Farm Area Big Enough To Stop The Entire World's Climate Change:
(See Example Below)
21,736 2 mile x 2 mile (4-square-mile)
plots of arid land. About the same land area as
Minnesota - (86,943 square miles).
5,280 sq = 27,878,400 x 4 =
111,513,600 sq ft/plot

One very rough
estimate indicated 21,736 2 by 2 -mile-square plots (about 86,943 square miles, 4
inch thick), with each plot harvested at the rate of .01 square mile per day, 365
days per year, would be needed to stop climate change in it's tracks.
This was an estimate made to determine the pebble mass dwell of a 100 foot wide
harvester. (Recall: Today's airplanes don't look much like the first
airplanes.) Check back for both revisions and corrections.

shelling the corn, putting it in a hopper, disposing of the stalk stover.

The Global Positioning System (GPS) is a U.S.-owned
utility that provides users with positioning, navigation, and timing (PNT)
services. This system consists of three segments: the space segment, the control
segment, and the user segment.

"standing in" for future images of yet-to-be-engineered perhaps 100 foot wide
Climate Change combine harvesting machinery. They would never travel on roads.
Located only in dry deserts, they would be supported by tanker trucks during the
inactive night hours. Tracked vehicles steer by doing maneuvers called
"Skid-Steer or Neutral Steer" and could be parked overnight in sheds the size of
small airplane hangars.)
How about a stiff plastic
screen laying on basket-ball sized rocks as a surface for CO2-loaded
magnesium carbonate pebbles to weather and to support a broad-tracked CO2
When weathered, the pebbles
would be vacuumed up into a mobile calciner, their CO2 extracted, and, after
cooling, the resulting magnesium oxide pebbles would then be returned to the
plastic screen covered rocks?
A 100 foot-wide mobile calciner might resemble one of today's GPS-guided
swing-arm corn or wheat harvesters and be able to precisely process 100 foot
wide swaths of magnesium carbonate pebbles at a walking pace. This is how wheat
farmers tackle Minnesota-size wheat harvests. It would have to be able to
harvest 1 square mile in a 10 hour day.
Check out this sweeper demo idea as a way to corral and vacuum up weathered
magnesite pebbles for calciner reprocessing:
Warning! When fresh,
these CO2-capturing pebbles are caustic magnesium. Once
they have absorbed their fill of air's CO2, they are no
longer caustic. Airtight combine cabs may be needed.

It would certainly be much more efficient for mobile harvesting machinery to go
to the CO2 rather than hauling a 90 mile square of loose pebbles to a central
Many smaller harvesting machines going over smaller fields of pebbles.
Asian farm machinery builders are likely to come up with the best early field
machinery designs for this application.
A large powered magnesium carbonate harvester might be smaller than a semi
trailer and it could do a linear sweep. Gasoline-sized tank trucks could bring
fuels and liquid oxygen and carry away the liquefied CO2.
Or perhaps a chemical processing site on a 100 foot wide 1/4 mile long bridge
mounted on railroad tracks or a huge crawler like that machine used at Cape
Canaveral to haul large rockets from the assembly building to the major Launch
Many smaller scale iterations of the machinery will need to be made at first to
find the most efficient designs and construction techniques.
Recall the enormous bursts of construction that has occurred in times of
vigorous economic expansion such as the massive economic competition between
Capitalism and Communism that occurred after World War II?

Earth back down to normal.
