Can we convert the exhaust gas usefully ?

How does the environment behave with exhaust gas in vehicles, if their temp is being reduced before exhaust?If the exhaust gas passes through a similar setup to that of the radiator, and then if it gets exhausted, with a lower temperature, the heat will be less and exhaust gas temp should be less and the water vapor effect may differ.probably with some design change, this can be achieved, this link the windmill one somewhat relates to what I am saying https://science.howstuffworks.com/environmental/earth/geophysics/manufacture-water1.htmThis is more of a subject that is related to evaporation and fractional distillation. Where the liquids of different temperature, losses heat or based on the temperature they get settled in the columns. Given that, apart from sea, rivers, the major presence of water is combustion, where it is present as water vapor in the exhaust gas. Unlike the other experiments, where raw materials like hydrogen, oxygen will be used to form the cloud, so the water vapor which is one of the key factors for global warming can be put back into the water cycle. Hence the focus is to capture the water vapor from the readily available exhaust gas. We can imagine the earth as a huge fractional distillation column with varying temperature w.r.t. altitude, so the gases get settled at a different level. If the gases are cooled, their rise in the column gets affected there a good probability that clouds get formed at a lower altitude where absorption of sunlight and greenhouse effect gets reduced, because of both carbon and VPThe idea of separating the carbon and hydrogen can be done with a difference in temperature, given that carbon and water vapor has a difference in temperature. The idea of reducing the temperature of the exhaust gas can provide a probability of condensing or forming clouds at a lower altitude. The need is a better cooling system, with a coolant and air blast before the gas gets exhausted. The air captured can help in cooling the exhaust gas, though the fractional distillation of air is used to produce the industrial nitrogen and oxygen, still Water vapor and carbon dioxide are removed because they solidify at low temperatures, within the mixture of carbon dioxide and water vapor still there is a difference in temperature, that can serve to get separated at different level.Just an experiment, with the usage of coolant in thermodynamics lab, could help to study the behavior of these gases on the environment.Probable exhaust system, modified:Usage of diluted isopropyl alcohol before the gas being let offhttps://blog.gotopac.com/2017/05/15/why-is-70-isopropyl-alcohol-ipa-a-better-disinfectant-than-99-isopropanol-and-what-is-ipa-used-for/Most of the air-conditioning topics need to be used for this setup,ref: https://www.youtube.com/watch?v=onvokzYlRR0&ab_channel=LinwoodStarlinghttps://www.youtube.com/watch?v=2265UNflXT4&ab_channel=grayfurnacemanPsychrometry analysis needs to be done, the temperature from the normal exhaust gas and with modified air-cooled exhaust gas/coolant exhaust gas needs to be calculated. Some assumptions need to be considered as in Air-conditioning and refrigerators as well.Few questions to people who are researching :few clarifications, how far https://www.quora.com/How-much-water-is-formed-by-the-combustion-of-1-litre-of-petrol is correct, at least in theory this looks to be correct, and even if we consider the efficiency of the engine, if we assume if 20 or 10 % is what Vapor gets released, still it is an good amount of water given that so many vehicles are running around the city, and consuming a lot of gasoline.As per assumption, Open system is assumed to be a heat sink, which may not be true given that at one point heat can't be dissipated due to the greenhouse gases. Have you come across any paper on the effect of greenhouse gases w.r.t altitude? I mean how these gases react when the altitude is less. Air at higher altitude is dry, less of water vapor, but VP content would have raised because of global warming even in higher altitude, so if the temperature of this VP in the exhaust is reduced, there may be a possibility of reducing global warming effect and probability of changing them to cloud.In the video https://www.youtube.com/watch?v=MtMmgcZoTSA, what is the role of alcohol? Is there any other substitute for this especially for a hot exhaust gas? as it is flammable and if we use a diluted solution 70% rubbing alcohol will it help in some way?PV=nRTIf the pressure is reduced after opening the cap of the bottle, volume inc and water vapor changed to the cloud, ideally the same can be achieved as per my assumption by reducing temperature, do you think this is correct?Importance of radiator study in cooling:https://www.researchgate.net/publication/256718727_A_review_on_air_flow_and_coolant_flow_circuit_in_vehicles'_cooling_systemWith a high speed, the motion we need to see how the air flows in the pipes, without creating the coolant pipes. Probably aerodynamics needs to be applied, more related to F1 cars.ref:Cloud formation in a bottle:https://www.youtube.com/watch?v=cXpuo3YHOn0how many liters of water can be produced from petrol:https://www.quora.com/How-much-water-is-formed-by-the-combustion-of-1-litre-of-petrolCan water be produced by combustion, pros, and cons:https://chemistry.stackexchange.com/questions/55664/why-dont-we-produce-water-from-combustionFractional distillation of air:http://www.dynamicscience.com.au/tester/solutions1/chemistry/gas/fractionaldistilationofair.htmhttp://www.minsocam.org/ammin/AM69/AM69_319.pdf
