Method and apparatus on halting global warming

Abstract

We have described herein a method and associated apparatus that can halt global warming with significant economic benefits. They include (1), re-scrub half the carbon dioxide emitted from calcining baking soda into soda ash to produce twice as much soda ash and twice as much ammonium chloride as comparing with the standard Solvay ammonia soda ash process; Use the ammonium chloride as sugarcane fertilizer producing fuel ethanol, and bagasse, a photosynthesized bio-fuel from carbon dioxide already presented in the earth atmosphere for power generation, and (2), expand the sugarcane plantation areas into desert oasis using desert heat to produce distilled water for irrigation, pumped by solar heated hydraulic press pumps to supplement insufficient rain forest resources on earth's continents to accelerate reaching “carbon neutral” on capture annually twenty five billion tons of anthropogenic carbon dioxide from earth atmosphere economically.

1 . To further enlarge regions suitable for sugarcane plantation beyond areas having heavy nature rainfall, to an extend large enough to reach “carbon neutral” by capturing twenty five billion tons of carbon dioxide annually from atmosphere, a distill water producing apparatus as depicted in  FIG. 3 , to produce fresh water from seawater to irrigate desert land into oasis suitable for growing sugarcane. Said distilling apparatus is designed to take advantage of greenhouse effect under desert-hot weather condition, further comprising:
 A. A multitude of sealed off segments of enclosures with outer, larger diameter steel tube  302  painted black outside and inside, and an inner, smaller diameter stainless steel tube  303  painted black outside, sealed off on the two ends by segment partition plates  304  and  305  to prevent hot air from escaping; 
 B. A multitude of parabolic troughs with foci lines coincide with said inner tub; 
 C. A separation tank that separates distilled water vapor from concentrated salt solution; 
 D. A heat exchange unit that condenses the water vapor with external evaporation chilling. And 
 E. A pump that pumps seawater through said smaller diameter stainless steel tube  303 . 
 
     
     
         2 . A pump as recited in claim  2 E, as depicted in  FIG. 2 , able to use solar heating as a free source of energy to pump water from one dry region to another dry region to enlarge areas where are short of rainfall but after receiving the pumped water, become suitable to grow sugarcane for fuel ethanol and cellulose bagasse bio-fuel, further comprising:
 A. Two reservoirs  202   a  and  202   b  that house the bi-component working medium consists of one-to-one mole ratio of carbon dioxide dissolved into water, while heated by solar heating via a heat exchange  203   a  associated with reservoir  202   a,  and a heat exchange  203   b  associated with reservoir  202   b,  creates large pressure increment that powers said pump via hydraulic pressure difference;   B. In association of reservoir  202   a,  a movable piston  202   c,  and in association of reservoir  202   b,  a movable piston  202   d;      C. A rigid connecting rod  205  connects pistons  202   b  and  202   d,  on rod  205 , one marker pin  206   a  is mounted on the side of piston  202   c,  away from the midpoint of rod  205  by the stroke distance that piston  202   b  travels, another marker pin  206   b  is mounted on the side of piston  202   d  by the stroke distance that piston  202   d  travels;   D. A location sensor  207  mounted at the midpoint of the frame  208  of the hydraulic press  201 ;   E. An onboard electronic controller with storage battery pack and battery charging photovoltaic cell modules.   F. A plastic lens  204  pivoted through the lens' center of gravity axis to save power consumption of moving the lens  204 , as the location sensor  207  made contact with the marker pin  206   a  or  206   b,  said electronic controller shall rotate the plastic lens  204  away from focusing over the current heat exchange, and focus upon the heat exchange associated with the compressed reservoir; And   G. An on-board software able to locate the location of the sun as a function of the date and time of the on board electronic watch, and pointing the lens  204  accordingly.
