NOVELTY - Capturing carbon dioxide to halt global warming by enlarging regions suitable for sugarcane plantation as a substitute for rain forest to absorb large quantity of anthropogenic carbon dioxide already in the Earth's atmosphere via photosynthesis, producing cane sugar, fermenting to fuel ethanol, and using the cellulose biogases, a biomass fuel for electricity generation without adding new carbon dioxide into atmosphere, comprises an improved Solvay process as depicted in figure-1 of the specification.    USE - The method is useful for capturing carbon dioxide to halt global warming.    ADVANTAGE - The method recycles half the carbon dioxide re-emitted during the process of calcining baking soda into soda ash back into the carbon dioxide scrubbing tower, thus producing twice as much soda ash and ammonium chloride when compared with the standard Solvay ammonia soda ash process.    DETAILED DESCRIPTION - Capturing carbon dioxide to halt global warming by enlarging regions suitable for sugarcane plantation as a substitute for rain forest to absorb large quantity of anthropogenic carbon dioxide already in the Earth's atmosphere via photosynthesis, producing cane sugar, fermenting to fuel ethanol, and using the cellulose biogases, a biomass fuel for electricity generation without adding new carbon dioxide into atmosphere, comprises an improved Solvay process as depicted in figure-1 of the specification, and calcining baking soda into soda ash in a kiln (104) equipped with a vacuum pump, removing air inside the kiln before calcining, thus rendering it possible to collect one-to-one mole ratio mixture of carbon dioxide and water suitable to be used as multi component working fluid producing high pressure difference in a wide temperature range of liquid-to-gas equilibrium, and to be useful as power source, from upper exhaust (101), and producing twice as much of soda ash and twice as much of ammonium chloride as products of commercial value by using a scrubbing tower (103) equipped with a bottom inlet (102), thus letting the one-to-one mole ratio of carbon dioxide and water to be re-scrubbed, where the ammonium chloride is a valuable fertilizer, to grow sugar, then fermented into fuel ethanol, co-produced bagasse useful as fuel for electricity generation without adding new anthropogenic carbon dioxide into atmosphere. INDEPENDENT CLAIMS are also included for:    (1) a distill water producing apparatus as depicted in figure-3 of the specification to produce fresh water from seawater to irrigate desert land into oasis suitable for growing sugarcane, and 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 25 billion tons of carbon dioxide annually from atmosphere, where the distilling apparatus is designed for greenhouse effect under desert-hot weather condition, comprising: a multitude of sealed off segments of enclosures with outer, larger diameter steel tube painted black outside and inside, and an inner, smaller diameter stainless steel tube painted black outside, which are sealed off on the two ends by segment partition plates, thus preventing hot air from escaping; a multitude of parabolic troughs with foci lines coincide with the inner tube; a separation tank that separates distilled water vapor from concentrated salt solution; a heat exchange unit that condenses the water vapor with external evaporation chilling; and a pump that pumps seawater through the smaller diameter stainless steel tube; and    (2) a pump as depicted in figure-2 of the specification, 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 which are short of rainfall but after receiving the pumped water, become suitable to grow sugarcane for fuel ethanol and cellulose bagasse biofuel, comprising: two reservoirs 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 associated with reservoir, and a heat exchange associated with reservoir that creates large pressure increment that powers the pump via hydraulic pressure difference; in association of reservoir, a movable piston; a rigid connecting rod connects pistons and on rod, one marker pin is mounted on the side of piston, away from the midpoint of rod by the stroke distance that piston travels, another marker pin is mounted on the side of piston by the stroke distance that piston travels; a location sensor mounted at the midpoint of the frame of the hydraulic press; an onboard electronic controller with storage battery pack and battery charging photovoltaic cell modules; a plastic lens pivoted through the lens center of gravity axis to save power consumption of moving the lens, as the location sensor made contact with the marker pin, where the electronic controller shall rotate the plastic lens away from focusing over the current heat exchange, and focus upon the heat exchange associated with the compressed reservoir; and 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 accordingly.
