I don't believe in climate change or carbon credits myself I believe that to be a scam. I do believe in pollution and limited resources.
>My point wasn’t related to climate change; it was to consider how much CO2 is offgassed during the carbonate-to-oxide conversion of calcium..

Ok, I can see where you are going with this. My plan is to use my solar panels connected to my heating element to drive off the water from the
slated lime.... But as I watch the process It appears the lime needs co2 to go back to it's old state.... Perhaps putting the wet lime in a chimney
outside might work to get the co2 the slated lime may need to revert back to limestone? Not sure.
Yeah, I purchased some quicklime so my plan was not to do the conversion, but to add water to the quicklime, and measure the heat, then
experiment with the now slate lime to see if I can convert it back to quicklime if that is possible.... If it is not, then I will use it combined with
aluminum powder to cook my food with, as this is a proven recipe for cooking food.
>Okay, but just be aware that alum powder and aluminum powder are very different things. “Alum” is potassium aluminum sulfate, whereas “aluminum >powder” is metallic elemental aluminum in powder form.
>The type used in MRE warmers is aluminum powder, not alum.
You are correct.
>The other thing I’d caution about using quicklime + water for hand warmers is the amount of heat created and the tendency of the exothermic reaction >process to exceed 212°F / 100°C.
Yeah, My line of thought goes like this that I will put a small stainless steel bowel inside a larger one filled with water, the smaller one I will first water, then add the quicklime in small amounts so that it heats the bottom bowel water.... I plan on testing in very small amounts with a recording thermometer to get an idea of how much heat is given off with a given amount of water.
>Hydrating quicklime (also called “slaking”) can be dangerous and requires protective clothing and goggles.. because the heat it puts off can rapidly

Thanks for the heads up, the videos I watched demonstrated this... I will experiment outside wearing protective gear...
Not sure if this will work if not will use it as fertilizer or mortar.
