Mainly because it\u2019s highly water-soluble, its cooling power is four times greater than that of the next-best salt, ammonium chloride. As an added bonus, ammonium nitrate is already widely utilized in fertilizer, and is quite inexpensive.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>There are many parts of the world which lack infrastructure, but that get a lot of sunlight \u2026 which makes buildings uncomfortably hot.
