SKYscrubbers and SEAscrubbers - Removing CO2 From The Air

Nuclear powered machines to suck climate changing CO2 back out of the air might be powerful enough to overcome the
 "The atmosphere is too big and the CO2 too dilute." issue sufficiently to take some of the edge off Climate Change's "PEOPLE KILLING" HOT summer days.

 

In many parts of the world, such as sub-Saharan Africa, there is also a need for significant increases in energy consumption to improve human development. One pathway to meet these twin challenges of alleviating energy poverty and minimizing greenhouse gas emissions is nuclear energy, writes Abigail Sah, Jessica Lovering, Omaro Maseli and Aishwarya Saxena.

Air Contactor Carbon Capture

Air Contactor
("Scrubber" is the correct engineering term for an apparatus that removes gas impurities from another gas - such as air - or liquids.
"Air Contactor" is the descriptive name this website has adopted for non-authorized explorations into variants of Carbon Engineering's air contactor.)

SEAscrubber Carbon Capture

A CO2-Capturing Flash SEAscrubber
Many flash desalinators can have carbon-capture added to it's early stages. There are more than 1,500 flash desalinators in the MidEast.
Some MidEast desalinators are capturing and returning a bit of the captured CO2 to their desalinated fresh water product to add "sparkle".

The chemistry for CO2 scrubbing is well-known. Climate Change CO2 in air is a trace gas of 400 parts per million.
To gather Climate Change stopping amounts of CO2 from the air demands huge air contactors. Lake surfaces are huge air contactors.

The CARBON CAPTURING implications of a nuclear powered flash desalinator using an alkaline lake such as Mono Lake, CA, are staggering.

 

Suitable CO2 Storage Sites.

 

MidEast Flash Desalinator. Powered by a nuclear reactor, isolated remote alkaline lake CO2 extractors this size could extract massive amounts of CO2 from the air.
Only the CO2-yeilding stages of the flash desalinator would be built.
The semi-fresh water produced by this process would be returned via water jets squirting high up into the air over the alkaline lake to absorb more CO2 from the air.
Engineers should note most of the objects are cylindrical in shape - leading to economy with structural integrity.
