefined level the compressor automatically stops rotating gases until the liquid CO2 is drained. The liquid CO2 can be places in large chambers filled with minerals that will react to create carbon mineralization, could be purified for beverage use, or could be stored for potential chemical-generation of electricity.
If a couple solar panels are thrown into the mix and the chambers are placed in remote areas of high sunlight such as far north and far south the cost-to-cool and solar efficiency can be maximized to make this almost an autonomous system. Of course, automating the ‘dumping’ of the condensed water from chamber 1 would be required as would the pipeline from chamber 2 to the distribution point. Here’s a pretty low-tech picture that took very little time to create a rudimentary visualization of this idea.
